A modification according to not showing might be similar to the situation shown in Fig. 2, and blowing device 50 is arranged in the below of the fabric 3 that is woven, and as shown in Figure 8 blowing device 50 is arranged in the top of the fabric 3 that is woven simultaneously.A termination of the weft yarn that these two blowing devices 50 allow similarly is blown near the beat-up line 36 the desired position.
To explain operation with reference to figure 9-15 according to device of the present invention.After weft yarn 30 had been inserted into, as shown in Figure 9, the termination 30A of weft yarn 30 was housed inside in the jaw 31 of bearing 32 with known method.Then, as shown in figure 10, this weft yarn 30 is beaten up by loom sley (main shaft of loom) under 0 ° of angle.Indicated as Figure 11, weft yarn 30 is for example cut near 12 somewheres 0 ° of angle of loom by weft yarn and is cut to certain length.After cutting off operation, the termination 30A of weft yarn 30 is blown by the holding nozzle 23 in the retaining hole 24 of bearing 32, and it is held this place, as shown in figure 12.Meanwhile, the fabric 3 that is woven moves forward on the direction that is indicated by arrow P, and the termination 30A that is cut off of weft yarn 30 is blowed element 21 winding-up and enters with in the follow-up shed open, and winding-up element 21 is provided with at least one injection hole 22 and injection hole 25 and 26, as shown in figure 13.This winding-up is for example from approximate 150 °, and ends at approximate 320 ° or a little before or after follow-up shed closed.Meanwhile, foregoing winding-up or slightly after this, blowing device 50 also is activated, and the termination that is directed of winding-up weft yarn, described weft yarn is basically parallel to the weft yarn 30 that before had been directed, as shown in figure 14.According to possible choosing wantonly, blowing device 50 was jetted before next root weft yarn is beaten up from 160 ° to 350 ° or just.Meanwhile, follow-up weft yarn 30B is directed with identical method.Follow-up weft yarn 30B is beaten up with the above-mentioned termination of previous weft yarn 30, causes being in position as shown in figure 15.Because above-mentioned blowing device 50 winding-ups are on the 30A of the termination of weft yarn 30, and weft yarn 30 has inserted in the shed open and just has been imported in the follow-up shed open, this termination 30A is after it has formed great circle 30D, be transferred on the horizontal plane or height that is positioned at beat-up line 36 substantially, and therefore be transferred on the horizontal plane or height of follow-up weft yarn 30B.This has prevented that termination 30A from dropping to the position that is indicated by the dotted line 30C among Figure 13.
According to the character of the termination 30A of the weft yarn 30 that will be inserted into, termination 30A be blowed element 21 and injection hole 25 and 26 be blown into follow-up shed open a little before, a little after or moment, blowing device 50 is jetted.According to a modification that does not show, valve 40,41,42 and 43 can be substituted by single valve, and described single valve is provided with all these injection holes, and these injection holes have the compressed air of connection.Though in fact better be for blowing device 50 provides independent valve 55, according to a modification that does not show, the function of described valve can be by a replacement in valve 40,41,42 and 43.In the case, valve 43 and 55 for example can be replaced by single valve.
Significantly, importing termination 30A in the follow-up shed open is not to implement by jetting, and can use the selvedge producing device of known machinery to finish according to a modification yet, for example as the selvedge folding device of having known from EP-A 332 014.In the context of the present invention, this point is important: the termination 30A that this is directed can be similar to by device according to the present invention 50 winding-ups and be parallel to the weft yarn of insertion subsequently, so as to be disposed in beat-up line 36 and the follow-up weft yarn 30B that is beaten up near.
In the embodiment shown in fig. 3, blowing device 50 can be adjusted in such a way with respect to the angle position of supporting 52: in use, the winding-up in a plane 48 substantially of the injection hole 51 of hollow needle 54, winding-up towards beat-up line 36 or towards the place ahead of beat-up line 36, is perhaps jetted towards the rear of beat-up line fully.The tram of the injection hole winding-up of blowing device 50 can be determined by experiment.Determined: for the weft yarn of most of forms, better be position winding-up to beat-up line 36 the place aheads, and for the weft yarn of some form, to the winding-up of beat-up line 36 back locations better.This will be clearly: in illustrated example, winding-up is to implement towards the rear side of the U type part 9 of the moulding reed wire of reed 7, and so often is to enter shed open towards beat-up line 36 substantially.
Though in fact Fig. 9-15 only relates to and utilizes selvedge producing device 6 that the termination 30A of weft yarn 30 is imported in the follow-up shed open, this will be clearly: selvedge producing device 4 and 5 is similarly method work also.In the case, selvedge producing device 5 is two actions, and each of two termination 30A can be imported into relevant shed open.In the present context, this will be clearly: the blowing device 50 of selvedge producing device 4 is configured near the plane of selvedge 17 of the fabric 2 that is woven.In the case, two of selvedge producing device 5 blowing devices 50 are arranged near the plane of selvedge 17 of the fabric 3 that is woven and respectively near the plane of the selvedge 16 of the fabric 2 that is woven.
