Abstract

1,220,775. Rolling strip. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (St. Chamond Firminy, St. Etienne, Jacob- Holtzer). 18 April, 1969, No. 19873/69. Headings B3A and B3M. Thin strip is continuously cold rolled in two stages; in the first, the strip is rolled to a constant thickness, and in the second the strip is rolled in several passes to give it a constant elongation. Strip from a coil 1, after passing a welding unit 2 for joining adjacent strip ends and a loop pit 4, is rolled to constant thickness in a stand 7. The strip is then rolled with constant elongation in a series of stands 9 before passing from a loop pit 10 and a cutter 11, to a coiler 12. The strip may then be annealed and rolled through a further series of stands 9. Each stand 9 includes pairs 13 and 14 of tension rollers on its input and output sides, the rollers being mechanically connected to maintain a constant speed ratio between the pairs of rollers. As seen in plan, Fig. 4, the rollers 13a and 14a are driven from a common motor 25 through gearing 15. The speed ratio between the rollers is adjustable by variable speed gearing 25. The motor 26 drives the rolls of stand 7.
