In a method for optimising settings of a yarn joining device, a sample of yarn joins is produced by the yarn joining device with unchanged settings. Values of at least one parameter of the yarn joins of the sample are measured (313). A characteristic value of the sample is calculated (315) by means of a statistical evaluation of the measured parameter values and assigned to the current settings. The characteristic value is calculated (315) in a vector space spanned by the at least one parameter. A setting of the yarn joining device is changed (317). The preceding steps are repeated for at least one further sample. By comparing the characteristic values of the samples, optimum settings are determined (318). The determined optimum settings are set (319) on the yarn joining device. The method allows more robust, systematic and targeted optimisation of the settings.

In the method for optimizing a spinning process (1) with regard to foreign materials, a flow of fibre tufts, which are carried along pneumatically in an air flow, is monitored for foreign materials at a first station (11) of the spinning process (1). On account of the monitoring, foreign materials are separated out from the flow of fibre tufts on the basis of a separation criterion. At a second station (14) of the spinning process (1), which is located downstream of the first station (11), yarn that has been spun from the fibre tufts and is carried along in its longitudinal direction is monitored for foreign materials. On account of the monitoring, the foreign materials detected in the yarm are classified into at least two classes on the basis of at least one property of the foreign materials. A share of the foreign materials in at least one of the at least two classes in a total amount of the foreign materials detected in the yarn is determined. The separation criterion is modified depending on the share of the foreign materials in the at least one class. In this way, the spinning process (1) is optimized with regard to foreign materials.

The method is for monitoring contamination in a stream of fiber flocks transported pneumatically in an airflow. Characteristics of entities, including contamination, in the stream of fiber flocks are detected and evaluated. Values of a first parameter and a second parameter of the entities are determined from the characteristics of the entities. An event field (200) is provided, which contains a quadrant or a part of a quadrant of a two-dimensional Cartesian coordinate system, wherein a first axis (201) defines the first parameter and a second axis (202) defines the second parameter. The values of the first parameter and the second parameter determined for an entity are entered in the event field (200) as coordinates of an event (203, 204) representing the entity. Thus, entities can be handled in a differentiated way.
The invention relates to a method for monitoring a fiber stream (9) of a fiber material, in which the fiber material is monitored. According to the invention, a dissolution degree of the fiber material is determined, which indicates how well the fiber material is dissolved into individual fiber flocks. The dissolution degree can represent a control variable in a control circuit (7), and an actuating variable which is dependent on the dissolution degree can influence the opening of the fiber stream (9). The fiber material is thus optimally dissolved.

Slots for the functional modules (41-46) are arranged on the turret-like setup in such a way that each functional module (41-46) is insertable into one of the slots from the front (11). Each functional module (41-46) is detachably fastened in one of the slots by means of fastening means (91) which are accessible from the front (11). As a result, the tester (1) can be adapted more easily to changed circumstances.
The modular tester (1) serves to test elongate textile test material. It has a test material path (12) and a turret-like setup with a multiplicity of functional modules for measuring various parameters of the test material arranged in succession along the test material path (12). A number of functional modules within the turret-like setup are directly connected to one another in a gas-conducting manner such that, together, they form a ventilation group, in the interior of which a common interior volume is present. The ventilation group has a central ventilation unit (6) which is embodied to ventilate all functional modules of the ventilation group and which contains at least one central ventilator (61-63) for establishing positive air pressure in the common interior volume. Deposits at the sensors are thus avoided. The tester (1) is easily adaptable to changed circumstances, cost-effective, quiet and has a long service life.
The modular testing device (1) is used to test elongated textile testing materials. The testing device has a testing material path (12) which runs along a front (11) of the testing device (1) and a tower-like structure with a plurality of functional modules (41-46) which are arranged one behind the other along the testing material path (12) for measuring different parameters of the textile testing material. A front cover (6) is secured to the tower-like structure in a rotatable manner such that the cover can be rotated from a closed state, in which the structure at least partly covers a plurality of the functional modules (43-46) from the front (11), to an open state, in which the structure makes said functional modules (43-46) accessible from the front (11), and back. The testing device (1) is easy to maintain and simultaneously protects the functional modules.
An electrode assembly (5) for capacitively testing an elongated textile material comprises an electrode (64) as part of a measuring capacitor for capacitively testing the elongated textile material.

