Abstract: A heavy flywheel disc having a radially spaced apart array of pockets in which are mounted knives. Short logs, which have been de-barked, are fed in with their long axis parallel to the face of the flywheel. A hydraulic ram translates the logs sideways into the plane containing the rotating knives. The use of the hydraulic ram provides for a variable infeed speed to obtain the particular thickness of shavings which provides in the end commercially desirable shavings for use, for example, in horse stables. The knives have notched cutting edges. The notches limit the width of each shaving to create strands which are for example ¾ inches wide. The strands are then chopped in an automated chopping device such as a forage harvester to produce shavings.

Abstract: An apparatus for slicing elongate fibrous material has a slicing device having an axis of rotation about which the slicing device rotates during operation. The slicing device has slicing tools with a blade carrier and a blade unit. The blade units have cutting blade edges that together define a common cutting surface. The elongate fibrous material is fed in slicing cycles in the direction of its longitudinal extension to the blade units. Slicing is carried out parallel to the fiber orientation by realizing a relative movement between the elongate fibrous material and the blade units transverse to the fiber orientation. The slicing tools have an end face with a receptacle extending parallel to the end face. The slicing tools have a cutting element arranged in the receptacle. The cutting element performs a separating cut in a direction transverse to the fiber orientation in the separating plane between two slicing cycles.

Abstract: An automated system and process for managing building materials which requires a minimal amount of manual labor and supervision. The automated system and method are especially suited for precutting lumber used for building trusses and frames having predetermined specifications.

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: The invention relates to an apparatus for producing sideways curved wood wool fibers. The apparatus comprises a flat rotatable disc (2), in the surface of which is provided at least one knife assembly (7) comprising a thickness knife (8) which projects slightly above the surface of the disc (2) and which has a cutting edge extending substantially radially and further comprising width knives (9) positioned as seen in the direction of rotation of said disc (2), ahead of said thickness knife (8) and having a cutting edge extending substantially tangentially. The width knives (9) are positioned in the immediate vicinity of the thickness knife (8), whereas their cutting edge may engage the thickness knife (8). Further the apparatus is provided with at least one feeding device (5) for feeding the disc (2) with wood blocks (6) to be cut up into fibers. Further a run-up guide may be positioned ahead of the width knives.

Abstract: Short metal fibers are directly produced from a work metal block. The product fibers are very thin and short, e.g., 200 .mu.m in diameter and 20 mm in length to the maximum. A bar like or pillar like metal bar is rotated, to which an elastic cutting tool is contacted. The entering width of cutting edge corresponds to length of fiber to be obtained. The tool is effected with fine feed and at the same time positively generated with self excited vibrations. The self excited vibration forcibly separates and divides a thin layer fiber accumulating at the cutting edge of the tool one by one without having connections in length of the fibers to each other. The process produces needle like fibers of microscopic cross sectional area. The thin and short metal fibers are produced in the same number as number of the self excited vibrations, and the fiber is right angled in axis with the cutting direction.

Abstract: A scratcher element in a cutter arrangement of a wood-cutting tool is formed of a rectangular plate and two projections outwardly extended from the side faces of the plate. The scratcher element is inserted in a special slot formed in a supporting strip of the cutter arrangement. These two projections each have a cross-section of the shape of a segment of the circular disc.

Abstract: A holding device for a rotary cutter has a supporting member extending over a greater part of each cutting element and having a web and holding tongues provided with an openings for receiving tightening screws, an abutment surface for abutting the cutting element and determining a projecting length of the latter, a wearing member fixed in the body part for abutment of the rear surface of the cutting element, a locking member for fixing the wearing member, a centrifuging wedge member with a wedge surface pressing the cutting element against the wearing member, wherein the wearing member has a locking groove which is open toward the cutting element and forms the abutment surface and in which the web of the supporting member is received in a form locking manner, and the centrifuging wedge member lies with its wedge surface directly against the front surface of the cutting element.

Abstract: Apparatus for eradicating tree stumps comprising a rotary cylinder or drum having knives or teeth around its periphery. The teeth include both cutter teeth and chipper teeth. The primary purpose of the chipper teeth is to hog out and remove the fibrous wood material. The primary purpose of the cutter teeth is to break up and cut or slit the fibers so that they may be more easily hogged out by the chipper teeth.

Abstract: A woodwool producing machine comprises a cutter wheel which is supported with its axis vertical and which has a frusto-conical rim at its outer periphery. The rim tapers upwardly and has a circumferential array of slots formed in it, a cutter assembly, which comprises a pair of cutters for cutting woodwool strands from timber stock, is mounted in each slot. Several timber feed magazines are positioned at spaced intervals around the circumference of the rim and are adapted to support and locate pieces of timber stock against the outer surface of the rim with their grain generally tangential to the rim. The cutter wheel is driven in operation so that strands of woodwool are cut by the cutters from pieces of timber located against its rim. The woodwool is directed to the interior of the wheel, through the slots, and falls onto a collector.

Abstract: A waferizer having a rotatable cylindrical head from which a plurality of waferizing knives project for slicing wood stock, and rollers mounted on the head which have a plurality of longitudinally extending radially projecting blades for incising the face of the wood stock to a depth equal to the depth of cut of the knives so as to produce wafers of uniform width.

Abstract: The periphery of the chipping drum carries one or more axial rows of individual chipping bits in which the bits of adjacent rows are in staggered relationship if there is more than one row, and further carries an evening knife located in a position trailing the row or rows of individual cutting bits. The individual cutting bits are located with reference to ridges of the circumferentially corrugated drum periphery so that each ridge is disposed substantially centrally of a cutting bit. The anvil is corrugated complementally to the chipping drum periphery and is located so that the cutting edges of individual bits move through notches of the anvil. The evening knife moves close to the projections between the anvil notches.

A second pulp chip forming crosscut saw includes a carrier member supporting a U-shaped tooth having side slitting side plates and a raker top plate which carries on the top thereof a center slitter. Another pulp chip forming crosscut saw includes a solid block, sloping faced raker having a center slitter on the top thereof and mounted by an undercut interlock on a carrier. Another pulp chip forming crosscut saw includes a solid block, a sloping faced raker carrying a center slitter on its top and a pair of side slitters at the sides of the block.
