Abstract: A cutter for cutting continuous stock materials into discrete lengths is disclosed. The cutting device includes a plurality of rotatable cutting tools or blades extending transversely across a cutting zone. The cutting tools are mounted in a common plane, are intermeshed, and are synchronously driven in opposite directions. The cutting zones of the intermeshed cutting tools overlap and thus the cutting device is capable of performing the cutting operation by movement in one direction through the material being cut. The cutting tools have opposed segments that carry cutting edges. In one form of tool, the cutting edges are spaced from the axis of rotation of the cutting tool by a distance that continuously increases in a direction opposite the direction of rotation of the cutting tool. This change in distance can be related to the speed of rotation of the cutting tools and the speed at which the cutting tools are advanced through the material being cut.

Abstract: Resilient articles, such as, mattresses and cushions of varying yield resistance to accommodate the weight variation of the body and/or to provide edge support are produced by tailoring tensile forces within the article. Tensile force variation may be accomplished in articles of uniform density by slotting to separate adjacent regions in at least one direction. Tailoring is accomplished by variation in slot depth and/or spacing.

Abstract: An alignment and stacking arrangement for stampings manufactured in a continuous stamping operation by a stamping machine having a punch and associated punch matrix. At least one stacking channel is arranged in the punch matrix for receiving the stampings with an intermediate stack forming device being arranged at the stamping machine at a position below and independent of the punch matrix. The intermediate stack forming device may include at least one locking pawl for reducing the clearance of the stacking channel and/or a mandrel arranged in the stacking channel which is selectively engaged by a holding element during the formation of the intermediate stack. A stacking mandrel or stacking shaft is associated with the mandrel and is displaceable so as to permit a stack of stampings of a predetermined height to be carried away from the stamping machine by a conveyor arrangement.

Abstract: A method of severing useful lengths connected together by small fillets in a sheet of paper, pasteboard or the like, comprises applying the sheets on to a substantially non-flexible support having a contact surface of a first coefficient of friction, and then exerting on adjacent useful lengths, through forces which act in opposite directions tangentially on said adjacent useful lengths with a contact pressure by way of a second coefficient of friction exceeding the value of said first coefficient of friction, a splaying movement sufficient to destroy the fillets. Apparatus for carrying out the method may comprise a press, pressure fingers disposed at both sides of the longitudinal axis of said press, and contact surfaces having said comparatively high second coefficient of friction and at the free ends of said pressure fingers, said contact surfaces being intended for application to the useful lengths to be severed.

Abstract: Apparatus for cutting shaped articles from thin material. By way of example, the material can be uncooked dough and the articles can be preforms which are further processed into snack food chips. A rotary cutter includes a first roller having a cylindrical surface with a plurality of article cutters positioned around and projecting outwardly from the cylindrical surface.

Abstract: A method and apparatus for acting on angle irons or the like. A vertical stack of angle irons is provided and the angle irons are fed one at a time to a punching position. At the punching position a hole of selected size is punched in the angle iron, and the angle iron is fed from the punching position in a linear direction of movement to a cutting position. The length of the angle iron to be cut is determined by measuring the length of angle iron in the direction of movement past the cutting position, and the angle iron is cut at the cutting position. Each cut angle iron is removed from the cutting position in a direction normal to the linear direction of movement of the angle iron to the cutting position. A computer may be provided for controlling operation of all motors to affect selection of punch sizes and cutting blades, and to affect operation of all the power mechanisms.

Abstract: In shearing apparatus comprising a fixed and a movable shear element for shearing work such as wire into desired lengths, a stop member is provided for stopping the wire as same is fed endwise through the fixed shear element. Each time the wire length projecting out of the fixed shear element is cut off, the stop member is pivoted against the force of a spring to relieve the impact of the shearing operation exerted thereon. For adjustably moving the stop member toward and away from the fixed shear element, the stop member is mounted on a carriage having a tapped hole through which extends a threaded first shaft geared to a second shaft. This second shaft can be rotated manually for moving the carriage toward or away from the fixed shear element and can be locked in a desired angular position by a locking pin which is spring biased into engagement in any of several circumferentially spaced indentations formed in a collar on the second shaft.
