ABSTRACT:
An arrangement for transporting strip-shaped material, particularly photographic paper, includes a one-piece elongated holding element which extends along a triple-turn hairpin course to form four holding sections which are substantially parallel to one another and define with each other three spaces for strip-shaped material. Two brackets which are welded to the end portions of the two outer sections of the holding element and are bent at right angle to the remainder of the respective outer sections support the holding element on a conveyor belt for travel therewith. The four sections of the holding element resiliently contact one another to clamp the strip-shaped material therebetween when such strip-shaped material is received between neighboring sections.
