摘要

IN A DEVICE (1) FOR THE CONTINUOUS STRETCH-FORMING OF A METAL STRIP (2), WHICH DEVICE (1) IN THE DIRECTION (R) OF CONVEYING THE STRIP COMPRISES AT LEAST THREE S-ROLLER UNITS (3, 4, 5, 6, 7), EACH WITH AT LEAST TWO ROLLERS (8, 9, 1O, 11, 12, 13, 14, 15,16,17), THE ROLLERS (8,9,10,11,12,13,14,15,16,17) ARE POSITIONED SUCH THAT THE METAL STRIP (2) WINDS AROUND THEM OVER A ROLLER CIRCUMFERENCE ANGLE () OF MORE THAN 180°, AND AT LEAST THE SECOND S-ROLLER UNIT (4) IN THE DIRECTION (R) OF CONVEYING THE STRIP COMPRISES TWO ROLLERS (10, 11) WHOSE DIAMETERS (D10, 011) DIFFER IN SIZE.
