In a process to weave a high quality ribbon for use in florists' product presentation, an existing ribbon is decorated by the introduction of one or more figuring shoots following an oscillating track. The figuring shoot is introduced by a separate assembly from that used to weave the parallel ribbon. Also claimed is a commensurate figuring shoot assembly.

Description

The The present invention relates to a process for producing a woven tape according to the preamble of the main claim and a ribbon loom to carry out of the procedure.

such a Methods and such tape looms are known. See, for example, B. KIPP Hans Walter, Bandwebtechnik, Verlag Sauerländer 1988.

such bands There are endless forms, widths, variations and colors.

to Manufacture serve tape looms, of which those with weft insertion devices in the form of shooters or weft insertion needles must also be attributed to the known state of the art.

at the shuttle looms it is known that a Figure thread, which is also referred to as Einzugsfaden, from the Kettrichtung coming from the thread in the wiper transversely to the warp direction predetermined piece is taken to bind him at a predetermined location to be able to.

This So far, however, the method is only available on tape looms in contactor technology possible.

Out DE-PS 26 83 it is known, in each case a plurality of warp threads in parallel to move each other curvilinearly. The curvilinear laid warp threads leave within their laying width no further warp thread too.

It It is therefore an object of the invention to propose a method with which the collection of figure threads both in shuttles as well as at shooter tape looms possible is.

These Task solves the invention with the features of the main claim.

Further The object of the invention is to be suitable for carrying out the method To create device.

These Task solves the invention with the features of claim 15.

Out The invention results first once the advantage that regardless of the particular construction of the ribbon loom, i. independent of the weft insertion device, a figure thread can be fed with.

This Advantage is achieved in that the figure thread by a separate and vertical to the shed movable thread guide member to be led, which is controlled according to a predetermined law, that the Figure thread after every predetermined number of wefts on the respectively current place of setting and only immediately before the next Abbindevorgang down to the level of the lower shed and lowered in the next Operation tied off with the weft can be. Then the compartment can recede and the process according to the invention repeated later become. Preferably, the lowering takes place simultaneously with the lowering other warp threads.

By then Lifting the relevant thread guide member, which is provided after one, two or more wefts, is the Figure thread then held above the upper tray again so long until the next lowering process and the setting process is repeated.

there The figure thread can also from Abbindestelle to Abbindestelle right and left over the bandwidth between the outermost ones warp be relocated.

Essential In any case, the lowering of the thread guide member so far that the figure thread from the thread guide starting from the thread guide organ reached to the level of the lower compartment to be involved there to become.

in principle let yourself but also a ligation with the warp threads of the upper tray, if the separate thread guide member the compartment fed from below can be.

there can the figure thread both in the longitudinal area of the warp threads between the end of the compartment opening and the reed as well - in Running direction of the warp threads seen - before the passage of the warp threads fed by the reed become. The feeder is possible at each point between the strands and the end of the compartment opening. If the delivery occurs at one point before the warp threads through the reed, but must the reed, which is usually above and below by a yoke, also referred to as collar and spring, is closed, at the point where the figure thread in the Web structure of the tape to be integrated, on the feed side be open. So if the figure thread is supplied from above, is this was advised above.

Of the Figure thread is running then, if necessary, one more additional Thread guides, behind the reed in a straight line towards its point of demarcation.

This development has the advantage that the predominantly movable in the vertical direction additional thread guide member for the figure thread can be connected via a suitable support construction with a shaft of the ribbon loom. Since such a tape loom always have multiple shafts, it requires no complex conversion measures on the ribbon loom to realize the invention.

One Another advantage of this development is that in this longitudinal section the warp threads clearly more space for the vertically moving thread guide member to disposal stands, as in the relatively narrow area between the end of the compartment opening and the reed and - corresponding Construction of the ribbon loom with weft insertion needle provided - the weft insertion needle, so that too the sometimes very closely running warp threads through the immersion movement of the additional thread guide member not disturbed can be.

This is particularly in view of a uniform possible warp tension advantageous since the warp threads naturally further spaced from each other before entering the reed could be as between the reed and the end of the shed opening.

there can the figure thread practically over the entire width of the band to be woven with.

From However, the advantage for optical reasons is a further development which the figure thread within the edge regions of the tape in whose middle area is woven.

In addition, can about that In addition, the figure thread from Abbindestelle to Abbindestelle also be moved back and forth.

