ABSTRACT:
The invention relates to a device for embossing and/or glazing films. The device for embossing includes a first and second embossing roll, through which flat material can be fed under pressure, in order to create a pattern. An additional embossing roll is connected downstream of the second embossing roll, this additional embossing roll interacting with the first or preceding embossing roll. The patterned flat material may be fed between these embossing rolls, in order to be embossed again with essentially the same pattern. In a simplified embodiment, only a total of two rolls are used. In order to achieve as precise an embossing as possible, with special effects, the first driven embossing roll is provided with teeth, while at least one other embossing roll comprises rings or longitudinal ribs, or is smooth.
