<p>In a sanding machine, a wood panel (2) is moved forward beneath a sanding device (10) having an abrasive belt (11) wound in a ring shape around a tensioning drum (13) and a drive drum (12) defined by a cylindrical sleeve (21) fitted in a rotatory way on a support shaft (16), which has two eccentric ends (18) coaxial to each other, and is moved from a lowered operating position to a raised rest position by means of an actuating device (24) connected to the support shaft (16) so as to allow, in use, the drive drum (12) to move around a longitudinal axis (19) of the two eccentric ends (18) as a function of the profile of the panel (2).</p> |
