The three rotatable elements (4, 5, 6) are arranged rotatably on bearings (14, 15; 32, 33) connected directly or indirectly to the drive shaft (3). The middle element (4) serves essentially only for supporting the cross-wound bobbin. Planetary gears (19, 20) are provided for driving the two outer elements (5) and (6). A gearwheel (22, 24) of each of the two planetary gears (19, 20) is seated on a common shaft (27). The shaft (27) is mounted via a directionally switched coupling (28) in a web (29) which is connected to the drive shaft (3). The cross-wound bobbin is driven essentially only by the friction coverings (12, 13), having a larger outside diameter, of the outer rotatable elements (5, 6), specifically according to the non-positive connection made between their surface (17, 18) and the surface of the cross-wound bobbin. <IMAGE>