This is achieved by the separate thread guide member from one dip to the next Submerged motion or one of the next submerged movements additionally in adjusted in horizontal direction.

there corresponds to the adjustment of the additional thread guide member essentially the distance, the two provided and similar decorated Rietlücken in the Riet, so that the Figure thread from one point of attachment to the next point of attachment in addition to Lowering and subsequent Lifting also from one Rietlücke to the other Rietlücke and back can be moved.

Without restriction This is in principle also possible for the case in which the additional Thread guiding member in the longitudinal area the warp threads dips between the reed and the end of the compartment opening.

considered you about it addition, such Ribbon weaving machines usually several shafts have, so can quite a few different figurative threads can be confiscated at least one shaft per shaft. But not more than 2 shafts activated. Also, a shaft can move several figure threads.

in the Trap of several figure threads can also realized different zig-zag contours for the individual figure threads become. For creating zig-zag contours it is suggested that the separate Thread guiding member sitting on a rotating carrier.

there come in particular different figure threads into consideration, with the same wavelength but different amplitudes both in-phase and offset-phase to be woven.

customarily are such bands intended for decoration purposes.

The Therefore, relatively loose mesh binding may be after a relatively firm Demand ligation of the figure thread in the tissue.

To For this purpose, it is proposed that the setting of the figure thread takes place at each Abbindestelle with a double shot.

Should this is not sufficient, it is proposed in addition to perform the setting by means of an even number of multiple weft threads, in particular each with 1, 2 ... double shots, so 2, 4, 6 ... etc. wefts.

These Training can be therefore without further construction measures especially easy to realize on a ribbon loom, the one pick needle as a weft insertion device having.

There in such a tape loom, the weft always from one side coming as a loop must be laid on the opposite Page e.g. crocheted is, automatically results in the integration of the figure thread each tapping point with a double shot.

If about that In addition, the figure thread each on a warp thread of the lower Fachs is hung up before it is tied, can be the invention is simple to conventional Realize ribbon looms, because then the supply of the withdrawal thread of can be done above.

in the Following, the invention will be explained in more detail with reference to embodiments.

4 Control of the thread guiding organs according to the invention by heald frames

Provided not otherwise stated below, the following description applies always for all figures.

The figures show the inventive method for producing a woven tape 1 on a ribbon loom, which is shown in the details of interest here.

The band consists of mutually parallel warp threads 2 and transverse thereto weft threads 3 ,

The Wefts are in a conventional manner by a weft insertion device in the shed entered, then enters the subject and there is a new weft entry etc.

Depending on the design of the machine, the weft will pass over a shooter or a picking needle 18 entered.

Provided in the following is not separately indicated, are always covers all types of such tape looms, especially those with heald work.

In addition to the warp threads in the present case a figure thread, also called thread, woven into the band. It is essential to the extent that at least a single figure thread pulled and woven into the band becomes.

To show the 1a . 1b and 3 Exemplary embodiments with several figure threads 4a . 4b ,

To these figure threads 4a . 4b weave in, every single figure thread 4a . 4b in the direction of the warp threads 2 before the end 8th the compartment opening above the level 9 the upper compartment of a separate thread guide member 6a . 6b guided, while the respective thread guide member remains 6a . 6b in the above the level 9 the upper tray position and the normal weaving operation with tray passing after each picking, etc., are performed.

After each predetermined number of weft threads then the figure thread in question by means of the thread guide member 6a . 6b so far lowered that he is at a position immediately before the end 8th the compartment opening practically at the level 10 the threads of the lower compartment runs, so that it can then be tied off with the next shot entry.

Of the retracted figure thread is then in a conventional manner with the then registered weft tied.

After the complete setting of the drawn figure thread is next the separate thread guide member 6a . 6b until the next binding process again led above the upper tray until a re-tuned number of weft threads during normal weaving has been entered with respective passage of the tray.

Only then is the separate thread guide member 6a . 6b with the respective retracted figure thread lowered again until the figure thread at a point immediately before the end 8th the compartment opening is at the level of the threads of the lower compartment runs so that it can be re-involved with etc.

In this case, the figure thread 4a . 4b in the longitudinal area of the compartment between the reed 7 and the end of the compartment opening, so where the Abbindestellen 5 lie, are fed between the running there warp threads of the upper compartment from above.

