Deviation device for a web of film
摘要:
A deviation device for a film web has at least one deviation element, which operatively interacts with the film web at the point of deviation of the film web and guides the film web on an air cushion. The deviation element can be rotated and has a drive device, which sets the deviation element into rotation so that the peripheral speed of the deviation element differs from the transport speed of the film web.
