Abstract
In the case of a method of holding in position a rotatably supported thread storage surface in a thread storage and feed device, in which a group of components defining the storage surface is rotatably supported on a shaft adapted to be rotated in a housing and in which a winding-on member circulates together with the shaft, whereas magnets prevent the group of components from rotating together with the shaft, a rotational vibration damping connection is temporarily established between the housing and the group of components while the shaft is rotating In a thread storage and feed device (F), which is provided with an advance member (6) adapted to be driven such that it carries out a wobbling movement, there are arranged an externally supported rotational vibration damping member (X) and an abutment (Y) which is provided on the advance member (6). When the device (F) is equipped with a stop device including a movable stop element (23), the stop element (23) constitutes the rotational vibration damping member (X, 50).
