Abstract

A motion picture film shipping and handling unit is adaptable for use on either a platter-type movie projector system or on a reel-type movie projector system. The unit includes two film supporting flanges with a hub located therebetween. A central supporting hub is releasably connected to the hub, and fasteners releasably attach the elements together. A locking ring connects the flanges together and a flexible film winding ring surrounds the locking ring. A packing ring formed of one or more separate annular sections is located between the locking ring and the film winding ring. A handling assembly assists in moving a shipping and handling unit into position adjacent to a platter of a platter-type motion picture projector. Another form of the handling assembly includes a platter system that has the platters thereof mounted on pivots and telescoping arms to move into position to accept film from a vertically oriented film shipping and handling unit. Ramps elevate the shipping and handling unit as necessary.
