Abstract

PURPOSE: To properly control yarns in all paths through a texturing machine by converging the yarn paths of plural yarns at a fluid jetting means at a specific angle to each other. CONSTITUTION: Yarn feed and drawing means 19, 20 and a fluid jetting device 24 are disposed in the manner that the yarns 15, 16 are fed from the former to the latter at a space apart each along an essentially straight path. These straight paths each converge inside the fluid jetting device 24, converging at an angle α of between 70-50 deg., for example at 65 deg., and ensuring the optimum control of the yarns in a low tension region.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yarn texturing machine. More specifically, the present invention relates to a textile machine that processes yarn using a jet fluid.

[Conventional technology]

- or a plurality of yarns, either singly or in parallel or wound with a core yarn in the form of threads, are fed to a fluid jetting device in which the filaments of the yarn are looped by a turbulent fluid; BACKGROUND OF THE INVENTION Textile machines are known that can be formed to produce bulky single or composite yarns suitable for a variety of textile applications.

In order to perform this process efficiently, a yarn wetting device may be provided immediately upstream of the fluid jetting device, and this fluid jetting device acts on some or all of the yarns, and in such a case, The yarn wetting device and the fluid ejection device are conventionally housed in a common housing or "jet box."

In order to ensure that the yarn is processed in an acceptable way, any yarn running through the yarn wetting device should not be exposed to any of the yarns running through the yarn wetting device in a parallel arrangement, more preferably with the core yarn and the winding yarn with the yarn. It is necessary to keep it away from other yarns until they enter the fluid ejecting device together.

If this is not done, entanglement of the filaments constituting the yarn may occur upstream of the fluid ejection device, thereby inhibiting or hindering the processing of the yarn.

To prevent such prior entanglement, it is common to provide a two-thread guide on the jet box prosthesis and the body of the fluid ejection device. These guides keep the yarn paths apart and change the direction of yarn travel, thereby increasing yarn tension in the yarn running around the guides.

Therefore, the thread tension just before the inlet of the jet box is much smaller than the thread tension at the inlet of the fluid injection device.

Since the tensioning effect of the fluid jet device decreases as the yarn processing speed increases, when the yarn tension upstream of the jet box artificial guide decreases to a level that results in an unstable yarn path, the yarn processing speed increases. This is the upper limit.

To avoid such problems, feeding the two threads from a feeding means to an air injection device along spaced apart but converging straight thread paths is disclosed, for example, in US Pat. No. 4,608,814. Known from the specification.

Such an arrangement eliminates variations in yarn tension along the yarn path. The yarn separation angle in this prior document is specified to preferably range from 8'' to 25''.

[Problem to be solved by the invention]

However, at current high processing speeds, yarn tension upstream of the air injection device is low and it has been found that the arrangement described above can result in yarn entanglement.

Furthermore, it has been found that by increasing the separation angle of the converging yarns too much, the quality of the resulting textured yarn is reduced.

[Purpose of the invention]

SUMMARY OF THE INVENTION The object of the invention is to provide a yarn processing machine which makes it possible to eliminate the above-mentioned problems completely or at least to a considerable extent, by means of which the yarn can be properly distributed over the entire path through the processing machine. The goal is to provide something that can be controlled.
