WARPING BEAMS
Abstract of the Disclosure The invention relates to a method for warping on section warping beams comprising drawing threads off a bobbin creel via thread guide devices, a loop reed, a slub detector, an oiling device and a thread store, wherein the threads arc interlaced during the warping process.
Description
~740~8 The invention relates to a method and an apparatus for warping on section warplng 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 spLnning and stretch winding and also with stretch twisting with slight protective twist. It is necessary to bring the individual, ad;acent 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 inter-lacing the rilaments with compre~sed air in an interlacing nozzle. The iilaments of a thread a~ thus interwoven with each other in more or less large interva7s.
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 m/min.
However, the higher the thread speed at which the thread must be interlaced the more difricult it is to obtain sufficiently narrow interlacing intervals. Also, the expenditure with regard to the production and accuracy Or the nozzle and the air consumption increase~ considerably.
The object of the lnventiion is to diminish the technical expenditure and the air consumption and to obtain a higher number of interlacing positione, particularly in ,~
.
, ~5~74~318 rapidly spun and stretch spun material.
According to the invention, there is provided a method for warping on section warping beams, comprising drawing threads off a bobbin creel via thread guide devices, a loop reed, a slub detector, an oiling davice and a thread store, wherein the threads are interlaced during the warping process.
For this purpose an interlacing device for the entire thread warp i9 installed in the thread path on the warping device, preferably between the loop 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 arra~ged in a common housing in the manner of a loop reed and are provided with a common air supply system.
The air supply ensues in such a way that the air is supplied to the nozzle housing on one or several positions via a control valve and a three-way valve in such a way that no pressure differences can occur in the housing and thus from nozzle to nozzle. While the control valve regulates the compressed air which iB supplied to the nozzles constantly at a constant pressure, a constant interlacing of the threads i9 obtained. By adjusting the set value on the control value, the adjustmcnt of the desired thread end can follow. During an interruption of the warping process, produced by a slub for example~ the three-way valve has the object of ,, . .. _ .. . .. _ .. .... , .. ....... ... _ _ .. _ _ .
1~74~3188 interruptin~ the air supply at the same moment in time and Or clearing an openin~, throu~h which the air pressure can decrease ~s fast as possible in the nozzle housing, so that the threads are not interlaced excessi~ely strongly at the batchin~ position. Therefore the valve i9 in~talled close to the housin6 Its actuating control is coupled to the control of the warpin~ 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 connection oi the machine.
The following advantages are obtained with the invention:
A considerably better thread body is obtained. The better thre~d body is obtained with a lower air consumption.
During the entire thread production, fewer disturbances occur through thread breaka~es and slubs, since the interlacing proce~ure follow~ under lower pressure, under which the individual filament~ are less stres~ed. Furthermore, it is displaced to the end of the process for producing threads.
It can no longer influence the spinning process, particularly during stretch spinning and rapid spinning.
Tlle operation o~ reeding the threads to the ~tretch spinning machine is simplified, ~ince they are not ~ed from the interlacing nozzle. This procedure must also follow during each change of bobbins or at least after each cleaning o~ the spinning nozzles. According to the invention, however~
the threads are only seldom to be drawn in to the interlacing device, since the new thread is tied to the outgoing bobbin during a bobbin change on the warping device. Thus handling i~ considerably dlminished overall during yarn production.
The technical expenditure is also diminished considerably, since only one more common housing and one air supply are .. ...

Figure I is a side and front elevation of an interlacing device forming part of an embodiment of the apparatur~ according to the invention;
Figure 2 shows a detail of the interlacing device of Figure I, partly in section; and Figure 3 i~ a schematic dia-gram of an apparatus according to the invention.
Figure l 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 (l), 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 th~t ~ubstantially no difference ln pressure occurs along the nozzle housing.
The interlacing nozzles are inserted in the large ~rea walls (3) of the nozzle housing. They are arranged in a grid, which correspond~ to the supply of the threads from the creel, that i9, in such a way that the threads do not have to run across each other. The compressed air required ior inter-lacing the threads i~ fed to the distributing channels (2) Or the nozzle housing (l) via the three-way valves (4).
These valve~ are coupled with the control of the warping 1074(~88 machine in such a way that they release the air ~upply (5) -in an adjustable time - shortly ~efore the start of the warp-ing machine, so that the required air pressure can build up before the thread warp 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 supply follows additionally via a control valve, upon which the pressure in the nozzle housing is regulated to correspond to the pressure mea~uring apparatus (7). The entire interlacing device i8 supported in a frame (~).
Figure 2 shows the interlacing nozzles (9) and their installation in the nozzle housing. The interlacing nozzles consist essentially of a cylindrical body with an axial thread guiding channel (10) of 1.5 to 2.5 mm, pre~erably 2 mm, diameter. The thread guiding channel has a funnel-shaped inlet with an angle of taper o~ 20 to 30 and a9 ou~let, 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 saves the threads from being fixed behind the nozzle by an eye 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 at the same time as traction rotors, which take up the inner pres~ure 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) with a hole for releasing the nozzle channel prevents the housing wall~ ~rom coming together during insertion Or the nozzles.
~07~08~3 Figure 3 shows the coordination of the interlacing device in a warping device~ The threàds to be drawn from bobbins in a warping creel (15) first run through the thread detector (16) and a loop reed (17), on which the thread guiding loops are arranged in the same grid as the interlacing nozzles in the interlacing device. Then they enter the interlacing device (18). The threads are drawn in in a simple manner with a thread eye pistol. After the interlacing device, the threads are joined together in an inlet reed (19) on a level wlth the thread warp, 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).
Such yarns are produced for example with high speed spinning, stretch spLnning and stretch winding and also with stretch twisting with slight protective twist. It is necessary to bring the individual, ad;acent 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.
