Description

at The invention relates to a method for introducing itself partially in the fabric width additionally extending weft threads while of the machine weaving process using additional ones Thread guide elements for partial tissue patterning, wherein the weft threads in the for that educated and over the fabric width in size and location by appropriately suitable technical devices arbitrarily recoverable partial Kettfadenfächern, whose individual widths are each smaller than the fabric width, be registered.

method of this kind are used for the production of pictorial tissue surfaces, such as for example the production of textile wallpaper or the production of reconstructions such needed. But also for the production of technical textiles with partially required arrangement of special functional threads in a fabric structure, this method is applicable.

It is already known that additional Threads during the area Education can be incorporated into a fabric base. In doing so, the fabric basis becomes woven mostly in plain weave or satin weave or it acts a leno fabric. These additional threads run predominantly in the weft direction. The special feature is that these additional Threads do not have the entire width of the fabric run but only one Part of the tissue width, thus forming partial patterns on the tissue surface. The pattern-forming threads be while tissue production in addition inserted in the fabric base on the loom.

Would the additional Threads removed become, then the basic fabric remains as a fabric. For the patterned entry the additional Threads is the binding-appropriate lifting and lowering of the warp threads required. This can about one Jacquard machine (large Repeats, arbitrary figures such. B. flowers) or over a Dobby (small reports, simple figures like rectangles) will be realized.

It can not, for the Entry of the partial shots to use the entry system of the basic shot. Here are special Weft insertion means, usually spools or boats necessary, on the a length limited Thread stock is wound and the hand additionally in the desired Rapport be introduced.

The Production performance is very low. These are shuttle looms with jacquard device for patterned warp thread lift.

A A special feature are the Rossbacher brocade fabrics. These were on handlooms Woven with Jacquardeinrichtung, however, to the entry of additional threads (Brochure threads) one Broschierlade (Ringbroschierlade) was used. Mostly weave two weavers together. One serviced the loom and worried for the Entry of the basic shot, the other operated the brochure tray. The brochure holder carries a certain number of bobbins with broaching threads. For the pattern thread entry can they are pivoted and placed just above the tray. In the case, that over several basic shots If no pamphlet thread is entered, the booklet holder will go up lifted. The coils are on horseshoe-shaped straps (Ringbroschierlade), the are rotatably mounted and can run the spool through the brochure tray. The not closed rings get their movement through a toothed push rod. The warp threads of the booklet compartment slip into the area of the horseshoe. About sheets it is achieved that the edge threads also slide safely into it. These edge threads are important for the formation of the contour of the figure. The bobbin with the broaching thread slides through the compartment (rotation by approx. 330 °), reverses at the reversal point and slides after the tray has been changed back through the compartment to the starting position. The thread gets its traction through inertia the coil. It is important that the rotation of the wearer is sufficient happens quickly. That's also why two weavers weaved together, one the ground fabric and a pamphlet shot. At the Ringbroschierlade the coil is attached to a non-closed ring passing through the movement of the toothed push rod with the coil once each right and turned left. This brochure tray is for the smallest To apply figures.

By an overall shift of the brochure tray can be the Brochéeffekte in misalignment. However, it is not possible outside the ring area of the Ring coil additional Threads during the To bring in tissue production. The pattern to be achieved is through the size and the Number of ring coils restricted or subject to considerable technical restrictions. A pictorial Design, as it was possible with the Handbroschieren, is not now more given.

Around however reconstructions of old brocade fabrics on machine To be able to produce ways In order to save costs and time, can on this well-known brochure method not back be grasped.

It is therefore an object of the invention to develop a method by which it is possible is to partially introduce in the fabric width additionally extending weft yarns during the machine weaving process using additional yarn guide elements to achieve a partial and individual fabric patterning. In this case, the weft threads in the formed and over the fabric width in size and location by appropriately suitable technical devices arbitrarily recoverable partial Kettfadenfächern whose individual widths are each less than the fabric width, can be entered. It should be achieved that individually designed pictorial patterns on a fabric can be additionally woven without the Eintagslängen this weft threads, which can sometimes be very valuable, must be extended over the entire fabric width.

According to the invention Problem solved by the features of claim 1. The advantageous embodiments are described in the subclaims.

