ABSTRACT:
A veneer clipper is adapted to make successive cuts continuously while a veneer sheet is being moved forward through a nip formed by a pair of constantly rotating anvil rolls disposed with their axes extending in parallel to each other across the direction in which the veneer sheet is fed. The clipper includes a pair of knife blades disposed on the downstream side of the nip, having cutting edges thereof presented along the nip, and adapted to pivot together in alternate directions between two extreme positions where the cutting edges are placed in engagement with the peripheries of the respective anvil rolls. The cutting edges of the knife blades are of substantially the same length and extend obliquely at an angle with respect to an imaginary line parallel to the axes of the anvil rolls. Each of the cutting edges is turnable about an axis of its associated knife blade extending in parallel to the edge, whereby cutting into the veneer sheet by the cutting edge takes place progressively from one end of the edge toward the other end thereof.
