New clich positioning system from Kama

Dresden, Germany-based Kama GmbH has developed a positioning system which enables die-cutter operators to quickly and precisely mount clichs on the cold mounting plate outside of the die-cutter. There are two key factors with the Kama CPX that are claimed to lead to significant time savings: first, clich mounting can be carried out with ultimate precision – including carefully calculated adjustments for shifts resulting from temperature changes – in one easy step. Second, the die-cutter can continue working on other jobs while the mounting process is being carried out.  

This new system is suitable for all positioning for hot foil stamping, holograms and cold embossing, and also for the set up of die cutting tools. This positioning system can also be adjusted to work with the die-cutting and hot foil systems of other manufacturers.

The Kama CPX comprises a positioning table which accommodates the mounting plate, a high-resolution industrial camera, a computer and a monitor. The target position of the clichs is transmitted to the positioning system by reading the workflow files. The positioning program computes the exact, mirrored target position, considering the thermal elongation, and indicates this position on the monitor in the form of a transparent mask. The image of the actual mounting plate, as taken by the camera, is superimposed on this mask. The clich can now be positioned on the mounting plate in congruence with the target position and fixed with great register accuracy in one step. The industrial camera guarantees greatest precision; the ‘all-round lighting’ ensures that the image of the clich is shadow-free.

The program determines the mirrored position of the clich, so that the operator no longer has to think about mirroring the position, thereby eliminating a possible source of error. Precision is also ensured through the temperature-adjusted display of the required position. Extensive trial runs with subsequent corrections in the clich position on the hot plate are no longer necessary.
