Winding machine

Abstract

A winding machine (10) for winding and/or unwinding band-shaped or strip-like material (12) has at least one rotary plate (16), which is arranged on a pivot arm (24) and can be driven by means of at least two opposite coupling elements (20, 22), at least one coupling element (20) being associated with the rotary plate (16), and the rotary plate (16) being transferrable by means of a pivot device (30) between at least one decoupled state and at least one coupled state. Because the coupling elements (20, 22) can be positioned opposite one another in a coupling position in a sensor-based manner, this allows a coupling process which is as wear-free as possible.
