Embodiment Construction

[0017] according to Figure 1a The side view shown shows the feed area 1 , the measuring area 2 , the drafting mechanism 3 and the coiler 4 of a draw frame, for example a Trützschler TD 03 draw frame. In the feeding area, the three spinning cans 5a-5c (circular cans) of the draw frame are mounted below the sliver feed table 6 (creel) (eg Figure 1b ) in two rows; the fed slivers 7a-7c are drawn by feed rollers 8a-8c and fed into the drafting mechanism 3. Each passive feed roll 8a-8c is connected to a top roll 9a to 9c and rotates with the feed roll. Located in the area of ​​the feed table are six pairs of rollers 8, 9 ( Figure 1b ), each pair includes a top roller and a feed roller. The fiber slivers 7a-7c are lifted from the spinning cans 5a-5c and are led on the feed table 6 to the draw frame. After passing through the drafting unit 3, the attenuated sliver 7' reaches a rotating plate of the coiler and is stored in the delivery cylinder in the form of a ring. The feed t...

Abstract

A draw frame has a drawing mechanism comprising at least two pairs of rollers to which the fibre slivers are fed by a plurality of supply rollers mounted on a feed table. The fibre slivers-seen in a top view-run next to one another and towards one another laterally, and a guide element is provided between a feed table and the drawing mechanism, the lateral faces of which guide element are capableof directing the incoming fibre slivers laterally. In order to allow uniform transfer of the slivers and to enable the slivers to be oriented substantially in a plane, a sliver-guiding device is arranged across the width upstream of the guide element at a spacing therefrom at which the fibre slivers are arranged substantially in a plane, the fibre slivers passing through underneath and in contactwith the sliver-guiding device.

Description

technical field [0001] The invention relates to a device on a draw frame for feeding a fiber sliver to a drafting mechanism comprising at least two pairs of rollers, wherein the fiber sliver is fed through a plurality of feed rollers mounted on a feed table Into the drafting mechanism, the fiber slivers - as shown in the top view - run next to each other and laterally opposite each other, a guide element is arranged between the feed table and the drafting mechanism, the lateral surface of the guide element can Guiding guides the incoming fiber sliver laterally. Background technique [0002] In one disclosed device, the guide element has two lateral surfaces which are tapered relative to each other, so that the fiber sliver is guided laterally. In this structure, the outwardly arranged fiber slivers are folded over each other. The fiber slivers are raised so that - in side view - they are at different heights from each other, which impairs the even delivery of the slivers, ...
