Abstract

Two rotational selvedge leno devices with their stators (15, 17), rotors (16, 18) and rotational axles (33, 34) are arranged one after the other opposite the direction of drawing (4) of the woven cloth and with an increasing diameter. The leno threads (23, 24 and 27, 28) form full leno selvedges by traversing the thread guide eyelets (25, 26 and 29, 30) in the rotors (16, 18). Two holding cheeks (12, 13) bear the rotational selvedge leno devices. The two holding cheeks are connected by means of a lockable sliding seat (14). The holding cheeks are displaceably fixed to a stationary transversal axle (9) by means of a clamping bushing (11). The device is characterized by its narrow construction, which makes it particularly advantageous for forming fabric edges in multiwidth fabrics.

Description

On loom, be used to form the device of leno edges and have the loom of this device
The present invention relates to a kind of device that is used to form leno edges on loom, leno edges is parallel to the warp thread of several fabric to be made, and its doup end yarn makes the weft yarn of introducing interweave as warp thread equally.
The present invention also relates to a kind of loom that a kind of such device is housed.
DE 19720634 C1 disclose a kind of device that starts described pattern.Also visible DE 4405776 C1 of the details situation of this known devices and DE 4405777 C1.
The notion of " leno edges " has comprised the selvedge that passes through the twisted various types that forms of doup end yarn on a kind of fabric in this application.For example can refer to a kind of fabric limit herein, it is stayed on the fabric enduringly and in use plays the terminal of this fabric and the effect of protection.But equally also can refer to a kind of ruffle, the weft yarn that its prevention is introduced retracts from the warp thread of edge side.A kind of such leno edges is made of the doup end yarn of leaving behind from certain leno bobbin.
In according to the described known devices of DE 19720634 C1, be provided with at least two rotary selvedges side by side and play the strand device with common rotation axis.Each rotary selvedge plays the strand device and becomes rotary body with a kind of shaped design of flat, annular dish, and it drives and its inside member of not packing into from the outside.The rotation of rotor thereby be not structural member, but a kind of imaginary geometrical axis.This structure that known rotation strand is changeed device can realize that twisting the parallel that changes and in the end introduce mutually by the feasible doup end yarn that goes out from each bobbin lira of the half way around of stator produces a kind of full strand tissue.Just can in real weaving process, side by side on the fabric that produces, form two kinds of different leno edges with these known devices.For example can be meant a kind of fabric limit and a kind of ruffle herein, they are positioned at the edge of fabric, and mutual spacing is opened.From the fabric of making, will have the ruffle on limit to downcut with a kind of separator, and the fabric limit is still stayed on the fabric of making.
People just expect at first, and design has this leno edges on the edge of generation fabric in weaving process, and under the pressure of process economically former thereby require more and more: the fabric of making double width also separates weaving process after.Therefore can realize higher wefting insertion efficient and reduce the weft yarn waste material.Even therefore require the fabric limit in the centre, the edge in adjacent webs disposes full strand tissue when implementing in other words.If warp thread is pulled out by the lease making axle, thereby for two rotary selvedges of layout play the strand device, there is necessary centre-to-centre spacing, adopts and to implement a kind of such mode of production at an easy rate at least according to the described device of DE 19720634 C1.But more and more wish two or more webs are pulled out and still produced to warp thread coherent through axle (single-yarn textile) from one.Therefore no longer warp thread piece is being separated in the shed open of back under this operation principle, it is just very little to be used for therefore arranging between the edge of each webs warp thread that rotary selvedge plays the position of strand device.Warp thread and doup end yarn can be in contact with one another, because warp thread dabs and skims over rotary selvedge and play the strand device.Therefore will cause clamping for fine yarn, perhaps in the long filament position, if warp thread does not have twisted or has only producer twist, that will cause monofilament to damage.Therefore may strengthen warp thread broken yarn number causes shutdown, therefore strengthens production loss.
Thereby task of the present invention is to propose a kind of device that starts described pattern, even just can have leno edges several fabrics as full strand tissue having to link up to make on the loom of axle with this device, and needn't fear to disturb the process of weaving cotton cloth or reduction quality.
This task solves by all features of claim 1.
