Process and assembly to heat shape foil e.g. foil packaging material held in situ by three or more suction beams

摘要

In a process to apply a coating to one side of a foil sheet bearing a marking, the foil is introduced to a forming station (3) with three or more suction beams (20, 21, 22). The beams are height-adjustable. Their presentation may be altered at any angle transverse to the height axis. Also claimed is a commensurate assembly.
