DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for producing a short warp according to the preamble of claim 1 and a single yarn (monofilament) for carrying out this method according to the preamble of claim 4. )).

[0002]

BACKGROUND OF THE INVENTION Such a method and such a partial warper are described in European Patent Publication No.
It is known from the publication 0 375 480. In this known device, a warping drum carries two cutting rods for cutting a selected yarn on one peripheral flat portion and three lead rods forming two twills on opposite peripheral peripheral portions. It is carried on a flat part. When the shaping drum has been wound with the desired design, the yarn sheet is rewound onto the winding beam while simultaneously rotating the warping drum. When this rewinding is completed, a warping operation for the next warp can be started to rewind the warp on the winding beam into a commercially available warp beam.

[0003] In this way, very well designed short warps can be produced from wool (wool yarn). One twill is generated near the beginning and the end of the yarn sheet. The connection to the warp beam, or directly to the loom, is made using the upper twill. in this case,
Low loss of wool material.

However, treating cotton yarns in the same way encounters technical difficulties. This is because, for example, in order to improve the properties of the single yarn during the subsequent weaving process (improve the protection and resistance (slipperiness) of the yarn against external influences; improve the uniformity and strength of the single yarn in the warp). In addition, cotton yarns must in most cases be wet glued. Conventionally, single yarns are glued before being fed to a partial warper. For this reason, an expensive sizing machine (sizing machine) that significantly reduces the feed speed is required. In addition, cotton yarns have reduced mobility properties required for warping operations.

An object of the present invention is to provide a method for producing a short warp consisting of a single yarn such as cotton, which can be additionally glued after forming a yarn sheet, and to carry out this method.
An object of the present invention is to provide a partial warping machine for a short warp made of a single yarn .

[0006]

This object is achieved according to the invention by the features of claim 1. The short warp made of a single yarn such as cotton produced in this way is used when rewinding from a warp beam to another warp beam, using a commercially available sizing machine (sizing machine), for example, "Size O ( Gluing can be performed by a sizing machine of "O) -matic type". The sizing machine has one or two size boxes, a pair of squeezing rollers provided at the subsequent stage, and a multi-path / cylinder type drying device. Such a sizing machine
Conventionally, a plurality of partial sheets have been inserted from a warping beam creel. At the outlet side, these partial sheets are assembled in a beam unwinder into one thread sheet or warp.

According to the invention, two measures are taken together. In other words, on the other hand, when all the yarns are separated into a plurality of partial sheets that are dried on different paths during the gluing, it is possible to give the yarns in the respective partial sheets a mutual distance that makes gluing impossible. . On the other hand, the leading portion and the trailing portion keep the separation of the partial sheet while maintaining the leading end of the yarn sheet pulled out of the warp beam and the leading yarn sheet pulled out of the warp beam that has been wound back and ended before. It is possible to connect to the terminal end, so that the partial sheet is pulled by the leading yarn sheet through the drying section. The partial sheet, the leading section and the trailing section can be automatically generated during the aging of the short warp.

[0008] A partial warping machine for a short warp comprising a single yarn for carrying out the above-mentioned method for producing a short warp is characterized by what is described in claim 4. That is, the arrangement of the cutting rod and the release rod and the use of the dividing rod are combined with the selected control system (the first or second program in the embodiment), and the partial sheet, the leading portion, and the following portion are used. Results in generation. The warp beam formed by the short warp partial warping machine can be placed directly before the sizing machine.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The lengths specified in claims 2 and 3 of the preceding section and the following section are long enough to pass through a normal drying section, and the length of the normal section is 2.25 m. This is a preferred embodiment because it can be manufactured on a warping drum having a diameter.

[0010] The configuration of claim 5 is particularly suitable for achieving the desired lengths of the leading part and the trailing part.

When five to seven dividing rods are used as in claim 6, a relatively large distance (gap) between adjacent yarns in each partial sheet to promote drying.
Is obtained.

When two cutting rods are used, two different cutting steps can be executed (performed).

With the configuration according to the eighth aspect, a partial warping machine which can be versatilely implemented and is suitable for not only the treatment of cotton yarn but also the treatment of wool yarn can be obtained.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the preferred embodiments shown in the drawings.

