ABSTRACT:
An apparatus for assembling a prewind type camera having a film roll cheer with an open portion for containing an unexposed roll of film. According to the invention, a vacuum is applied to the interior of the film roll cheer at the time the prewound film roll is loaded into the film roll cheer through the open portion to maintain the film roll in a wound state after the roll is released. The vacuum remains applied until a lighttight cover is fixedly attached to the open portion of the film roll chamber thereby restraining the film roll.
