Abstract
A veneer reinforcing unit is provided. The unit comprises a first cutter which functions as a cutter for trimming a veneer sheet and a second cutter which extends from one or both sides of the blade of said first cutter. During a trimming action of the first cutter, the second cutter cuts in the veneer sheet at its butt ends newly formed by the first cutter. The thus obtained veneer sheet is ready for any reinforcing step. However, if the first and second cutters are additionally provided with a hole to pay out a cord therethrough, the cut formed in the butt end of the veneer sheet firmly hold the cord since the veneer sheet has a tendency to close the cut after the passage of the second cutter, providing a reinforced veneer sheet.
Claims31
A veneer reinforcing unit comprising a first cutter having a cutting edge thereon;
- a second cutter provided on at least one side of said first cutter and having thereon a cutting edge extending perpendicularly from said first cutter and oriented substantially in a same cutting direction as the edge of the first cutter, said first cutter extending in a first plane, said second cutter extending in a second plane which intersects the first plane;
- and means on said second cutter defining means for guiding a cord to a downstream side of the second cutter into a cut made by the second cutter.
A veneer reinforcing unit according to any one of the claims from 1 or 2 to 8, wherein said second cutter is fixedly mounted on the first cutter.
A veneer reinforcing unit according to any one of the claims from 1 or 2 to 8 wherein said second cutter is detachably mounted on the first cutter.
A veneer reinforcing unit according to any one of the claims from 1 or 2 to 8, wherein said second cutter is positioned at a centerline portion of the first cutter.
A veneer reinforcing unit according to any one of the claims from 1 or 2 to 8, wherein said second cutter is positioned at a baseline portion of the first cutter.
A veneer reinforcing unit according to any one of the claims from 1 or 2 to 8, wherein said second cutter tapers towards an outer end thereof.
A veneer reinforcing unit according to any one of the claims from 2 to 6, further including a means for supplying an adhesive on the downstream side of the second cutter.
A veneer reinforcing device comprising a pair of drive rolls provided rotatably about axes extending parallelly to each other and facing each other to hold a veneer sheet therebetween and feed the same in a predetermined direction;
- a first cutter having a cutting edge thereon, said edge being set opposite a leading edge of the fed veneer sheet and extending in a plane intersecting the veneer sheet to cut the veneer sheet;
- a second cutter fixed onto at least one side of said first cutter and having a cutting edge extending from said first cutter in a plane in which the fed veneer sheet proceeds, and means on said second cutter defining means for guiding a cord to a downstream side of the second cutter into a cut made by the second cutter.
A veneer reinforcing device used in combination with a veneer lathe comprising a first cutter having a cutting edge thereon and provided in association with a veneer lathe knife;
- a means for mounting said first cutter on a frame which supports the veneer lathe knife, said first cutter radially extending relative to a turned log, said edge being oriented in an opposing relation to the log rotation;
- a second cutter fixed onto at least one side of said first cutter and having a cutting edge extending from said first cutter in an opposing relation to the log rotation;
- and means on said second cutter defining means for guiding a cord to a downstream side of the second cutter into a cut made by the second cutter.
