<p>In automatic equipment for sanding the rounded corners of boards, use is made of a sanding unit (26) with an abrasive belt (7) looped around at least two rollers (2, 4) and urged against the rounded corner (50) of a board (1) by a pressure pad (8) positioned alongside one of the rollers; the system also makes use of a sensor (13) which first ensures that the feed speed of the board and the traverse speed of the sanding unit are matched, and then triggers rotation of the entire unit (26) about the rounded corner of the board.</p> |