The invention relates to a conveyor device (2) for a test unit for testing elongated textile test material, comprising a motor (30) and a pair of conveyor rollers (41, 42) that interact to convey the test material. The outer surfaces of the conveyor rollers can be pressed against one another. At least one of the two conveyor rollers (41, 42) is operatively connected to the motor (30) in order to be rotationally driven. At least one (42) of the two conveyor rollers (41, 42) is movably mounted in the direction perpendicular to the axis (44) of said conveyor roller. The conveyor device comprises a passive opening mechanism, which continuously drives the two conveyor rollers (41, 42) apart, and an operable, active closing mechanism, which, upon actuation, drives the two conveyor rollers (41, 42) against each other and overcomes the effect of the passive opening mechanism. By virtue of the fact that the passive opening mechanism keeps the two conveyor rollers (41, 42) apart in their idle state, pressure points in the conveyor rollers (41, 42) are prevented and the service life of the conveyor rollers (41, 42) is extended.

The conveying device (2) for an inspection device for inspecting elongate textile material to be inspected contains a motor (30) and a pair of conveying rollers (41, 42), which conveying rollers interact in order to convey the material to be inspected. The lateral surfaces of the conveying rollers can be pressed toward each other. Both conveying rollers (41, 42) are operatively connected to the motor (30) for the rotational driving of the conveying rollers. An operative connection of at least one (42) of the two conveying rollers (41, 42) to the motor (30) contains a frictional connection not achieved by means of the lateral surfaces of the two conveying rollers (41, 42). The two conveying rollers (41, 42) and the frictional connection are designed in such a way that a torque caused by a maximum static friction force acting between the lateral surfaces of the two conveying rollers (41, 42) is greater than a torque caused by a maximum static friction force acting in the frictional connection. The slip is thereby shifted from away from the output side toward the drive side. The conveying rollers (41, 42) are treated gently, and the travel of the material to be inspected is improved.

DETERMINATION OF FAULT CAUSES IN A PRODUCTION PROCESS OF AN ELONGATED TEXTILE STRUCTURE
The method is used to determine fault causes in a production process of an elongated textile structure. Measured values of a property of the structure are detected along the longitudinal direction of the structure. Values of a parameter of the structure are determined from the measured values. An event field (3) which contains a quadrant of a two-dimensional Cartesian coordinate system is provided, the abscissa (31) of which indicates an extent (l) of parameter values in the longitudinal direction and the ordinate (32) of which indicates a deviation (ΔΜ) of the parameter from a target value. Densities of events in the event field (3) are determined from the values of the parameter and the extent (l) of said values in the longitudinal direction. In the event field (3), two density lines (41, 42), which are substantially constant but follow different event densities, are calculated. The curves of the two density lines (41, 42) are compared with each other. A fault cause is inferred from a significant deviation of the curves from each other. Thus, the causes of any faults can be determined, regardless of the periodicity thereof.

DETECTION OF A PERIODIC STRUCTURE IN A MOVING ELONGATED TEXTILE MATERIAL
In a method for detecting a periodic structure in a moving elongated textile material (9), said textile material (9) (e.g. yarn) is sampled simultaneously at multiple detection points (43.1-43.5) located equidistantly in the longitudinal direction (91) of said material. Sampling signals that can be detected at the detection points (43.1-43.5) are added to form a composite signal (for example by means of an integrated optical waveguide structure.) Temporal changes in the composite signal are indicative of a periodic structure in the textile material (9). A localised spectrum of the structure of the textile material (9) can be obtained (Fourier spectrum) with multiple groups of multiple equidistant detection points (43.1-43.5) with practically no computational effort.

