A cassette for storage of a roll of convoluted web of photosensitive material which is to be fed to the copying station of a copying machine has a device for unwinding the web from the roll, rollers which advance selected lengths of the web into the copying station, and a mechanism which loosens or relaxes the web between the roll and the rollers so that the rollers need not overcome the inertia of the roll in order to advance selected lengths of the web from the housing of the cassette into the copying station. This can be achieved by driving the unwinding device and the rollers at different speeds so that the web forms a loop in the housing of the cassette between the outermost convolution of the roll and an outlet of the housing or by otherwise loosening the web between the roll and the outlet.
Cassette for storage of rolls of convoluted web-shaped photosensitive material and for dispensing of such material, comprising a housing having an internal chamber, means for rotatably supporting a roll of convoluted material in said chamber, and an outlet for evacuation of material from said chamber;
