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).
In a thread storage and feed device including a housing rotatably supporting a driven shaft having a thread winding-on member coupled thereto, a component group rotatably supported on said shaft and including at least one thread storage member defining a thread storage surface, a thread advance member extending obliquely relative to said shaft and driven such that it carries out a wobbling movement relative to the thread storage surface, said thread advance member projecting radially beyond said thread storage surface, and at least one magnet arranged within said component group and cooperating with at least one magnet fixedly secured to said housing to prevent said component group from rotating with said shaft, the improvement comprising:
A method of temporarily disturbing the generation, development or continuation of rotational vibrations that develop within a thread storage and feed device, said thread storage and feed device including a housing rotatably supporting a driven shaft having a thread winding-on member coupled thereto, a component group rotatably supported on said shaft and including at least one thread storage member defining a thread storage surface, a thread advance member extending obliquely relative to said shaft and driven such that it carries out a wobbling movement relative to the thread storage surface, said thread advance member projecting radially beyond said thread storage surface, and at least one magnet arranged within said component group, and cooperating with at least one magnet fixedly secured to said housing to prevent said component group from rotating with said shaft, said method comprising the steps of:
