Abstract: A drive arrangement for a high speed mechanical press, especially a high speed cutting press, wherein the press drive includes two eccentric shafts connected by connecting rods with a slide. Mass balancing weights are provided for enabling a complete dynamic mass balancing, with the weights being articulated by additional rods and being moved in a direction opposite to the slide. The drive further includes at least three pairs of toggle or knee joint link arrangements, with the first arrangement being nearly horizontally disposed, the second arrangement being nearly vertically disposed, and the third arrangement being nearly vertically disposed and connected on the one hand with the slide and, on the other hand, with the mass balancing weights, with the pairs being arranged symmetrically with respect to the eccentric shafts.

Abstract: A cutter assembly is provided for cutting continuous strips of a dough product, such as potato dough, into a plurality of relatively short strip segments with a variety of lengths and angular end cuts.

Abstract: A press drive with a central cam shaft actively connected through a connecting rod with a slide guided in a linear guide. Side bars are symmetrically articulated with respect to each other on the slide. Mass balancing weights are driven in opposed directions corresponding to reciprocating masses of the press, with the weights being connected with the slide by other linkages. Pairs of toggle joint linkages are disposed symetrically with respect to the cam shaft. The pairs of toggle joint linkages include a first almost horizontally disposed toggle joint linkage that is articulated on the respective side bars and presents a bearing point on the press frame. A second almost vertically disposed toggle joint linkage that is connected with the first toggle joint linkage and is articulated so as to be guided by the press frame on the mass balancing weight.

Abstract: A swinging ram type cutoff press for severing lengths of elongated stock such as tubing is provided of the type in which a ram is supported for swinging movement to operate a cutoff die set. The cutoff press includes a power cylinder combined with a toggle link arrangement to produce the swinging movement of the ram. The relative geometry of the ram link support and the toggle mechanism coupled with the arrangement of the cylinder is such that a complete ram motion cycle is carried out during a single forward or return stroke of the cylinder. The force exerted by the cylinder and toggle mechanism is not resisted either by return springs or the weight of the ram, thereby further maximizing the usable power of the power cylinder. Accordingly, one may reduce the cylinder size requirements for a given application. In addition, the mechanical advantage afforded by the toggle mechanism provides for a maximum force at the ram full down position to maximize the force available for the blade stroke.

Abstract: A base defining an upwardly facing sheet supporting surface and an elongated support member is mounted on the base and projects upwardly from the sheet support surface. The support member includes spacer structure spacing portions of the support member from the base to define an open slot between the base and the spaced portions of the support member. A pair of aligned support blocks are supported from the support member above the opposite end portions of the slot and an elongated head extends between and is removably journaled from the support blocks. The portions of the support member spaced above the base define upstanding sleeve bores therein normal and opening into the slot and bearing sleeves are mounted in the sleeve bores and have elongated punch members reciprocately disposed therein. The base defines die bores below the slot and opening into the latter aligned with the sleeve bores. Die sleeves are disposed in the die bores.

Abstract: A hydraulic fluid shock dampening system is disclosed for a shearing press to minimize shock and vibration imposed on the press following breakthrough of the material being sheared by cutting die components carried by the press bed and slide. The system includes cylinder and piston units interposed between the press bed and slide each providing a variable volume fluid receiving chamber from which fluid under pressure is expelled during movement of the slide toward the bed to achieve a shearing operation. A flow sensitive shutoff valve is responsive to accelerated movement of the slide upon breakthrough to block fluid flow from the chambers and thus restrain further slide movement toward the press bed. In preferred structural embodiments of the system, the cylinder and piston units, shutoff valve and fluid pressure accumulator components are structurally associated with a bolster plate mountable on a press, or with die components mountable on a bolster plate.

Abstract: A tubing notcher which comprises a housing having a longitudinally slidable cutter assembly attached thereto. The cutter assembly is to be manually moved through an appropriate actuation means connected to the cutter assembly. The cutter assembly includes a cutter which has an arcuate cutting edge. A tube, the open end of which is to be notched, is to be located upon a guide means which is fixedly secured to the housing. The guide means is inclined slightly less than a right angle in respect to the longitudinal axis of movement of the cutter. The cutter is to be located within the open end of the tube and upon movement of the cutter the open end of the tube is appropriately notched.

Abstract: A piercing punch, a piercing die and a swaging punch are displaced relative to each other to produce locking joints by a machine which uses cams, preferably in the form of pairs of mating, wedge-shaped blocks to produce the necessary reciprocating movements of one or more of the three tool elements. A suitable kinematic actuating device, preferably in the form of a toggle linkage reciprocates the third tool element.The interaction of these elements is such that exceptionally favorable conditions for joint formation prevail.

Abstract: A machine for clipping strip material including a blade operated in a cyclic manner having a cutting stroke and a return stroke. A toggle linkage including a toggle bar effecting one blade cycle by moving in a lengthwise direction with the blade being reciprocated by toggle linkages moving through an upright position to a position oppositely inclined to their starting position. The toggle bar is coupled to an actuating piston rod of a pneumatic cylinder. End caps of the cylinder are recessed to receive piston extensions during final stages of piston travel for cushioning purposes. Seal means engage each piston extension during the later stage of piston travel to trap air between the advancing piston and the end cap. Accordingly, blade and toggle assembly inertia is dissipated in the compression of trapped cylinder air. Exhaust means within each of said end caps is valve controlled to release cylinder pressure at a desired pressure braking the latter stages of piston travel.

Abstract: A device for cutting strip material across its length has a single plate frame in which a tool slide is reciprocable by a toggle linkage driven by moving cylinders the piston rods of which are fixed to the frame. Fluid delivered by way of passages in the piston rods powers the movement of the cylinders for smooth vibration free action. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Abstract: An anvil roll has a steel core and an outer portion of polyurethane. The roll is slightly rotated after a number of veneer clipping operations by a clutch which drives the roll after the roll is pushed by a knife down away from arcuate braking surfaces. An airbag normally urges the roll into engagement with the braking surfaces and is collapsed during adjustment of the roll. Operation of the clutch is prevented during the clipping operation. A double-acting cylinder drives the knife through a toggle joint linkage, and cushioning cylinder means aid in overcoming inertia of the knife at the start of a clipping cycle and also cushion the return of the knife. The cylinder has poppet check valves to rapidly admit air thereto.

Abstract: A packaging machine is provided in which wire is fed for cutting into predetermined lengths for subsequent formation into U-shaped clips for clinching about a constricted product filled tube. It includes means for varying the length of the cut off portion by adjusting the position of a wire receiving member or cut off round and a cut off knife along the wire. Also the wire is fed intermittently to be cut off through an extent corresponding to the length to be cut off. The cut off length is variably formed according to the desired length of the U-shaped clip with the legs thereof in various angular relations.
