    Abstract: The invention relates to a method for separating small pieces from blanks of material by using a device comprising a plurality of cutting elements, with short cutting edges as compared with the blank, said cutting elements being so arranged on the face of a rotating cutting element holding means with their edges pointing essentially in the direction of rotation, that always a plurality of said edges are in holding engagement with the blank during the rotation of said holding means when said blank is moved along a path intersecting said face. The feeding path has a projection, the direction of which is essentially parallel to the direction of the tangents of the orbits of the cutting elements in the place where said path intersects said face. When applicated to a method of chipping timber the invention has the consequence that an elongated chip blank is cut from a sloping end face of the log by each cutting element, the width of said chip blank as determined by the length of said cutting edge being the same as the width of a separate chip, the length of each chip being determined by the angle between the direction of the fibers in the blank and the direction of the thickness of the blank. The invention also relates to a device for separating small pieces from a blank of material, particularly a chipping machine for chipping timber to chips, said device comprising a plurality of cutting elements, with short cutting edges as compared with at least the next smallest dimension of the blank, said cutting elements being so arranged on the face of a rotating cutting element holding means at different distances from the axis of rotation of said holding means and with the edges pointing essentially in a direction of rotation, that always a plurality of said edges are in holding engagement with the blank during the rotation of said holding means when said blank is moved along a path intersecting said face. The inclination of the back of the cutting element, i.e. the surface of the cutting elements directed towards the blank and the abutting the cutting edge, towards a plane including the rotational path of the cutting element is different between the cutting elements in such a manner that it increases with a reduced spacing between the cutting element and the axis of rotation of the holding means. In another device for carrying out the method the cutting elements are arranged on a cylinder and the feeding path for the blank to be separated extends at a right angle to the cylinder axis.

    Abstract: Pieces of scrap veneer are fed by a conveyor belt across an anvil and into a rotating chipper head. The pieces are held against the anvil by a plurality of laterally spaced pivotal fingers having wide flat tip portions overlying the anvil. An inflatable air bag extends over the fingers and underneath a pivotally supported adjustable weight member for resiliently urging the finger tip portions against the anvil. When the tip portion of one or more of the fingers rises to a predetermined height, the weight member is lifted with the finger so that the holddown force on the veneer does not exceed a predetermined maximum limit.

    Abstract: Method and apparatus for breaking down logs in a continuous or substantially continuous manner into useful products, such as pulp chips, boards and/or timbers. The method entails conveying each log past a set of cutting elements arranged to cut one or two flat horizontal surfaces thereon. It preferably includes placing the cut log with the flat surface or surfaces on a suitable conveyor, and moving the log past a second set of cutting elements arranged to repeat the original cutting operation. The method preferably includes removing slab areas of the logs as pulp chips while simultaneously removing boards therefrom during formation of the flat areas at each set of cutting elements. The apparatus is designed to carry out part or all of said method. The apparatus grips each log from below and moves it horizontally past said first set of cutting elements arranged above the log, and it preferably includes a second stage wherein the log after being turned over is transported past said second set of cutting elements arranged above the turned log.
