Abstract
In order to prevent loops and fluff from being pushed on during the processing of non-twisted or only slightly twisted threads, the individual filaments of a thread lying next to one another are swirled by means of compressed air and are thus interlaced at more or less large intervals. If this process is carried out simultaneously with the spinning or drawing process, only large interlacing intervals can be achieved because of the high thread speed. Here, the swirling is carried out simultaneously for all the threads, after the conclusion of the thread-producing process, in the course of the warping operation which takes place relatively slowly. The threads are thus drawn from a bobbin creel (15) via breaks, thread-guide members (16), an eyelet reed (17), a fluff monitor (20), an oiling device (21) and a thread store (22) and are wound onto part warp beams (24). The swirling device (18) is preferably installed between the eyelet reed and the fluff monitor. The swirl nozzles (9) are arranged close to one another in a common housing (1, 3) and are provided with a common air-supply system. The swirling process is controlled via a regulating valve and a three-way valve (4).
Description
(54) WARPING ON SECTION WARPING BEAMS
(71) We, BAYER AKTIENGESELL
SCHAFT, a body corporate organised under the Laws of Germany of 509 Leverkusen,
Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
The invention relates to a method of and an apparatus for warping section warping beams suitable for endlessly spun, nontwisted or only slightly twisted or interlaced filament yarns.
Such yarns are produced for example with high speed spinning, stretch spinning and stretch winding and also with stretch twisting with slight protective twist. It is necessary to bring the individual, adjacent lying filaments of a thread to a single thread end in these filament yarns, in order to prevent loops and fluff from slipping in and to improve the workability of the threads. The required thread body is obtained by interlacing the filaments with compressed air in an interlacing nozzle.
The filaments of a thread are thus interlaced with each other.
With synthetic yarns, whose production essentially involves the stages of spinning, stretching and section warping, the interlacing has hitherto been carried out directly after the spinning or stretching process. Each rapid spinning, stretch spinning, or stretching position is thus equipped with an interlacing nozzle, having an air supply and a braking device. This requires a considerable technical expenditure. Besides, the thread leaves the stretching process at high speed, during the stretch spinning for example at 4000 mlmin.
However, the higher the thread speed at which the thread must be interlaced the more difficult it is to obtain sufficiently narrow interlacing intervals. Also, the expenditure with regard ‘to the production and accuracy of the nozzle and the air consumption increases considerably.
The object of the invention is to diminish the technical expenditure and the air consumption and to obtain a higher number of interlacing positions, particularly in rapidly spun and stretch spun material.
According to the invention, there is provided a method of warping section warping beams, comprising drawing threads off a bobbin creel vX thread guide devices, an eyelet reed, a slub detector, an oiling device and a thread store, wherein the threads are interlaced during the warping process, each thread being passed through a separate interlacing nozzle and each nozzle being provided with air from a common source.
For this purpose an interlacing device for the entire warp is installed in the thread path on the warping device, preferably between the eyelet reed and the slub detector. In this interlacing device each thread runs through a separate interlacing nozzle. All the nozzles of the blowing device are densely arranged in a common housing in the manner of an eyelet reed and are provided with a common air supply system. The air supply is such that the air is supplied to the nozzle housing at one or several positions via a control value and preferably a three-way value in such a way that no pressure differences can occur in the housing and thus from nozzle to nozzle. While the control value regulates the compressed air which is supplied to the nozzles constantly at a constant pressure, a constant interlacing of the threads is obtained.By adjusting the set value on the control value, the adjustment of the desired degree of interlacing can follow.
During an interruption of the warping process, produced by a slub for example, the three-way valve has the object of interrupting the air supply at the same moment in time and of clearing an opening, through which the air pressure can decrease as fast as possible in the nozzle housing, so that the threads are not interlaced exces
sively strongly at the batching position.
Therefore the valve is installed close to the housing. Its actuating control is coupled to the control of the warping machine in such a way that it stops the air supply simultaneously with the disconnection of the machine and opens a short while before starting upon the connection of the machine.
