A winding device and associated method for swiveling a bobbin in the winding device during an interruption of a winding operation are provided, wherein the bobbin rests on a backing roller and is formed on a bobbin tube onto which a thread is wound. The bobbin tube is rotatably held between holders on two retaining arms mounted on a common swivel arm having a swivel axis. With force measurement unit, one of intrinsic weight of the bobbin or a force effect that acts on the retaining arms due to contact of the bobbin with the backing roller is measured. A manual force is transmitted into at least one of the retaining arms in a force direction that is determined by evaluating the force measurement unit. With a drive that is operably configured with the swivel arm, the swivel arm is swiveled in the force direction.

The present invention relates to a method and a device for swiveling a bobbin (2) in a winding device during an interruption of a winding operation. The bobbin (2) rests on a backing roller (3) and is formed on a bobbin tube (5) onto which a thread (4) is wound. The bobbin tube (5) is rotatably held between two retaining arms (6, 7) via a holder (8, 9) in each case. The two retaining arms (6, 7) are mounted on a shared swivel arm (10) having a swivel axis (11). A force effect that acts on at least one retaining arm (6) due to contact of the bobbin (2) with the backing roller (3) or the intrinsic weight of the bobbin (2) is measured by a force measurement unit (12). A force (G, H) is introduced into this retaining arm (6) by a manual transmission of force, wherein a force direction of the manually introduced force (G, H) is determined by evaluating the force measurement, and by means of a drive (13) the swivel arm (10) is swiveled corresponding to the force direction.