The 2a . 2 B and 4 However, show a development in which the figure thread 4a . 4b in the direction of the warp threads 2 seen before the reed 7 is supplied at a location at which the reed 7 a top open riet gap 11a . 11b having. The position information "before" or "behind" the Riet refers in the present application from the point of view of the direction of the warp threads and not as usual from the perspective of standing in front of the machine operator.

The open top riet gap 11a . 11b is doing through a gap in the upper yoke 12 of the reed 7 determines from where the retracted figure thread then seen in the direction of the compartment of his Abbin least elle 5 tapers.

For this purpose, the figure thread 4a . 4b - Seen in the running direction - behind the respective separate thread guide member 6a . 6b the Rietlücke and from there the Abbindestelle 5 fed.

To insert the figure thread 4a . 4b in the respectively assigned above open Rietlücke 11a . 11b to allow, are appropriately executed Fadenleitkanten 13a . 13b provided, over which the figure thread 4a . 4b with the lowering movement of the respective separate thread guide member 6a . 6b guided and with further lowering movement in the Rietlücken 11a . 11b is introduced.

It is therefore in this embodiment of the invention, in which the separate thread guide member 6a . 6b in the direction of the warp threads 2 seen sitting in front of the reed, only on the fact that the respective thread leading edge 13a . 13b a Eintau chen of the current figure thread 4a . 4b in the open space above 11a . 11b allows.

As well as the 1 and 3 show, the at least one figure thread 4a respectively. 4b within the width range of the band 1 woven in, between the outermost warp threads 14a . 14b lies.

The integration of the figure threads 4a . 4b takes place here in the middle band area, so that the decorative effect of such a band, for example by an edge region with very small Kettfadenabständen and a central region with larger Kettfadenabständen and with one or more alternately threaded figure threads in the central region is considerable.

The individual figure threads can 4a . 4b with the same wavelength 15 but different amplitude 16 be laid and there may be single or multiple figure threads 4a . 4b be moved. The figure threads can run in phase or out of phase. Thanks to the invention, the creative possibilities are limited.

The Laying preferably takes place with a rotating thread guide element, so that gives the zig-zag line from the rotating motion.

In addition, the detailed representations show in particular the 1a and 1b such as 3 in that the tying of the figure thread at the respective tying point 5 with a so-called double shot 17 he follows.

this includes is to be understood that the registered weft practically inserted as a loop, which is between the previous coming from the entry side but already tied off weft and the weft insertion device forms, the latter at its leading point in the registration direction an eyelet for the supplied weft having.

This is in the practical case by a weft insertion needle 18 realized.

Here in is a special feature of the invention, because with such tape looms the weaving of a drawn-in figure thread was previously not possible and the catchment effect at most about an additional piercers let imiitieren approximately.

Nevertheless, the invention also claimed for the possibility to be applicable to a ribbon loom with shooter entry, namely because the drawn-in figure thread on a separate thread guide member 6a . 6b and no longer - as previously known - on the weaver of Abbindestelle 5 to tie point 5 is relocated.

If one forms such a band in the middle area with a relatively large mesh width, the warp threads are also formed 2 spaced correspondingly far apart.

Around the drawn-in figure thread 4a . 4b nevertheless be able to bind firmly, it is additionally proposed that the setting takes place in each case with an even number of multiple weft threads.

In particular, then the invention can also run on a ribbon loom, in which the weft insertion device as a weft insertion needle 18 is formed, which dips from only one side into the compartment. For the sake of completeness, it should be noted that such a weft yarn is crocheted on that of the tape edges, which is opposite to the Nadeleintragsseite.

In addition to this show the 2a and 2 B multi-dimensional views for laying the figure threads.

Appropriately, the figure thread 4a . 4b on a warp thread 2 placed on the lower shelf and then tied with.

kick namely then before the next weft insertion the tray to, the retracted figure thread is still on the previously lower bottom warp and is the next weft entry fixed again.

The setting takes place until the se parate thread guide organ 6a . 6b again over the plane 9 of the upper compartment is raised.

In addition to this show the 2a . 2 B and 4 the devices suitable for carrying out the invention on a ribbon loom.

The separate thread guide member 6a . 6b sits at rest before the end of the compartment opening, here exactly between the strand and Vorderriet, and above the upper compartment.

It is on a vertical guide 20 towards the plane 10 the threads of the lower compartment lowered and after a predetermined number of wefts 3 moved back to the original position.

How complementary 4 shows, is the thread guide member 6a . 6b in addition to the vertical mobility in the transverse direction by a corresponding transverse drive 21 movably driven.

