Abstract
A nosebar is supported by supports arranged along the longitudinal direction, and the supports are assembled to fixtures to swing independently of each other in a direction away from a log according to the reaction force of the pressing force acting on the supports. Thus, when a knife peels a knot part of the log or a fragment of the log enters a cutting edge, the portion of the nosebar pressing the knot part or corresponding to the location where the fragment enters the cutting edge is greatly deformed, while the deformation of the nosebar in the other portions is kept small. A corner of the nosebar is prevented from contacting the peeled portion of the raw wood and generating a gap when the nosebar is bent and deformed.
Claims20
A knife carriage in which a long knife and at least one long, unitary pressure bar are mounted, the knife being disposed to face wood including a log for peeling a veneer from the wood, the pressure bar configured to press a peeled portion of the veneer from a side opposite to the side where the knife is disposed with respect to the peeled portion, the knife carriage comprising:
- a knife mount extending in a longitudinal direction of the knife for receiving the knife;
- a pressure bar mount disposed above the knife and extending in the longitudinal direction of the knife for receiving the pressure bar;
- and
- a support member disposed between the pressure bar and the pressure bar mount for supporting the pressure bar,
- the support member including at least one fixture fixed to the pressure bar mount, a first support supported by the fixture so as to support one end of the pressure bar in a longitudinal direction of the pressure bar, and a second support supported by the fixture in a position separated from the first support in an extending direction of the pressure bar so as to support the other end of the pressure bar in the longitudinal direction, and
- the first and second supports being supported by the fixture to be movable independently of each other in a direction away from the wood according to the magnitude of a reaction force of a pressing force of the pressure bar against the peeled portion, the reaction force acting on the first and second supports via the pressure bar.
