Fully automatic equipment for printing, testing and splitting up paper web - uses microprocessor as control unit delivering information set in parameter block as well as transition of pulse track derived, e.g. from perforations, margin.

摘要

By means of characters and synchronisation, the continuous strip of clear or punched paper strip can be printed at desired sections with information required in a single pass, selectively on the top or underneath side. In the case of perforated continuous strip it is ensured that only the non-punched, horizontal and vertical areas are printed. The sum of the spacing between the punched holes as well as the widths of the holes and margins are tested for regularity. The equipment can be controlled by the continuous web to be printed. ADVANTAGE - Copes with paper of various widths and allows section to be printed to be selected. Allows batches to be selected, cut, separated and wound.
