Rotary Tool Patents (Class 69/37)
  • Publication number: 20150059419
    Abstract: A method and an apparatus (1) is disclosed for processing the skin side of a tubular fur (2) arranged on a mandrel (4) so that the skin side of the fur (2) faces outwards, comprising the steps of processing the skin side of the tubular fur (2) by mutually displacing the mandrel (4) and a processing device (5, 5a, 5b, 6, 6a, 6b, 7, 8, 8a, 9, 9a) in a longitudinal direction of the mandrel (4) while said processing device engages the skin side of the tubular fur (2), determining a transition between a lower end part (2a) of the tubular fur (2) and a surface (4c) of the mandrel (4) by means of mutually displacing the mandrel (4) and a colour sensor (10) directed towards the mandrel (4) in a longitudinal direction of the mandrel (4), and terminating the processing step in dependence of said determined transition.

  • Patent number: 5941101
    Abstract: A belt edge burnishing machine for burnishing the edges of a plurality of belts simultaneously. The belt edge burnishing machine comprises a conveyor and at least one buffing wheel positioned above the conveyor which is rotated about an axis parallel to the ground and to the conveyor. The belts are stacked on an edges finish board with the unfinished edges facing up. The edge finish board is placed on the conveyor which conveys the plurality of belts through the burnishing machine. As the belts pass beneath the rotating buffing wheel, the buffing wheel contacts all of the exposed unfinished edges, thus buffing the edges smooth.

  • Patent number: 5582041
    Abstract: The tool includes a linear housing, a thin circular fleshing blade with a cutting edge around its perimeter, and a guard member. The housing encompasses an air-driven or electric motor and serves as a handle. A rotary drive shaft projects at an angle from an end of the handle, and the free end of the drive shaft is equipped to have the blade mounted thereon. The guard member is mountable on the housing to cover a substantial portion of the blade. The angular displacement of the drive shaft and blade from the handle enables the user to conduct a fleshing operation with a backhand stroke that is easier to control than a forward thrust motion.

  • Patent number: 4993243
    Abstract: A portable fleshing tool has a thin, circular blade mounted on a drive shaft of a motor. A front and a rear guard substantially protect the blade, with the rear guard removably attachable to the housing of the motor and the front guard removably attachable to the rear guard. The front guard is slightly vertically adjustable to permit slight adjustment of the depth of a fleshing cut because the fleshing blade is being operated in a plane perpendicular to the plane of the pelt or hide being fleshed.

  • Patent number: 4989427
    Abstract: A fleshing machine for removing fat and fleshy membranes from a hide or pelt, which includes a fixed position roller with many shaped cavities. Each cavity extends from an opening on the surface of the roller into the roller. A plurality of knives are contained one or more within each cavity. Each knife has a shaped cutting head which, in use, protrudes from the surface of the roller. The knives and cavities are so shaped that each knife is capable of limited reciprocal movement in a direction perpendicular to the axis of the roller.

  • Patent number: 4542634
    Abstract: In a staking machine for staking leather, skins or furs a rotatable work roll carrying staking blades or grindstones is arranged against a flexible pressing device with an adjustable gap. A workpiece is pulled through the gap by a rotary feed roll and a rotary clamping roll also arranged at an adjustable clearance. The workpiece is fed through the gap between the feed roll and the clamping roll when the feed roll cooperates with the clamping roll.

  • Patent number: 4348837
    Abstract: A felt pad having a beveled front end is produced from a workpiece having a flat bottom with an adhesive thereon covered with a strip of paper or the like and a straight front end. The apparatus includes a rotatable shaft having mounted thereon an abrasive wheel and a wire brush wheel including a cylindrical portion of the same diameter as the abrasive wheel abutting the abrasive wheel and a tapered portion extending toward the shaft axis. A shear plate provides a cutting surface with the abrasive wheel. The workpiece is mounted on a table and fed parallel to the shaft axis with its forward end also parallel thereto. The rotating brush bevels the front end of the pad and fuzz still attached to the pad is removed as it passes between the abrasive wheel and shear plate. A shroud surrounds the wheels and a suction is applied thereto to draw off the materials removed from the workpiece.
