Definitions

  • the invention relates to a method for producing a tread component for skis, which has a tread covering, which is produced by extrusion of a strip or plate-shaped material which consists at least predominantly of polyethylene. It also relates to a ski which contains a tread component produced by the method according to the invention.
  • the invention as characterized in claims 1 to 6 is, the object is first to provide a continuous process for producing a tread component with a tread covering made of high molecular weight polyethylene, in which - while maintaining the good properties of the tread covering - the aforementioned disadvantages of the known methods are avoided.
  • the invention finally relates to a ski which has a tread component produced by the method according to the invention.
  • a tread covering based on a high molecular weight polyethylene with an average molecular weight (weight average) of 5. 106 is first produced.
  • a so-called ram extrusion process is preferably used to process polyethylenes of such a high molecular weight.
  • this process has been developed for processing ultra-high molecular thermoplastics, which due to their high molar masses can no longer be plasticized and can therefore no longer be processed by conventional melt extrusion.
  • the strand to be extruded is sintered almost continuously.
  • FIG. 1 now shows a schematic representation of a device for producing a tread component material as an endless strand. It essentially comprises a ram extruder, of which only the nozzle 1 is indicated in the figure, a three-roll calender with the calender rolls 2, 3 and 4 and a supply roll 5 for the material to be laminated.
  • the tape 6 extruded from the polyethylene-lubricant mixture is pulled off the nozzle 1 while still warm and then passes through the gap between the calender rolls 2 and 3, which are kept at temperatures of 80 and 110 ° C. .
  • the tapes thus combined which run over approximately half the circumference of the calender roll 3 and continue to heat up in the process, are now brought to a temperature via the calender roll 4 is held at 100 ° C, on which the polyester fleece 7 is further heated and pressed into the surface of the extruded tape 6 even further.
  • the composite thus formed is pulled off in the direction of arrow 9 from the calender roll and, after cooling, is rolled up as a finished endless tread component material.
  • Fig. 2 shows this tread component material in section.
  • the thickness of the band 6 is denoted by a.
  • the tread component described above has a number of advantages.
  • the hydrophobizing lubricant contained in the tread material of the band 6 reduces the solid friction of ski and snow. Because of the addition of lubricant, it would be difficult to directly glue the tread material of the band 6 to the other ski components during ski manufacture;
  • a decoratively printed film made of thermoplastic material can also be used as the material to be laminated in accordance with another process variant.
  • a film is e.g. B. a film made by a conventional melt extrusion made of polyethylene, which has an average molecular weight (weight average) less than 5. 105. After lamination, the bondability of the free film surface is preferably further improved by flame treatment.
