Abstract
A drafting unit (10) for drafting discontinuous textile fibers comprises a first pair of feed rolls (12) that feed a sliver or strip (18) toward a second pair of drafting rolls (14) that draft the sliver or strip (18). The drafting unit also comprises a control device (11) to control the drafting disposed between the first pair of feed rolls (12) and the second pair of drafting rolls (14), which comprises a third pair of control rolls (20, 22), of which a first roll (20) on one side of the sliver or strip (18) and a second roll (22) on another side of the sliver or strip (18). The control rolls (20, 22) act on the sliver or strip (18) arriving from the first pair of feed rolls (12) in order to take it at a determinate speed of feed toward the second pair of drafting rolls (14).
