ABSTRACT:
In an automatic film processing machine a special film guidance apparatus is mounted ahead of the first processing tank to determine the paths along which the various film strips are introduced into the processing machine. The film guidance apparatus has transport rollers forming at least one nip, in front of which there are vanes spaced apart across the width of the transport rollers. These vanes subdivide the space in front of the nip into several channels, with sidewalls formed by the vanes. Each individual vane can be flipped into or out of the path of the film as that film is introduced between the vanes, and then into the nip of the rollers, for conveyance to the first processing tank of the machine. The machine operator is quickly and easily able to adjust the widths of the film insertion channels to accommodate film strips of different widths, which may then be processed side-by-side through the automatic processing machine without risk of interference with each other or with machine operation. An auxiliary roller aids in unrolling the film strips from their conventional spiral configuration.
