Description

   Distance fabric, method for forming the distance fabric, and loom for performing the method   

The invention relates to a distance fabric comprising two outer fabrics and a plurality of entanglement lines connected to the outer fabrics and arranged between the outer fabrics.

In addition, the present invention relates to a method for forming a distance fabric, which comprises two outer fabrics and a plurality of intertwined yarns connected to the outer fabric and disposed between them. The distance fabric is formed from a two warp system, and a warp The thread system is to weave two pieces of outer fabric, and the other warp system is to pull out the knotted warp thread from the shed to the gap between the two pieces of outer fabric during the interruption of the knitting process to form a knotted thread.

In addition, the present invention relates to a weaving machine to perform the above method, including two warp systems, one of which is used for weaving the outer fabric and the other of the warp system is used to form a loop of a knot, and further includes a comprehensive The system of shafts forms a shed associated with the weft insertion mechanism, and a beating mechanism that pushes the weft thread to push the inserted weft thread to a beating point where the fabric is taken up from the take-up wheel.

US Patent No. 8,015,999 B2 discloses a loom for manufacturing three-dimensional three-dimensional distance knitted fabrics, hereinafter referred to as a distance fabric (sometimes referred to as a distance fabric). The distance fabric includes two outer fabrics connected to the two outer fabrics Fabric and a plurality of inter-yarns disposed between the two outer fabrics. The loom includes a two-warp system, one of which provides for weaving two pieces of outer fabric and the other forms a spacer yarn during the interruption of the knitting process, so that during the weaving, its warp yarn system is knitted into two pieces of outer fabric. The spacer yarn is formed by intersecting the warp yarns forming the spacer yarn in the shed area after the weaving process is interrupted, and the raising means of the spacer yarn is inserted into the shed and parallel to the weft. Enter direction. In order to form the spacer yarn, the yarn lifting device moves forward from the shed between the two outer fabrics. Therefore, depending on the speed at which the spacer yarn is drawn, the relevant warp thread needs to be Released twice. Once the spacer yarn is pulled out of the desired length, the knitting process begins again. After the subsequent weaving process is interrupted, the yarn lifting device for the spacer yarn is pulled out from the gap between the two outer fabrics, and is placed again in the shed to allow the spacer yarn to pass between the two outer fabrics. An embodiment of the yarn lifting device is disclosed in FIG. 1 ′ of the US Pat. No. 8,015,999 B2 patent, which is formed by a bar provided in the shed, so the bar system enters from both sides of the shed, and its The length is greater than the width of the outer fabric from the fabric. After the spacer yarn is pulled up, the yarn lifting device is ejected from both ends of the shed. Although the drawn spacer yarn loops are clamped between the two outer fabrics, the spacer yarns are loosened at the outer edges of the two outer fabrics due to the impact of the weaving. In addition, the two outer fabrics may move relative to each other due to the overall thickness of the distance fabric, making it difficult to wind the distance fabric on the clothes rail.

In US Pat. No. 8,015,999 B2, a movable back rest is used to release the warp threads to pull the spacer yarns. Since the back beam swings at a specific angle, the desired length of the warp yarns is released. This solution is very difficult to implement on a loom, especially when considering the weight of the rear beam and the physical conditions of the arm length. Another problem is that in order to maintain the warp tension, it must be preset during the reverse movement of the back beam. After the spacer yarn is drawn, the knitting process is resumed. When the warp system of the spacer yarn is drawn, the margin time of the other spacer yarn is drawn. In order to maintain the knitting tension, the knitting time to the next interruption is usually 5 to 20 seconds.

Because the knitting process is interrupted to pull the spacer yarn, the steps of inserting and pulling the spacer yarn lifting device, pulling the spacer yarn, and releasing the warp to form the spacer yarn can be performed manually.

Distance fabrics A distance fabric having a length of spacer yarns to 100 cm can be produced by the above-mentioned manufacturing method, but the productivity is low and at least three workers are required.

