  • Device for clamping and releasing film material and operation of said device
    Patent number: 5500656
    Abstract: In order to improve a device for clamping and unclamping film material (3) on and from a stationary holder (12) in which the film material is taken by a transport device (4 to 8) through the holder (12) especially from an inlet to an outlet slot, and held in the holder (12) during exposure, in such a way that the film material can be reliably positioned in the holder (12), it is proposed that a positioning unit (19) be fitted which confers upon the film material (3) a tendency to move against the direction of transport when it is clamped.
