An accumulator is provided for use with a production line formed by two or more standardized modular production units for receiving product supporting carriers in sequence from one production unit, advancing the carriers along a serpentine path of travel of a given length, and for thereafter advancing the carriers onto the next production unit. The accumulator includes a plurality of side-by-side conveyors and corresponding passive turnaround guide bars responsive to motion imparted to the carriers by next adjacent conveyors moving in opposite directions for deflecting the carriers from one conveyor to the next adjacent conveyor while at the same time effecting the turning of the carriers through approximately 180.degree..

Accumulator for use with modular production line units

Apparatus for cutting a portion of a visible image from a film unit and mounting the same in a frame or slide holder of the type adapted to be received by a slide projector. The apparatus includes a female die upon which the film unit is supported and an elongate member having one end pivotally connected to a fixed support and its opposite end constructed to pivotally receive a male die thereby enabling the male die to self-align itself within the female die as the elongate member is rotated about its pivotal connection to the fixed support during the cutting or severing operation. A manually operative film advancing apparatus is provided for engaging an edge of the severed portion of the film unit and moving it into a chamber containing a plurality of open-ended slide mounts. As the severed portion is advanced into the chamber, its leading edge enters one of the mounts via its open end. The advancement of the severed portion is continued until it is fully seated or secured within the mount at which time the film advancing apparatus engages the mount and advances it to a position wherein it may be grasped and removed from the chamber.

Slide cutting and mounting apparatus

An improved cylindrical processing roller is provided for use in a motor driven photographic processing apparatus of the type which spreads a fluid processing composition in a thin, substantially uniform layer between selected layers of integral type self-processable film units while advancing a film unit to the exterior of a camera after photoexposure. The improvement in the roller resides in a novel circumferential roller surface roughened by electrical discharge machining techniques to provide the roller with a high-friction characteristic for transporting the film units while being insufficiently rough to leave any visually perceptible marks on a film unit.