An object of the present invention is to provide a distance fabric which does not have the above-mentioned disadvantages, to provide a method for automatically forming a distance fabric using only a loom method, and to provide a loom to efficiently perform the method.

The object of the present invention is achieved by the distance fabric, which is mainly formed by the outer fabric with a hollow portion of the distance fabric and filled with loops of the splicing line, and the two sides of the distance fabric are terminated with a fabric edge without the splicing line, which The cloth edges are connected to each other to close the cavity from the fabric. The edge of the cloth and the width of the hollow part of the loop containing the stitching line define the gap that the joystick can move when the loop of the stitching warp is pulled out. Grab, that is, outside the area forming the loop of the knot line. The outer selvedge prevents slack in the loop from outside the fabric cavity, allows the fabric to extend on the loom in a conventional manner, and prevents it from moving relative to other outer fabrics when the outer fabric arms are picked up and entangled. Preferably, the outer cloth edge can also be used to extend and guide the distance fabric during the subsequent and mainly completed technical operations, such as: rewinding, coating, and opening.

The distance fabric can also be manufactured as a double-layer fabric without an outer fabric edge, wherein the outer fabric forms hollow portions of the distance fabric filled with loops of stitching lines on both sides and terminates with a fabric edge without the stitching lines.

In addition, the object of the present invention is achieved by a method of forming two outer fabrics and a distance fabric in which a plurality of splicing threads are connected to the outer fabric and disposed therein. The distance fabric is formed by two warp systems. One provides only two pieces of outer fabric, and the other provides two pieces of outer fabric. During the interruption of the knitting process, the knotted warp thread is pulled out from the shed by the pulling device of the knotted warp thread. The gap between the fabrics, and thus the principle of this method involves inserting the lever of the knotted warp thread pull-out device into the shed from the side of the shed after crossing the knotted warp threads in the shed during the weaving interruption. In order to form a loop of the splicing line, the joystick is a method in which the electromagnet is placed above the upper and outer fabrics, and the half of the defined length of the splicing line is preset, and the distance between the upper and outer fabrics is taken up inward. Direction shift. The weaving cycle to form the upper and lower outer fabrics begins. During weaving, the joystick system moves in the direction from which the fabric is taken up at the same speed as the fabric is taken up. After a predetermined number of warp threads are inserted and knitted, the weaving cycle is interrupted and the joystick of the device used to pull out the knotted warp is returned to the shed and moved in the direction opposite to the direction of the fabric winding, and then the joystick is removed from the shed One side was taken out, and the knotted warp threads were crossed, and then inserted into the shed. This method allows only the weaving machine to form a selvage that includes a distance fabric with a loop of spliced threads to close the hollow portion of the thread with a selvage and a distance from the fabric to a hollow portion of the loop that closes the spliced threads. Therefore, the cloth edges are connected to each other by closing the outer cloth edges of the hollow portion of the fabric.

The action of releasing the knotted warp threads to form a knotted loop during the action of the pulling device is achieved by increasing the rotation speed of the relevant warp beam. The speed of the release action is twice the moving speed of the joystick.

In order to manufacture the fabric according to the present invention, the selvage is formed on the edge of the hollow portion of the fabric on the two outer fabrics during the weaving cycle, and the hollow portion of the distance fabric with the loop of the stitching line is formed therebetween.

In a preferred embodiment, two pieces of outer fabric are joined together at the back side of the cloth edge to form an outer cloth edge, and the length of the traction device of the warp stitch is smaller than the distance of the outer cloth edge and larger than the loop with the stitch line. The width of the hollow part of the fabric.

According to the requirements of the distance fabric, the loop length of the interlaced warp can be changed during the weaving cycle and the selected weaving cycle, and can be fixed during the weaving cycle.

The bracket is provided with manipulation tweezers connected with a gripping arm for gripping the joystick, and the manipulation tweezers are coupled to the clamping device. In a preferred embodiment, the bracket is coupled to a linear actuator including a linear actuation unit, and a support portion is provided on the support for reversible displacement and return toward the shed. The support portion is provided with a bracket.

