ABSTRACT:
A drafting roller arrangement for spinning machines is disclosed having at least three pairs of rollers forming successive drafting zones in the conveying direction of the sliver and having a sliver stopping device assigned to the first pair of rollers that can be triggered by a disturbance. In front of the last drafting zone, a sliver condenser having guide surfaces narrowingly tapering in the conveying direction of the sliver is arranged. The sliver condenser is provided with a threading slot extending in the conveying direction of the sliver and is held by means of a holding device in such a way that it can be moved out of the drafting zone transversely to the conveying direction toward the side facing away from the threading slot. This arrangement accommodates restarting of the drafting arrangement without the sliver condenser interfering with the sliver supplied to the last drafting zone.
