Abstract
Apparatus for expelling reels with convoluted exposed roll films from successive film cartridges has a gate which supports a cartridge at an opening station between an axially movable mandrel and an axially movable pusher. A holder with four or more equidistant idler wheels having sharp edges is adjacent to one end of the shell of the cartridge which is located between the mandrel and the pusher to hold the shell against axial movement with the pusher when the latter is shifted axially toward the mandrel to bear upon the core of the reel in the cartridge and to expel the reel as well as one end wall of the cartridge from the shell while the mandrel transmits or is ready to transmit torque to the core in a direction to wind the film onto the core. The idler rollers are thereupon disengaged from the shell and the gate is retracted so that the shell can leave the opening station by gravity before the next cartridge enters the opening station by gravity feed.