In order to guide the joystick into the insertion mechanism, a stable guide is provided in the support contour.

In order to guide the joystick in the shed, lamellas are installed on the batten, and the upper surface of the lamellas constitutes a guide track of the joystick.

The position of the joystick at the shed is coupled to at least two electromagnets installed on the beam, and the tail end of the beam is installed on a linear actuator synchronized with each other along the side of the machine. The linear actuator is provided in the weaving area and Winding is away from the outside of the fabric area, so that the linear actuator ensures that the cross beam can be reversely shifted in the direction of the winding action of the fabric and returned to the shed.

As shown in FIG. 1 and FIG. 2 of the embodiment of the present invention, the loom for weaving a distance fabric includes a system of an upper warp beam A0 and a bottom warp thread 1. The upper warp beam A0 is coupled to an upper warp beam driven by a conventional electrical warp controller (not shown). Below the upper warp beam A0, there is a first rotating rear beam side wheel A2 of the bottom warp and a second rotating rear beam side wheel A4 of the bottom warp. Between the two, it is provided to sense the tension of the bottom warp 1. Full-width induction lever A3. The primer warp 1 is guided from the second rotating rear beam side wheel A4 to the heald shafts L1, L2, L3, and L4 to form a shed to weave the upper outer fabric T1 and the lower outer fabric T2. The heald shafts L1, L2, L3 and L4 are mounted on the machine in a conventional manner and are coupled to a conventional dobby loom (not shown).

A lower warp beam B0 is provided at the lower part of the machine, which is tied to the warp system 2 provided with the entangled warp. The lower warp beam B0 is coupled to the lower warp beam driven by an electric warp controller (not shown), which is adapted to two modes of operation, that is, weaving, and when the warp 2 is When pulled to the gap between the outer fabrics T1, T2, the warp threads 2 are released at high speed. A rotating back beam side wheel B2 is provided above the lower warp beam B0, and the splice warp 2 is guided to the rigid connecting rod B4 from the beam side wheel. Between the rotating rear beam side wheel B2 of the spliced warp and the rigid connecting rod B4, a full-width induction bar B3 of the spliced warp 2 is provided. Between the back beam side wheel B2 of the knotted warp and the rigid connecting rod B4, a full-width induction lever B3 is provided to sense the tension of the knotted warp 2. The spliced warp threads 2 are guided from the connecting rod B4 to the heald shafts L5 and L6. During the knitting process, the intertwined warp 2 is woven with the base warp 1 into upper and lower outer fabrics T1, T2, and during the interruption of the weaving, the intertwined warp 2 is pulled to the outer fabric T1, A gap between T2 to form an entanglement line 200 from the fabric T. The system of setting up the warp warp 2 on the lower warp B0 is obviously more advantageous, because the consumption of the warp warp 2 is more than the consumption of the bottom warp 1, and replacing the lower warp B0 is better than replacing the upper Warp A0 is easier. However, the system for priming warp 1 and the system for tying warp 2 can be reversed.

It is described in a specific embodiment that it is mentioned that six axes such as L1 to L6 are used, wherein the first four axes L1 to L4 are provided for guiding the warp 1 to form the woven upper and lower fabrics T1 and T2. Shed (P), and the remaining two axes L5 and L6 are used to guide the entangled warp 2. However, these axes can be assigned at will, for example, the first two axes can be used to guide the suture warp and the remaining axes can be used to guide the base warp. The number of shafts can be more than six, so additional shafts can be used to form outer edges or outer cloth edges, which are connected to two outer fabrics and to prevent their relative movement, or to produce more complex outer fabrics T1, T2 Weaving. The six-axis embodiment is a basic embodiment to form an open-edge distance knitting fabric T with an entangled loop 200 without cloth edges, or a distance knitting fabric T having a hollow portion. In the present invention, this embodiment is first explained to better understand the principle of the present invention.

