<p>The sanding unit (10) has hinged pins (5,6) that are provided in one-third points between ends of coupling linkage (4) by three compression springs (14) of equal spring force. The sanding unit has an actuator for actuating the coupling linkage to move along the sanding constraint paths (7,8) which are located on the straight line perpendicular to the feeding direction of a workpiece (11) to be sanded.</p> |
