Patent

CA 2219720

The present invention includes apparatus for retaining a tapered flitch (13) having a generally semi-cylindrical veneer-producing zone (21), on a staylog (10) for movement past a veneer-slicing knife, wherein the tapered flitch (13) includes an axis of rotation. The apparatus comprises stationary dogs (54) coupled to the staylog for engaging the flitch (13) and movable pins (56) for moving the flitch into engagement with the stationary dogs (54) to hold the flitch (13) on the staylog (10). The flitch (13) is held on the staylag (10) so that the axis of rotation of the veneer-producing zone (21) is in a parallel relation with the veneer-slicing knife in order to minimize the amount of waste veneer taken from the veneer-producing zone (21).

L'invention concerne un dispositif destiné à retenir une bille conique (13) possédant une zone (21) de production de placage généralement semi-cylindrique, sur un porte-grume (10), afin qu'il se déplace devant une lame de trancheuse, ladite bille conique (13) comportant un axe de rotation. Ce dispositif comprend des griffes fixes (54) accouplées au porte-grume, de façon à saisir la bille (13), ainsi que des broches mobiles (56) servant à déplacer la bille, afin de la faire venir en contact avec les griffes fixes (54) et de maintenir ladite bille (13) sur le porte-grume (10). La bille (13) est maintenue sur le porte-grume (10), de sorte que l'axe de rotation de la zone (21) de production de placage soit parallèle à la lame de trancheuse, ce qui permet de limiter au maximum la quantité de déchets de placage provenant de la zone (21) de production de placage.