The shed P is related to the conventional picking mechanism 3, and includes an air jet picking nozzle and a transfer nozzle arranged along the length of the shed, and a conventional contour knitting reed line The beating mechanism 4 is inserted into the reed seat 42 of the weft thread 5 to the beating point 6. As shown in the embodiment, the lamella 41 is a pedestal 42 disposed between the transfer nozzles. The sheet 41 is formed in the shape of a processed wire or a flat sheet, and a guide rail 410 that guides the joystick 71 to the shed (P) is formed on the upper surface thereof. From the beating point 6, the distance fabric T is wound across the front beam 61 and the electrical control reel C3 above the rigid connecting rods C1, C2. The distance fabric T passes from the take-up wheel C3 through the pressure beam wheel C4 and the rotation wheel C5 to a conventional large-knit winding wheel (not shown). The device 7 for pulling the knotted warp thread 2 to the gap T0 between the upper outer fabric T1 and the lower outer fabric T2 during the weaving interruption includes a joystick 71 made of a lightweight and high-strength material, which is attached to the stitching The knot warp thread 2 is set before the intersection of the spliced warp thread 2 before the shed P starts to be drawn. The knot warp thread 2 is knitted into the upper outer fabric T1 and the lower outer fabric T2. The joystick 71 is coupled to at least two electromagnets 72, and the electromagnet 72 is displaceably disposed above the upper and outer fabrics T1 according to the fabric width on the beam 73 and the length of the joystick 71, as shown in FIG. The end point of the beam 73 is mounted on a linear drive 74, which is placed outside the knitting area on the side of the machine, or more specifically, outside the winding area of the fabric T. The linear drivers 74 are synchronized with each other. A special embodiment is shown in FIG. 3. The linear actuator 74 is formed by a linear actuator unit 741 together with a precision ball screw. The linear actuator unit 741 is coupled to the synchronous servo motor 743 by transferring the belt unit 742. The synchronous servo motor 743 is a device coupled to the control system of the loom to synchronize the movement speed of the beam 73 with the spliced warp during the loop T0 of the spliced warp 2 is pulled to the gap T0 between the outer fabrics T1 and T2. 2 is the speed of movement from the warp beam B0, and the operating speed of the beam 73 is synchronized with the winding operation speed of the distance T from the fabric T during the weaving. The above-mentioned embodiment can be implemented by other suitable embodiments to ensure that the actions of the linear driver 74 are accurately synchronized, and provide an appropriate force to pull the knotted warp 2.

The electromagnet 72 is a device controlled by pulse width modulation and coupled to the control system of the loom.

The joystick 71 has at least one ferroelectric component or a permanent magnet (not shown in detail) at a point where it can be coupled with the electromagnet 72, which allows the joystick 71 to be grasped by the electromagnet 72. At one end, the joystick 71 has a tail piece 711 to be grasped by the manipulation tweezers 84 of the insertion mechanism 8 of the joystick 71. It is theoretically feasible to manufacture the entire joystick from ferroelectric material to ensure that it is coupled to the electromagnet 72, but since this will greatly increase its weight, such an embodiment is not suitable for the actual production process.

In the illustrated embodiment, the insertion mechanism 8 of the joystick 71 is rigidly mounted on the machine frame, and on the shed P on the opposite side to the weft input mechanism 3, as shown in FIGS. 2, 18 and 21. The insertion mechanism 8 contains a support profile 81 which is rigidly mounted on the machine frame in various known ways. The linear actuator 82 is mounted on the support contour 81 and is formed by a linear actuation unit 821 and a support 822 in the embodiment. The power chain 89 is a support profile 81 provided beside the linear actuation unit to guide the supply of compressed air to the air cylinder 87 of the clamping device 85. The linear operating unit 821 is coupled to the synchronous servo motor 823 through a coupling (not shown). The bracket 83 is connected to the support 822 of the linear unit 821 and is reversibly displaceable and returnable to the shed P. The operating tweezers 84 are mounted on the bracket 83. The front of the operating tweezers 84 are provided with clamping arms 841, 842 controlled by a clamping device 85, which are controlled by Bowden cables and steel cables coupled to the cylinder 87 in the embodiment. The stability guide 88 of the joystick 71 is formed on the support contour 81 to stabilize the joystick as it moves from or to the shed P. This particular embodiment may be replaced by other suitable embodiments that provide reliable required functionality.

