Description

  The present invention relates to a tensioning device (Spannvorrichtung), a treading machine (Fadenkreuzeinlesemaschine), a threading machine (Einziehmaschine), and a method for tensioning a plurality of warps.

  More and more, for example, weaving warp yarns such as flat plastic yarns (Kunststofffaeden, synthetic yarns) into textile materials. The fiber material produced by such a method is used, for example, for storing or storing, storing and / or transporting foodstuffs, particularly vegetables. There is a wider range of applications or fields of application in any field where high strength and abrasion resistant fiber materials or fabrics (webs) are needed, for example in the field of agriculture. The flat plastic thread is made, for example, from polypropylene. In order to weave Kettfaeden, a flat plastic yarn into a fiber material, a warp or warp yarn usually wound on a warp beam (Kettbaum, warp beam, warp beam, warp beam) And is unwound or unwound from the warp beam in a piecewise or piecewise manner during the weaving period (abgewickel).

  In the technical field of textiles, there is a method to combine the warp of the unwound warp beam (the edge tail of the warp group, the warp row at the end of the fabric (abgewebte Kette)) with the warp of the new warp beam (new warp). Are known. For this purpose, in the prior art, it is known to provide a knot or knotting or knotting frame. In this method, a warp layer (abgewebte Kettfadenschicht) reaching the end edge of the fabric and a new warp layer, The loom is pulled and flattened in two directions so as to straddle at a predetermined position or state. For this purpose, the joining frame is provided with a tensioning device for making the new side end warp row (leading portion) and / or the old side end warp row (tail portion) flat or flat. Is provided. Thereafter, a yarn binder or yarn splicer attached to the joining frame ties or splices the two layers of warp.

  The work of tensioning the new warp layer can be done away from the loom and is also independent of the weaving work, so the loom downtime is actually the same between the old and new warp layers. It depends substantially on the time it takes to tie or join. If a new warp layer is prepared in such a manner, the loom stop time can be shortened.

  For the tying operation, a joining frame, which has already been flattened with the warp of a new warp layer stretched, is introduced into the loom and passed through. The warp of the old warp layer is similarly tensioned and flattened. After the warp yarns of both the old and new warp layers are pulled in two directions at a predetermined position and flattened, they are tied or spliced together by a yarn binder or yarn splicer. Thereafter, the knot or yarn splicing frame is removed from the loom, and the operation of weaving with a new warp layer is resumed and continued. While the above-described operation of tying or joining a new warp layer to an old warp layer proceeds, in the loom, the old warp beam from which the warp is unwound is replaced with a new warp beam.

  As described above, the new warp layer is flattened by the tension device in the combined frame. The same operation is performed on the old warp layer of the loom. In woven technology, a new warp layer and / or an old warp layer warp are placed or spread on a support means, for example, a tensioner (Spanner). ) Is known to be guided up. On the surface of the tension beam, elastic or flexible (soft) radial bristles (Borsten) are attached. When this tension beam is rotated towards each end of a new warp or in the direction of unwinding (unwinding), the individual warp is drawn between the individual bristles by the tension beam and simultaneously tensioned. It will be in the state.

European Patent Application No. 0590120 (A1) U.S. Pat. No. 3,423,808 (A) German Patent Application No. 1535203 (A1)

  However, according to the prior art method, even if the tension beam with the bristles is continuously rotated, the warp yarn and in particular the aforementioned flat plastic yarn can only be stretched to a very limited extent. This is a drawback. Even if the tension beam makes one full rotation, it is completely impossible to make a flat plastic warp tension as in the case of a normal thin thread-like warp. If the flat plastic warp is dense, that is, if the flat plastic warp overlaps the tension beam several times, even if the tension beam is rotated several times, all flat It is not possible to make sure that the plastic warp is tight. The majority of flat plastic warps hang between the support means due to insufficient tension, so that the flat plastic warp of that warp layer is tied to the flat plastic warp of another warp layer This prevents reliable separation.

  In the case of performing Einziehen or Fadenkreuzeinlesen (leasing) work, it is necessary to make the warp yarns evenly stretched so that they can be separated from each other. There are similar drawbacks when flat plastic warp bristles are used.

  The object of the present invention is to solve the above-mentioned problems of the prior art.

