Known devices for winding up material webs, in particular paper or cardboard webs, on winding tubes, have longitudinal cutters for separating the ma- terial web (1) into individual webs and winding sta- tions (9, 10) arranged on both sides of a driven back- up roll (8). The winding stations have two bearing elements (11, 12) movable in a direction parallel to the back-up roll and upon which is secured a guiding head (15, 16) with a rotative drive (17, 18) that can move in the direction of the back-up roll and pene- trate in the winding tubes. In order to be able to ad- just without problems the winding stations (9, 10) to various formats, in particular very narrow formats, li- quid-cooled electric motors are used as rotative drives (17, 18) for the guiding heads (15, 16).
