Abstract: An apparatus for machining a ski includes a support for the ski and a device for conveying the ski in the longitudinal direction of the ski, along the support. The support is assigned a device for machining the side walls of the ski using at least one cutting tool, which is arranged on a tool carrier, the latter being guided adjustably in a direction transverse to the conveying direction and parallel to the support, and which, with the aid of a resilient actuator for the tool carrier, can be positioned, with resilient prestressing, against that side wall of the ski being conveyed along the support which is to be machined.
