  • Patent number: 9993935
    Abstract: An apparatus for clipping ends of a book of sheets includes a first detector for detecting a first end of the book of sheets, a clipper positioning system and a first clipper including a knife. The clipper positioning system is adapted to automatically position the first clipper to a proposed first clipping position based on the detected first end of the book of sheets. A method of processing a plurality of sheets includes assembling the plurality of sheets into a book of sheets, detecting a first end of the book of sheets to propose a first position for clipping the book of sheets, positioning a first clipper based on the detected first end of the book of sheets, advancing the book of sheets to an infeed conveyor, detecting, the presence of the book of sheets in the infeed conveyor, advancing the book of sheets to the first clipper, clipping the first end of the book of sheets, and advancing the book of sheets from the first clipper.

  • Publication number: 20110180183
    Abstract: A veneer slicer includes a knife, a flitch table for supporting a flitch for movement relative to the knife to slice veneer from the flitch, a flitch table support for movably supporting the flitch table, and at least one of a fluid motor and an electric motor coupled between the flitch table and the flitch table support for moving the flitch table relative to the knife more slowly during one part of the cutting stroke and more rapidly during another part of the cutting stroke.

  • Patent number: 7918253
    Abstract: A method and apparatus for converting a flitch into sheets of veneer. The method and apparatus include providing a drive mechanism which causes relative motion of a knife in contact with the flitch. The relative motion is relatively slower during one part of the cutting stroke and is relatively faster during another part of the cutting stroke.

  • Publication number: 20080213532
    Abstract: A process for the manufacture of veneer and a decorative surface veneer that comprises gluing board-like, plane pieces of wood together with an adhesive to form a beam-like block of wood. The humidity content of the beam-like block of wood is increased. Veneer is cut from the beam-like block of wood and dried until the humidity content is below a fiber saturation point. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