The upper beam 9 extends along the full width of the machine. As shown in Figs. 2, 18, and 19, the upper beam 9 is provided on the upper part of the machine on the upper and outer fabrics T1. The upper pressure supporting beam rod 91 is reversibly and replaceably mounted on the upper beam 9 toward the upper outer fabric T1 and the back side. As shown in the embodiment, the upper pressure support rod 91 is controlled by a device of a pressure cylinder 92, and the pressure cylinder 92 is installed on the upper beam 9 together with the brake cylinder 93, and a brake pin 94 is attached to ensure that the lever 71 The position before being grasped by the tweezers 84 and extending beyond the shed P, after being inserted into the shed p again, and before being grasped by the electromagnet. The pressure brace rod 91 is provided to press the upper outer fabric T1 toward the front beam 61.

When the distance fabric T is knitted at the beginning, the two outer fabrics T1 and T2 are woven from the base warp 1 and the entangled warp 2 and at least half of the base length of the yoke 200 corresponding to the distance fabric T is woven. The length is usually longer at the beginning. When the base length is knitted, the knitting process will be interrupted, the shed P will be opened, the junction warp 2 will cross, and the joystick 71 is inserted into the shed P on the guide track 410 by the insertion mechanism 8. After the insertion, the position of the joystick 71 is fixed by inserting the brake pin 94 into a fixing hole 712 formed in the joystick 71. Next, the electromagnet 72 is shifted above the joystick 71. As long as its magnetic pole piece exceeds the receiving point of the joystick 71, a current will be provided and the electromagnet will start to brake the joystick 71. Synchronously, the brake latch 94 extends rearward and the joystick 71 is released. The electromagnet 72 is carried by the beam 73, which is coupled to the linear actuator 74 on both sides, and starts to move in the direction of the fabric take-up action, and is magnetically engaged by the electromagnet. Grab the intertwined warp threads 2 at the intersection and begin to pull them between the upper outer fabric T1 and the lower outer fabric T2 to form a loop of the intertwined line 200 between them. Simultaneously with the operation of the electromagnet 72, the junction warp 2 starts to release synchronously, so that the release speed thereof is twice that of the electromagnet 72. The quick release system of the knotted warp thread 2 has not been described in detail. It must relax the knotted warp thread 2 by more than 500 millimeters in a short time of about 2 seconds. At the same time, the knitting mode must ensure the required tension of the knotted warp thread 2, Through the full-width induction lever B3, the magnetic warp controller (not shown) and the control system of the loom are controlled so that the entangled warp threads 2 can be smoothly knitted into the respective outer fabrics T1, T2. Once the electromagnet 72 reaches the preset position from the control system of the loom or from the pre-programmed pattern from the fabric T, the electromagnet 72 stops but continues to hold the joystick 71 firmly.

Next, when the upper pressure cylinder 92 is moved again to contact the upper outer fabric T1 and the weaving is started, it is advantageous to position the healds L1 to L6 and execute the beating cycle of the beating mechanism 4 before weaving. The weaving process is performed in a conventional manner by weaving two fabrics, one of which is set on the other fabric, or by weaving a double hollow fabric. The two outer fabrics T1, T2 are knitted from the base warp 1 and half of the interlaced warp 2 are knitted to each outer fabric T1, T2. The knitting process is shown in Fig. 3 and Fig. 4, wherein Fig. 3 shows the insertion of the weft thread 5 and Fig. 4 shows that the weft thread is beaten to the beating point 6. During the weaving, the electromagnet 72 is set at the same speed as the distance T take-up action of the fabric, and the fabric take-up action direction is set during the weaving, and the lever 71 is still maintained, which keeps the knot line 200 in the extended position and prevents it from returning Or entangled.