After that The introduction of partially in the fabric width additionally extending weft threads during the machine weaving process by having one in the entry direction the partially formed Kettfadenfach each arranged thread guide element the additional weft thread through the partially formed Kettfadenfach guided while being spread in the same, while the second in the insertion direction the additional weft thread behind the partial Kettfadenfach arranged Thread guiding element takes over the additional weft, wherein for adjusting the entry length of the additional weft yarn to the width of the respective partially formed Kettfadenfachs control technology the thread guide element on the entry side in front and the thread guide element on the discharge side behind the partially formed Kettfadenfach independently in dependence of the respective Kettfadenfachbildung can be positioned and both thread guide elements are able to spread the partially formed Kettfadenfach Additional weft yarn until its sufficient binding Fixation in the tissue at their respective flank of the partially formed Kettfadenfaches to keep.

to better and more variable design of pictorial representations on a fabric surface to be produced at the same time, it is advantageous if the partially formed Kettfadenfach by a group of side by side liftable warp drawers is formed, with the additional weft thread through each before a warp shed group arranged yarn guide element is spread.

to Propagation of the additional weft yarn in the partially formed Kettfadenfach there is a possibility in that of at least one thread guide element from an additional weft reserve by the partially formed Kettfadenfach is performed, which is a multiple the amount of thread contains, as for each entry of an additional weft thread required is.

alternative it is possible to that of at least one thread guide element for spreading the additional weft yarn in the partially formed Kettfadenfach from an additional weft reserve the beginning of an infinite Additional weft taken and through the partially formed Kettfadenfach guided becomes.

In this variant, it is also possible that the additional weft thread comes in the form of a loop in double parallel extension to propagate by his previous binding site by the yarn guide element in a free thread extension next to the partially formed Kettfadenfach ( 13 ) is held, this thread detected in the region of its free extension, further led to the discharge side of Kettfadenfaches and held there to its sufficient binding fixation by the yarn guide element.

This can also be realized by the additional weft in shape a loop in double parallel extension for propagation comes and gets the extra weft from his previous tie to a quasi infinite additional weft reserve in a free Thread extension is located next to the partially formed Kettfadenfach, through the yarn guide element is included in the scope of this free extension, by this guided through the additional subject, on the opposite side Flank of the partially formed Kettfadenfaches of a yarn guide element pass another thread guide element and while the repatriation of the a yarn guide element from the partially formed Kettfadenfach at least from the other Thread guide element is held to its sufficient binding fixation.

It is still possible that the additional weft in the area of its free extension from the yarn guide element movable by the partially formed warp shed recorded on the entry page and through this to the discharge the partially formed Kettfadenfaches is performed. In this case, the additional weft in the form of a loop in double parallel extension for propagation come by the handover of the additional weft to be spread by both partially formed Kettfadenfach mutually oppositely directed movable thread guide elements he follows.

These Previous process variants all have the advantage that for the additional weft at least one thread reservoir application finds that a quasi includes endless thread and bring in the process accordingly can.

A another variant for introducing the additional weft thread into the partial formed Kettfadenfach is that of at least one thread guide element from an additional weft reserve sections of the additional weft thread removed and passed through the partially formed Kettfadenfach, wherein the portions of the additional weft yarn that of the required integration length of the partially formed Kettfadenfachs correspond. It exists the possibility, that the additional weft in a simple extension to spread comes by the thread guide element on the entry side of the partially formed Kettfadenfaches a free Thread end from a quasi-infinite amount of additional weft threads containing Reserve ready, which is guided by the partially formed Kettfadenfach, from Thread guide element recorded on the discharge side and thus spread additional weft until its sufficient binding fixation in both thread guide elements is held. It is also possible in this variant of introducing the additional weft of the an additional weft reserve is taken, which is the connection of the additional cash weft added to the quasi-infinite additional weft reserve is separated after its sufficient binding fixation, with the thread guide element on the entry page for a later one Additional weft insertion again a free thread end is provided. Also in this variant, the advantage is that an infinite Reserve gauge Weft sections in stock can be kept, especially in a wide variety of colors and quality variants and thus an extensive scope for the introduction from a variety of additional weft threads in the fabric structure and with it for the design of the pattern possible is.

Of the Entry of the weft thread can also be via different solution variants respectively.

So there is one possibility in that on at least one of the two yarn guide elements to the entry of the additional weft yarn fluid flow in the direction of entry initiated, which transmits a kinetic energy to the additional weft, whereby it for the propagation of the additional weft yarn in the partially formed Kettfadenfach comes. Although this variant is the highest technical precision demands on the transfer component or Pick-up component of the transported additional weft yarn and it is, however, placed on the control unit of the fluid flow a very effective variant that is very flexible and fast on the individual application claims can be adjusted and while a web process to meet the most diverse requirements can be.

to support the kinetic energy of the fluid flow and to optimize the direction of movement the free end of the thread can be on the opposite side of the warp shed a kind of suction nozzle act, wherein the yarn guide element itself as a suction nozzle can be trained.

