ABSTRACT:
A strip of exposed film which issues from a developing machine is convoluted onto the core of a horizontal takeup reel whose flange or flanges rest on the peripheral surface of a horizontal roller which is driven to rotate the reel in a direction to convolute the strip. The strip is braked by a tensioning device between the developing machine and the reel, and the latter is thereby maintained in a first position of abutment with the concave internal surface of a first locating device and in contact with the driven roller. A spring-biased lever urges the reel to a second position in which the reel is out of contact with the roller and abuts against the concave inner side of a second locating device. The lever is free to move the reel sideways and to the second position as soon as the action of the tensioning device upon the strip is terminated, namely, as soon as the trailing end of the strip advances beyond the tensioning device. The first locating device is mounted between the second locating device and the tensioning device, and the two locating devices define a gap for the upper portion of the roller. The latter is nearer to the first than to the second locating device and its upper portion is engaged by the flange or flanges of the reel when the latter is held in the first position.
