Abstract

The process of blocking the movement of film loops in a camera loader permits maintenance of the film loops in place during transport of the loader. The film loop blocking mechanism is removed when the film loader is placed on the camera. The blocking mechanism consists of an axis (9) which slides in a slot (8). The ends of the rods slide in their turn in their own slot (14, 15). The slots (14, 15) in which the ends of the rods slide are in the form of a V so that they move apart when their common axis (9) slides in its own slot (8) situated in the middle of the V. The ends of the rods can be connected to a hinge curved piece (16) shaped in the form of the film loop or simply fitted with rollers (19, 20) which separate the two lateral walls of the loop.
