Abstract (en)
[origin: US4431209A] A ski has an elongated body part, a polyethylene bottom layer arranged on the body part, and a roughening provided on a sliding surface of the bottom layer over a supporting length of the ski and including a plurality of projections each formed as an elongated tooth from polyethylene of the bottom layer and inclined in its entirety toward the rear end of the body part, wherein the teeth are arranged with a density of between 1000 and 4000 teeth per cm2. The inventive ski is manufactured by dry grinding of the sliding surface of the polyethylene bottom layer with a relatively high efficiency.
