Abstract (en)
[origin: WO2013180614A1] 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.