Therefore propose a kind of device, wherein have two rotary selvedges to play the strand device and be assembled into a structure member in tandem and be following feature:
A) each rotary selvedge plays the strand utensil a stator and a passive rotor;
B) rotation of rotor is parallel to each other substantially;
C) each rotor has at least two mechanisms that are used for guide, passes these mechanisms and makes at least two doup end yarn guiding be used to form one strand shed open;
D) rotation of the rotation axially parallel ground of at least one in the rotor and rotor or other rotor is arranged at interval.
Therefore kept the advantage that plays the strand device according to the described known rotary selvedge of DE 19720634 C1 according to device of the present invention, this just can make leno edges form full strand tissue by favourable mode and rise in the independently control device that twists device at least two rotary selvedges has special advantage.Yet revise known devices in the following manner: the rotation of at least one in the rotor is positioned on the direction of warp thread, with the rotation of rotor or other rotor spacing is arranged.Make the rotation selvedge play the hinge device according to this and arrange abreast no longer mutually, but polyphone ground one in front and one in back is arranged on the warp thread direction.Therefore stator and subsidiary bracket are packed on the traffic direction of warp thread in tandem.Whole device is therefore narrow; It is built on the length and no longer on width.If with warp thread is not from the lease making axle, but from coherent leaving behind through axle, this also just can realize by being arranged in the warp thread piece so.
Favourable improvement design according to a kind of device of the present invention is: the rotor that the space is arranged is disposed aligned mutually on the direction of warp thread.This self-evident layout that also has influence on attached stator and carriage thereof.The device strictness is one in front and one in back arranged alignedly if rotary selvedge plays strand, so can be on width of fabric the saving locus of maximum possible.
In addition, importantly according to a kind of favourable design: rotor be flat annular disk and also for example each annular disk all be the rotor of a motor.Therefore in the length of having saved the position on the width and having made device a plane perpendicular to fabric web.
In addition,, make one in front and one in back the diameter of the rotor of arranging be designed to stairstepping, so its diameter increase in contrast to the transport direction of fabric according to a kind of favourable technical scheme.Rotor and whole rotary selvedge play the strand device and are matched with preceding shed open by this way, and its method is: its diameter increases until the maximum height of shed open gradually from the lugs of fabric.Therefore under the simplest situation, be exactly that second bigger rotary selvedge of appearance and size plays the strand device after an appearance and size small rotation formula selvedge plays the strand device, wherein appearance and size is mainly determined by the diameter of rotor.But also can be at an easy rate have rotary selvedge more than two and play that design has corresponding structure in the device of strand device a kind of, these play the strand device and arrange in tandem.Device adapts to the size of opening shed open best in this mode, and this is opened the shed open size and is made of warp thread and therebetween doup end yarn.Therefore also guaranteed to make the weft yarn interference-free to introduce.
According to another kind of design, preferably play the strand device by device of the present invention and be fixed on the common carriage with its all rotary selvedge, this carriage can be swung and move on this axis around an axis that is parallel to the wefting insertion direction layout of weft yarn.Can carry out fine tuning to device by swing in this way.But at first can move generating on the width of fabric, therefore can when double width or several are weaved, on each fabric web, realize an a kind of left side and the leno edges right side.Device is fixed on the frame from top, can upwards swinging in the warp thread piece and when not using thereby device is slipped into from above to a certain extent.Equally also can consider with following arrangement: device under slip in warp thread piece, in that the time spent then can be to lower swing.
The another kind of scheme of this carriage is: each rotary selvedge plays the strand device, and this can exchange and laterally fix movably on carriage.Also have other advantage except the advantage of interchangeability: one in front and one in back the strictness of each rotor of Bu Zhiing alignment can be cancelled in certain scope, thereby the leno edges that is generated from the beginning just has certain spacing.Certain this scheme just can be used in more among a small circle, has lost again because otherwise save the advantage of locus.
In addition advantageously: all rotors are provided with single drive division and a control device are arranged in according to device of the present invention, by this control device all rotors are driven independently of each other.In a kind of such design, for each leno edges, can independently irrespectively select the starting moment of rotor, and can for each leno edges, after one or more weft yarns are introduced, differently interweave with another.
According to this details of another design, knit reed or a kind of subsidiary reed shape device of knitting, for example a kind of auxiliary knitting in the guider that reed all is included in the doup end line.