FIG. 1 is a view schematically showing a configuration of a partial warping machine 1 for a short warp made of a single yarn . This partial warping machine 1
Has a warping drum 2, and the warping drum 2 has a conveyor (an axial conveyor and an axial conveyor) extending in an axial direction (rotation support axis direction) on two peripheral surface portions 3 and 4 (with the center therebetween) facing each other. 5). A rotating body 6 provided on one front face (the left front face in FIG. 1) of the warping drum 2 is driven by an electric motor 7. The rotating body 6 carries a yarn feeder 8. The yarn feeder 8 pulls out the single yarn 9 from the creel yarn 10 and feeds it onto the axial conveyor 5. At that time, the warping drum 2 is fixed with a torsional rigidity so as not to rotate, and only the conveying portion of the axial conveyor 5 is the other front side of the warping drum 2 (the right front side in FIG. 1).
Is performed at a slow speed in the direction of, so that a single-layer yarn sheet orbiting on the warping drum 2 is generated on the warping drum. A yarn selection device 11 is provided for design, and is controlled by a control device 12. Here, another yarn 9 'is supplied from another creel yarn 10'. When the yarn feeder 8 passes by the yarn selection device 11 on the basis of the design program, the yarn 9 is transferred to another yarn 9 ′.
Replace with The control device 12 has an input unit 13 and the input unit
Via 13 a desired program can be entered or a stored program can be called up. The illustrated three output portions 14 are provided with cutting rods illustrated in FIGS.
An output is provided to control to selectively form a yarn path above or below TT1, TT2, lead rods FK1, FK2, and dividing rods ST1 to ST5.

As shown in FIG. 2, the beam rewinding equipment 15 following the partial warper 1 comprises a winding beam 16 and a warp beam 17.
And The first beam rewinding operation of the automatically warped warp from the warping drum 2 to the take-up beam 16 is schematically illustrated in FIG.

The yarn sheet 19 is pulled out from the warping drum 2 in a direction opposite to the winding operation by the yarn supplying device 8. That is, in the case of the yarn sheet 19 shown in FIG. 3A, the yarn sheet start end 20 is the yarn end to be wound, and the yarn sheet end 21 is the yarn start end to be wound. The thread sheet 19 has three parts. That is, the original warp yarn 22 between the twill 23 and the separation point 24, the leading portion 25 between the separation point 24 and the yarn sheet start end 20, and the yarn sheet end 21
And a trailing part 26 between the aya 23.

Second from the take-up beam 16 to the warp beam 17
The beam rewinding operation is schematically shown in FIG. In this state, the leading portion 25 and the separation portion 24 followed by the partial sheet are located on the warp beam 17 on the warped beam 17 on which the winding has been completed, so that the separation portion 24 follows the front side. This warp beam 17 can be placed as it is in front of the sizing machine.

FIGS. 4 and 5 show the above-described configuration and operation mode more precisely and in detail. Warping drum 2
In addition to the peripheral surface portions 3 and 4, two peripheral flat portions (referred to as flat surface portions formed on the outer periphery of the warping drum 2) 27 and 28 respectively disposed between them are provided. Have. Two cutting rods TT1 and TT2 that can cut the selected yarn,
Leeds rods FK1 and FK2 which are useful for forming the traverse are sequentially provided on the peripheral flat portion 27. For example, one cutting rod TT1 acts as a cutting rod and the other cutting rod TT2 acts as a fixed rod. In the peripheral flat portion 28, five dividing rods ST1 to ST5 are sequentially arranged, and the yarns 9 spaced apart from each other are partially sheeted by these dividing rods ST1 to ST5. It can be separated from the rest of the yarn as 20a-20f). FIG. 6 conceptually shows a state in which a partial sheet is formed by being separated from the remaining yarn sheets by dividing rods ST1 to ST5.

The yarn path is determined by guide elements (not shown) provided on each of the rods, and these guide elements are controlled and operated by the controller 12. When the guide element is in the course of the yarn 9 supplied by the yarn feeder 8, the yarn is placed on the upper side of the rod; otherwise, the lower side of the rod when there is no guide element in the course. To be placed.

