Definitions

  • the invention relates to a method for winding a material web according to the preamble of claim 1.
  • the present invention is based on the object in a method of the type mentioned to set the adhesion between the material web and the winding core so that it generates during winding during the first one to two complete revolutions of the winding core sufficient adhesive force between the material web and lateral surface.
  • the adhesive force should drop sharply in a relatively short time, so that the material web unwinds easily from the core during subsequent processing.
  • the use of a gel greatly reduces the mobility of the water bound in it. This effect leads to the formation of a stress in the interface between the gel and the material web or the lateral surface of the winding core and thus to an instantaneous adhesion between the material web and the lateral surface.
  • the migration of the water from the gel into the winding core or into the material web begins and the adhesive force between the material web and the lateral surface decreases continuously.
  • At least one region of the winding core which forms the lateral surface preferably consists of cardboard or paper.
  • a hollow cylinder made of cardboard has proven.
  • the material web consists for example of a film of plastic, metal, paper or of a multilayer film of at least two layers of said materials.
  • the chemical composition of the gelling agent is of minor importance for the process according to the invention.
  • the sole purpose of the gel is to reduce the mobility of the water during the first phase of winding a web.
  • gel formers for example, fumed silica, sodium silicate and boric acid, gelatin, celluloses such as pure cellulose powder, hydroxyethyl cellulose, hydroxypropyl cellulose, etc. and starches such as corn starch, rice starch, potato starch or wheat starch can be used.
  • a gel that is as firm as possible ie a gel whose water content is smaller than its maximum possible water content, is used.
  • the webs of material wound with the method according to the invention can be automatically and uninterruptedly hung together in a continuous further processing.
  • a particular area of application of the method according to the invention relates to the winding up of material webs which are cut from a material strip in a cutting device.
  • an end 11 of a material web 10 is fastened by means of an adhesive tape 16 to the cylindrical jacket surface 14 of a winding core 12 with a cylindrical or rotational axis s.
  • the adhesive force of the adhesive tape 16 is dependent on its length.
  • the adhesive force to the lateral surface 14 of the winding core 12 may be so large that the material web does not readily dissolve during subsequent unwinding of the lateral surface, which can lead to problems especially in Autosplicing machines.
  • a gel 18 is applied to the water-based on the winding core 12 side facing the web 10 and the gel with the 18th provided end 11 is applied to the cylindrical surface 14 of the winding core 12.
  • the winding core 12 is, for example, a hollow cylinder made of cardboard and the material web is e.g. an 80 ⁇ m thick packaging film made of an aluminum / plastic composite material.
  • the water-based gel contains, for example, a mixture of sodium silicate and boric acid as gelling agent.
  • the resulting adhesion between web 10 and winding core 12 is sufficiently high that the web is taken during the first revolution of the winding core 12 of this.
  • the water migrates completely over time in the winding core 12 and the adhesive force decreases continuously.
  • the adhesive force is practically zero and the end 11 of the material web 10 firmly adhering during winding is easily detached from the lateral surface 14 of the winding core 12.
