809,701. Rolling. SCHLOEMANN A.G. Aug. 21, 1956 [Aug. 22, 1955], No. 25493/56. Class 83 (4). In a method of continuous rolling in which loops are formed between the stands and controlled in size by varying the roll speeds, guides form initial loops of medium size and the speeds of the roll stands are initially set according to the speed and elongation in preceding stands. A loop guide between roll stands 1, 2, Fig. 1, has detecting means such as contact strips 12, 13 on each side of the medium-sized path 7 to control the speed of the rolls. The material is first deflected through an adjustable lead-in 3 and then tangentially engages an oppositely curved rib 7 of gradually increasing curvature which deflects the material towards an exit guide 5 and guide roller 6. Stepped ribs 8-11 engage the expanding loop and are shaped to the natural form of the free loop. Ribs 15, Fig. 2, on an adjustable cover plate 14 assist in deflecting the leading end towards the exit guide 5 and prevent whipping.
