ABSTRACT Apparatus For Pulling Forward or Holding Back Moving Metal Strips An apparatus for exerting a forward or rearward drag on a moving metal strip (9), for use in particular with narrow metal strips which are to be wound up together side by side and which are to have separate rearward braking drags applied to them, comprises two endless conveyor chain systems (3, 4) driven by chain wheels (23). Each of the chains of the systems is formed by a series of pivotally interconnected roller units (7) which are guided by guides (l3) along a straight drag-applying zone (12) where the strip (9) is clamped between the units (7) of the systems (3, 4) and has a drag (8) applied to it. Further guide bars (17) are proviaed remote from the zone Sl2) and these bars tl7) together with the chain wheels 114) and guide segments (15, 16) guide each ronveyor chain (3, 4) along a path which is curved along its whole extent except where it passes through the straight drag-applying zone (12). In this way abrupt changes in direction of the chains t3, 4) are largely avoided and rattling and thus wear of, and noise from, the chains is reduced.
