PCT No. PCT/AT92/00121 Sec. 371 Date May 19, 1993 Sec. 102(e) Date May 19, 1993 PCT Filed Sep. 25, 1992 PCT Pub. No. WO93/05853 PCT Pub. Date Apr. 1, 1993.The invention concerns a process for manufacturing a strip of ski-coating material made of polyethylene of ultra high molecular weight, wherein a ski-coating strip material 4 manufactured to a thickness of 0.5 to 1.5 mm by a screw extruder, a ram extruder or press sintering with subsequent peeling is made to pass continuously first through a heating zone 1 in which it is heated to temperature above 140 DEG C. and then through a cooling zone consisting of two sizing plates 2, 2' in which it is cooled to a temperature equal to or lower than ambient. This process produces a ski coating of which the crystalline proportion can be adjusted within a range of 25 and 60%, as a result of which improved gliding by the ski coating on snow and improved wax acceptance is assured in comparison with the known methods.