SUMMARY OF THE INVENTION In the present invention, the subject is a clamping device having a structure in which a plurality of warps (Kettfaeden) in a frame and a warp layer (Kettfadenschicht: warp layer) are fixed locally or partially (a part thereof) to the frame (Klemmvorrichtung) and a tension device comprising a tensioner (Spanner) that is moved relative to the frame (moves the tensioner) to place a plurality of warps. A plurality of penetrating (locking) pins that can contact a plurality of warps are attached to the tensioner in the longitudinal direction or the longitudinal direction of the tensioner along the surface. The tip of the penetrating pin facing in the opposite direction (away from the surface) is inclined at an angle (ausgerichtet: oriented, aligned and adjusted) with respect to the normal direction of the tensioner surface In addition, the tip of the penetrating pin that is brought into contact with the warp is oriented in the direction opposite to (away from) the clamping device.

  The advantage of the tensioning device having the structure according to the present invention is that it has an excellent performance in which a plurality of warp yarns, in particular, flat plastic warp yarns can be surely stretched. Here, the plurality of penetrating pins attached to the surface of the tensioner along the longitudinal direction or the longitudinal direction penetrate or pierce all warps very easily and reliably. By moving or rotating the tensioner, it is possible to make all the warps more evenly stretched (warp tension) compared to the prior art by reliably piercing all the warps. This improves the separation result or performance (between warps), warp tying (Verknuepfung, knotting) or yarn joining (Fadenkreuzeinlesung, leasing: leasing, interlacing), or threading Work like (Einziehen) can be performed reliably. In order to reliably pierce the warp, as an auxiliary means, the tip of the penetrating pin facing the direction opposite to the surface of the tensioner moves in the direction of tensioning the warp with respect to the direction perpendicular to the surface of the tensioner, or Inclined or bent at a certain angle. Another advantage of orienting the tip of the penetrating pin in the direction opposite to the tensioner surface is that the warp in the tensioned state can be turned on, especially while the tension beam is turned in the direction to tension the warp. Even when the tension beam is rotated in a direction opposite to the fixing direction, the warp already pierced by the penetrating pin does not loosen from the penetrating pin and cannot be loosened or unwound. In order to tie the old (previous) warp layer and the new (later) warp layer, the tensioner can be used to tension both warp layers simultaneously. The tensioner can be formed as a flat member or element with a penetrating pin attached to its surface, and the flat member is linear, in particular longitudinal or It can be moved relative to the clamping device in the longitudinal direction, ie in the direction of the end of the warp. Further, the tensioner can be formed in a cylindrical shape, particularly as a tension beam, and a through pin can be attached to the surface of the tensioner. The tensioner can be easily rotated to keep the warp tension.

  The number of penetrating pins is selected such that each warp is pierced or penetrated by one of the penetrating pins at least once or at one location. In this case, each warp can be pierced or penetrated multiple times by two or more penetration pins. It is also possible to provide a mechanical auxiliary tool serving as an auxiliary means when the penetrating pin passes through the warp, for example, a roller having an elastic surface such as a roller made of a foam material. A force is applied to the roller so that the roller is rolled and loaded on a partial region of the surface of the warp that lies so that the penetrating pin hits the roller. As a result, the warp can be easily and reliably penetrated or pierced by the penetration pin. The force is applied substantially in the direction of the penetrating pin. After all the warps have been pierced at least once or at one location by the piercing pins, the tensioner is moved relative to the frame. Then, tension is applied to each warp, and the warp is pulled in the direction opposite to the clamping device. By fixing the warp at a position upstream of the tensioner prior to the tensioning process, the warp is evenly and reliably stretched in the partial area between that position and the tensioner. The warp beam can be fixed with a tension frame so as to fix (rotate) the warp in its rotation.

  The angle of inclination or torsion (Steigungswinkel) preferably varies depending on the site along each penetrating pin. Thereby, the warp is in a tensioned state and the engagement between the penetrating pin and the warp is improved even when the tensioning device is rotated in the reverse direction for clamping. Thereby, the warp does not come off or unravel from the penetrating pin.

