Abstract
An apparatus on a draw frame for textile fiber slivers has a drawing system having weighting of the top rollers of successively arranged pairs of rollers comprising a bottom and a top roller. During operation, the top rollers are pressed against the bottom rollers by weighted pressure elements in pressure arms. Two pressure elements with a common holding element are associated with each top roller and the weighting device is removable. To improve the said apparatus, a pressure element is rotatably or pivotally mounted at a center of rotation or a pivot bearing and the pressure elements are connected with one another by a supporting element.