According to claim 9, the present invention also relates to a kind of loom with at least one by described device one of in the claim 1 to 8; A kind of fabric of forming by at least two fabric webs of this loom processing.Between the warp thread piece of two fabric webs, arranged according to device of the present invention.The simplest situation is: have only one to be arranged in according to the described device of claim 1 to 8 and to be used to generate leno edges between the warp thread piece.
But also warp thread piece repeatedly can be segmented and is laid on the width of warp thread piece according to assembly apparatus branch of the present invention at an easy rate a plurality of.
If when mainly generating on width fabric or warp thread piece according to device of the present invention being arranged at owing to its narrow structural shape also is favourable, the another kind of favourable design of loom also just is so: be located on the edge wefting insertion side or that go out the latitude side that generates fabric according to device of the present invention, and form a kind of leno edges on next door, fabric limit in ruffle.In addition, loom can be provided with the device that generates the leno edges that is a kind of pattern.Therefore purchasing and cost can be saved in aspect such as spare part.
Then the present invention is described in detail with an embodiment.As follows shown in the accompanying drawing:
Fig. 1 is a diagrammatic top view of seeing a loom from above, and this loom is equipped with according to device of the present invention,
Fig. 2 has represented the partial view corresponding to A-B line among Fig. 1.
1 is warp thread in Fig. 1, and the pull-out direction of their fabrics in Fig. 14 transfers to the left side from the right side.Represent weft yarn with 2, it is introduced in the shed open of opening usually on the incoming direction 5 that is transverse to warp thread.Warp thread 1 and weft yarn 2 have constituted the fabric or the fabric web 3 that generate jointly, and it is being drawn out in loom on the pull-out direction 4.Represent a separator with 6.
As start described, some fabric all is made into many times of width at present and then separates.Be made into double fabric width in the embodiment shown, and then these two halves separated and proceeded separately processed with separator 6.Represent that with 7 is knitted a reed, knit the weft yarn that reed makes last introducing with this and block on the backstop limit of fabric or ruffle.The structure of loom belongs to prior art, does not need to explain detailedly.
Be fixed on a transverse axis 9 according to the device that is used to generate leno edges of the present invention, this transverse axis is connected with frame by means of a carriage 10.Slide on transverse axis 9 closing sleeve 11 is housed, this sleeve can rotate also and can vertically move on axle around transverse axis 9, visible for this reason direction arrow 31.Hang first stop yoke 12 on closing sleeve 9, this stop yoke is connected with second stopping wheel 13 by the sliding seat that can fix 14.Can make second stop yoke 13 be transverse to warp thread direction by means of sliding seat 14 and move and also can retighten, visible direction arrow 32 with respect to first stop yoke 12.But sliding seat also can be separated and allow to replace this second stop yoke with position mechanism thereon.Closing sleeve 11, first stop yoke 12, second stop yoke 13 and fixable sliding seat 14 have constituted the carriage that two rotary selvedges that are used for then will being illustrated play the strand device together.
First selvedge plays the strand device according to first stator 15 that includes shown in Figure 2, and it is fixed on second stop yoke 13, also has first rotor 16.Second rotary selvedge plays the strand device and is made of second stator 17 and second rotor 18.Second stator 17 is fixed on the some 12a on first stop yoke 12,12b place herein.Fig. 2 can know and sees: stator is fixed on the stop yoke with fastening projection provided thereon and attached hole.
The diameter of first rotor 16 is less than the diameter of second rotor 18.The stator 15,17 that surrounds rotor 16,18 also is like this.Rotary selvedge plays the maximum open that therefore the strand device is matched with the shed open that is constituted by heald frame 8 basically, and shed open trend by doup end yarn 27 and 28 in Fig. 2 can be seen.This structural design makes that the device be used to generate leno edges is easier and adapts to the trend of shed open and also make its easier being arranged at afterwards in shed open 35 positions heald frame 8 after.
Represent four bobbins with 19 to 22, four doup end yarns 23,24 and 27 and 28 are arranged above them.With 25,26 and 29,30 expression guide eyelets, they have constituted the mechanism of the yarn that is used to lead in this embodiment.First doup end yarn 23 fallen by first bobbin 19 strands and flows to first rotor 16 by guide eyelet 25.Second doup end yarn 24 fallen by second bobbin, 20 strands and flows to first rotor 16 by guide eyelet 26.When 16 rotations of first rotor, make on the weft yarn that first doup end yarn 23 and second doup end yarn 24 introducing twisted and therefore interweave with it.This is possible, because first rotor design becomes a kind of form of flat annular disk and risen by its circumference and to be driven.Therefore the inner chamber of first rotor 16 member of not packing into just can make first doup end yarn 23 and second doup end yarn 24 intersect uninterruptedly.
