Abstract

A device for automatic loading of film material on a suction plate by transport roller pairs arranged at two oppositely disposed ends of the suction plate. One pair receives the film material and the other pair further transports the film material. At the two other lateral sides or ends of the suction plate, a roller is respectively provided extending over an entire side of the plate. A cloth can be wound on this roller such that the roller and cloth are so arranged that they respectively form a blind covering the suction plate up to and overlapping lateral edges of the film material.
