Abstract
The present invention relates to a device for sanding surfaces of a workpiece, preferably at least portions of which are made of wood, a manufactured wood product, plastic or such like. The present invention further relates to a sanding method and to a sanding machine comprising: a carrier element (11), a plurality of pressure segments (12a, 12b, 12c) which can be actuated, in particular electromagnetically actuated, and which are disposed along the carrier element (11) and are each designed to press a sanding element, especially a sanding belt (21), against a workpiece (1), and at least one sensor (13a, 13b, 13c) for sensing a compressive force applied to a workpiece by one of the pressure segments.
