A modified fixed bracket with a larger fine-threaded hole is used to retain a hollow micro adjuster screw which is engaged by the fine threads of the bracket. The retaining screw that attaches to the die now does so by being inserted through the hollow body of the micro adjuster screw and out of a clearance hole at the distal end. Fine lateral adjustments of lateral alignment between the paper to be punched and the die can now be performed by moving the die laterally.

Abstract: A device for trimming and automatically cutting of either multiple or single images is described produced for example through digital rendering on paper and other graphic and photographic substrates, wound in reel or being in single sheets (10), especially of large size. The problems met in using known devices of this type with feeding rollers (2) with a length corresponding to the substrate width have the consequence of a slowing down of the production owing to the excessive care to be taken when introducing at the same time parallel sheets of large size. These problems can be overcome by using rollers of reduced length, but only by adding errors in the forward movement of the substrate, errors which are remedied by means of optical sensors (4, 4′) for detecting the separation mark (M) between the images (10a, 10b . . . ) as well as its angle with respect to the cutting line (7), and by a pair of length differences measuring devices (6).

A linearly movable die driver is operatively connected to the output shaft such that (a) rotating the shaft in the first rotational direction thereof moves the die driver generally linearly in a first die driving direction and (b) rotating the shaft in the second rotational direction thereof moves the die driver generally linearly in a second die driving direction opposite the first die driving direction.

Abstract: Apparatus and a method for production of laminated electronic or electrical devices are described which enables one thin patterned or unpatterned substrate to be easily and accurately incorporated into a previous stack of substrates by registration of a coated tape from which the substrate is excised. In the present invention the tape is indexed to a fixed position and then a platen with the previously stacked substrates is brought into registration with the stationary tape, following which the substrate is excised from the coated tape and added to the stack of substrates. Since the tape always is positioned in the equipment as indexed at the same location with each indexing step, and since once indexed the tape does not move, the platen can be brought into accurate alignment and registration with the tape.
