Abstract
A transport device is provided which is driven by an electromotor and on which more than two bobbin supports are mounted and are movable in common such that the respective bobbin to be unwound can be brought into the required association with respect to a stationary thread eye. A thread scanning device is provided adjacent the unwound thread for detecting the thread as it jumps from the bobbin just emptied to the next bobbin. This thread scanning device is connected with the electromotor such that, when the thread scanning device responds, the motor moves the transport device to such an extent that the next bobbin is brought into the required association with respect to the stationary thread eye.
