Abstract: The problem in previously known stay log-type veneer slicers in which a large block of wood is directed in an eccentrically rotating manner past a knife consists of the fact that a remaining block that cannot be sliced has to be removed by hand from a girder structure on which the block is mounted. Hence, the downtime for removing the remaining block and mounting a new block of wood is relatively long. The aim of the invention is therefore to create a stay log-type veneer slicer that has a reduced downtime. Said aim is achieved by disposing means for discarding the block of wood (16) and a device for automatically conveying away the discarded block of wood on the girder structure (12).

Abstract: A veneer lathe is provided with back-up rolls modified to include serrating knives to effect cutting a log longitudinally at predetermined circumferentially spaced apart intervals to define the width of wood strands, and also to include scribing cutters to effect cutting a log circumferentially at longitudinally spaced apart intervals to define the length of wood strands, whereby when the log is rotated past the peeler knife of the lathe, the thickness of wood peeled from the log breaks apart into a multiplicity of vertical grain strands of predetermined length, width and thickness.

Abstract: A veneer cutting station (10) for a wood log (12) comprises a veneer cutting machine (11) producing a continuous sheet of rotary-cut veneer sent to transverse cutting means and at least one incising blade (23) arranged for cutting longitudinally the veneer sheet in a predetermined position of its width and thus form parallel strips of veneer. Downstream of the veneer cutting machine (11) are located deflecting means (14) identifying running tables (27) for strips of veneer each towards one of a plurality of superimposed paths (15,16,20,21) and there being along each path (15,16,20,21) a cutter (18,19) for transverse cutting of the veneer.

Abstract: A substantially uncurved and unwaved plywood includes at least one pair of veneers located symmetrically with respect to a middle of a thickness of the plywood and having unstraight grains which coincide with each other.A method for producing a substantially uncurved and unwaved plywood comprises locating at least one pair of veneers with identical unstraight grains in a pair of positions symmetrical with respect to a middle of a thickness of a plywood to be produced, in such a manner than the grains of the veneers coincide with each other.

Abstract: Disclosed is an apparatus for cutting elongated tubular material into short individual sections. The apparatus comprises a plurality of circular knives fixedly mounted in spaced relationship to each other along the axis of a non-rotating shaft. Rotatable spacing discs having a diameter slightly greater than the diameter of the knives are mounted one on each end of the knife-carrying shaft and are adapted to engage the bare end portions of a rotatable mandrel having a tube to be cut thereon when the knives are moved into cutting engagement with the tube. The rotatable spacing discs riding on the rotatable tube-carrying mandrel prevent the knives from cutting completely through the tube wall and make possible the retention of very thin, frangible, residual tube wall sections of precise constant thickness at the locations of the cuts. This allows the tube to be removed from the mandrel in one piece and then broken later, if desired, into individual short sections by hand or machine.
