Method for removal of material residues from rolls with a material carrying core
The present invention concerns a method for removal of material residues, particularly tissue or similar porous, non-self-supporting materials, from a material-carrying core, which often has relatively large dimensions, e.g. a diameter of approx. 300 mm and a length of approx. 2540 mm, and thereby allow re-use of the core in the same way as new and unused cores a number of times for winding non-self-supporting or porous material, particularly tissue, wherein a cut section is made in the envelope surface of the roll having the material-carrying core from one end or end portion of the roll to the other end or end portion of the roll by means of a driven rotary knife, which is connected to a motor for rotation of the same.

A device for processing cores with a view to restoring same for reuse as good as new and unused cores a number of times for handling and carrying of different types of material webs, includes a number of processing units being arranged to act on the core for removal of material residues and possible other residues in the form of adhesive. The processing surface of the processing units is adapted and/or arranged to adapt itself to the surface of the core on at least the processing thereof under the exercise of a compression pressure between the core and the processing units.
The present invention concerns a method for removal of material residues, particularly tissue or similar porous, non- self-supporting materials, from a material-carrying core, which often has relatively large dimensions, e.g. a diameter of approx. 300 mm and a length of approx. 2540 mm, and thereby allow re-use of the core in the same way as new and unused cores a number of times for winding non-self-supporting or porous material, particularly tissue, wherein a cut section is made in the envelope surface of the roll having the material- carrying core from one end or end portion of the roll to the other end or end portion of the roll by means of a driven rotary knife, which is connected to a motor for rotation of the same.
The present invention concerns a method for preparation of cores primarily for non-self-supporting materials, particularly tissue and the like, after removal of material residues and glue residues for allowing re-use of the cores in the same way as new and unused cores a number of times, wherein the ends of an essentially empty core are cut off while retaining the overall length of the core, wherein at least one end of the empty and end-cut core is prepared for joining with a lengthening core prepared for joining for restoration of the core to the original length and for positioning the joint or splice between the core and the lengthening core as near the end of the core joined with the lengthening core as possible, wherein the end of the lengthening core is machined to conical shape, and wherein the clean cut core end is machined to the corresponding conical shape to fit on or in the lengthening core.

Method and device for stripping of wrapping material
A method and device of stripping of wrapping material including a tool having a first tool portion, a second tool portion, and a third tool portion comprising ends and a casing on substantially cylindrical rolls of paper and the like, in which the end of the wrapping material is opened by engagement by means of a first tool portion from some position on the end surface for processing the end wrapping material by cutting, slicing, and/or sawing of the end wrapping material in a direction out towards the periphery of the end where the end connects to the casing, the end being separated from the casing by means of the first tool portion or a second tool portion by cutting, slicing, sawing during rotation of the roll and/or displacement of the first tool portion or the second tool portion around the periphery of the end.
A method (and device) of removing material residues, from cores to make possible reuse of them in the same manner as new and unused cores a number of times wherein cores with material residues in the form of a number of material turns are processed using a mechanism for lifting and tearing the material residues for subsequent simple removal thereof, the mechanism for lifting and tearing of the material residues is displaced along the core and the mechanism for lifting and tearing of the material residues is displaced from a position in on the core out towards and past the ends of the core.
The present invention relates to a method of stripping of wrapping material comprising, for example, ends and a casing on substantially cylindrical rolls of paper and the like, in which the end of the wrapping material is opened by engagement by means of a first tool from some position on the end surface for processing the end wrapping material by cutting, slicing, sawing and/or other processing of the end wrapping material in a direction out towards the periphery of the end where the end connects to the casing, the end being separated from the casing by means of the first tool or a second tool by cutting, slicing, sawing and/or other processing during rotation of the roll and/or displacement of the first tool or the second tool round about the periphery of the end, and a device for carrying the method into effect.
The present invention relates to a device for handling a number of sleeves (1, 2, 3), preferably paperboard sleeves, before, during and after rolling up of a paper web on each one thereof, in which a body (4) of a length substantially corresponding to the total length or width of the sleeves (1, 2, 3) is inserted in the sleeves (1, 2, 3) and is expandable for pressing the circumferential surface or wall of the body (4) wholly or partly against the inside of the sleeves (1, 2, 3) and thereafter for holding together the sleeves (1, 2, 3) before and during rolling up of the paper webs on the sleeves (1, 2, 3) and the paper rolls thus realised thereon, the body (4) being hose-shaped cylindrical, the ends of the hose-shaped cylindrical body (4) being sealed with an air seal and at least one end being provided with a valve (5) for supplying a medium for expansion of the body (4).
The present invention relates to a device for handling a number of sleeves, preferably paper sleeves, before, during and after rolling up of a paper web each thereon, at least one insert sleeve bent from a rigid material web and having a length substantially corresponding to the total length of the rolls being inserted in the rolls for simultaneous handling thereof, wherein the insert sleeve is polygonal, e.g. triangular, rectangular, etc.
