摘要

Device on a draw frame (S) for textile fiber slivers (5) with loading of top rollers (1 to 4) of a drafting device (1 to 4; I to III) of the draw frame (S), where • the drafting device (1 to 4; I to III ) consists of roller pairs (1, 2 / I, 3 / II, 4 / III) arranged one behind the other with lower roller (I to III) and upper roller (1 to 4), in which the upper rollers (1 to 4) are subjected to stressed pressure elements during operation (91 to 94, 9a1, 9a2, 9d1) are pressed in pressure arms (11a to 11d) against a respective associated one of the lower rollers (I to III), • each upper roller (1 to 4) has two pressure elements (91 to 94, 9a1, 9a2, 9d1 ) are assigned to a respective receiving element (13a1, 13a2; 32a, 32b), • a loading device formed by means of the pressure elements (91 to 94, 9a1, 9a2, 9d1) is removably arranged, • the pressure arms (11a to 11d) with the pressure elements ( 91 to 94, 9a1, 9a2; 9d1) are rotatable or pivotable about a rotary or pivot bearing (10) and • the pressure elements (91 to 94, 9a1, 9a2; 9d1) by a support element ent (12a, 12d) are connected to one another, characterized in that • each receiving element (13a1, 13a2; 32b, 39) is attached to a lower end of the associated pressure element (91 to 94, 9a1, 9a2, 9d1) facing the associated upper roller (1-4) and • a bearing (22a) on each receiving element (13a1, 13a2; 32b, 39) ) is attached, in which a respective one of the roll journals (4a) of the associated top roll (4) engages.