  The inclination angle of the front end portion of each penetrating pin with respect to the vertical direction is preferably 90 ° to 170 °, more preferably 165 °. This inclination angle formed between the perpendicular to the surface to which the penetrating pin is attached and the tip of each penetrating pin makes it possible to form a particularly reliable engagement between the penetrating pin and the warp. It has been found that the most suitable inclination angle of the penetrating pin for penetrating the warp is 165 °. For this angle, the inclined penetrating pin automatically enters and penetrates the warp material by moving the tensioner, for example by rotating the tension beam. By adopting the penetration pin having such a structure, the warp can be completely penetrated by the penetration pin without substantially using auxiliary means. Further, the warp is prevented from coming off or unraveling from the penetrating pin.

  The tip of the penetrating pin that faces away from the surface of the tensioner preferably has a sharp or sharpened shape. Since the tip of the penetrating pin has a sharp shape, the individual warp yarns are penetrated or pierced by the penetrating pin quickly and reliably.

  When viewed from the lateral direction of the tensioner, it is preferable that a plurality of (many) through pins are arranged directly back and forth. Due to the structure in which a plurality of (many) redundant penetrating pins are arranged back and forth, each warp is always reliably penetrated or pierced by at least one of the penetrating pins. The term “lateral direction” means a direction perpendicular to the longitudinal direction or the longitudinal direction.

  In particular, when viewed from the longitudinal or longitudinal direction of the tensioner, multiple (many) rows of through-pins installed directly back and forth change their positional relationship alternately or alternately (in order) or cyclically. Or it is arranged to be shifted. In the embodiment, for example, three through pins arranged directly in front and back, that is, in the lateral direction of the tensioner constitute a row of through pins, and such a row is arranged. The through-pin rows thus configured are arranged in parallel, that is, arranged in parallel in the longitudinal direction or longitudinal direction of the tensioner while changing their positions relative to each other. With this structure, all the warp yarns are securely held or locked and pierced by a plurality (multiple) of through pins.

  The distance between adjacent penetrating pins when viewed in the longitudinal direction or longitudinal direction of the tensioner is preferably 0.5 to 1.0 mm, more preferably 0.7 mm. It has been found that when the distance between adjacent penetrating pins is in the range of 0.5 to 1.0 mm, all warps are securely grasped or locked and pierced by the penetrating pins. The interval between the penetrating pins adjacent to each other can be changed according to the width of the warp used. In that case, the interval between the penetrating pins adjacent to each other can be changed according to the width or thickness (thickness) or diameter of the warp, and as the width, thickness or diameter of the warp increases, The interval can also be increased.

  The distance between the penetrating pins adjacent to each other when viewed in the lateral direction of the tensioner is preferably 1.5 to 2.3 mm, more preferably 1.9 mm. With such a structure, the warp layer can be brought into contact with a plurality (a large number) of penetrating pins in the lateral direction without excessively enlarging the tensioner and thus the tension device.

  The tensioner is preferably formed as a columnar or cylindrical tension beam (Spannbaum) held so as to be able to rotate relative to the frame. Thereby, the warp can be put in a tension state only by rotating the tension beam.

  Further, the tension device is preferably provided with a comb portion or a comb-like member having a plurality of groove portions or concave portions, and the plurality of groove portions of the comb portions are arranged or aligned in the longitudinal direction of the tensioner, and the tensioner Can be fixed at the top of the. Here, the comb part is structured so that a plurality of (many) warps can be arranged in parallel by guiding a plurality of (many) warps through each groove of the comb part. In the structure of this form, a plurality (a large number) of warps are parallelized by passing through the grooves of the comb portion, and at the same time, are distributed and arranged so as to be uniformly distributed on the surface. Furthermore, the warp is loaded by attaching a comb on the tensioner and is therefore placed more securely (fixed) on the tensioner's penetrating pin as a whole. As a result, the warp is engaged and pierced by the penetration pin. Further, the warp is effectively prevented from coming off or unraveling from the penetrating pin.

  Furthermore, the tensioning device is preferably provided between the clamping device and the tensioner with at least one weighting device structured to exert or apply a force in the direction of the tensioner on the warp. With such a structure, the warp is weighted by gravity, for example, by a weighting device, and is pressed onto the tip of each penetrating pin. This further prevents the already pierced warp from coming off or unraveling from the penetrating pin.

