Abstract: A system for selecting wood veneers on the basis of their size comprises in combination: a cutter, at least a selector apparatus downstream of the cutter composed of a vacuum conveyor, expellers cooperating with the conveyor to separate the veneer from it, sensors for reading the length of the veneer which are disposed upstream of the cutter and which control the coming into operation of the expellers, and a conveyor for taking the veneers to a stacker downstream of the selector apparatus. The expellers consist of a plurality of compressed air nozzles above the feed path of the veneer which are adapted to direct in a controlled manner jets of air against the veneer so as to detach it abruptly from the vacuum conveyor.

Abstract: A log clamping apparatus for use in holding half round or stay logs in a cutting operation. The apparatus comprises a rectangular bar rotatable about a rotational axis parallel to the major axis of the bar. The bar has at least one fixed toothed element and one moveable toothed element extending from one narrow side of the bar. The toothed elements face each other and are adapted to extend into axial grooves in the log. Shafts are connected on opposite wide sides of the bar and are each connected to toothed dogs. The shafts are rotated by drive means to pivot the dogs to further clamp the log.

Abstract: In a vertical type wood shearing machine having a blade holder and bar carrying unit and a substantially vertical support cable, the improvement being at least two wood stock support arms each pivotally mounted at one end thereof to the blade holder and bar carrying unit and pivotable from a support position with the arms extended away from the blade holder and bar carrying unit to a retracted position with the arms folded toward the blade holder and bar carrying unit. A double action hydraulic cylinder is associated with each of the support arms and is pivotally mounted at its one end to the blade holder and bar carrying unit and is pivotally mounted to an intermediate portion if each of said support arms at its other end. Each of the double action hydraulic cylinders are mounted at an angle so as to permit the extension of the support arm into the support position and a retraction of the support arms into a retracted position. The arms may be tapered so as to have a top surface inclined toward the blade holder and bar carrying unit to prevent the wood stock supported thereon from falling off the support arms. The arms in their extended position may further be used to push wood stock against the substantially vertical support table and thus insure the wood stock's close association with the support table.

Abstract: A generally vertical veneer slicing device having a plurality of holding hooks for supporting a wood-stock on a generally vertical supporting table. Each of the respective holding hooks include a pair of complementary adjustable jaw members for gripping the wood-stock therebetween wherein the complementary pairs of jaw members vary in length. The arrangement is such that the holding hooks are rendered selectively operative so that progressively smaller hooks are used for supporting the wood-stock as the wood-stock is reduced in size during a cutting operation with the larger length jaw members being shifted to an inoperative out-of-the way position.
