Abstract (en)
[origin: US4527723A] Strip processing lines require tension or back tension to be applied to the strip, as the case may be. These requirements are best met by the proposed chain bridle. The recoiling of adjacent slit strips on a tension reel will result in varying rewinding speeds and tensions due to the different thickness of the individual strands. Thick strands will be rewound too tight and thin strip too loose. Therefore, the chain bridle is installed before the tension reel to keep the tension of the various strands or a wide strip at a constant value. The strip (1) is clamped between two circulating chain systems (4a,4b), one arranged below and the other above the strip passline. One chain system (4b) is fixed, the other one (4a) is adjustable. The chain segments (4) of the chain systems (4a,4b) are provided with a covering and are moved parallel to the strip (1) through support rolls (5) and guide gibs (6a) with entry and exit guide curves (6) with the latter ensuring an adequate clamping pressure of the relevant opposite chain segments (4). The segment covering (7) may consist of an elastic coating (11) provided with additional shapes or profiled surfaces (12).
