Abstract
Apparatus for unwinding exposed customer roll films from reels immediately upon expulsion of reels from their cartridges has a composite housing which can be opened up at an unwinding station to receive a reel in the open position and to thereupon close preparatory to unwinding of the film by means of a friction wheel which is movable sideways into engagement with the outermost film convolution between the flanges of the reel at the unwinding station. A stripping device is adjacent to the inlet of a channel which is defined for the roll film by the housing in closed position, and the stripping device engages and directs the leader of the film into the channel as soon as the reel starts to rotate under the action of the friction wheel. The friction wheel and the stripping device are disposed diametrically opposite each other, and the length of the housing is less than the distance between the flanges of the reel at the unwinding station. The support for the core of the reel at the unwinding station is disengaged from the reel when the housing is closed and before the reel is driven in a direction to pay out the film.
