Abstract: The invention relates to a process and apparatus for producing veneer strips of predetermined length, width and thickness from wood. The apparatus has a severing tool for dividing the wood to be machined into boards, a clamp for clamping the boards, and a machining device for machining the clamped boards into veneer strips.

Abstract: A long-timber chipping machine has a timber feed channel for receiving longitudinally arranged timbers, advanced using a timber-advancing device to a vertically movable chipping device positioned at the downstream end of the feed channel. The chipping device has a rotatable cutter ring equipped with chipping cutters on its cylindrical inner wall, which defines a chipping chamber. The chamber is aligned with the downstream end of the feed channel. To improve the chipping, a curved timber-receiving plate projects into the chipping chamber from the downstream end of the feed channel, which also has a matching curved base. The curvature of the plate and the base match the curvature of upper cylindrical inner wall of the cutter ring so that the upper cylindrical inner wall can be lowered closely to the plate, leaving only a very small clearance and exposing all of the timbers to the chipping cutters.

Abstract: A blade mounting for a chipper blade of a wood-chipping machine, the chipper blade having a back and a fore-part, the blade mounting including: a disk coverplate having an inner slope which bears against the back of the chipper blade; a blade holder having at least two grooves which are oriented perpendicular to a longitudinal axis of the blade holder and parallel to a plane of the chipper blade, the blade holder bearing against the fore-part of the chipper blade; adjusting screws located in the grooves in the blade holder; and dogs for underpinning a bottom edge of the chipper blade at at least two locations, the dogs being adjusted by the adjusting screws.

Abstract: A process and a device for the continuous chipping of timbers of different length. To increase the chipping performance, in the execution of the sawing cut or directly thereafter, at least one supporting element for supporting the leading end face of a long timber pack and the posterior end face of a short timber pack is directed into the sawing plane. Directly adjoining the short timber pack, a just sawn-off short timber pack, together with the supporting element enclosed between them, is conveyed forward by one advancement cycle in the same direction. The supporting element, following the conclusion of the advancement cycle, is conveyed back into the directing-in area of the sawing plane, and each short timber pack is supportingly transported, free from any structural distortion, up to the chipping tool.

Abstract: Method for the manufacture of flakes from chips and apparatus for carrying out the method. The worn, in use, blade portions of a strip-steel knife are exchanged continuously or periodically with sharp strip-steel knives during the flake manufacturing operation. The feed of the strip-steel knives is preferably time-dependent and/or dependent on the energy consumption of the apparatus. Disposed longitudinally of the knife-ring are one or several magazines for supplying or/and receiving the strip-steel knives.
