Zusammenfassung:	A clutching system for films of the same width, but with different frame and perforation format has an adjustable frame support with claws which are operated by a cam via a lever-type feeler. A changeover switch shifts the frame support relative to the film gate plate, and changes the mechanical advantage of the lever of the feeler. The gripping point of the claw frame (3) on the feeler (7) can be altered by sliding the frame support (4). This is done to adjust it to the perforation of the various film formats. The feeler is mounted on a support which can be adjusted to various positions determined by stops. The feeler support (11) can be engaged in the adjustable stops.