It exists however for the additional weft transport also the possibility of the movement of the thread reserve through the partially formed Kettfadenfach on a temporary in the partial realize formed Kettfadenfach located guideway. in this connection are highest claims placed on the mechanical design of the temporarily to be formed guideway. But even with this variant can be flexible during the Web process and quickly to the most varied design options and needs to be responded.

The Returning the Thread reserve before a subsequent entry can also be outside a partially formed Kettfadenfaches from the discharge side to the entry side, while the Kettfadenfachbreite restrictive on the flexibility the design options while Web process.

For all variants the introduction of a partially extending in the fabric width weft additionally while of the machine weaving process, however, that applies to the Additional weft threads For each partially formed Kettfadenfach the weft reserve in any number and in any thread quality and thread color can be provided.

As well Is it possible, that listed different Entry variants of additional weft, such as the various mechanical and pneumatic variants or the variants with the fluid stream, combined with each other or interchanged can be an effective variant for to realize the respective application.

With This method is the disadvantages of the prior art Technology overcome. There are a lot of variants created that make it possible while additional weaving threads into the weaving process Fabric structure, whereby the design scope for the pattern design, both in terms of the thread qualities to be used, as well the thread colors and / or the pattern widths, there are no limits.

The Invention will be explained in more detail below by exemplary embodiments.

embodiment 1:

According to the 1.1 , and 1.2 , the method of introducing partially weft threads additionally extending in the fabric width during the machine weaving process using additional yarn guide elements for partial fabric patterning is effected by an additionally arranged yarn guide element 1 initially receives an additional weft reserve SR, wherein the yarn guide element is formed on the Kettfadenfachbreite each positionable. The additional weft reserve SR is guided on a guide path, which is temporarily partially formed in the respective warp shed area, through the warp shed B and on the likewise positionably arranged yarn guide element 2 taken, whereby the additional weft yarn S in the warp sheath B is spread. Since the individual Kettfadenfächer B by means of suitable technical devices in their width are designed arbitrarily aushebbar, are also the thread guide elements 1 and 2 independently of the control technology, independently of each other, can be positioned so as to be positioned on the respectively formed width of the individual warp thread bins B of a warp thread group Bn. Both thread guide elements 1 and 2 fix the additional weft thread S spread out in the warp sheath until it is bound in the weave into its respective flank E or A. This process of transporting the additional weft reserve SR takes place in the next step in the reverse direction according to FIG 1.2 from the thread guide element 2 to the thread guide elements 1 ,

According to the invention, it is indispensable that, for a variable design possibility of the pattern formation, a plurality of warp thread bins Bn arranged next to one another form a warp thread bark B. The thread guide element 1 is in each case in front of a Kettfadenfach group and the yarn guide element 2 arranged according to a Kettfadenfach group and the additional weft thread is spread through the Kettfadenfach group respectively.

The wefts so be in it for that educated and over the fabric width in size and location be arbitrarily lifted by appropriately suitable technical devices partial warp drawers, whose individual widths are each smaller than the fabric width, entered.

The Additional Weft Reserve SR contains a multiple of the for one Shot needed Amount of thread and thus forms a quasi infinite additional weft reserve SR for the pattern formation.

Advantageously, this embodiment offers the possibility that several thread guide elements 1 and 2 to accommodate various additional weft reserve SR, which contain the most varied but necessary for the pattern training thread qualities and thread colors, are present and included in the weaving process.

control technology will be needed on each Additional Weft Reserve SR accessed and included in the web process or temporarily excluded from the web process.

With this variant is a solution ready, which makes it possible on customer requests to be able to respond individually, and the design variability for patterning by additionally introduced additional threads while There are no limits to a web process.

embodiment 2:

According to the 2.1 , and 2.2 , the introduction takes place partially in the fabric width additionally extending weft threads during the machine weaving process using additional thread guide elements for the partial fabric pattern formation by at least one yarn guide element 1 . 2 in that the additional weft thread S is initially from its previous binding position to a quasi-infinite additional weft reserve SR in a free thread extension S3 next to the partially formed Kettfadenfach B, through the yarn guide element 1 is received in the region of this free extension S3, is guided by this by the Kettfadenfach B and on the opposite edge, in this case A of the partially formed Kettfadenfaches B from the yarn guide element 1 to the yarn guide element 2 is transferred or taken over by this. During the return of the thread guide element 1 from the partially formed Kettfadenfach B is at least from the yarn guide element 2 the additional weft S held in its double parallel extent until its sufficient binding fixation.