After weaving a predetermined length from the fabric T, the outer fabrics T1, T2 are set from a pre-programmed pattern, or after a predetermined number of weft insertion and knitting warp threads 5, the knitting process is interrupted. After knitting is completed, at least one stable beating is performed. The upper pressure brace rod 91 is separated from the upper and outer fabric T1 at a distance, and the reed line 43 and the heald shafts L1 to L6 of the beating mechanism 4 are set to the desired position to open the shed P to create the joystick 71. There is a free space with the reed line of the beating-up mechanism 4 so that the joystick 71 can reversibly move, see FIG. 5.

The electromagnet 72 still holds the joystick 71, and moves from the end of the knitting position to the space of the shed, as shown in FIG. 5, and places the joystick 71 on the guide track 410 to form the beating mechanism 4 The upper cymbal 42 is shown in FIG. 6. At the same time, the outer part T11 of the upper and outer fabric used for weaving the upper and outer fabric and a part of the warp are still clamped between the joystick 71 and the electromagnet 72, and remain between the upper and outer fabric T1 and the respective warp Below the height. The splicing thread 200 pulled by the joystick between the two outer fabrics T1, T2 still maintains its position.

By lowering the brake latch 94 to the fixing hole 712 of the joystick 71, its position is fixed as shown in FIG. 7, the joystick 71 is simultaneously released from the electromagnet 72, and the joystick 71 is placed on the guide track 410. The electromagnet 72 is shifted to the waiting position in the direction in which the fabric T acts, which allows the upper pressure brace rod 91 to move toward the upper and outer fabric T1, as shown in FIG. 8.

Next, as shown in FIG. 9, the insertion mechanism 8 of the joystick 71 is actuated, the tweezers 84 grasp the joystick 71 by the locking of the tail piece 711, and lift the brake latch, and then pull the joystick 71 Shuttle port P is shown in Figure 10.

Next, referring to FIG. 11, in the manner of individual healds, the healds L5 and L6 in the embodiment pass over the entangled warp threads 2 previously woven into the upper outer fabric T1 and the lower outer fabric T2, and the warp threads can penetrate through The knitting shaft 43 of the weft mechanism 4 is in a stable position.

Next, see FIG. 12. The insertion mechanism 8 returns the control lever 71 to the guide track 410 in the shed. The position of the control lever 71 is fixed by the brake pin 94. See FIG. 13, the control lever 71 The system is released from the tweezers 84, and the insertion mechanism 8 tweezers 84 returns to the waiting position.

The upper pressure brace rod 91 is lifted, see FIG. 14, so that the upper and outer fabrics T1 are straightened to form a gap between the upper and lower outer fabrics T1, T2.

Next, referring to FIG. 15, the electromagnet 72 is shifted above the joystick 71, and once the magnetic pole piece reaches a position above the receiving point of the joystick 71, a current is supplied and the electromagnet pulls up the joystick 71. Synchronously, the brake latch 94 extends rearward and upward and releases the lever 71.

The electromagnet 72 together with the joystick 71 is shifted to the intersection of the spliced warp threads 2 and then shifted between the upper and lower fabrics T1, T2 by a predetermined distance to form a loop of the spliced wire 200 therebetween, as described above. Refer to Figure 16.

Next, as shown in FIG. 17, the upper pressure brace rod 91 is shifted to the upper outer fabric T1, and it is pushed to the front beam 61 to start another weaving cycle.

