A method of making a resilient unit includes inserting a spring (2300) into a block (2100). A rotatable cutter tool (2500) comprises a cylindrical spring support (2510) onto which is placed a spring (2300), the length of which is slightly greater than the support (2510). The support (2510) is magnetic and the spring is held in place on the support by magnetism. The support (2510) comprises a substantially hollow metal tube, the leading edge of which (2510a) comprises a sharp cutting edge. As the rotating tube (2510) advances towards the block (2100), it begins to make a cut or discontinuity in the material of the block for the spring (2300) to occupy. Once the cut is sufficiently deep to accommodate the spring, the cutter/support is withdrawn, leaving the spring inside the block where it is lightly gripped due to the diameter of the spring being slightly greater than the cut made by the cutter. Note that substantially no block material is removed by the cutting. Rather, the block material is parted or displaced by the cutting edge, leaving behind a cylindrical-shaped discontinuity for the spring. Leaving the block material in place is beneficial because it avoids wasting material and also the material left in place can contribute to the resilience of the unit and optionally act as a damper for the action of the spring.
A demountable, recyclable mattress frame is provided for a mattress (100) which has a resilient core (110) comprising an array of metal coil springs in individual pockets (not shown) On each of the major upper, and lower, surfaces a the demountable frame (120) helps to maintain the core's shape. The frame (120) is joined to the core by a plurality of hog rings (130) that pass around the frame and penetrate the pocketing material to engage one or more coils of the springs within (not shown). The frame (120) comprises four frame members (122) and four frame connectors (124). In this embodiment, the frame members (122) comprise hollow steel rods and the connectors (124) are of a hollow plastics material. The frame members and connectors are dimensioned such that the former can slide into the latter to varying degrees and be held there in a friction fit.
A string comprises springs 1100 (one is shown in broken lines) encased within pockets formed between leaves/plies/positions 1200 of pocketing material joined together between the springs at positions P, and at edges E and top seam S The joining of the leaves 1200 is done by ultrasonic welding. Whereas the welds P between the pockets and at the edge E are substantially continuous, the weld forming the top seam S is intermittent, i.e., the weld has spaces where there is no fusing of the pocketing material. This is depicted as a broken line in the drawing.
The unit comprises an array of first coil springs (310) that are held in pockets formed between axially superposed sheets (320) of pocketing material that extend across plural rows of springs and are joined at positions P between the springs (310) and also at the edges of the sheets. The joining is, in this example, by ultrasonic welding of the pocketing material ( itself, in this case a nonwoven material, such as spun-bond polyester) and is shown as intermittent lines.The springs (310) are arranged in a grid-like pattern and a cluster C of four adjacent springs (one example shown shaded in the drawing) has within it a space S which is occupied by a second type of spring (330). In this case, the second type of spring (330) is a spring of smaller diameter. As they occupy the spaces S within the clusters C of first springs, the second springs (330) are arranged in positions that are offset from the first springs (310) in both X and Y axes.
A method of forming a resilient unit, such as a mattress core, comprises successively joining together a plurality of discrete strings of pocketed springs, side to side, to build an array of such springs, wherein successive discrete strings are introduced to the array alternately from substantially opposed directions. A first string (130a) of springs (110) is brought from a left side of the drawing towards the centre in the direction of arrow A1. A second string (130b) is then brought from the opposite side, in the direction of Arrow A2. Ultrasonic welding tools then join the strings together.

A method of making a resilient unit comprises arranging integral pocketed resilient elements in clusters, wherein each integral pocketed resilient element in a cluster is attached to at least one other integral resilient element, and wherein the clusters define spaces or interstices, and inserting an independent resilient element into one or more of the spaces or interstices The independent spring (260) is, in this example, a pocketed coil spring of an axial length slightly shorter than the springs (110) (only one of which is shown) making up the cluster (240), and of a smaller diameter. The length and diameter of the independent spring (260) may be different, according to the required characteristic of the resilient unit as a whole. In order to insert the independent spring (260), an inserter device (270), is first placed substantially vertically above the interstice. The device (270) comprises a hollow inserter tube (270a) with a frusto-conical funnel portion (270b) at its upper end, and an inner guide pole (270c), with a dome-shaped (alternatively conical) leading end (270d) projecting slightly beyond the end of the tube (270a). The tube (270a) and guide pole (270c) are almost the same diameter, with the latter being a close fit within the former. To insert the independent spring into the cluster, the device (270) is first inserted into the interstice (250), both pole (270c) and tube (270) together, with the dome-shaped leading end (270d) of the pole helping to ease the way past the coils of adjacent springs in the cluster.