  The tensioner is preferably installed between the end of each warp and the clamping device. With such a structure, the penetrating pin pierces the side of the warp that becomes waste. Thereby, the amount of waste material on the warp is reduced as much as possible.

  The tensioning device can preferably be used for bonding (knotting, knotting), preferably the two warp layers are on two planes, each plane is provided with at least one clamping device, and at least one tensioner Is preferably used. As a result, the tension device is formed so that the warps of the two warp layers are securely stretched on the two planes.

  A warp stretched in one layer can be tied or spliced to another warp stretched in another layer, or can be made with Fadenkreuz, leasing, or heald (Lamellen, healds, heddles, saddles, heels) or drop wires (eingezogen, drawn-in).

  The above-described problem is solved by a twilling machine including the tension device according to any one of claims 1 to 9.

  Moreover, the above-mentioned subject is solved by the pulling machine provided with the tension apparatus in any one of Claims 1-9.

Further, the above-described problem is further solved by a method of stretching a plurality (a large number) of warps in a tension device.
The method includes: (a) placing a plurality (many) of warp layers on at least one clamp device and a tensioner; and (b) fixing the plurality (many) warps with the clamp device. (C) a step of piercing a plurality (many) of warps with a plurality (many) of penetrating pins of the tensioner; Moving the tensioner in such a direction as to move the tensioner so that the plural (multiple) warps are stretched between the clamp device and the tensioner; and (e) fixing the warped yarn in the tensioned state. And a process.

  The tensioner is preferably formed as a tension beam. In addition, the step (d) further includes rotating the tension beam so that the plurality of (many) warps are stretched.

  In the step (c), preferably, the plural (many) warps are pressed against the penetrating pins of the tensioner, and the plural (many) warps are pierced by the plural (many) penetrating pins. To be included.

FIGS. 1 a to 1 f show a schematic procedure of a method for placing a plurality of warp yarns. . FIG. 2 is a schematic view of a warp and a penetrating pin cut in a direction perpendicular to the direction in which the warp extends. FIG. 3 is a schematic view of the penetrating pin viewed from the lateral direction of the tensioner. FIG. 4 is a schematic view showing the arrangement of through pins on the tensioner.

  Next, the present invention will be described in detail with reference to embodiments.

  FIGS. 1a to 1f show a schematic procedure for a method of tensioning or tensioning a plurality of warp yarns, in particular plastic flat warp yarns. A schematic view of a tensioning device (Spannvorrichtung: 10) comprising a frame 11 and a tensioner or tensioner 12 is shown, wherein the tensioning device 10 is in a longitudinal direction or a direction perpendicular to the longitudinal direction of the tensioner 12 ( The longitudinal direction L is represented in FIGS. 2 and 4. The longitudinal direction of the tensioner 12 is a direction substantially orthogonal to the direction in which the warp 30 is stretched. The tensioner 12 is held or attached on the frame 11. In this example, the tensioner 12 is attached to the frame 11 so as to be rotatable about an axis parallel to the longitudinal direction L relative to the frame 11. Designed and formed as a beam. On the surface of the tensioner 12, one or more engagement strips (Ineingriffnahmestreifen, engagement strip) 14 are attached. Each engagement strip 14 is provided with a number of rigid through-type retaining pins or through-pins (Durchgriffsstiften) 16. The concept of “starr” here defines the material properties of the penetrating pin, i.e. sufficient to penetrate or penetrate at least one warp. This penetration pin 16 is formed, for example with steel. The engagement strip 14 can be mounted displaceably or interchangeably across the surface of the tensioner 12.

  The tension device 10 is further provided with a clamp device including a first clamp device 18 and a second clamp device 20. The first clamp device 18 includes a first clamp rail (horizontal bar) 22 fixed on the frame 11 and a first clamp bar (bar-shaped portion) 24. On the other hand, the second clamp device 20 includes a second clamp rail 26 fixed on the frame 11 and a second clamp bar 28 (see FIG. 1f). On the surfaces of the first clamping device 18, the second clamping device 20, and the tensioner 12, a warp layer composed of a number of warps 30 is placed (see the warp layer 35 in FIG. 2). The individual warps 30 are pulled from the warp beam 31 supported on the frame 11 in the direction indicated by the arrow P to the first clamping device 18, the second clamping device 20, and the tensioner 12. Proceeding in this order, unwinding (unwinding) is performed in a direction substantially perpendicular to the longitudinal direction of the first clamping device, the second clamping device, and the tensioner.

