ABSTRACT:
A foil web installation for a flat bed embossing machine with foil webs (6), which are conducted across an embossing table (3) from unwinding rolls (7) comprises a braking—and guiding wall (10) ahead of the embossing table and foil feeding devices (9) for several foil webs after the embossing table. Between the unwinding rolls (7) and the embossing table (3) at least one flat braking—and guiding wall (10) acts as a foil tensioning device. This latter element comprises a fixed supporting layer (11) as supporting surface with suction openings (14), a cloth-like contacting layer permeable to air (12) lying on top of it and a flat vacuum chamber (17) with an adjustable vacuum source (13) assigned to it, wherein foil webs (6) are pressed against the braking—and guiding wall (10) and braked as a result of this. This makes possible a foil web installation simple to adjust, easy on the foil web for achieving high embossing performances with the best quality as well as short retooling times.
