Abstract
The winder is provided with a screen which is movable into a screening position over the lower chuck when a changeover to the upper chuck is to be performed. The screen carries a pivotally mounted guide element at the end which is pivotable into a thread guiding position to divert the thread towards the upper chuck as well as into a lowered position out of the path of the thread to screen the package on the lower chuck and particularly a trailing end of a thread from entangling with the thread on the upper chuck.
