WO2011154449A1 - Loom for producing woven goods or material with an incorporated cover thread - Google Patents

Abstract

In order to improve a loom for producing woven goods or material (10) with an incorporated cover thread (12), it is proposed to provide a laying device at least one cover thread (12) and also a warp-laying device (9) with warp-laying elements (14) for laying further warp threads (8). The warp- laying device (9) is designed such that it can make the further warp threads (8) penetrate from a starting position through the upper shed (5) to the lower shed (4), or through the lower shed to the upper shed, and therefore the weft-insertion device (7) crosses the further warp threads (8). The laying device has at least one cover-thread guide (13) which, in the starting position of the warp-laying device (9), can be displaced transversely to the warp threads (2) by way of a transverse-movement means.

Description

 Weaving machine for the production of woven goods with a built-in laying thread Technical field

 The invention relates to a loom for the production of woven fabric with an incorporated laying thread.

State of the art

 A loom of the type mentioned is known from CH 490 541. There fastening threads are arranged by means of feeding needles during the weaving of a band. There are no indications as to how the needle loom could advantageously perform the weaving in of a conductor thread, in particular of an antenna thread. Similar technology has been independently disclosed in US 3,796,234. From WO 2007/071077 AI is known to incorporate a conductor thread in various ways by the feed needle is arranged on a transverse to the warp direction shaft provided with a first drive device for performing a pivotal movement of the shaft and further with a second drive device for method in Axial direction is connected. The engraver dives by pivoting in the shed on and off. This allows the engraver to be moved across the width of the tape.

From JP 2005/015954 A, a loom for weaving an effect thread is known, which can be incorporated into the base fabric or rests on the base fabric. The loom of JP 2005/015954 A is with a

Shed forming device equipped for the warp threads, which makes it possible to select individual warp threads. The effect thread is a selected, additional warp thread. Both the effect thread and additional warp threads are guided within the shed. This has the consequence that the effect threads of the warp, which is supplied from above the additional warp threads and the selected effect thread, are tied off from these warp threads during a transverse movement of the effect threads. This means that the effect threads are not above the Basic tissues are attached, but become part of the basic tissue and thus change the structure.

Presentation of the invention

The object of the invention is to provide a loom which is suitable for the production of woven fabric with a trained-in laying thread. The machine should be suitable for applying a load on a Webgut, without significantly changing the Webgut. The object is achieved by the machine according to claim 1 in the loom mentioned above. The measures of the invention initially have the consequence that a laying thread can also be tied off during a transverse movement of the laying thread guide - in the weft direction. Furthermore - and this is particularly advantageous - by the distribution of the movements, namely the tying and the weft - on two movements no ligation on the fabric side of the tape fabric visible. The machine - in contrast to the weaving machine of JP 2005/015954 A - is able to apply a laying thread without noticeably altering the weaving material. Characterized in that the weaving machine in addition to and independent of the laying device for at least one laying yarn has a Kettlegevorrichtung with a plurality of juxtaposed Kettlegegliedern for laying additional warp yarns, the disadvantage of JP 2005/015954 A is avoided that the Legefäden part of the background fabric and thus change the structure. It is also very advantageous that the laying yarn can be moved and laid in any laying position between the warp-laying members on the tape fabric.

Advantageous embodiments of the loom are described in the dependent claims. It is advantageous if the Kettlegevorrichtung has transverse movement means by means of which it is movable transversely to the warp threads when it is not immersed in the shed. According to an advantageous embodiment of the present invention, the laying device has at least one further laying yarn guide, which is arranged in the warp direction behind said laying yarn guide and is movable transversely to the warp direction. According to a further embodiment of the present invention, the device has at least one retaining hook which can hold the laying thread when the reed is bruised. In this case, the retaining hook is guided so that it is movable away from the tape fabric in an initial position after the laying of the load. The abovementioned embodiments initially relate to ribbon looms. On wider weaving machines, the inventive technique can advantageously be used in that several Kettlegevorrichtungen are arranged parallel to the selvedge side by side at a defined distance. Preferably, the Kettlegevorrichtungen are driven coupled. For certain applications, it may also be advantageous if individual drives are provided, so that the Kettlegevorrichtungen are driven individually and independently controlled.

The above-mentioned, as well as the claimed and described in the following embodiments, to be used according to the invention elements are subject to their size, shape design, material use and their technical conception no special conditions of exception, so that the well-known in the respective field of application selection criteria can apply without restriction.

Ways to carry out the invention

 1 shows a loom according to a first embodiment of the present invention, as a schematic representation for explaining the basic movement. The warp threads 2 for producing a tape fabric 10 form for entry of a weft thread by means of a weft insertion needle 7 or a gripper - in a rapier - a top compartment 5 and a lower compartment 4. A reed 1 is arranged in a conventional manner to the registered weft threads to the already created Webgut 10 to strike.

The Kettlegevorrichtung 9 dives through the upper compartment 5 in the lower compartment 4 a. At the same time, the reed 1 moves backwards. The Kettlegevorrichtung 9 can be moved in the direction of reed 1 as well as down in the lower compartment 4 become. The Kettlegevorrichtung 9 follows in the illustrated embodiment of the movement of the reed 1. The Kettlegevorrichtung can also be switched off or can be submerged as often as required depending on the binding. The shot of the weft insertion needle or the gripper 7 crosses the additional warp threads 8, if the Kettlegeglieder are in the lower compartment. The shot of the weft insertion needle 7 or the gripper is tied off in the illustrated embodiment by means of an auxiliary thread. The Kettlegevorrichtung 9 emerges the Kettlegeglieder from the lower compartment 4 and the upper compartment 5 and moves with the reed 1 in the starting position 11. Thereafter, the additional warp threads 8 - in the illustrated embodiment, fixing threads - struck by the reed 1. The warp must be laid out so that it is never tied to the shots. In Figure 2, the additional laying is explained by means of a Lefleadenführers. The Legefadenführer 13 for the laying yarn 12 can be brought by a transverse movement in each laying position between the Kettlegegliedern 14. This is followed by the basic movement described above according to FIG. 1. The laying thread 12 can be an effect thread, eg wires, bead cords, elastic threads, etc., or else a functional thread, eg a thread. As an LED thread, conductive thread, etc. be.

When the warp-laying device 9 is in the home position 11, the laying yarn guide 13 can be moved between the warp-setting members 14 to the new laying position, e.g. by means of a linear motor, a cam gear, etc. This can - depending on the desired effect and function - be done periodically or according to a freely defined pattern.

With the additional chain, so the fastening threads 8, the laying thread 12, especially in the weft direction, tied to the tape fabric 10. The further chain 8 - in the described embodiment Befestigungsfäden- may alternatively or as an additional effect, a chain of effect threads. The warp-laying apparatus 9 can also be displaced in the transverse movement by one or more warp-setting members 14 in order to lay and bind a laying yarn 12 in the warp direction of the band fabric 10. This allows new patterns and effects. The Kettlegeglieder 14 are arranged in a fixed, in the present embodiment the same distance next to each other.

According to a further embodiment of the present invention, which is shown in FIG. 3, a plurality of laying yarn guides can be lined up in succession.

Each Legefadenführer 13, 16 is operated by a separate drive and can be moved independently in the transverse direction.

On this loom, the Legefäden 12 and 15 can be crossed and it can be achieved as new effects.

A further embodiment of the invention is shown in FIG. In this embodiment, a retaining hook is used.

The retaining hook 17 holds the laying thread in order to reduce the load on the additional warp thread 8-in the exemplary embodiment of a fastening thread. The movement of the retention hook can be done via rotation as well as a linear movement. It can be used on a weaving two or more members 18 in the retaining hook. Once the laying yarn 12 has been laid, the retaining hook 17 again moves away from the tape fabric 10 to its original position or remains in position until the laying yarn 12 has set.

FIG. 5 shows a weaving machine according to an exemplary embodiment with the use of three side-by-side warp-laying devices 9 operating in parallel. The Kettlegevorrichtungen correspond to those in the embodiments described above and are not shown for clarity in Figure 5 again. On such a wider weaving machine, the inventive technique is advantageously used in that several Kettlegevorrichtungen 9 - in the illustrated embodiment just three - are arranged side by side parallel to the selvedge at a defined distance. In the illustrated embodiment, it is indicated here, several bands are made in parallel next to each other. If the belts are similar, solely to increase the rate of production, the warp knitting devices 9 are driven coupled thereto. For certain applications, for example if differently configured bands are to be produced side by side or if different applications are to be produced on a wide web 10, it may also be advantageous if individual drives are provided so that the warp-laying devices 9 are driven individually and independently of one another.
