Abstract (en)
[origin: EP0341236A1] To manufacture a sole member for skis, a strip-shaped material is extruded from polyethylene powder with a mean molar mass (mean weight) in the region between 5.10<5> and 8.10<6>, which is mixed, if appropriate with low-molecular additives, such as oils, paraffins, lubricants, waterproofing agents and the like, using a special extrusion method, e.g. a so-called ram extrusion method. Even before the strip-shaped material is cooled, a flat material, consisting at least mainly of plastic, is laminated onto one of its surface sides, said material being provided on that side, on which it is to be connected to the polyethylene sole material, with a decorative layer, preferably a print which can then be recognised on the sole member through the transparent sole material. This composite material is then cut to the lengths of sole members. The material to be laminated on, which can consist of a nonwoven, e.g. a polyester nonwoven or of a thermoplastic film, such as a melt-extruded polyethylene film, additionally serves as a bonding aid for the sole material. <IMAGE>
