Title:
A KNIFE CARRIAGE, A ROTARY VENEER LATHE HAVING THE SAME, AND A VENEER SLICER HAVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2021/020001
Kind Code:
A1
Abstract:
A nosebar 20 is supported by supports 34 arranged along the longitudinal direction, and the supports 34 are assembled to fixtures 32 to swing independently of each other in a direction away from a log PW according to the reaction force of the pressing force acting on the supports 34. Thus, when a knife Kn peels a knot part Sp of the log PW or a fragment of the log PW enters a cutting edge, the portion of the nosebar 20 pressing the knot part Sp or corresponding to the location where the fragment enters the cutting edge is greatly deformed, while the deformation (the amount of movement) of the nosebar 20 in the other portions is kept small. A corner of the nosebar 20 is prevented from contacting the peeled portion 90 of the raw wood PW and generating a gap when the nosebar 20 is bent and deformed.