A single, continuous coiled spring, generally at 400, is formed into two distinct spring portions 400A and 400B, of generally constant pitch, separated by a transition portion 450 approximately half-way along the spring 400. The transition portion 450 comprises at least one turn which is of a reduced pitch in the example, but which may be of a zero pitch or even a negative pitch. The spring is encased in a continuous pocket P. In this case, the transition portion 450 includes a substantially flat turn. The spring portions 400A and 400B comprise a common portion of spring material in this case spring wire and the coils are substantially continuous throughout the overall spring 400.
A spring transfer apparatus is shown generally at 1000. The apparatus comprises a wheel-like placement member 1100 which, in use, is driven to rotate in the direction of Arrow A1 about a central hub 1110 by a motor (not shown). The placement wheel 1100 has a plurality of circumferentially spaced spoke portions 1120 defining therebetween a series of spring chambers 1130. A magnetic base plate 1200 is arranged beneath the wheel 1100 and is arranged to receive a coil spring S which is deposited by a spring forming apparatus (not shown) of a known type, located above the plate 1200. As the wheel rotates, the spring is urged by the spokes 1120 along the magnetic base plate 1200 towards an arcuate compression stage 1300, comprising a pair of plates 1310 and 1320 that are axially spaced above and below the spring. The plates initially converge in a chamfer in the direction of rotation of the wheel 1100 causing the springs to become partly axially compressed as they transit between the plates. As the springs exit the plates, they are urged by the spokes into positions between a pair of superposed driven endless belts 1410 and 1420 between which the springs are further compressed and then conveyed to a pocketing station (not shown) where they are inserted into pockets for incorporation into a resilient spring unit, such as for use in a mattress core. The belts are optionally castellated to maintain a good grip of the springs.

In use, the wheel is driven to rotate in the direction of Arrows A1. At their distal ends, the spokes pass through a slotted compression chute (240) and the springs S located between the spokes become compressed during their passage through the chute. When the springs reach the lowermost point in the rotation, at which they are maximally compressed, the springs are pushed axially with respect to the hub (210) towards pre-prepared webs W of pocketing material that have been joined together at locations L to form pockets P for receiving the springs and which are travelling in the direction of Arrow A2.

14 ABSTRACT5 A resilient unit 1000 comprises two outer portions of spacer fabric 1100 and 1200 and a resilient core 1300 therebetween. The resilient core comprises an array of resilient elements which are in this example metallic coil springs S in 10 individual pockets P. The portions 1100 and 1200 of spacer fabric are joined together along the edges of the unit 1000, for example by ultrasonic welding at W, though other methods of joining the 15 portions 1100 and 1200 could be employed. (Figure 1)
An apparatus for welding together webs, the apparatus comprising first and second weld tools, wherein at least the first weld tool is rotatable about an axis of rotation and has a substantially cylindrical surface on which is located a welding contact portion, and wherein the welding contact portion extends at least partly circumferentially around the cylindrical surface and at least partly axially along the cylindrical surface.
A method of making a resilient unit includes inserting a spring (2300) into a block (2100). A rotatable cutter tool (2500) comprises a cylindrical spring support (2510) onto which is placed a spring (2300), the length of which is slightly greater than the support (2510). The support (2510) is magnetic and the spring is held in place on the support by magnetism. The support (2510) comprises a substantially hollow metal tube, the leading edge of which (2510a) comprises a sharp cutting edge. As the rotating tube (2510) advances towards the block (2100), it begins to make a cut or discontinuity in the material of the block for the spring (2300) to occupy. Once the cut is sufficiently deep to accommodate the spring, the cutter/ support is withdrawn, leaving the spring inside the block where it is lightly gripped due to the diameter of the spring being slightly greater than the cut made by the cutter. Note that substantially no block material is removed by the cutting. Rather, the block material is parted or displaced by the cutting edge, leaving behind a cylindrical-shaped discontinuity for the spring. Leaving the block material in place is beneficial because it avoids wasting material and also the material left in place can contribute to the resilience of the unit and optionally act as a damper for the action of the spring.

CUSTOMISABLE RESILIENT UNIT AND METHOD OF MANUFACTURE
A pocketed resilient unit (130), such as for a mattress core, comprises integral pocketed resilient elements (110) arranged in clusters (240), wherein each integral pocketed resilient element in a cluster is attached to at least one other integral pocketed resilient element, and wherein the clusters define interstices (250), in at least some of which are located independent resilient elements (260).
Apparatus for forming a resilient unit comprises a conveyor (210) and first and second spring supply stations (212 and 214), arranged in use to deposit respectively first and second spring types (216 and 218) under compression onto the conveyor. The conveyor is arranged in use to convey a row of the springs (216, 218) in a direction shown by Arrows A4 towards pocketing station (220). At the pocketing station (220) the springs are urged from the conveyor into positions between upper and lower sheets (222 and 224), by a plurality of inserter devices (226) that move together in a reciprocating fashion in the direction of arrow A5, before retracting to the position shown. After each row of springs is inserted between the sheets (222), upper and lower computer-controlled welding tools (not shown) come together at positions P between the springs to join the sheets together, forming pockets in which the springs are encased. After each welding event the resilient unit is indexed forwards a distance equal to one pocket width in the direction of Arrows A6 by computer-controlled drive means (not shown). The next row of springs is then conveyed into position ready for insertion between the sheets of material, and the process is repeated. The two spring supply stations are arranged to supply springs that differ from one another in at least one characteristic.

