Problems solved by technology

[0005] Disadvantageous in this known solution is the fact that the individual fiber guiding belts are subject to constant wear and have mutually different manufacturing tolerances, which can affect the Evenness comes into play
Furthermore, a certain energy input is required for the movement of the fiber-guided belt, which is not negligible in terms of the operating time of the corresponding components
Finally, the replacement of the corresponding fiber guide belts is always associated with corresponding time costs, which likewise have a negative effect on the overall productivity of the corresponding textile machine

Embodiment Construction

[0039] figure 1 A side view of the roller drafting unit 1 according to the invention is shown in the rest state, ie without inserted staple fiber strands 3 . In the illustrated embodiment, the roller drafting unit 1 has an entry-side roller unit 6 , which during operation of the roller drafting unit 1 is first passed through by the supplied staple fiber strand 3 and includes the feed roller 8 And feed with the corresponding roller 9 of this feed roller. A roller assembly 7 on the outlet side is likewise provided, which correspondingly comprises a delivery roller 10 and a delivery counterroller 11 (the corresponding roller assemblies 6, 7 are mounted rotatably about the respective axis of rotation 4 and are known and for this The rollers, which are driven and loaded in a manner not described further, can obviously already bear against each other in this state by corresponding pressure loading).

[0040] Furthermore, the roller drafting unit 1 comprises an endless belt 12, as ...

Abstract

The invention relates to a roller stretching assembly of a workstation of a textile machine that processes staple fibers. The roller stretching assembly is used for stretching at least one cluster-type staple fiber strand that enters the assembly in a conveying direction. The roller stretching assembly has at least one stretching region, which is defined by a roller assembly at an entrance and a roller assembly at an exit, wherein the roller assembly at the entrance includes a feeding roller and feeding cooperation roller that work together, and the roller assembly at the exit includes a delivering roller and a delivering cooperation roller that work together. The roller stretching assembly includes an annular belt which is wound around the feeding roller and a belt guide member spaced from the feeding roller in the conveying direction so as to be guided. The annular belt is provided with at least one fastened fiber guide element that has at least part of elastic sections and that is fixed in position. During running of the roller stretching assembly, the fiber guide element presses the staple fiber strand facing the section that extending between the feeding roller and the belt guide member, and matches the contour of the annular belt on the at least part of the sections.

Description

technical field [0001] The invention relates to a roller drafting unit for a station of a textile machine, in particular a spinning machine, a roving forming machine or a knitting machine, for processing short fibers, for drawing at least one roller that enters the roller drafting unit in the direction of transport Short fiber strands in the form of bundles, wherein the roller drafting assembly has at least one drawing zone, which is defined by an inlet-side roller assembly and an outlet-side roller assembly, wherein the inlet-side roller assembly includes a feed roller and a joint therewith functioning feeding mating roller, and the roller assembly on the exit side includes the sending roller and the sending mating roller acting together with it, and wherein the roller drafting assembly includes an endless belt, which is wound around the feeding roller and is transported with the feeding roller Belt guides spaced apart in the direction and guided thereby.
