Abstract
A draw frame for textile fiber slivers has a drawing system of successively arranged assemblies of rollers comprising a bottom and a top roller, in which, during operation, the top rollers are pressed against the bottom rollers by weighted pressing devices. When operation is suspended, the bearings of the top rollers are relieved of the weighting by the pressing devices. On interruption to continuous operation the top output roller or the top output rollers is/are capable of being relieved of loading in such a way that no or only slight pressure is exerted on the fiber slivers. To avoid or reduce undesirable formation of windings in a simple manner, resiliently loaded elements that lift the top roller bearings after the pressing devices have been relieved of loading are associated with the bearings of at least one top roller.
