  • Publication number: 20210146420
    Abstract: The invention relates to a band or strip guiding device (7) for guiding metal bands (B1 to B6) in a band processing system (1) between an inlet conveying section (3) and an outlet conveying section (5). The band guiding device (7) comprises two partial conveying sections (13, 15) arranged one above the other, two switch devices (17, 19) for selectively connecting the inlet conveying section (3) and the outlet conveying section (5) to one of the two partial conveying sections (13, 15), and for each partial conveying section (13, 15) an inlet-side separating device (21, 23) for severing a band (B1 to B6) arranged in the partial conveying section (13, 15), and an outlet-side separating device (22, 24) for severing a band (B1 to B6) arranged in the partial conveying section (13, 15) on the outlet side. Each switch device (17, 19) has a movable clamping device (31, 32) for fixing a band (B1 to B6) in the switch device (17, 19).

  • Patent number: 9776226
    Abstract: A rolling system, particularly a cold-rolling system for cold-rolling a metal strip (2): having at least one cold-rolling stand (1) an unwinding device (3) upstream of the cold-rolling stand (1), a unit (10) connected between the unwinding device (3) and the cold-rolling stand (1), including at least three rolls (6, 7, 8) each rotationally driven about a rotational axis (6A, 7A, 8A). Each roll (6, 7, 8) can be adjusted individually or together in the direction of the respective rotational axis (6A, 7A, 8A) and in a direction transverse to the rotational axis (6A, 7A, 8A) by a driving and adjusting device (11).

  • Patent number: 9592987
    Abstract: A strip deflection device (1) for deflecting a strip (2), in particular a metal strip, at an angle: at least one deflecting cylinder (3) around which the strip (2) can be deflected by a deflection angle (7) while maintaining strip tension. The angle is defined by the inlet direction (14) and the outlet direction (15) of the strip (2). Rollers (20) on the circumference of the deflection cylinder (3), form bearing faces of equal height for the strip (2) along a wrap around the cylinder. The deflection cylinder (3) can be adjusted between a first (31) and a second operating position (32) preferably perpendicular by an adjusting device (16). Each operating position (31, 32) is associated with a respective arrangement (10, 11) of the rollers (20) and the rollers in that arrangement (10, 11) are oriented in a direction that corresponds to the wrap around the cylinder.
