    摘要： This application relates to the technical field of battery manufacturing devices, and in particular, to a rewind system. The rewind system includes a conveyor assembly and a rewind apparatus. The conveyor assembly is configured to convey strips along a plurality of paths, each path being capable of conveying at least one strip. The rewind apparatus includes a drum and a plurality of shafts. The strip on each path is rewound around one of the shafts. Two adjacent shafts do not take up strips simultaneously. The drum is able to rotate around an axis of the drum. The drum is configured to switch each of the strips on different paths from one shaft onto another shaft when the drum rotates by a predetermined angle. The rewind system according to this application enable a plurality of strips to be rewound simultaneously on the rewind apparatus. The rewind system does not need to halt during the switching between shafts, so as to implement continuous rewinding and improve the rewinding efficiency significantly.

    摘要： A rewinding machine for winding web material (W) into a log (64) about a core (62), the machine comprising: a winding drum (50) rotatable about a center axis and about which the web material (W) to be wound is directed, the machine characterized by a continuous loop (52) spaced from the winding drum (50) and with the winding drum (50) defining a winding space (N) with a nip through which the core (62) is inserted and through which web material (W) is directed when winding the web material (W) about the core (62) in the winding space, the continuous loop (52) being adapted and configured to move in a direction generally opposite a direction of the winding drum (50) at the nip and to change speed relative to a speed of the winding drum (50) during winding of the web material (W) about the core (62).
