ABSTRACT:
A process and a device for the continuous chipping of timbers of different length. To increase the chipping performance, in the execution of the sawing cut or directly thereafter, at least one supporting element for supporting the leading end face of a long timber pack and the posterior end face of a short timber pack is directed into the sawing plane. Directly adjoining the short timber pack, a just sawn-off short timber pack, together with the supporting element enclosed between them, is conveyed forward by one advancement cycle in the same direction. The supporting element, following the conclusion of the advancement cycle, is conveyed back into the directing-in area of the sawing plane, and each short timber pack is supportingly transported, free from any structural distortion, up to the chipping tool.