  Further, a comb portion or a comb-like member 32 is also attached to the tensioner 12, and the comb portion is arranged in parallel with the engagement strip 14 and can be removed. The comb portion 32 is provided with a plurality of grooves or recesses, and in a stage before the comb portion 32 is fixed on the tensioner 12, a large number of warps 30 are separated substantially uniformly by passing through the groove portions. Or split. The plurality of groove portions of the comb portion 32 are separated or divided by a plurality of teeth portions or sharp ends of the comb portion not shown. The comb 32 has a function of making a large number of warps 30 parallel and pressing them in the direction of the tensioner 12.

  Next, a procedure for tensioning the warp 30 will be described with reference to FIGS. First, as shown in FIG. 1a, the warp 30 is gradually pulled out (unwinded) from the warp beam 31 by a certain length, and simultaneously onto the clamp rails 22, 26 that also function as support means, and further to the tensioner 12 It is also placed on top and set. In this case, the warp 30 is manually pulled in the direction of arrow P.

  The first clamping device 18 installed in the vicinity of the warp beam 31 is not limited to the function as a support means. It also has the function of fixing. For this purpose, the first clamp bar 24 is inserted into a groove or recess formed in the corresponding shape of the first clamp rail 22. The first clamp bar 24 inserted into the first clamp rail 22 can be locked or fixed to the first clamp rail 22 by rotating. As a result, the spread and flattened warp 30 is securely sandwiched and fixed between the first clamp rail 22 and the first clamp bar 24.

  In the case of the illustrated example, the warp 30 is pressed by the weighting device 34 in order to ensure that the warp 30 is engaged with the penetrating pin 16 (in Eingriff). The weighting device 34 is installed between the first clamping device 18 and the tensioner 12. The warp 30 that is substantially uniformly or evenly spread and flattened in this manner is engaged with the groove portion of the comb portion 32 when the comb portion 32 is inserted into the insertion portion or the recess (Aufnahme) of the tensioner 12. Bite. As a result, the large number of warps 30 are distributed and distributed so as to be substantially uniformly distributed, and pass between the respective groove portions of the comb portion 32.

  After such a preparation is made, the tensioner 12 is gradually rotated in the rotational direction R by a certain angle or distance so that the penetrating pin 16 and the warp 30 approach each other (see FIG. 1b). In the illustrated example, the rotation direction R of the tensioner 12 is the same as the rotation direction of the watch hands. In the drawing, the state of the warp 30 when the tension is manually applied to the warp in the unwinding (returning) direction is indicated by a thick solid line. On the other hand, the state of the warp 30 where no tension is applied is indicated by a broken line. When not tensioned, the warp 30 hangs at least in the portion or region between the first clamp rail 22 and the second clamp rail 26. In such a case, as described above, a large number of warp yarns 30 are separated or divided for the purpose of joining (Knuepfen: knotting) or piecing (joining), pulling or weaving. It will be impossible.

  FIG. 1 c shows the tensioner 12 in a state of being rotated in the direction of rotation R by a certain degree or a certain angle, in which case the penetrating pins 16 of the engagement strips 14 are warps 30. Direct contact with. In the example shown, the through pin 16 of the engagement strip 14 is at the 12 o'clock position of the watch. As shown in the figure, the warp yarn 30 has almost no weight so that it remains at the tip of the penetrating pin 16. When a force is manually applied to the warp 30, a large number or all of the warps 30 are pierced by the penetrating pins 16.

  FIG. 1 d is a schematic view illustrating how a warp 30 that has not yet been pierced is pierced by the penetrating pin 16. In this example, a roller 36 having an elastic surface is guided and rolled over the warp 30 and the entire penetrating pin 16 along the penetrating pin 16 or along the engaging strip 14. In this case, a force is applied to the warp 30, and this force is substantially directed toward the surface of the tensioner 12, and also acts to press or press the warp 30 against the penetrating pin 16. This force is a force large enough for the penetrating pin 16 to pierce the elastic material of the roller 36. Therefore, the penetrating pin 16 pierces the warp 30 and, in some cases, penetrates the warp 30. Only by using such simple auxiliary means, all the warp yarns 30 are securely engaged and meshed with the penetrating pin 16, and as a result, are securely engaged and meshed with the tensioner 12.

