Abstract (en)

[origin: WO2016086325A1] The flat foil printing press has an evacuable back-pressure plate (9), with suction regions (15k) which run in the sheet running direction (X) next to embossing regions (16k), in which foil webs (6k) run. The suction regions are divided into a plurality of suction segments (10i) which follow one another in the sheet running direction and in each case are connected by way of a vacuum feed line (12i) via a vacuum switching element (13i) to a vacuum source (14). When an embossed sheet (5) runs out, first of all all the suction segments (10i) which are covered by the sheet are evacuated, and subsequently the suction segments which are no longer covered by the sheet are switched off one after another from the vacuum source. This results in fault-free separation of foil webs and sheets for higher image quality and machine performance.