In the embodiment gem. 4 is the separate thread guide member 6a . 6b in the vertical direction by a shaft 19 the ribbon loom driven.

It sits, as it were, rigidly with the shaft 19 connected to this.

In addition, there is between the holder of the thread guide member 6a . 6b on the shaft 19 and the shaft 19 even a horizontal guide, with which the holder on the shaft 19 in the horizontal direction is movable.

For adjustment of the holder 30 serves a gear coupling device between the holder 30 and another shaft 22 , Known, the other shaft 22 also make an up and down movement.

With the other shaft 22 is a slanted guide 23 connected, in which one with the holder 30 connected rolling bearing 31 intervenes.

Will now the other shaft 22 moved up or down, the rolling bearing 31 shifted to the right or left so that the holder 30 then also correspondingly also shifted to the right or left and the associated thread guide organs 6a . 6b takes along accordingly.

Here, the inclined guide 23 an upper end position 24 and a lower end position 25 taking.

The displacement path between upper end position and lower end position corresponds to the distance 26 which is as big as the distance 27 that is between two assigned Rietlücken 11a . 11b certainly. In any case, the geometry of the inclined guide 23 variable adaptable to the required displacement path.

It can therefore by an upward and downward movement of the second shaft 22 a reciprocating motion of the separate thread guide members 6a . 6b take place, as well as it the laying scheme of the retracted figure thread 4a . 4b required.

Depending on The respective desired laying pattern can also be several shafts with such be equipped geared couplings.

Furthermore, in particular show the 2a . 3 and 4 a special education of the reed 7 ,

This is open at predetermined locations, ie the usually existing upper yoke of Rietes is interrupted, so that there is an open-top Rietlücke 11a . 11b etc. trains.

In addition, there are preferably thread-like rounded thread guide edges 13a , b, etc. provided so that the on the respective separate thread guide member 6a . 6b etc. figure thread supplied 4a . 4b etc. straight from the separten thread guide member 6a . 6b to the Rietlücke 11a . 11b and from there runs in a straight line or slightly curved depending on the respective thread tension.

It can therefore with the invention, a wave-shaped figure thread 4a . 4b to be confiscated.

The figures also show a reed 7 which is open at several places at the top.

Each reiet therefore has several thread guide edges 13a , b etc. on.

Each thread guide edge 13a , b, etc., each in a Rietlücke 11a . 11b etc.

The broken in this way upper yoke is designed triangular and extends from the top open Rietlücke to above open Rietlücke with the triangle tip up so that each triangle leg as Fadenleiteinrichtung in each case a neighboring Rietlücke points.

When descending the respective separate thread guide organs 6a . 6b Therefore, the thus supplied figure thread is introduced over the respective thread leading edge clearly in each case a single Rietlücke, regardless of where exactly the separate thread guide organ 6a . 6b stands.

The separate thread guide member 6a . 6b Therefore, it must only be clearly on one of the two sides of the triangle tip before it is lowered.

In addition, the figures show an embodiment where the separate thread guide member 6a . 6b in the direction of the warp threads 2 seen before the reed 7 sits, ie from the point of view of the machine operator "behind" the reed.

For this case results with the help of separate Fadenumlenkorgane 29 a simplified guide.

For this purpose, a thread deflecting member is in each case 29 provided, which between the separate thread guide member 6a . 6b and the reed 7 sitting.

The Fadenumlenkorgan is sized in height and height position so that the retracted figure thread 4a . 4b in all height positions of the separate thread guide member 6a . 6b at the respective Fadenumlenkorgan 29 is applied.

The figure thread 4a . 4b therefore changes its overflow point on Fadenumlenkorgan 29 depending on the obliqueness to the last setting point.

In addition to this offers the separate Fadenumlenkorgan 29 also the possibility of the reed 7 tapered warp threads aufzusachen so that for the reciprocation of the separate thread guide member 6a . 6b enough space remains, without interfering with the respective dipping movement in the direction of the warp threads of the level of the lower compartment, the course of the incoming warp threads.

This situation is in 2 B shown.

The respective Fadenumlenkorgan 29 therefore serves the purpose of the reed 7 tapered warp threads to lead so that between two adjacent sets of warp threads sufficient lateral space for the plunge movement of the separate thread guide member 6a . 6b is available.

The thread deflecting organs 29 can therefore also be referred to as spacers.
