Abstract

Apparatus for winding the remaining unexposed frames of partly exposed films onto takeup reels in film cassettes has a socket for reception of a portion of a cassette and one or more sealing strips or cushions which prevent entry of light through the exposure window of the cassette. The gear of the takeup reel is automatically engaged by a driving gear which completes the winding of film onto the takeup reel with a force which cannot overcome the resistance of connection between the trailing end of the film and the cassette. The driving gear receives torque from a motor which is started by a microswitch in response to proper insertion of a cassette into the socket.