  FIG. 1e shows the tensioner 12 in a further rotated state or position in the same rotational direction R as the watch hands. In this case, the weighting device 34 is removed. Each warp 30 is pierced by at least the penetrating pin 16 and is held by the first clamping device 18, so each part of the warp 30, that is, the first clamping device 18 and the penetrating pin of the tensioner 12. The portion between the first clamp device 18 and the first clamp device 18 is pulled away by the movement of the tensioner 12 and the movement of the penetrating pin 16. Therefore, as can be seen from the drawing, the warp 30 does not hang down from the portion or region between the first clamping device 18 and the second clamping device 20. In such a state of tension, a plurality of elongated cuts or slits are formed in each warp 30, particularly each flat plastic warp, and as a result, all the warps 30 are pulled uniformly.

  FIG. 1 f shows the tensioner 12 being turned in a counterclockwise direction ZR by a small angle to reduce its tension to some extent. The advantage of aligning the direction of the penetrating pin 16 in the rotational direction of the tensioner 12 is that the warp 30 is securely engaged and meshed with the penetrating pin 16 even when the tensioner 12 is rotated in the reverse direction to reduce or reduce the tension. It is in the point that can be maintained. Therefore, it is possible to prevent the warp 30 from coming off or unraveling from the penetration pin 16.

  By uniformly applying a reduced or slight tension, the warped yarn 30 in a tensioned state can be fixed by the second clamping device 20 located away from the first clamping device 18. In order to fix the warp, the second clamp bar 28 is inserted into the groove or recess of the second clamp rail 26 which is shaped to the corresponding shape. When the second clamp bar is inserted in this manner, the warp 30 is further tensioned. The warp 30 is in a state where the portion or region between the first clamping device 18 and the second clamping device 20 is tensioned and surely and uniformly stretched, and proceeds to the subsequent separation work in that state. be able to. As another method of fixing the warp 30, there is a method of fixing the warp beam 31 so as not to rotate with respect to the frame 11. In this case, it is not necessary to provide the first clamping device 18, and in a stage before the warp 30 is in a tensioned state, the fixing device (Befestigungsvorrichtung) of the warp beam 31 is used as the first clamp for the warp 30. Functions as a device. As another method of applying tension to the warp 30 and fixing it, there is a method of fixing the tensioner 12 in the longitudinal direction or in a form that does not rotate with respect to the frame 11. In this case, it is not necessary to provide the second clamping device 20. The fixing device of the tensioner 12 functions as a clamp device for the warp 30 in a tensioned state, and the first clamp device fixes the tensioned warp 30 by fixing the tensioner 12. It functions as a fixing means away from.

  When the tensioner is formed as a flat member (element), the warp 30 is pulled out from the warp beam 31 and placed directly on the penetrating pin 16 of the tensioner 12, and the first clamping device 18 is fixed. When the warp 30 is pierced into the penetration pin 16 with (possibly) one roller 36, the tensioner moves away from the first clamping device 18 in the lateral direction of the tensioner (as in FIGS. 3 and 4). In the transverse direction Q) and in the direction of the end of the warp 30, so that the warp 30 is evenly stretched. Thereafter, the flat tensioner is moved in the original direction so that the warped yarn 30 in the tensioned state can be fixed (fixed) in the second clamping device 20. The comb portion 32 and the weighting device 34 can be used with a flat tensioner.

  The area between the second clamping device 20 and the tensioner 12 or between the first clamping device 18 and the second clamping device 20 before or during the operation of joining or splicing, twilling, pulling, etc. Thus, the warp 30 may be cut in the transverse direction perpendicular to the longitudinal alignment direction of the warps. The portions of the multiple warps 30 between this cut and their ends can be disposed of or discarded. Therefore, since the part on the so-called waste side is unnecessary, even if the penetration pin is pierced and perforated in the warp thread 30, there is no influence on the subsequent processing steps.

