摘要

Improvements introduced in the portable sander machines, consisting of the establishment of a wide perimeter of the course of the endless belt formed by the sandpaper, by inserting three rollers that are placed two horizontally and the third in high and advanced position, remaining above the front lower roller, the contour describing a triangular figure with very rounded corners, thanks to the diameter of the rollers, within which the cylindrical body of the motor is circumscribed, parallel to the rollers and collaterally linked to the toothed plate of a distributor- reducer.
