Abstract

A drafting arrangement for a spinning machine, comprising at least one pair of feed rollers, one pair of central rollers and a pair of withdrawal rollers, wherein the lower rollers of the drafting arrangement are configured as roller segments, which are rotated by single-motor drives, and the upper rollers are mounted in a pendulum carrier. The lower roller drive (14) at least of the pair of central rollers (21) is arranged together with its lower roller (21A) in a bearing device (15) in such a way that, after opening of the pendulum carrier (17) receiving the associated upper roller (21B), the lower roller (21A) and its drive (14) can easily be removed from the bearing device (15) in the direction of the pendulum carrier (17).
