Definitions

  • the invention relates to a folding box gluing machine with flat sheet-like paper, cardboard or the like control devices according to the preamble of claim 1 and to a method of controlling the Braille embossing module according to claim 7.
  • the sheets are first printed wide web in a printing press. On the sheets, several benefits of the cartons to be produced are printed in each case, which are then punched out in a punch. The punched-out folding box blanks are then fed to a folding box gluing machine and processed here into folding boxes.