This will be clear: all valves 40,41,42,43 and 55 are controlled according to characteristic curve by the control device (not shown) of air-jet loom with known method, described characteristic curve be weave the circulation or weft yarn insert characteristic function.To be clearly equally: selvedge producing device 4,5 and 6 be cut 10,11,12 with weft yarn and can be arranged along the fabric support 8 of loom, makes them can be moved the width of crossing loom. Weft yarn cuts 10,11 and 12 can be fixed in each selvedge producing device 4,5 and 6 with known method, for example as shown among the WO 01/86047.
According to the present invention, do not need to provide maintenance nozzle 23 and retaining hole 24.According to another possible the choosing wantonly that still has, retaining hole 24 also can match with the suction means of weft yarn termination, to replace and to keep cooperating of nozzle 23.Choose wantonly according to another, might be provided for the mechanical weft clamping device of this purpose.If retaining hole 24 or clamping device are not provided, the termination 30A of the weft yarn that has then inserted for example can be maintained in so-called catch threads or the edge yarn (not shown), and described catch threads or edge yarn are put to be made into by the fabric that is woven with along the termination 30A that exceeds bearing 32 scopes.This means that bearing 32 is disposed between the fabric 3 and catch threads that is woven.In the case, termination 30A only is cut off in the moment that this termination 30A is folded into or is imported in the follow-up shed open.If 0 ° is stop position, then this rupturing operation is for example 150 ° of enforcements, and this is similar to this termination 30A and just has been imported into before the follow-up shed open.
Figure 16 figure releases a modification, and wherein the injection hole 51 of hollow needle 54 is not disposed on the line.In the case, each injection hole 51 does not blow to the beat-up line 36 in the same level, but for example, each is individually towards beat-up line 36 winding-ups.In the present context, also might be that for example hollow needle 54 is not positioned to and is parallel to beat-up line fully, constitute the angle that limits but for example be positioned to beat-up line 36.Significantly, injection hole 51 be not must be along warp direction towards beat-up line 36 winding-ups, but also may jet, and for example be directed a little center towards the fabric that is woven along constituting low-angle blowing direction with warp direction.
In the embodiment shown in Figure 17-19, it is movably that the hollow needle 54 of blowing device 50 is arranged to.Blowing device 50 comprises and is used for substantially moving along weft direction the drive unit 28 of hollow needle.For the termination 30A of weft yarn is imported in the follow-up shed open, as shown in figure 17, hollow needle 54 is positioned to by the fabric 3 that is woven.When the termination of weft yarn 30 30A was imported in the follow-up shed open, hollow needle 54 was moved along weft direction substantially, so that obtain the horizontal plane position on every side of the selvedge 16 of the fabric that is woven 3 below the fabric 3 that is woven.In the case, injection hole 51 winding-ups of hollow needle 54 cause position as shown in figure 18 on the 30A of the termination of weft yarn.Then, hollow needle 54 moves, and for example until reaching position shown in Figure 19, and injection hole 51 continues winding-up.This makes the termination 30A of weft yarn 30 be placed in to be parallel to follow-up weft yarn 30B substantially fully, and formerly obtains great circle 30D between the termination 30A of the part of the weft yarn 30 in the shed open and the weft yarn 30 in the follow-up shed open.This will be clearly: the blowing device 50 shown in Figure 17-19 only some the time be disposed in around the horizontal plane of selvedge 16 of the fabric 3 that is woven, and only some the time be substantially towards beat-up line 36 winding-ups.
According to embodiment shown in Figure 20, blowing device 50 keeps rotatable, and drives rotation by drive unit 28.This for example can be regarded as: make the hollow needle 54 of blowing device 50 rotate around it the axis rotation.For example, this soon, allowed blowing device 50 towards beat-up line 36 winding-ups before follow-up weft yarn 30B is beaten up.The rotation of blowing device 50 made before follow-up weft yarn 30B is beaten up, and described blowing device especially can make the termination 30A of weft yarn 30 form great circle 30D, and termination 30A is woven into follow-up shed open substantially towards beat-up line 36 winding-ups.If blowing device 50 shown in Figure 20 also can move with identical method as the blowing device 50 shown in Figure 17-19, this just rotates and can take place, and for example, it shifts to position shown in Figure 19 from position shown in Figure 180.It may retract position shown in Figure 17 from position shown in Figure 19 then.
Figure 21 and 22 figure release another modification that still has, and wherein blowing device 50 comprises the hollow needle 54 that is fixed in fabric support 8.