There is also the possibility according to the 2.1 , and 2.2 , that the thread guide element 2 the additional weft thread S held by the yarn guide element and in its free extension S3 entry side after passing through the partially formed Kettfadenfachs by the yarn guide element 2 recorded and during its return to its output-side position this additional weft thread S in the form of a loop in double parallel extension in the warp sheath B come to propagate, the additional weft S is held at least from this to the binding fixation.

But even if both thread guide elements 1 . 2 in the partially formed Kettfadenfach 13 to move towards each other and the thread transfer / takeover takes place in Kettfadenfach B, there is a double parallel extent of the additional weft yarn S in Kettfadenfach B.

Another possibility for spreading the additional weft yarn S in double parallel extension in the partially formed Kettfadenfachs B during the weaving process is that the additional weft S of a yarn guide element 1 . 2 guided, by means of a fluid flow FE, which changes its direction after each shot, as a loop is transported through the Kettfadenfach B and on the opposite side of the other yarn guide element 1 . 2 taken up and held until binding fixing.

These Variant of the double parallel extension of the additional weft thread S within the partially formed warp shed B has the advantage that the additional weft S per shot in duplicate can be introduced into the tissue and thus, if desired, the Supported sample image can be. But it can also be used in technical applications be beneficial if the additional weft S continuous partially can be arranged in the tissue.

embodiment 3:

According to the 3.1 the auxiliary weft S is spread in a simple extension in the partially formed Kettfadenfaches B by the yarn guide element 1 at the entry side E a free thread end S4 a quasi infinite additional weft reserve SR ready, this leads through the partially formed Kettfadenfach B and of the yarn guide element 2 on the discharge side A recorded until its sufficient binding fixation in both yarn guide elements 1 . 2 is held.

After its sufficient binding fixation of additional weft S is separated on the entry side, bringing the yarn guide element 1 on the entry side E for a later additional weft entry again a free thread end S4 is provided.

However, it would also be conceivable that an additional weft reserve SR for the pattern to be introduced provides the required length sections of the additional weft thread S in a quasi-infinite large number and by the yarn guide element 1 detects a free end of an additional weft thread section and leads to the through the warp shed B and then to the yarn guide element 2 passes, whereby the additional weft S spread out in a simple extension and until its sufficient binding fixation in both yarn guide elements 1 . 2 is held.

embodiment 4:

According to the 4.1 , and 4.2 , the auxiliary weft S is spread in a simple extension in the partially formed Kettfadenfaches B by the yarn guide element 1 at the entry side E a free thread end S4 from a quasi an infinite amount of lengths of the additional weft S willingithenden additional weft reserve SR positioned so that it is detected by a fluid flow FE and guided by its kinetic energy through the Kettfadenfach. On the opposite side of the Kettfadenfachs B, the end of the additional weft thread section of the yarn guide element 2 detected and by both yarn guide elements 1 . 2 held until its sufficient binding fixation. To support the kinetic energy and defined orientation of the motion control of the auxiliary weft yarn S, the fluid flow can be acted upon by an additional, for example, volatile medium.

These Variant offers the advantage that no device elements through the warp shed must be moved through or additional cutting devices must be provided. A very efficient and cost effective Variant for the Insert partially in the fabric width additionally extending weft threads during the machine Weaving process.

embodiment 5:

According to the 5.1 , and 5.2 , the additional weft yarn S is also spread in a simple extension in the partially formed Kettfadenfaches B by the yarn guide element 1 positioned on the entry side E a free thread end S4 from a quasi-infinite additional weft reserve SR so that it is detected by a fluid flow FE and guided by the kinetic energy through the Kettfadenfach. On the opposite side of the Kettfadenfachs B is the end of the additional weft thread section of the yarn guide element 2 detected and by both yarn guide elements 1 . 2 held until its sufficient binding fixation. To support the defined orientation of the motion control of the additional weft yarn S and the optimized transfer to the yarn guide element 2 can the thread guide element 2 itself be designed as a suction nozzle or an additional suction nozzle supports the movement guidance of the additional weft yarn S during its transport through the Kettfadenfach to the yarn guide element 2 , Until its binding integration, the suction nozzle remains active. Thereafter, the cutting of the additional weft thread is cut on the input side, whereby a new thread end S4 is again the fluid flow available.

Also This variant offers the advantage that no device elements must be moved through the Kettfadenfach through. This is what this variant is also a very efficient and cost effective variant for the introduction Partially in the fabric width additionally extending weft fills during the machine weaving process.

Becomes However, by means of the fluid flow not the thread end S4 but a Loop of additional weft yarn detected and through the Kettfadenfach B transported, is also possible with this variant, the additional weft S in double extension in the warp shed per shot to bring.
