Abstract (en)
[origin: US5088755A] This snow ski, the sides of which have an inclination which is variable in relation to the plane of the sole of the ski, at different points along its length, and are constituted by curved convex or concave lines, in which the profiles of the sides are of variable curvature according to the cross-section in question of the ski. A procedure for manufacturing this ski consists, starting from a rough ski, in carrying out the machining of the lateral parts of the ski with the aid of a rotary tool with an axis perpendicular to the plane of the upper surface of the ski, the active surface of which is generated by a continuous monotonic curve, by carrying out a relative movement of the tool and of the ski simultaneously, in the direction of the length of the ski, in the direction of the width of the ski and in a direction perpendicular to the plane of the upper surface of the ski.
