Abstract
A cassette for winding a band-like photographic material has housing with a slot for introducing the material, a driven winding core having an endless band tensioned by a plurality of rollers and arranged to place the front of the material onto the winding core, and two lever arms pivotable about pivot axes which are parallel to the winding core axis, carrying at their ends guiding rollers and coupled with one another via the endless band, wherein one of the lever arms is connected with a spring element so that the lever arms in an initial condition assume a first position in which said endless band widely embraces the winding spool, and during further winding upon overcoming a dead point of the spring element the lever arms assume a second position in which the endless band is brought out of the region of a greatest possible spool.