A pocketed spring unit comprising an array of springs (120) located in pockets (180) formed by discrete superposed webs (140) of pocketing material joined together by welds W between the springs, wherein the welds are located at alternately opposite ends of the pocketed springs. Figure (1) shows generally a pocketed spring unit at a first stage of manufacture. A row of coil springs (120) (only the end one of which is visible) is introduced by an inserter mechanism (130) into position between axially disposed webs (40a and 140b) of pocketing material. The webs (140a and 140b) are fed from supply reels (not shown via guide rollers (150). The springs (120) are partly compressed and are pushed between plates (160) towards the webs (140) by the inserter (130) in the direction of Arrow A1. Once the springs are between the webs (140) a pair of ultrasonic welding tools (170a and 170b) joins the webs together at weld locations W between the springs to form individual pockets (180) for the springs. One of the tools is a sonotrode/horn and the other is a base/anvil. Successive rows of springs are encapsulated by welds W that alternate between the axial ends of the springs, so that one is at an upper axial end and the next is at a lower axial end. The webs (140) may also be welded together along their edges (not shown) –i.e. at the ends of the rows –and between adjacent springs in the same row, to fully form the pockets.
A resilient unit has strings of individual coil springs (not shown) inside pockets 120 are arranged in an array. The strings together form a spring unit and are each secured to a common cover sheet S, which comprises a non-woven elastic fabric. It is welded ultrasonically or thermally whilst under tension in one or both of its major dimensions—i.e. in-plane—to the pockets 120, the material of which is substantially inelastic and non-woven. In this example the welds, labelled W, are located substantially centrally with respect to the generally circular end surfaces of the pockets.
An apparatus for welding a resilient unit is shown generally at (200) and comprises a first tool, in the form of a sonotrode –or "horn" –(210) and a second tool, comprising an anvil (220). Between the welding tools (210) and (220) are located the sheets 130of material to be welded, as a workpiece. The material may be of any weldable type, but for the purpose of making pocketed spring units it is often of non-woven, spun- bonded polyester. The sonotrode tool (210) comprises a bracket (210a) and a rotatable wheel (210b) which is arranged to rotate with respect to the stationary anvil (220). To effect welding an electrical current is applied to the sonotrode which causes it to vibrate at ultrasonic frequencies, typically in the region of 20 KHz. In combination with applied pressure, this causes highly localized friction in the sheets (130) which heats the material locally and welds the sheets together. As the wheel moves across the sheets (130) in the direction of arrow A, whether between adjacent springs or at the edge of the unit (100), the welding tools join the sheets together.
Apparatus for forming wire components, which are in this example springs, comprises a supply station (202), for supplying spring forming material, such as metallic wire W. The supply station includes a pair of guide rollers (204) and pair of driven feed rollers (206), mounted on a heavy support plate (216). The wire is fed through a flexible sheath FS to a remotely located wire shaping device, in particular a spring forming device 208, comprising forming tools (210), a pitch control tool (212) and a cutter (214). The forming tools (210) and the pitch control tool (212) form the wire into a spring S, which is cut from the supply of wire when it is complete. The tools (210, 212) and cutter (214) are controlled remotely from a control station (220) via a bundle of flexible control cables (222), which may include a power cable. The spring forming device 208 is mounted on a positioning member (224), such as a robot arm or moveable table, configured for three-dimensional movement, and/or optionally adjustments in inclination. Without the heavy plate (216) and rollers (205, 206), the spring forming device (208) is sufficiently light in weight and compact as to be moved by the positioning member (224) to a location in which springs are to be used, thereby avoiding the need for transportation apparatus to convey the springs from the place where they are formed to the place where they are to be used.