The following advantages are obtained with the invention:
A considerably better thread body is obtained. The better thread body is obtained with a lower air consumption.
During the entire thread production,
fewer disturbances occur through thread breakages and slubs, since the interlacing procedure is carried out at lower pressure, under which the individual filaments are less stressed. Furthermore, the interlacing is displaced to the end of the process for producing threads, and can therefore no longer influence the spinning process, particularly during stretch spinning and rapid spinning.
The operation of feeding the threads to the stretch spinning machine is simplified, since they are not fed from the interlacing nozzle. Thus, the device of the present invention is operated in such a way that the new threads are tied to the outgoing bobbins during the bobbins changes and it is therefore not necessary to always refeed the threads to the interlacing nozzles. Thus handling is considerably diminished overall during yarn production.
The technical expenditure is also diminished considerably, since only one more common housing and one air supply are required for the entire thread warping or the total number of nozzles (up to 2000).
In the accompanying drawings:
Figure I is a side and front elevation of an interlacing device forming part of an embodiment of the apparatus according to the invention;
Figure 2 shows a detail of the interlacing device of Figure I, partly in section; and Figure 3 is a schematic diagram of an apparatus according to the invention.
Figure 1 shows a view of the interlacing device. The interlacing device is suitably constructed in two symmetrical halves corresponding to the distribution of the threads in the warp coming from the right or from the left creel side. Each half of the device comprises essentially a flat, rectangular hollow body, the interlacing device housing (1), which joins a channel (2) on two sides as shown here or even on all four sides.
The air supplied is distributed into the nozzle housing through these channels.
They have such a cross-section that substantially no difference in pressure occurs along the nozzle housing.
The interlacing nozzles are inserted in the large area walls (3) of the nozzle housing. They are arranged in a grid, which corresponds to the supply of the threads from the creel, that is, in such a way that the threads do not have to run across each other. The compressed air required for interlacing the threads is fed to the distributing channels (2) of the nozzle housing (1) via the three-way valves (4). These valves are coupled with the control of the warping machine in such a way that they open the air supply (5)-in an adjustable time shortly before the start of the warping machine, so that the required air pressure can build up before the warping begins. Furthermore, they close the air supply immediately upon disconnection of the machine and clear the way (6) for the rapid release of the air cushion in the nozzle housing.The air is supplied addi tionally via a control valve (not shown), upon which the pressure in the nozzle housing is regulated to correspond to the pressure measuring apparatus (7). The entire interlacing device is supported in a frame (8).
Figure 2 shows the interlacing nozzles (9) and their installation in the nozzle housing.
from the creel, that is, in such a way that of a cylindrical body with an axial thread guiding channel (10) of 1.5 to 2.5 mm, preferably 2 mm, diameter. The thread guiding channel has a funnel-shaped inlet with an angle of taper of 20 to 30 and as outlet, a ceramic thread guiding eye (11) with an opening of 0.5 to 1.5 mm, preferably 1 mm diameter. The ceramic thread guiding eye prevents the threads from being fixed after the nozzle by means of an eyelet reed. A nozzle channel (12) with a diameter of 0.7 to 1.2 mm, preferably 1 mm, runs perpendicularly through the thread guiding channel. The nozzles are formed so as to be at the same time traction anchors, which take up the inner pressure on the housing walls (3). In this way the internal pressure also acts as a thrust on the nozzle packings (13). A distance box (14)l with a hole for communicating with the nozzle channel prevents the housing walls from coming together during insertion of the nozzles.
Figure 3 shows the coordination of the interlacing device in a warping device.
The threads to be drawn from bobbins in a warping creel (15) first run through the thread detector (16)l and an eyelet reed (17), on which the thread guiding eyelets are arranged in the bame grid as the inter lacing nozzles in the interlacing device.
Then they enter the interlacing device (18).
The threads are drawn in in a simple manner with a thread suction pistol. After the interlacing device, the threads pass through a reed (19) on a level with the thread, which is then wound on to a section warping beam (24) after passing a slub detector (20), an oiling device (21), and a yarn store (22) on the warping machine (23).
