Abstract: A punching device includes a detecting unit, a punching unit, a moving unit, a storage unit, and a controlling unit. The detecting unit detects a lateral edge position of a recording medium to obtain edge position data. When the edge position data does not indicate an error value, the edge position data is stored in the storage unit as reference data. The controlling unit determines, when the edge position data indicates an error value, a movement amount of the punching unit based on reference data previously obtained and stored in the storage unit. The moving unit moves the punching unit by the movement amount in a direction perpendicular to the conveying direction of the recording medium.

The shear device includes a material guiding mechanism, a shear head including a shear blade disposed proximate the material guiding mechanism, and a linkage for translating a first movement of one of the shear head and the material guiding mechanism into a second movement of the other of the shear head and the material guiding mechanism. A method is also disclosed.

Abstract: A cutting apparatus for ductile materials comprises a nozzle having a number of outlet openings separated from each other by separator webs. Next to the nozzle, a rotating cutting tool is provided, having a plurality of cutting knives for cutting off the strands of material discharged through the outlet openings of the nozzle. Each separator web is at least as wide as a cutting knife. For performing a cutting operation, the cutting tool is intermittently rotated. Between two cutting operations, the cutting tool is stopped, whereby its knives remain in a rest position behind the separator webs. For the next cutting operation, the cutting tool is rotated by such an amount that its cutting knives move from a position behind a first separator web to the next adjacent separator web.

Abstract: A groove stamping machine stamps the required grooves successively into a disk-shaped blank particularly for manufacturing stator and rotor plates for electric machines. The groove stamping machine has a stationary bench which, on the end side, carries a spacing apparatus for receiving the blank. A stamping device disposed on the bench is adjustable with respect to the spacing apparatus. The distance between the spacing apparatus and the stamping device can be adjusted by a ball thread spindle which acts between the spacing apparatus and the stamping device. The fixing of an adjusted distance takes place by the blocking of the ball thread spindle, preferably by way of a disk brake. The stamping device is disposed via a combined roller slide bearing on the bench which permits a low-friction displacement of the stamping device which also supporting the latter in a stiff manner.

Abstract: A machine for trimming the edges of stacked paper sheets at a trimming station has a conveyor which delivers successive stacks to the trimming station, several knives which are movable from raised positions to lower end positions to thereby trim the respective edges of a stack at the trimming station, anvil blocks which are penetrated into by the cutting edges of the knives when the knives complete their working strokes subsequent to trimming of a stack, and a control unit which prevents the knives from contacting the respective blocks if the knives perform working strokes in the absence of a stack at the trimming station. The control unit can shift the working strokes of the knives and/or lower the blocks to thus ensure that the cutting edges of the knives are arrested short of the respective blocks when a photocell detects the absence of a stack at the trimming station while the knives perform their working strokes.

Abstract: This machine is more particularly designed to make a series of slits across the external surface of a tire rethread band. The band is moved step-by-step by a conveyor belt; a guillotine-type blade is reciprocated up-and-down over the band supported by the conveyor belt and effects a slit in the band when the conveyor is stopped; the depth of the slits can be adjusted; the inclination of the slits with respect to the longitudinal axis of the band can be varied; the distance between the slits can be adjusted by varying the stroke of the belt advancing mechanism; the conveyor belt has an outer anti-skid surface and the tire rethread band is applied against the same by spring-biased pressure rollers which accommodate tire rethread bands of various thicknesses.

Abstract: In punching, cutting and forming presses and the like, electronic detecting means and/or sensors are provided so as to trip the press and prevent an operation when a mal-function occurs such as a tear in the strip material or a mis-alignment or a mis-feeding of the strip. When the press is equipped with an elbow arrangement to permit adjustments for feed line height while maintaining feed cycle synchronization, then the arrangement must incorporate the automated locking device of the invention, the same automatically unlocking the swing plate simultaneously with the tripping of the press.
