SPINNING MACHINE HAVING A TWISTING ELEMENT

摘要

The invention relates to a spinning machine (1), comprising a multi-cylinder drawing frame (2) for processing a fiber sliver (4), wherein the multi-cylinder drawing frame (2) comprises an intake roller pair (6) and at least two additional roller pairs (10, 12) arranged after the intake roller pair (6), which form a preliminary draft zone (7) and at least one main draft zone (8). In order to avoid faulty drafts in the multi-cylinder drawing frame (2), the multi-cylinder drawing frame (2) has a mechanical twist-producing means (9) in the preliminary draft zone (7). The invention also relates to a spinning machine with a changing device for a guide element upstream of an intake roller pair and mechanical twisting generation means. Local wear on the intake rollers can be reduced due to the changing device.
