发明名称 ARTIFICIAL SKI SLOPE
摘要 An artificial ski slope has two parallel roller paths arranged side by side, a plurality of axes (4) arranged in a supporting frame and rollers (5, 6) rotating about the axes (4). At least two truncated conical rollers (5) and at least one cylindrical roller (6) arranged between the former rotate about the axes (4). The diameter of the cylindrical roller (6) is equal to the minimum diameter of the truncated conical rollers (5) and the ends of the latter with the smaller diameter face the cylindrical rollers (6).
