Abstract

Primary components of the conveyor for introducing the thin strip material (2), wound into a coil (1), into the roll nip formed by the work rolls (4, 5) of a four-high rolling mill (3) are a coil cart (6) and a propelling device (7) with a clamping device (8) for seizing the strip feed end (9) of the rolling strip (2). Between a readying station (10) and an unwinding reel (11), a motor-driven coil cart (6) with a hoisting device (14) for lifting and lowering the coil (1) is movable in the strip traveling direction (a) on a track (12). In the readying station (10), backup and pinch rolls (15, 16), adjustable transversely to the strip traveling direction (a), are disposed in opposition on the two longitudinal sides of the coil cart route, for positioning the coil (1) and for threading the strip feed end (9) into a clamping device (8) attached to a transport device (7) with a drive motor, that can be propelled along a longitudinal side of the coil cart route. A clamping device (8) for seizing the strip feed end (9) at the coil (1) is attached to the propelling device (7); this clamping device can be pivoted about a pivot axis (19--19) extending transversely to the strip traveling dire…
