  • Patent number: 5983967
    Abstract: The invention concerns a tool head for shaping machine designed to machine the side segments of tree trunks. The tool head has a rotationally driven main body (1) with several groups of chipper blades (2, 3) round its circumference. The front chipper blade (2) in each group and a front-mounted finishing tool, e.g. a segment (4) of a circular-saw blade, are mounted on a common tool carrier (5). The tool carrier (5) is detachably attached to the tool-head main body (1) and is held in place by clamps (16). If, as a result of wear, it becomes necessary to replace a tool, the tool carrier is replaced after the clamp (16) has been loosened.

  • Patent number: 5400843
    Abstract: Sheets of wood are cut from a timber piece along a guide and against a cung blade. A transverse taper of the wood piece is measured as the wood piece is conveyed. In accordance with changes in the measured transverse taper, the guide or the blade is pivoted about an axis extending perpendicular to the blade edge as the wood piece is being conveyed. Also, the longitudinal taper of the wood piece can be measured as the wood piece is conveyed. In accordance with the changes in the measured longitudinal taper, the distance between the blade edge and the wood guide is varied as the wood piece is conveyed.

  • Patent number: 5291927
    Abstract: An apparatus for truing twisted wooden boards by twisting them in an oppoe direction, comprises an upper set of parallel plates and a lower set of parallel plates. A channel is formed between opposing edges of the upper and lower plates. The upper plates are pivotable about an upper pivot axis, and the lower plates are pivotable about a lower axis. Those axes are oriented transversely relative to a longitudinal axis of the channel and are situated at an inlet end of the channel. A pivoting mechanism causes the plates to be displaced vertically relative to one another to twist the channel about its longitudinal axis.

  • Patent number: 5255725
    Abstract: Wooden boards which are deformably twisted about their longitudinal axes straightened by being passed through a path that is twisted in a direction opposite that of the boards. The degree of twist of the boards is automatically adjusted as a function of the humidity of the boards and possibly also as a function of the temperature of the boards.

  • Patent number: 5123319
    Abstract: A circular saw shaft for cutting wood comprises a motor-driven shaft and a ircular saw blade mounted on the shaft. A support disk is mounted on the shaft in spaced relationship to the saw blade to apply to the wood a supporting force in a direction extending parallel to the axis of rotation of the shaft. The support disk can be fixed to the shaft, or biased along the shaft axis by springs. In lieu of springs, the support disk could be elastically flexible.

  • Patent number: 5069977
    Abstract: A multi-ply solid wood structure, such as a beam, a board or a truss, and a ethod of manufacturing such wood structures are disclosed. The wood structure comprises wood lamellae that are joined together, wherein the wood lamellae are produced by a chipless separation from squared timber using a blade or a knife, and wherein the lamellae have a knife side that was adjacent to the knife during the process of separation and an opposite side that is remote from the knife side. In one embodiment, the wood lamellae are arranged in the multi-ply solid wood structure such that, when viewed from a center plane of the wood structure extending generally in parallel to the external surfaces of the lamellae of the wood structure, the opposite side of each wood lamellae is directed toward the two external surfaces of the wood structure.

  • Patent number: 5052452
    Abstract: A method wherein a length of squared timber can be completely separated i a number of thin boards having a predetermined thickness without an excessively thin or excessively thick unusable residual board being left over is disclosed. The method includes measuring the thickness of the residual squared timber after one or more thin boards have been separated, and feeding the thickness measurement back to the cutting apparatus to adjust the setting of the apparatus. The method is useful on an apparatus that separates a length of squared timber into thin boards without producing chips and without timber loss, and wherein the predetermined board thickness cannot be set exactly because of variations in the property parameters of the wood.

  • Patent number: 5027517
    Abstract: A circular saw head (1) for the cutting of side boards (3) from a log (2), as a circular saw blade (4) mounted on a saw shaft (10) by a support flange (5). Within a rim of saw teeth (13) and radially spaced apart from it a frontal annular support surface (12) is provided, extending axially over the frontal surface (8) of the saw blade (4) and located in the plane of the frontally outer edges (14) of the saw teeth (13). The support surface (12) supports the surface cut on the wood by the saw teeth (13), thereby guiding the wood.

  • Patent number: 4977940
    Abstract: Boards that have been separated by a chipless cutting method using an inced blade, are twisted and, in most instances, this twist has to be corrected before boards that have been produced in this manner can be used. An apparatus in which a plurality of pairs of rollers are arranged in tandem withing a main frame is used to do this. Each pair of rollers can be pivotted about the longitudinal axis of the main frame relative to the proceding pair. This forms a board guide channel that extends in the longitudinal direction of the main frame and which is twisted approximately about the longitudinal axis of the main frame. The boards that are to be straightened pass through the board guide channel and are permanently deformed, which compensates for the twist that originally existed in the board.

  • Patent number: 4960023
    Abstract: A circular cross-cut sawing apparatus comprises two transversely adjustable lides each carrying a plurality of saw blades. The saw blades on each slide can be selectively lowered into the path of oncoming boards. The slides are independently adjustable so that any given board can be cut by blades on both slides.

  • Patent number: 4907632
    Abstract: A tree trunk is fed to a cutting station along a centerline line by a pluity of groups of centering rolls spaced along the centering line. Some rolls are driven to advance the trunks. The groups of rolls are adjustable from a centering mode to a non-centering mode by either retracting the rolls or unloading the rolls. During the advancement of a trunk successively through the roll groups, the groups are successively adjusted between their centering and non-centering modes such that roll groups located to support front and rear ends of the trunk are in their centering modes, while at least one roll group disposed therebetween is in its non-centering mode.