Disclosed is the use of a substrate (2) comprising at least one optical waveguide structure (4) integrated therein for the optical inspection of a moving textile material (9). A sampling region (3) for optically sampling the textile material (9) is provided on the substrate (2). The optical waveguide structure (4) opens at least partially into the sampling region (3). A device (1) thus constructed requires little space, has various applications and can be modified or serviced easily.
The invention relates to a method for determining the hairiness length distribution of a yarn, in which the hairiness lengths are measured (602) on the yarn. Results of the hairiness length measurements are stored. Categories of hairiness lengths are automatically formed (603) as a function of the results of said hairiness length measurements. A frequency distribution of the measured hairiness lengths is issued (604) in the form of a diagram based on the categories formed automatically. This flexible categorisation also allows the hairiness length distribution to be determined for yarn types that are non-typical.
In the method for characterizing the hairiness length distribution of a yarn, hairiness lengths on the yarn are measured (101). Hairiness lengths resulting from the hairiness length measurements (101) are stored (102). A ranking list of the stored hairiness lengths is established (103). The ranking list is numerically specified (104). At least one value of the numerical specification is output as a characteristic for the frequency distribution (105). Such characterization is simpler than by means of the previously conventional hairiness length classes.
The invention relates to a method which is used to characterize an optoelectronic measuring unit (1) for textile material to be inspected, which unit having an optical path for measuring light (17) used during measuring. A substantially flat test specimen (2), which is neither a copy or an imitation of the material to be inspected is introduced into the optical path. The test specimen (2) is measured by means of the optoelectronic measuring unit (1). This allows the optoelectronic measuring unit (1) to be characterized and/or adjusted more easily and more comprehensively than previously.
The present invention discloses a device (1) for photoelectrical monitoring the rotational movement of a yam (13) in a ring-spinning unit (10). The device is mounted above a spindle (16) of the ring- spinning unit. It comprises a housing (26) and a yam guide (14) for guiding the yam (13). A light emitter (21) is mounted within the housing (26) and is adapted to emit a beam of light (25) toward the yam (13). A light receiver (22) is mounted within the housing (26). The light emitter (21) and the light receiver (22) are mounted in juxtaposition with each other, and the light receiver (22) is adapted to receive light emitted by the light emitter (21) and reflected by the yam (13). The invention offers the advantages of small size, low cost, easy installation, easy replacement and immunity to electromagnetic- interference.

CHARACTERIZATION OF REGULAR EVENTS IN AN ELONGATED TEXTILE TEST MATERIAL
The invention relates to a method for characterizing at least one category of regular events in an elongated textile test material, whereby values of at least one parameter of the test material are determined. Events in the test material which have parameter values that deviate from a rated value are statistically examined with respect to a regular occurrence. In an event field (4) at least one category of events is formed which occur substantially regularly, which have substantially the same extension (L1, L2) of parameter values and which have substantially the same deviation (ΔΜ1, ΔΜ2) of the parameter from the rated value. The category is entered in the event field (4) as a coherent surface area (51, 52) the position of which is defined by the extension (L1, L2) they have in common and by the deviation (ΔΜ1, ΔΜ2) they have in common and which has an additional feature (d1, d2) that is defined by the regularity of occurrence. The method according to the invention allows a clear characterization of regular events.

