  • Patent number: 5020403
    Abstract: A web feeding, cutting and dispensing machine includes a pneumatic cylinder for moving a hot wire to cut measured-length sheets from web stock. A pneumatic clamp cylinder moves a clamp bar for momentarily clamping the web during cutting. Upon pressing a start button, a pneumatic control valve sequentially operates the respective cutting and clamping cylinders for quickly retracting the hot wire, while more slowly retracting the clamp. Conversely, after the next measured web length has advanced, this control valve again sequentially operates these two cylinders in reverse order for quickly clamping while slower cutting. This dual control by one valve is advantageously achieved (1) by throttling air flow in retracting the clamp cylinder relative to retracting the cut cylinder, and conversely (2) by throttling air flow in advancing the cut cylinder relative to advancing the clamp cylinder.

    Abstract: A stock feed and cutter system for forging machines and the like in which stationary grippers and linearly movable grippers alternately grip rod or wire stock. The movable grippers reciprocate toward and away from the stationary grippers and operate to feed the stock without slippage a precise distance into a cutter. A stock gage is therefore not required and an optimum cutter structure can be provided even for very short workpieces. After each feed operation, the cutter shears a workpiece from the end of the stock, which is subsequently formed to a desired shape. A running adjustment is provided for the reciprocating grippers so that the machine operator can adjust the length of the workpiece produced while the machine is running. A short blank detector independently measures the length of stock being fed and is connected to cause rejection of such short blank. The grippers operate without slippage and, in cooperation with the cutter, produce very uniform workpieces.

A conveyor transports the garment subassembly to a notching station at which the pre-assembled parts are secured in accurate registration to the path of a notching device that is movable on a carriage toward and away from the notching station. The notching device includes a vertically extending notching blade having a recessed cutting edge which, when positioned at the notching station, overlies an edge of the garment part subassembly. On displacing the blade downward, the notch indicia is cut into the garment piece after which the notching unit is withdrawn to a home position while the notched part is transported by the conveyor to a subsequent fabrication step. In a preferred embodiment two notching devices supported in a common path on opposite sides of the notching station are utilized.

  • Patent number: 4699031
    Abstract: A web of foam material is fed to a cutting station by upper and lower rollers drawing the web from a supply roll and along a low-friction table surface. A cutter station has a knife bar and blade, with a clamp bar coupled with the knife bar. The lower draw roller has its axle mounted in a pair of pivoted arms depressible by presser feet on a presser foot bar carried by the knife bar. When a desired length of web has been drawn past the cutter station, actuation of the knife bar lowers the blade toward a grooved anvil, while the presser feet swing the arms down to depress the lower roller away from the web to stop drawing it. Immediately after interrupting drawing action, the web is clamped by the clamp bar, and then immediately thereafter cutting occurs. The table has bridge-like fingers extending downstream through grooves in the movable lower feed roller. These fingers support the web when the lower roller is swung down.

  • Patent number: 4676130
    Abstract: A carriage on the frame of a lumber edger is driven on tracks longitudinally from one limit to another. Two motors are arranged with their corresponding output shafts coaxial and facing each other. A saw blade is mounted to each shaft. The motors are mounted to laterally extending tracks on the carriage and actuators are provided for shifting the motors, and hence, the parallel saw blades toward and away from each other so that when the saws are translated longitudinally they will rip the irregular edges from a board. A chain conveyor runs through the machine frame and transports the boards to a position under the saws with the length of the boards directed longitudinally. When a rough board arrives under the saws the lines along which the saws will cut are marked on the board with parallel laser light beams. The saws are shifted laterally until the light lines are just inside of both rough edges.

  • Patent number: 4662255
    Abstract: A paper salvage attachment assembly of a paper cutter utilizes a horizontally reciprocable infeed conveyor assembly having an endless conveyor belt which fees bound products to a position beneath the cutting blade of a paper cutter assembly. An outfeed conveyor and stop bar assembly supports the bound product during severance of the spine from the found product. An adjustably positionable stop bar assembly is used to position the vertically reciprocable stop bar at a point downstream of the cutting blade to properly position the bound product so that only its spine will be severed. As the spine is out, the infeed conveyor assembly is retracted away from the paper cutter so that the severed spine may fall through the thus created gap and onto a scrap take away conveyor.
