A feeding mechanism for supplying elongated strips of material, such as photographic print paper and the like, in a tension-free state by use of a slack loop of said material, the size of which varies in response to the demands of a processing machine. Said loop actuates a switch for energizing and deenergizing a drive mechanism for supplying said loop from a supply roll so that the size of the slack loop directly controls the supply mechanism.
