Each packet prior to its being wrapped about the arbor is located so that when wrapped, opposite ends of each group meet in overlapping relationship in a location angularly aligned with said surface portion of concave configuration.

Abstract: A compensating link arrangement is operatively associated with one of two blades in a shear assembly. The angular position of the links may be selectively adjusted to alter a horizontal force component that counteracts a separation force associated with the blades during a cutting stroke. Additionally, a preload bias is provided by a spring to urge the blades together during the cutting stroke. The preload bias minimizes the gap between the cutting blades and provides a precise, burr-free cut of a work material. According to one arrangement, the compensating links are disposed on the lower blade or bed knife. Providing the compensating links on the bed knife is particularly useful in a servo-controlled version of the shear assembly since inertial forces associated with the servo-controlled, movable blade do not affect the bed knife.

Abstract: A device which trims off the perforated margin strips of printer paper and cuts the paper transversely to separate it into individual pages. The paper which discharges from the printer is drawn around a tension bar and is applied to a toothed belt driven by feed wheels. Cutter wheels act against a grooved roller to cut along the tear lines of the margin strips. A photocell based counting system counts the perforations which pass the photocell to indicate each time the paper is advanced to position one of the transverse fold lines at a cutting station. Then, the paper is stopped and a cutter wire is pulled through the fold line to separate the leading page from the rest of the paper sheet. Each time a new sheet of paper is loaded, a special control circuit assures that the initial advance of the sheet stops with the leading edge of the paper at the cutting station.

Abstract: The invention provides a punch press and shearing tool which operate to provide a series of cuts linked end-to-end for severing a work piece such as a piece of sheet metal. The shearing tool includes first and second elongated, cooperating cutting blades. Each of the blades has a pair of slidably related faces that slide against one another in a plane of reciprocation. The cutting edges are oriented at a small angle, e.g. 2.degree. to 6.degree., relative to one another to sever a piece of sheet stock progressively along a line with a scissor action. An intermittent work piece advancing motor shifts the work piece toward the cutting blades and parallel to the cut when the blades are apart. Gripping members can be yieldably mounted adjacent the cutting blades to grasp and forcefully hold the work piece in place as one blade moves toward the other. Yieldable stripper members on opposite sides of the second blade engage and independently deal with the stock on opposite sides of the cut.

Abstract: In a cutting table for sheet metal and the like, the portion of the work that overhangs the table where it is cut is supported on a traveling adjustable support (9) having rollers on its upper surface. As the upper blade is brought down to cut the work progressively from the side near the pivot of the blade to the opposite side, a traveling carriage on which the traveling support is mounted is caused to move along the length of the cut so that it provides support to the work at the location where the blade is doing the cutting. The support is pivoted on an axis perpendicular to the cut so that it can adjust itself to the inclination of the upper cutting blade, the pivot being fixed on a vertically slidable member guided in the carriage. Hydraulically driven pistons enable the support to be raised or lowered with respect to the carriage. Wide cuts can thus be made without the strip that is cut off being twisted, coiled up, or otherwise deformed.
