Abstract (en)
[origin: EP0798407A2] When power failure occurs, a lifting drive system is operated by a simple arrangement with a power consumption smaller than that in ordinary operation until the idle rotation of a spindle drive system is approximately stopped. The draft part and spindle drive system is driven by a main motor (M) through a driving shaft (1). The lifting drive system is independent of the draft part and spindle drive system and driven by a first drive motor (19) in ordinary operation and when power failure occurs, it is driven by a second drive motor (28) which can be driven with a power consumption smaller than that of the first drive motor. Electric power is supplied to the second drive motor (28) and a controller (30) from a battery (37) in the power failure and the controller (30) controls the second drive motor (28) until the idle rotation of the spindle drive system is approximately stopped. Yarn is wound around a bobbin in the state that it does not cause a hindrance when a spinning machine is restarted and the rewinding of the yarn in a winder process is not hindered. <IMAGE>