As described above, the embodiments described so far are only related to the actual production of the open-distance fabric T including two pieces of outer fabric T1, T2, and the loops of the plurality of splicing threads 200 are connected to the outer fabric T1, T2, and Set between outer fabrics T1, T2, the distance fabric T is formed by two warp systems, one of which only provides two pieces of outer fabrics T1, T2, and the other is by interlacing the warp during weaving interruption The thread 2 is pulled out of the shed P to the outer fabric T1, T2 to form a loop of the spliced thread 200. Of course, it is possible to produce a product made according to the present invention, but its disadvantages are that the loops of the splicing thread can protrude outside of the outer fabric through the open edges, and that two pieces of outer fabric can be opposed to each other when they are wound around a large winding wheel And mobile, as described in the judgment of the prior art.

Therefore, in the actual embodiment, the distance fabric T is formed between the outer fabrics T1 and T2 as shown in the schematic diagram in FIG. 22 and the cross-sectional view of the fabric width in FIG. The fabric T1, T2 are staggered from the hollow portion TA of the fabric, and the outside thereof is fixed to the cloth edge TB, which extends from the cavity of the hollow portion TA of the fabric. The cloth edges TB of the cavity extending from the hollow portion TA of the fabric are joined to each other at their edges to form an outer cloth edge TC to close the cavity. The interlaced points of the splicing line 200 with the upper and outer fabric T1 are drawn in solid lines as shown in FIG. 22, and have a pattern interval TD of the fabric according to the stylized distance. According to the stylized distance weaving pattern, the length of the splicing line 200 is twice the interval TD and can be a fixed variable. If the length of the splicing line 200 is a variable number, the length of the subsequent rows of the splicing line 200 can be the maximum to the previous interval. TD twice.

The width of the hollow portion TA of the fabric from the distance between the selvage TB and the loop containing the splicing thread 200 defines the gap between the upper outer fabric T1 and the lower outer fabric T2. When the joystick 71 pulls the splicing thread 200 out of the shed P to the interval TD between the upper and lower fabrics T1, T2, the joystick 71 moves within the above-mentioned gap and returns to the shed P. The selection value of the length of the joystick 71 is therefore smaller than the sum of the width of the hollow portion TA of the fabric and the two cloth edges TB, that is, TB + TA + TB. The electromagnet 72, as shown in the embodiment, is arranged on the upper outer fabric T1 on the cloth edge TB. This setting is advantageous only if the electromagnet pulls the joystick 71 up without the spliced wire 200 wire loop, and it is placed on the upper outer fabric T1. The cloth edge TB is a part of the cavity, and the width of the hollow portion TA of the fabric including the splicing line 200 is accurately and precisely defined. After cutting a part of the cloth edge TB and the outer cloth edge TC on the final product, the hollow portion That is, the distance fabric T is formed.

The outer fabric edge TC closes both sides of the chamber, strengthening the product in a conventional manner and providing guidance and extending the fabric as part of the finished fabric until it is processed to the final product. However, these parts are not cut off from the distance fabric T until further processing to the production product.

In order to produce the above-mentioned distance fabrics with selvedges, the loom is provided with an additional heald shaft L, at least four of which are closed with a woven fabric edge TB, and at least two, preferably four, heald shafts. Close the two sides of the chamber with a woven cloth edge TC. In the case of weaving the fabric edge TB from the base warp 1 only, no additional heddle is required.

In an embodiment (not shown), the hollow portion TA of the distance fabric including the loops of the spliced line 200 may terminate only its two ends with the cloth edge TB, and thus a hollow distance fabric having the cloth edge TB is produced. There is no loop of the junction line 200 between the side TBs.

FIG. 23a shows the formation of the gap T0 between the upper outer fabric T1 and the lower outer fabric T2 when the loops of the splicing thread 200 are actuated in the operating direction of the fabric take-up by the lever 71 during the manufacturing process of the distance fabric T. The finished product of the distance fabric T is shown in Fig. 23b in an unfolded state, and the junction line 200 extends between the outer fabrics T1 and T2.

The invention is only used in a knitting machine to make a distance fabric.
