  • Patent number: 6485777
    Abstract: A device for coating a sheet comprises at least one screen cylinder configured to be positioned downstream of a sheet feeding mechanism. The screen cylinder is further configured to coat a sheet. The device further comprises a constant conveyor for feeding a sheet from the feeding mechanism to the screen cylinder and a variable speed drive for rotating the screen cylinder. The variable speed drive is configured to rotate the screen cylinder based on one of a print length and a print position of the sheet to be coated.

  • Patent number: 5639335
    Abstract: To enhance printed products, lamination is to be carried out by of a controllable pair of laminating rollers, rather than by the conventional method of calender rolling. To do this, the film is applied with relatively low contact-pressure roller pressure in a floating manner. The film can be fed to the laminating rollers without tension by means of a controllable applicator mechanism with a film tension regulating device. The processing rate and sheet length, for example, can be entered by computer so as to control the sequence of the feeder output and also the sequence of a wet cutting device via a suitable incremental-value transmitter from the main drive. Accordingly, processing rates of 60 to 100 meters per minute can easily be set. The quality remains good even at the highest speeds.
