  • Patent number: 4330191
    Abstract: A connector device attaches the leading end of a photographic print paper web to a leader belt of a photographic print processor and leads the print paper through the processor. The device includes a belt clip, a leader bar, a pull bar and a flexible connective flap member. When the belt clip is initially attached by an operator to the leader belt, the leader bar (which is rigidly attached to the belt clip) is in a first position which is generally perpendicular to the leader belt. The flexible connective flap member connects the leader bar and the pull bar in a fixed nonparallel relationship. A leading end of the print paper web is attached to the pull bar. When the leader belt is placed in motion, tension is transmitted from the leader belt through the connector device to the print paper web. The tension causes the leader bar to move from the first position to a second position with respect to the leader belt which results in the pull bar moving to a perpendicular position with respect to the leader belt.
