Abstract
A winding device, in particular for conical bobbins, including; a rotatable friction roller which rotates a bobbin through friction. The friction roller consists of several rotatable elements installed next to each other which are mounted on a shaft. One of the elements is connected non-rotatably with the shaft, the other elements of the friction roller are freely rotatable on the shaft and are connected to each other by a differential gear transmission. The differential gear transmission is in the form of a friction wheel transmission. The axes of the friction wheel transmission are at a perpendicular to the shaft.
