Device for trimming wane-affected planks The device makes it possible to optimize the work of a trimming machine with multiple blades. It comprises, in the plank transfer assembly located upstream of the trimming machine, between the scanner and the trimming-machine entry table, an intermediate preparation table (10) facing which are arranged means of emitting at least two light beams, particularly four laser beams (L1, L2, L3, L4) directed onto a plank (24) stopped on the preparation table (10) and forming marks on this plank. The position of the beams can be modified manually and remotely by an operator to take account of wane zones (25, 26) and defects (27, 28) in the heart of the wood. This corrected position is taken into consideration automatically by the positioning of the blades of the trimming machine accordingly.
Device for trimming wane-affected planks, making it possible to optimize the work of a trimming machine (2) with multiple blades (3), characterized in that it comprises, in its plank-transfer assembly located upstream of the trimming machine (2) and used to feed the latter, more particularly between a scanner (9) and a trimming-machine entry table (13), an intermediate preparation table (10) facing which are arranged means (17) of emitting at least two light beams (L1, L2, L3, L4) directed onto the location of a plank (24) stopped on this preparation table (10), manually remotely controllable means being provided for modifying the position of the light beams (L1, L2, L3, L4), and other means being provided for automatically taking the corrected positions of the light beams (L1, L2, L3, L4) into consideration by positioning the blades (3) of the trimming machine (2) accordingly.