POCKETED SPRING UNIT AND METHOD AND APPARATUS FOR FORMING THE SAME
A pocketed spring unit comprises a plurality of strings of pocketed springs (110) and a cover sheet (140), wherein each string comprises a flap (150) of material located along an edge of the string and extending longitudinally of the string. The cover sheet is attached to the flaps at welds W.
Apparatus for forming a pocketed spring unit, comprising a plurality of strings of pocketed springs and at least one cover sheet, comprises welding tools for welding together the pocketing material and the sheet. One of the welding tools (200) is provided with a cutter (230) for cutting the pocket prior to welding. The tool (200) travels in the direction of Arrow Al, so that the cutter (230) penetrates the pocketing material substantially centrally at the circular proximal end face 160 of the pocket (110a). Once inside the pocket (110a), the tool (200) moves axially through the centre of the spring (120) until it reaches the distal end face (150) of the pocket. Before the end face (150) is reached, the piercing member becomes retracted in the direction of Arrow A2, so that the blade does not pierce the distal end face (150) of the pocket (110a).
A resilient unit (180), such as for a mattress, comprises a folded pad containing rows of resilient elements (120) in discrete pockets formed between superposed sheets of material joined at locations between adjacent resilient elements. Between at least some adjacent resilient elements the sheets form a gusset (160) which acts as a hinge when the pad is folded to form the resilient unit.
A resilient unit has strings of individual coil springs (not shown) inside pockets (120) are arranged in an array. The strings together form a spring unit and are each secured to a common cover sheet S, which comprises a non- woven elastic fabric. It is welded ultrasonically or thermally whilst under tension in one or both of its major dimensions - i.e. in-plane - to the pockets (120), the material of which is substantially inelastic and non- woven. In this example the welds, labelled W, are located substantially centrally with respect to the generally circular end surfaces of the pockets.
A conveyor (400) for transporting articles, such as coils springs, is described. The conveyor comprises a substrate (420) for supporting articles during transportation, and a plurality of retaining members (520) located on the substrate for retaining the articles during transportation. The retaining members (520) each comprise a mounting portion (530) for mounting to the substrate (420). A containment portion (540) comprises proximal and distal parts (540a) and (540b) define a space therebetween for receiving a coil spring (100) under compression. Slots (550a) and (550b) in the containment parts are aligned for receiving pushers.
Apparatus for forming wire components, which are in this example springs, comprises a supply station (202), for supplying spring forming material, such as metallic wire W. The supply station includes a pair of guide rollers (204) and pair of driven feed rollers (206), mounted on a heavy support plate (216). The wire is fed through a flexible sheath FS to a remotely located wire shaping device, in particular a spring forming device 208, comprising forming tools (210), a pitch control tool (212) and a cutter (214). The forming tools (210) and the pitch control tool (212) form the wire into a spring S, which is cut from the supply of wire when it is complete. The tools (210, 212) and cutter (214) are controlled remotely from a control station (220) via a bundle of flexible control cables (222), which may include a power cable. The spring forming device 208 is mounted on a positioning member (224), such as a robot arm or moveable table, configured for three-dimensional movement, and/or optionally adjustments in inclination. Without the heavy plate (216) and rollers (205, 206), the spring forming device (208) is sufficiently light in weight and compact as to be moved by the positioning member (224) to a location in which springs are to be used, thereby avoiding the need for transportation apparatus to convey the springs from the place where they are formed to the place where they are to be used.
A resilient unit (180), such as for a mattress, comprises a folded pad containing rows of resilient elements (120) in discrete pockets formed between superposed sheets of material joined at locations between adjacent resilient elements. Between at least some adjacent resilient elements the sheets form a gusset (160) which acts as a hinge when the pad is folded to form the resilient unit.
A method of forming a pocketed spring unit for an upholstered article comprises taking successive strings of pocketed springs and welding at least one sheet of material to at least a first end of the pocketed springs. Anvils 46 are moved from a non-operative position to an operative position, in which they are located between adjacent pockets at upper and lower ends of the springs. This embodiment makes use of the surplus material that is formed at the ends of the pockets in the form of flaps or “ears” of material. These flaps protrude upwardly initially, and then become folded flat as the spring unit advances between the rolls 48 of material.
The external anvils are then made to apply heat and pressure to the material flaps trapped between them and the internal anvils at the sides of the pockets, between the springs to weld them to the material from the rolls 48.
A complex spring unit (10) comprises at least a first spring portion (12) and a second spring portion (14), which first and second spring portions are integrally formed, wherein the first spring portion is arranged in use to be placed under compression, and the second spring portion is arranged in use to be placed under tension, during compression of the complex spring unit.

A resilient unit suitable for providing comfort, convenience, support or protection is described. The unit typically takes the form of a pad comprising a plurality of pocketed coil springs arranged in an array, each spring being substantially encased in an individual pocket, and the unit being compressible in the axial direction of the springs, wherein each spring comprises a number of coils, and in respect of at least some springs the coils at opposed ends are of different diameter.