LOCATION-RELATED CHARACTERIZATION OF THE QUALITY OF AN ELONGATED TEXTILE TEST MATERIAL
The invention relates to a method for rating the quality of individual sections of an elongated textile test material whereby measurement values for at least one property of the test material are detected along the longitudinal direction of the test material. Values of at least two different parameters of the test material are determined from the measurement values. A range of tolerance is predetermined for each of the at least two parameters. Parameter values that lie outside the respective range of tolerance are recorded as outliers together with their position along the longitudinal direction. At least two different axes (41, 48) are provided for the position of the outliers along the longitudinal direction. The outliers (51, 52) relating to the at least two different parameters are graphically represented in the places along the corresponding axis (41, 48) that corresponds to their position.
In a method for comparing the quality of elongate textile samples, values of at least one parameter of a first sample are determined. Densities of events in a field of events (4) are determined from the values of the parameter of the first sample and from the spread of said values in the longitudinal direction. A first density line (51, 51') that essentially follows a constant density of the events determined on the first sample is displayed in the field of events (4). A reference density line (56, 56') which follows the same event density as the first density line (51, 51') but relates at least in part to a reference sample that is different from the first sample is displayed in addition to the first density line, thus allowing the shapes of the first density line (51, 51') and the reference density line (56, 56') to be compared. The comparison between the shapes of the density lines (51, 51'; 56, 56') allows the quality of the first sample and the reference sample to be compared.
The method of the invention makes it possible to compare the quality of elongate textile samples (A-D). Measured values of at least one property of the samples (A-D) along the longitudinal directions of the samples (A-D) are acquired. Values of at least two parameters (p-r) of the samples (A-D) are determined from the measured values. For each of the samples (A-D), a quality index is calculated from the values of the at least two parameters. The quality indexes calculated for the at least two samples are represented in a table (4), for example. Such a representation allows the quality of the elongate textile samples (A-D) to be compared in a simple manner.
The method according to the invention is used for rating a presumed cleaning process of an elongated textile test material. Values of a parameter of the test material are determined. An event field (4) is provided, in which the determined parameter values and their extensions in the longitudinal direction can be input as the events (51-53). A density function which depends on the parameters and the extensions in the longitudinal direction is determined. Based on the density function, an alleged cleaning curve (70, 70') is determined in the event field (4) as the separating line between a first half-plane (71, 71') in which almost all events (51, 52) lie and a second half-plane (72, 72') in which practically no events lie. A cleaning index which depends on the density function in a surrounding of the alleged cleaning curve (70, 70') is calculated and output. Said cleaning index rates the effectiveness of the presumed cleaning process.

The invention relates to a disc-type yarn tensioner (1) having a pneumatic cleaning device (2) permanently assigned thereto. The disc-type yarn tensioner (1) has a spindle (13), on which two brake plates (11, 12) are rotatably mounted each by means of a rotary bearing, said disc-type yarn tensioner further having a pressure mechanism (14) for impinging the brake plates (11, 12) with axial compressive forces that press said brake plates (11, 12) against one another. The pneumatic cleaning device (2) has at least one nozzle (21, 22), the flow axis of which is directed from outside substantially towards one of the rotary bearings. The stream of compressed air emerging from the nozzle (21, 22) cleans the disc-type yarn tensioner (1). This ensures that the rotary bearings of the brake plates (11, 12) become soiled to a lesser degree and the rotational movement of the brake plates (11, 12) is braked with the predetermined braking force.
The invention relates to a measuring head (1) for testing yarn (9), said device comprising a measuring slot (3) for receiving the yarn (9) and a first yarn guiding element (41) for guiding the yarn (9) through the measuring slot (3). The measuring head further comprises at least one second yarn guiding element (42) for guiding the yarn (9) outside the measuring slot (3). The yarn path outside the measuring slot (3) is used whenever a zero point balancing and/or an adjustment of the measuring head (1) has to be carried out. A measuring head (1) designed in this manner is particularly suitable for use in classifying yarn defects in the textile laboratory.

A fiber testing instrument has a fiber loading station that is sized to accommodate a fiber sample (26) within a desired size range, a fiber transport device for conveying the fiber sample (26) from the fiber loading station, and a micronaire chamber (34) for receiving the conveyed fiber sample (26). The micronaire chamber (34) is sized to test any fiber sample (26) within the desired size range. Thus, the number of fiber samples that need to be taken for liber testing is reduced.
The fiber sample conditioning system (10) has a comb (22) for engaging and retaining fibers to form a beard (26), and at least two rotating brushes (24) for brushing the fibers simultaneously from opposite sides of the beard (26) in a direction along the fibers away from the comb (22).
A yarn sensor (5) is assigned to a loom (1). The yarn sensor (5) comprises a measuring region (51) for measuring values of at least one parameter of a weft thread (91) to be inserted. An apparatus (10) is provided for removing the weft thread (91) from the measuring region (51) and for reinserting the weft thread (91) into the measuring region (51). The yarn sensor (5) can be balanced to null or adjusted without the weft thread (91) as a result of the invention.
