In a device on a draw frame having a drafting system for textile fibre slivers with weighting of the upper rolls (1, 2, 3, 4) of the drafting system which comprises roll pairs arranged one behind the other, the pairs having lower and upper rolls (III, 4). The rotating journals (4.2) at the ends of the upper roll (4) are mounted by means of bearing elements (22). The bearing elements (22) each have at least one rolling-element bearings having an immovable outer housing (22.1) and an internal rotational body (22.21). In order to provide a structurally simple way in which the bearing housings (22.1) can be mounted on or removed from the presser roll in a simple, quick and reliable manner, the bearing elements (22) are in the form of rolling-element bearings (37) and there is a coupling (43) between the journal (4.2) and the rotational body (22.21) |
