Definitions

  • the invention relates to a sleeve as a winding core for extremely thin thread-like winding material, in particular glass fibers with a thickness of a few micrometers; with several mutually bonded layers of helically wound webs, each made of a single material and containing fibers.
  • Winding cores for extremely thin glass fibers emerging from nozzles are known in the form of paper tubes with several mutually bonded layers of helically wound webs of so-called kraft paper and are almost exclusively in use.
  • These so-called cuffs which can be pulled up with a circumferential speed of up to 100 mls, and which can be folded flat by double folding along diametrical surface lines of the circular sleeve cylinder, are removed from the tension dome under finger pressure, transversely to that of, by removing the glass laser coil sitting on the paper sleeve the plane defined by the fold lines, onto the center line of one sleeve half (between the two fold lines) first in the form of a kidney and then by bending the two sleeve folds together around the center line parallel to the sleeve axis of the other sleeve half and removing them from the inside of the wrap, after which they bend open again after being bent back and unfolded a winding dome can be tensioned.
  • the invention is therefore based on the object to provide a sleeve as a winding core for extremely thin thread-like winding material such as glass fibers, which preserves the advantages of the sleeve made of kraft paper and at the same time avoids the disadvantages of such a sleeve, that is to say easily foldable and bendable, externally is embossable, heat-resistant, heat-resistant, wet and tear-resistant and can be reused at least as often until the outside of the sleeve would have to be cleaned because of the contamination from the size.
  • each web consists of nonwoven fabric, with each web predominantly comprising chemical fibers which are bound by a synthetic agent; or by the fact that part of the webs are made of nonwoven and the rest of the webs are made of plastic paper, possibly synthetic paper, whereby in each web there are mainly synthetic fibers as fibers, which are bound by a synthetic agent Contrary to ordinary paper made from natural fibers understood an artificial paper that also contains such fibers, but mainly consists of chemical lasers, which have replaced all natural fibers in so-called synthetic paper.
  • the bulk density (according to DIN 53 105) of the synthetic paper or, in the borderline case of the synthetic paper is more than 0.35 glcm 3 , below which there is a nonwoven if the weight fraction of fibers is over 30%
  • the outer layer is provided with adhesive marks which are arranged along the lines following the course of the web forming the outer layer.
  • adhesive marks it can be, for example, those which, as in the exemplary embodiment, were produced by means of a knurled wheel having holes-like depressions on the circumference.
  • a total of four identical inner or middle layers of nonwoven web, the web edges of which adjoin one another without overlap, are followed by a layer made of a different nonwoven fabric which is firmer due to the shape of the outer knobs and thinner because of the overlapping of their web edges, since this is mainly physically is chemically stressed.
  • a sleeve which, apart from the synthetic adhesive used for the ply bond, consists exclusively of nonwovens, which contain fibers made of aramid, polyester, polyamide and cellulose and which can contain, as binders, thermally crosslinkable aqueous dispersions of copolymers based on acrylate. Fibers of 1.5 to 3.5 dtex were used in the nonwoven production.
  • a sleeve according to the invention contains plastic paper, then this should consist of a mixture of slim cellulose fibers with polyamide fibers and of a binder from the class of acrylic acid ester copolymers.
