Abstract (en)
[origin: WO8804394A1] Method for covering with snow artificial slopes for downhill or cross-country skiing, comprising the formation of an ice layer forming the bottom of the run, the on site production of snow by machining said ice layer by forming chips having a predetermined thickness, the keeping of the thickness of the ice layer forming the run bottom, the maintenance of the desired characteristics and quality of the snow. The machine for implementing such method comprises: a raisable curved blade (5) which is front-mounted for smoothing the snow surface; as a tool, a cylindrical cutter (7) provided with teeth and driven by a hydraulic motor (8) and housed in a casing (10) of which the bottom forms a vault and opens at the rear to deposit snow on the ground; as reconstitution means, a water sprinkling ramp (12) arranged under the vault; a comb (14) provided with tracers (25).
