  • Patent number: 4632161
    Abstract: A veneer lathe for peeling a veneer from a log, comprising a knife mounted on a knife frame and adapted to peel said veneer from said log, a plurality of pressure bars retained on a pressure bar frame as disposed parallelly to said knife and spaced in the direction of the line of the blade of said knife, roller discs interposed one each between said plurality of pressure bars, retained on said pressure bar frame through the medium of rotary shafts, and rotated at a peripheral speed greater than the peripheral speed of said log, a guide face forming the passage of said veneer from the vicinity of said knife through said roller discs, a plurality of pressure rollers disposed on the lower side of said guide face and pressed displaceably in the direction of the axial line of said roller discs, and a guide member for said peeled veneer disposed on the underside of said pressure bar frame.

  • Patent number: 4494589
    Abstract: A veneer lathe comprising a knife for peeling a veneer from a log, a plurality of pressure nose bars retained as regularly spaced on a pressure bar frame and disposed parallelly to the knife, a plurality of circular discs of a smooth circumferential face interposed between the adjacent pairs of the pressure nose bars and retained in position by the pressure bar frame through the medium of a drive shaft, means for driving the drive shaft, means for inching the pressure bar frame toward the log in proportion as the cutting of the log proceeds, and pressure means for advancing the circular discs toward the log independently of the action of the inching means thereby keeping the log under a substantially constant pressure.
