Abstract
An apparatus is provided for transporting an elongate piece of material along a predetermined path. The apparatus includes a flexible endless driven belt, for example of a plastic material, which is guided, for example by rollers along the predetermined path. Spaced clips are secured to the belt for engaging the edge region of the piece of material. The material is engaged by some of the clips at a feed station, carried along the path, and then disengaged from the clips. In a particularly advantageous application of the invention the piece of material is a length of photographic material, and the predetermined path runs through a photographic processing installation.
