Abstract: To allow the gap between a pair of belts and the output pair of rollers of a drafting frame for a textile machine to be reduced, the sliver compaction funnel which is disposed at the inlet side of the nip of the output pair of rollers is mounted on an arm which extends alongside the upper rollers or upper belt. The funnel can be mounted on two arms which straddle the ends of the upper roller or upper belt.

Abstract: Fiber material to be spun is presented to drafting equipment in the form of a fiber sliver and is subjected to pre-stretching and main stretching in such drafting equipment. While being stretched, the fiber sliver is gathered together to a minimum width which amounts to at least 1.5 times the diameter of a torsion device to be used with the sliver. After being thus gathered together, the fiber sliver is not further gathered together before having torsion imparted thereto while such diameter is maintained. The width of a condenser situated upstream from the main stretching field amounts here to at least 1.5 times the diameter of a pneumatic torsion device situated downstream from such field. The injector component and torsion component of such torsion device are of identical diameter, from their intake opening to their outlet opening. In this way, hairy and soft yarns, similar to ring yarn, are produced.

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.

Abstract: Draft apparatus for use with a pneumatic high speed spinning frame. At least one pair of sliver compressing member are disposed on the sliver path. One of the sliver compressing members has a circumferential recessed groove for receiving the sliver and the other sliver compressing members has a circumferential rib adapted to be fitted into the recessed groove.

Abstract: A drafting arrangement including a collector means suitably utilized for fasciated yarn spinning. The collector means in the shape of a hollow shell is disposed between a preceding draft means such as a pair of front rollers and the post draft means such as a pair of a aprons, in such a manner that a front surface of the collector means confronts a rearward surface of the preceding draft means and, on the other hand, a rear surface of the collector means confronts a front surface of the post draft means with a predetermined clearance. By this construction, a concomitant air stream accompanying rotation of the draft means is effectively expelled out of the fiber passage and stable drafting can be accomplished.

Abstract: A spinning frame of the type having a main drafting zone through which two fiber bands move in spaced parallel relation for subsequent twisting into a single yarn is provided with a first pair of rollers located at the entrance to the main drafting zone, a second pair of rollers located at the exit of the main drafting zone, a pair of endless leather tapes extending about a roller in each of the first and second pair of rollers, and a third pair of rollers for delivering two fiber bands from the main drafting zone to a suitable twisting device.
