Abstract
Sanding device, perfected; that with an endless abrasive belt or sandpaper, lying between three rollers, one tensor and optionally motor, while the other two rollers are rotating. Free and are arranged in the same parallel plane with respect to a conveyor belt for the parts to be treated, and of the type where this assembly is able to approximate or move away the section of working sanding with respect to the faces or edges of the piece of material that is to be treated. Try essentially it is characterized in that between the pair of rollers parallel to the working area has been removably installed at least one other roller that rotates in loco on its own axis by direct transmission, which is exerted by the abrasive band itself, determining the diametral dimensioning of this roller an arrow for the operative section of the sandpaper that fixes a zone of contact with the piece in treatment.
