Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
An arrangement for transporting strip-shaped material, particularly photographic paper, comprising a conveyor belt; means for holding the strip-shaped material, including a one-piece elongated holding element extending 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 clampingly engaging the strip-shaped material, said sections having effective lengths at least equal to the width of the strip-shaped material and two of said sections having free ends; and means for attaching said holding element to said conveyor belt, including two discrete brackets each affixed to a different one of said free ends and both separably connected to said conveyor belt.
Claim 2
Dependent Claim
112 words
An arrangement for transporting strip-shaped material, particularly photographic paper, comprising a conveyor belt; means for holding the strip-shaped material, including a one-piece elongated holding element extending 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 clampingly engaging the strip-shaped material, said sections having effective lengths at least equal to the width of the strip-shaped material and two of said sections having free ends; and means for attaching said holding element to said conveyor belt, including two discrete brackets each affixed to a different one of said free ends and both separably connected to said conveyor belt.
Claim 3
Dependent Claim
19 words
An arrangement as defined in claim 1, wherein at least said sections of said holding element have round cross-sections.
Claim 4
Dependent Claim
21 words
An arrangement as defined in claim 1, wherein each of said brackets has a substantially C-shaped configuration and embraces said belt.
Claim 5
Dependent Claim
32 words
An arrangement as defined in claim 1, wherein said free ends extend substantially at right angles to the remainder of the respective sections, said brackets being welded to the respective free ends.
Claim 6
Dependent Claim
48 words
An arrangement as defined in claim 4, wherein said sections are disposed substantially in a common plane and said two sections are the outer sections of said four sections, the inner two sections extending along a stepped course between said brackets at one side of said conveyor belt.
Claim 7
Dependent Claim
49 words
An arrangement as defined in claim 1, wherein said sections are disposed substantially in a common plane and further include two inner sections which abut one another, each of said inner sections abutting one of said first mentioned two sections in the absence of strip-shaped material in said spaces.
Claim 8
Dependent Claim
47 words
An arrangement as defined in claim 1, wherein said holding element includes turn regions interconnecting said sections, said regions having relatively small radii of curvature and extending along arcs exceeding 180° in unstressed condition of said holding element to resiliently press the neighboring sections against one another.
