Abstract: A nail flattening apparatus for use primarily in re-furbishing wooden pallet components, comprising a loading station and an operating station interconnected by a conveyor. Boards having nail stubble protruding from opposite sides are placed onto the conveyor in the loading station and transferred to the operating station, whereupon a reciprocating hammer and stationary anvil disposed on opposite sides of the conveyor cooperate to substantially flatten all nail stubble in a single operation. In the preferred embodiment, a microprocessor controls a plurality of hydraulic cylinders which automatically move each board into the proper operating position, lift each board off of the surface of the conveyor, move the hammer to compress substantially all nail stubble, release the hammer to its retracted position, return the board to the conveyor for transfer out of the operating station, and move the next board from the loading station into the operating station.

Abstract: A power stapler having a clincher provides a stitcher head for driving formed staples into a stack of sheets. A clincher box is positioned opposite the stitcher head. Clinchers located in the clincher box pivot upwardly under the force of a moving clincher bar to deform ends of the staple to pass through the sheet stack. The clincher bar or clinchers include a stop that limits retraction of the clinchers into the box. Hence, as the staple is driven by the stitcher head through the sheets, the ends of the staple are brought into engagement with the clinchers and plastically deform into a substantially inwardly curled shape. Following driving of the staple by the stitcher head, the clincher bar is actuated to rotate the clinchers upwardly toward the stack causing the curled tips of the staple to drive into the sheets. The clinchers can include grooves that are angled into alignment along parallel angled lines so that the ends of the staple pass each other and do not interfere with each other upon clinching.

Abstract: In the course of the upward turning movement of the magazine, the lowermost sheet of staples is taken from the staple cartridge as the feeding member is slidably displaced in the forward direction. Since the thrusting force given by the tension spring is sufficiently larger than the frictional resistance present between the lower surface of the lowermost sheet of staples and the feeding member, each sheet of staples can be more reliably taken from a staple cartridge. As the magazine is turned in an upward direction, a feeding member is displaced in the forward direction by the resilient force of a tension spring, and a contact portion on the feeding member comes in contact with the rear end of the lowermost sheet of staples.

Abstract: A rotary stapling machine includes a first rotatable roller, a staple retainer mounted on the first roller to retain a U-shaped staple in a predetermined orientation, and a second rotatable roller having a die.

Abstract: A stapling device (1) comprises a clincher unit (3) with bending elements (30 and 31) by which the ends of a staple (34) driven through a sheet stack (35) are folded and bent onto the sheet stack (35). The bending elements (30, 31) are actuated by a pushrod (26, 27) whose end side facing the bending elements (30, 31) is provided with rotary rollers (28, 29) which roll on the bending elements (30, 31) during each working stroke in order to clinch the ends of the staples. During the return stroke of pushrod (26, 27) the reduced frictional load causes slippage to occur between the rollers (28, 29) and the bending elements (30, 31) so that continuously alternating contact points are brought into engagement. This results in a uniformly distributed, and consequently reduced, load on the rollers (28, 29) by which the service life of the clincher unit (3) is prolonged.
