Pivotal Wood Bending Form Patents (Class 144/267)
  • Patent number: 10773471
    Abstract: A composite manufacturing system has a tool having a substantially planar first portion and a substantially planar second portion, a first carriage configured to carry a first roller that is configured to selectively apply pressure to the first portion, a second carriage configured to carry a second roller that is configured to selectively apply pressure to the second portion, and the first carriage and the second carriage are movable relative to the tool.

  • Patent number: 7448608
    Abstract: The invention relates to a foldable frame (1) for oscillating saws or the like with an elongated support body (2), to which the oscillating saw is mountable, and to which, at each one of its two respective ends, are connected two legs (6,7), the latter being swivelable from a storage configuration in which they extend essentially parallel to the support body (2) to an operative configuration in which they extend essentially perpendicular from the support body (2). In order to improve the usefulness of the above-described foldable frame, it is proposed that the support body (2) be configured as two support body sections (3, 4), which are connected to one another by a hinge (5), which in the storage configuration lie parallel to each other, and which by swivelling movement through 180° can be brought into the operative configuration.

  • Patent number: 6971423
    Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths.

  • Patent number: 5203948
    Abstract: An apparatus and method is disclosed for the bending and pressing of laminations into 2-dimensional or 3-dimensional curves. The apparatus includes a pair of spaced apart rotatable clamps for the clamping of the laminations at spaced apart locations. At least one of the clamps is movable towards the other clamp. Counterclockwise rotation of the clamps bends the laminations held by the clamps. A clamping force of at least one of the clamps is controllable so that the laminations may be bent while a mutual sliding movement of the laminations in at least one clamp is permitted. The laminations are bent to a radius larger than a desired radius. At this point, the clamping pressure is increased to prevent the mutual sliding movement so that upon further bending of the laminations, the outer laminations are pressed against the inner laminations at a substantially evenly distributed force along the bent section of the laminations.
