Abstract: For separating off a stack of individual shaped items such as bottle neck labels from a stack of strips each carrying several such items, a punching die is used which has a punching contour which corresponds to the desired shape of the cutting line between the individual shaped items. The cutting line also corresponds to the rear contour of the separate stack of individual shaped items. The shape of the cutting line of the punching die is freely selectable. At its rear edge the punching die is smooth and the separated-off stack of shaped items accommodates any compression of the material forming the stack by means of an offset angle so that the remainder of the strip of shaped items has a smooth and perpendicular cut edge.

Abstract: The portable washer cutter of this invention comprises a pair of enclosures adapted to be interconnected and operative to rotate to progressively close the two enclosures together.

Abstract: An improved quick clamping device to hold armored cables such as BX cable for cutting. The device includes a handle for receiving the cable which is preferably U-shaped and which defines a cable receiving channel. A clamping handle is hingedly attached to one end of the cable receiving handle. A clamping stud with a two-sided stop adjustable along its length is slidably held between the clamping and receiving handles such that when the handles are compressed the clamping stud projects into the cable receiving channel and clamps the cable. A spring biasing means on one side of the stop serves to hold the handles in the open, unclamped position prior to use. A resilient means such as a bowed spring steel washer is provided on the other side of the stop which compresses as required to prevent excess clamping forces from being generated which might damage the clamp. A saw is preferably mounted on a pivoted saw handle to cut the cable which it is clamped.

Abstract: Frame members of the apparatus mount cutter assemblies that are aligned by relative adjustive movement of the frame members with edges of a cutout that is to be cut from sheet material. The adjustive relative movement of the frame members additionally effects adjustment of the relative positions of the cutter assemblies and associated cam members also carried by the frame members. This in turn causes the cuts made by the cutter assemblies to be of the same length as the therewith aligned cutout edges. The apparatus preferably further includes clamping members that engages the sheet material during each cutting operation, and drive components for imparting desired motions to the various movable components of the apparatus.

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.

Abstract: An arrangement for diagonally cutting up the end of a rectangular tube is provided. In order to be able to utilize the shearing principle with such diagonal cuts, the clamping jaws are arranged as stationary shearing blades having shearing edges that define a cutting plane. The rectangular tube being cut to size is diagonally inserted between the clamping jaws so that a pocket which is to be cut off stands out beyond the cutting plane. A shearing knife moves along the pocket and has an arrow-like shearing edge which inserts into this pocket-shaped projecting end and cuts off the end from the inside against the stationary cutting blade. Each of the three stationary cutting edges is brushed off by the movable cutting edge by at least one movable component.

Abstract: An apparatus for use in a tube manufacturing plant wherein a coiled strip is made into a continuous tube. The tube is fed to the apparatus at a given speed and severed into a specified length with minimized errors in accordance with the contemplated use by a cutting assembly traveling in synchronism with the feed of the tube. When the speed of the cutting assembly matches the speed of the tube, a ram is lowered from above by a crank assembly to cause a notching blade and a cutoff blade to cut the tube without dimples. The ram is elongated and supported by a plurality of crankshafts which are adapted for synchronous rotation optimally by a synchronizing link. For dimpleless cutting, the notching blade is revolved and thereby moved at an increased speed to form a deep and wide notch in the tube.

Abstract: The present invention relates to an apparatus for cutting motion picture film negatives. The improvements in the present invention film cutting apparatus enable the film cutter to cut the motion picture film negative with a precise, even, clean cut at a location mid-way between adjacent frames of film footage. This is necessary when using a new technique of negative cutting and splicing that allows no frame loss and still maintains all of the requirements of professional (state of the art) motion picture film processing. This has never before been done. The improvements include individual film seating plates which press the lengths of motion picture film to be cut against individual film support and ejection plates to assure that the lengths of film are securely held prior to and during the cutting operation. The present invention also provides safety features to assure that the operator will not accidentally cut himself during the operation.

Abstract: A forging (A) is received in a split ring (B) which provides peripheral support to a forging peripheral wall (14) and an upper peripheral flange (16). The forging and the split ring are supported by a nest member assembly (C) as a trimming assembly (D) moves longitudinally to trim the forging flange and a forging bore (10). A punch (74) with a hardened cutting edge (80) moves axially through the forging bore and interacts with a nesting assembly cutting edge (60) to trim the bore. Concurrently, a trim die (90) having a cutting edge (96) interacts with a split die cutting edge (36) trimming the upper flange. The split ring restrains a central portion of the forging from puffing peripherally outward in response to the punch being urged therethrough. The interaction of the trim die and the split ring inhibits the upper part of the forging adjacent the upper flange from being drawn in toward the forging bore by the interaction between the punch and forging.
