ABSTRACT:
In a process of forming a profiled tread surface on a ski, a cutting tool is moved in steps of defined length in the longitudinal direction of the tread surface to be profiled and in steps of defined length transversely to said longitudinal direction. The cutting tool thus moved is used to form said tread surface with individual recesses, which partly overlap and are defined by sawtooth-shaped step ramps extending in said longitudinal direction. Adjacent transverse rows of said recesses overlap preferably by one-half of the length of each of said transverse steps.
