Abstract: A machine for feeding products in strip form to a photographic printer. The machine includes a plurality of feed magazines disposed on a rotary turret. When it is desired to use an external strip feed source, for example a large-capacity magazine, use is made of an interfacing device defining a guide path connecting the discharge slot on the external strip feed source to the inlet slot on the machine. At least part of the guide path of the interfacing device is rotatable with the rotary turret.

Abstract: An interface device (10) connects in a light tight manner a feeding device (11) with a receiving station (12) fitted with a feed opening (13) and a driving device (60) liable to move a web (153) inserted into the feed opening (13) with a given tension force. Provided are first means for connecting the interface device (10) to the feeding device (11) and a second means for connecting the interface device (10) to the receiving station (12). A driving roller (42) is provided for pulling the web (153) out of the feeding device (11) in order to form a loop (53) which controls a regulating system (56). Regulating system (56) controls the speed of the rotation of motor (41) connected to driving roller (42).
