  • Patent number: 6176282
    Abstract: A pair of centering spindles are disposed away from cutting spindles and movably in the direction of Z or parallel with the axial center line of cutting spindles. A plurality of log center detecting means are disposed along the Z direction in relative to a log chucked by the centering spindles. A pair of holding members are mounted movably in the directions of X, Z, and Y including components orthogonally intersecting the X and Z. By way of controlling means, the centering spindle holding a log is caused to rotate at least one revolution thereby enabling the log center detecting means to determine each position of axial center which is assumed to constitute the axial centers at both end faces of the log, the virtual line passing through every positions of axial centers in Z direction is aligned with the Y, and the holding members are moved in the Z direction to hold the log, after which the chucking of log by the centering spindles are released.

  • Patent number: 5971045
    Abstract: A veneer lathe comprising a knife (2) for peeling a log (1), which is secured rotatably to a knife stock, and a roller bar (3) disposed to press a circumferential surface of the log (1) at an upstream side, in relative to said knife (2), of a rotational direction of the log (1). The roller bar (3) has a diameter of not more than 30 mm, and is provided on the circumferential surface thereof with a large number of projections (5) whose height is not higher than the circumferential surface of the roller bar (3). The roller bar (3) is sustained in a sliding bearing (9) and adapted to receive a rotational force from a driving source. The roller bar (3) functions not only as a pressure bar but also as a power transmitting media to rotate the log (1), thereby preventing the generation of lathe check of veneer to be produced.

  • Patent number: 5967208
    Abstract: An improved apparatus and method for use in the rotary cutting of wood veneer is disclosed. The improved apparatus and method are preferably employed in connection with a conventional lathe having a pressure bar. Such a lathe is of the type that is used to produce wood veneer from a workpiece of wood, such as a log. The improvement is characterized as maintaining a preselected pressure of the pressure bar against the wood, and subsequently adjusting the preselected pressure bar position by using means for doing so, thereby producing wood veneer of uniform thickness and surface quality, independent of variations in wood density and wood hardness, such variations resulting from natural growth conditions and temperature of the wood.

  • Patent number: 5927360
    Abstract: A centerless rotary veneer lathe comprises a slidable backup device which is disposed on the opposite side of a peeler log from a knife carriage of the lathe. The backup device has a pair rotatable rolls located one above the other with the axes thereof extending in parallel to the axis of the log. The paired rolls are disposed such that the axes of such two rolls are spaced at substantially the same distance from an imaginary line extending perpendicularly to the axis of the log and in parallel to the direction in which the backup device is moved. In operation of the veneer lathe with the rolls set in contact with the log periphery, the knife carriage and the backup device are moved synchronously at such a variable controlled rate that causes peeling of veneer with a predetermined thickness.

  • Patent number: 5791388
    Abstract: A method of controlling the feed of the backup rolls of a log backup apparatus for use in a veneer lathe for preventing a log from bowing while veneer is peeled from the log. The method comprises the step of centripetally feeding the backup rolls from a control-start diameter .PHI. at a provisional feed rate f which is higher than a predetermined feed rate F by a feed rate of a pre-selected correction value .alpha. per log rotation. The aforementioned control-start diameter .PHI. is slightly larger than the diameter of the log at which the backup rolls are brought into contact with the log. The method further comprises the steps of stopping the centripetal feeding of the backup rolls at the provisional feed rate f when the bowing is eliminated from the log and thereafter centripetally feeding the backup rolls at the predetermined feed rate F, thereby eliminating the bowing that occurs during the veneer peeling from the log.