FIG. 5 shows the warping drum 2 as indicated by an arrow in FIG.
The yarn path of each of the six repeats (winding) when rotating in the direction indicated by 20 is shown. In a normal order, each repeat consists of about 1000 (books). Here, at the time of winding, each of the six yarns 9 has five winding yarns between its start end 30 and end end 31.
It is wound on the warping drum 2 by 32 to 36 and then the thread sheet 19
Is drawn in the direction of arrow 29 as an example. The first winding thread 32 (later trailing portion) is below all the rods except the cutting rod TT1. The second winding 33 (the part where the twill is formed) is alternately above or below the lead rods FK1 and FK2, above the cutting rod TT2, and below all other rods. Volume 3 (Volume 31 to 3n
Winding; n is any number determined by the length of the short thread) Thread 34
(The part that determines the length of the short length) is placed above the cutting rod TT2, the lead rods FK1 and FK2, and below all other rods. The fourth winding thread 35 (the part to be glued) is a cutting rod
TT2, above the lead rods FK1, FK2, and the cutting rod TT1
And the yarn is fed into an area (part) to be glued according to the combination of the dividing rods ST1 to ST5.
The fifth winding thread 36 (the later leading part) is below the cutting rod TT1,
And on top of all other rods.

As apparent from this, the thread sheet 19
When the arrow is pulled in the direction of arrow 29, the leading portion 25 first occurs,
Since the leading portion 25 is the fifth winding thread 36, the portion shown in FIG.
It is equal to the length of 25 'plus one winding of the fifth winding thread 36. Since the trailing portion 26 is the first winding thread 32, it is equal to the length of the portion 26 'in FIG. 5 plus one winding of the first winding thread 32. The remaining winding yarn is the original warp 22 portion, to which the portion 22 'in FIG. 5 has been added.

The fourth winding thread 35 of each thread 9 is a lead rod FK1, FK.
The twill is formed by being crossed by two. Actually, among the six yarns 9 arranged side by side, each of the second winding yarns 33 whose number of windings is determined by the desired short length is set.
However, the yarn is supplied by another combination of the five dividing rods ST1 to ST5. This means that, for example, when there are 1000 repeats (1000), 1000 single yarns are placed on each dividing rod. Also in this case, each dividing rod separates from the remaining thread sheet to form a partial sheet.

In this way, the auxiliary measures necessary for the gluing of the thread sheets, namely the separation into partial sheets and the formation of the leading and trailing parts, are carried out on a partial warper.
Separation into partial sheets is essential so that the yarns can be completely dried at a distance from one another in the sizing machine. It is desirable to form a glued portion with 5 to 7 dividing rods corresponding to the number of yarns in the warp and the yarn density (lines / cm). The leading section and the trailing section can be joined together before the subsequent original warp section enters the sizing machine. Furthermore, it is possible to generate a twill present on the surface side on the warp beam after gluing.

In a practical embodiment, the warping drum has a diameter of 2.
It was 25m. This corresponds to a circumference of about 7 m. The warp length was about 140 m, the length of the leading section was about 10 m, and the length of the trailing section was about 8 m.

The partial warping machine shown can be controlled by a different second program as shown in FIGS. In this case, the central dividing rod ST3 shown in FIGS. 4 and 5 has been removed. The remaining dividing rods have also been changed to Leeds rods FK3 to FK6, but this does not require a mechanical design change but only a control program change. In this case, two twill 37, 38 at the beginning of the thread sheet and one at the end.
Two ayas 39 are obtained. This program is suitable for wool that can be woven without gluing. In this case, the second twill 38 at the beginning of the thread sheet is provided as a safety measure in case a defect (flaw) appears in the first twill 37. If such a measure is not necessary, the second hoop 38 can be omitted.

As can be seen in FIG. 8, the cutting rod TT1 functions as a cutting rod, ie the first winding is present and all other windings are below the cutting rod. Cutting rod TT2
Can be considered a fixed rod. This is because, in this case, the first winding thread is located below the cutting rod TT2 and all other winding threads are located above the rod.
Dividing rods (FK5, FK6), (FK3, FK4), (FK1,
By the combination of FK2), a twill is formed in the warp. Before the beam rewinding operation, the dividing rod is pulled out from the warped yarn. Then, a pitch cord (thread passing) is inserted at the time of pulling out.

A beam 37 formed by dividing rods (FK5, FK6) and a dividing rod (FK3, FK3) formed after the beam rewinding operation from the warping drum 2 to the winding beam 16 and from the winding beam 16 to the warp beam 17 are performed. The twill 38 formed by FK4) is on the upper surface side of the warp beam 17 on the upper side. This warp beam 17 is then set on an automatic tie-up machine for "tie-up processing" or directly tied to a loom.
