In a method for opening a drafting arrangement (1) with a plurality of pairs of rollers for drawing a sliver (2), the fiber tape (2) between a pair of transport rollers (6) and an at least one input and a pair of output rollers (10, 12), a preferably input, at least one central and a pair of output rollers (10, 11, 12) comprising a drafting unit (1) taut, wherein each roller pair of the drafting unit (1) has at least one upper and one lower roll. Before opening of at least the input and / or middle roller pair (10, 11) of the drafting arrangement (1), the tension of the sliver (2) between the transport roller pair (6) and the drafting unit (1) is reduced, in particular released. In a corresponding drafting arrangement by means of a mechanical or electrical coupling or ; Control prior to the opening of at least the input and / or middle roller pair (10, 11) of the drafting arrangement (1), the tension of the sliver (2) between the transport roller pair (6) and the drafting unit (1) is reduced, in particular released. |