Correspondingly be provided with and have larger-diameter second kind of doup end yarn.Here the 3rd doup end yarn 27 fallen by the 3rd bobbin 21 strands, and the 4th doup end yarn 28 fallen by the 4th bobbin 22 strands, and is defeated by second rotor 18 by means of guide eyelet 29 and 30.Therefore the 3rd doup end yarn 27 also can frame up the limit with the 4th full reeled yarn of doup end yarn 28 twisted generations, thus the weft yarn 2 that makes last introducing reliably stop live.
For fear of at doup end yarn 23,24; 27,28 and rise adjacent to rotary selvedge and produce to clamp in place the upper edge between the edge warp thread of weaving warp thread of strand device and release direction 4 and play strand device front at rotary selvedge and be provided with so-called sept 37,38.
Two rotor drivings from the outside for example can be undertaken by belt, and these belts are by a common motor or also can be driven by each motor.But rotor also can be the rotor of motor, and its stator is selvedge strand rotation mechanism simultaneously.These details are open in described DE 19720634 C1, so this respect can be referring to the document.
Two rotary selvedges play the rotor of strand device around imaginary how much rotations 33 and 34 rotations, and these axis are transverse to warp thread direction, just are parallel to the incoming direction 5 of weft yarn 2.These two imaginary rotations 33 and 34 one in front and one in back have at interval and are arranged on the direction of motion of warp thread.Two rotary selvedges play the strand device at warp thread 1 with generate on the pull-out direction of fabric 3 and align as seen from Figure 1.Therefore they have width smaller, and as playing the strand device by many times of known selvedges of prior art, they are arranged mutually abreast with common axle.As Fig. 1 particularly is clearly visible, can be used in the middle of the warp thread piece of fabric to be made, generating leno edges by charging apparatus fully.
By shown in Figure 1, with all doup end yarns left side on the direction of motion of warp thread, flow to rotor 16 and 18 below just being in the drawings, and on direction of motion the right, leave rotor above just illustrated.Therefore they nestle up when going out in rotary selvedge strand device from first mutually side by side.
Readily understand the function that is used to generate leno edges according to device of the present invention by above explanation. Doup end yarn 23,34 and 27 and 28 is fallen by bobbin 19 to 22 strand, through rotor 16 and 18 guiding, and just twisted mutually in couples after introducing at least one weft yarn 2, thereby the weft yarn of introducing is interweaved and fixes.Because the doup end yarn also at the input side of rotor by twisted, therefore must after certain number of turn-taking, make direction of rotation conversely.When two single drivings of rotor and when a kind of corresponding independent control device, just can freely programme: each that rises in the strand device for two rotary selvedges should make direction of rotation reverse after changeing how many circles.In other words can be when first kind of leno edges, for example after each wefting insertion, carry out twisted and interweave, but then be when second kind of leno edges whenever for the third time or after the 5th wefting insertion.Equally also can be independent constantly and stop constantly to programme irrespectively to the speed of each rotor and starting with other rotor.Just determine the limit by the operation of weaving process herein, it requires to make when forming shed open rotary selvedge to play strand device and loom synchronous operation to a certain extent at least.
By just can on width of fabric to be made, change the position of the device that is used to generate leno edges at mobile closing sleeve 11 on the transverse axis 9.That is to say and on different width, to distribute warp thread along the longitudinal direction.Can also make first rotary selvedge play strand device 16,17 by this sliding seat that can fix 14 adjusts with respect to second rotation selvedge strand device 17,18 by way of parenthesis.If align mutually but two rotary selvedges play the strand device, as shown in Figure 1, that maximum that has just realized the locus is saved.First rotary selvedge plays the strand device also can easily change another seat by means of fixable sliding seat 14.
Arranged in tandem that in an illustrated embodiment two rotary selvedges play the strand device.But can arrange at an easy rate that also plural rotary selvedge plays the strand device.
At last, device described here has one in front and one in back and the rotary selvedge of alignment plays the strand device, it also can be arranged on fabric to be made the wefting insertion side and go out on the outward flange of latitude side.
