Abstract
A method and apparatus for converting a flitch into sheets of veneer. The method and apparatus include providing a drive mechanism which causes relative motion of a knife in contact with the flitch. The relative motion is relatively slower during one part of the cutting stroke and is relatively faster during another part of the cutting stroke.
Claims14
A veneer slicer including a knife, a flitch table for supporting a flitch, a bell crank having a first arm and a second arm, the second arm having an effective radius, a crankshaft, a connecting rod coupling the first arm to the crankshaft, the second arm coupled to the flitch table, a guide and a follower for following the guide, one of the guide and the follower being movable with the flitch table and the other of the guide and the follower being stationary, the guide including one of an arcuate track and a slide for following the track and the follower including the other of the arcuate track and the slide for following the track, the track having a radius of curvature equal to the effective radius of the second arm, the bell crank, connecting rod, crankshaft, guide and follower reciprocating the flitch table such that the flitch is intermittently drawn across the knife to slice veneer from the flitch.
A method of converting a flitch into sheets of veneer, the method including providing a bell crank having a first arm and a second arm having an effective radius, providing a crankshaft, coupling the first arm to the crankshaft, and coupling the second arm to a flitch table against which the flitch is mounted, rotation of the crankshaft with the flitch in contact with a knife causing sheets of veneer to be cut from the flitch, providing a guide and a follower for following the guide, one of the guide and follower being movable with the flitch table and the other of the guide and follower being stationary, providing a guide and a follower for following the guide including providing an arcuate track and a slide for following the track, the track having the same radius of curvature as the effective radius of the second arm.