  FIG. 2 is a schematic cross-sectional view when the plurality of warps 30 and the plurality of penetrating pins 16 in the warp layer 35 are cut in a lateral direction orthogonal to the drawing direction of the warp 30. As can be seen from this figure, the tip of each through pin 16 is sharp. Accordingly, the penetrating pin 16 is suitable for easily penetrating or piercing the warp 30. In contrast to the prior art, according to the present invention, the warp 30 does not need to be pressed between the bristles for brushing and is pierced by the penetrating pin 16 having a sharp tip. The plurality of penetrating pins 16 are attached along the longitudinal direction L of the tensioner 12. In this case, the arrangement density of the penetrating pins is such that each warp is pierced by at least one penetrating pin. In this way, all the warps 30 of the warp layer 35 can be reliably stretched.

  In FIG. 2, the through pins 16 are aligned in a direction perpendicular to the surface of the tensioner 12, and have a shape (tapered) that is uniformly narrowed from the surface of the tensioner 12 toward the tip. The diameter of the base of the penetration pin 16, that is, the diameter at the connection point (joint) with the engagement strip 14 attached to the tensioner 12 is 0.3 mm. With the penetrating pin 16 having such a structure, even if it is a warp having a multilayer structure, the warp can be reliably penetrated and pierced.

  FIG. 3 is a detailed schematic view of the flat engagement strip 14 with a plurality of through pins 16. In this case, the penetrating pin 16 extends from the surface of the tensioner 12 (similar to the tensioner 12 of FIGS. 1 and 2) to a certain length perpendicular to the surface of the tensioner. That is, it is inclined or bent from the point where the vertically extending portion ends. In this case, the tip of the penetrating pin 16 is directed in a direction of a predetermined linear motion or rotational motion of the tensioner, that is, a direction in which the warp is pulled, with respect to a direction N perpendicular to the surface of the tensioner 12. As an advantage of this structure, the penetrating pin 16 is pierced into the warp material only by the movement of the tensioner or rotational movement, and the warp material is structurally broken at the contact point with the penetrating pin, and as a result, the penetrating pin penetrates the warp thread. To do. In the case of such a structure, it is possible to eliminate the work of applying a force to the warp in the direction of the tensioner (see FIG. 1d) with a roller or the like. Another advantage of this construction is that the warp can be reliably removed from the penetrating pin 16 as soon as the tension that creates the warp is created and then the tension is relaxed or reduced.

  The inclination angle (bending angle) of the penetrating pin 16 varies along each penetrating pin 16 depending on its part. In FIG. 3, the through pin 16 has a straight portion 16A extending linearly from the surface of the tensioner 12 in the vertical direction N, and then the straight portion 16B is inclined with respect to the normal N by an angle α or Therefore, when the penetrating pin 16 contacts the warp (see warp 30, see FIGS. 1 and 2), the tip of the penetrating pin 16 on the side opposite to the surface of the tensioner is clamped ( It faces in a direction away from the clamping device 18, see FIGS. An angle α at the end of any specific through-pin 16, that is, formed between the perpendicular direction N and a tangent at the tip 16 </ b> C of the specific through-pin 16, and facing the surface of the tensioner The angle α is 90 ° to 170 °, preferably 120 ° to 170 °, and more preferably 165 °. When the penetrating pin 16 is curved, the inclination angle always changes or gradually changes along the penetrating pin 16, that is, from the surface of the tensioner 12 to the tip portion 16C.

  FIG. 4 is a schematic view showing the arrangement of the plurality of through pins 16 on the through strip 14 on the surface of the tensioner 12. In this example, when viewed from the lateral direction Q of the tensioner 12, it can be seen that a large number of through pins 16 are arranged back and forth. In the illustrated example, two penetration pins are attached back and forth. The number of penetrating pins attached directly back and forth can be in the range of 2 to 6 within one area. Increasing the number of penetrating pins that are attached directly back and forth increases the possibility that all warps (not shown) will be gripped or ergriffen or pierced. In addition, the plurality of rows of through-pins attached so as to be directly back and forth are arranged alternately or alternately (in order) or cyclically in different positions in each row.

  In the illustrated example, four rows of through pins are arranged in parallel in the form of a plurality of through pins attached to the front and back of each row, that is, they are arranged with their positions changed or shifted from each other in the longitudinal direction L of the tensioner 12. The grouped arrangement is repeated along the longitudinal direction L of the tensioner 12. If the arrangement of the groups of through-pins 16 is changed or shifted alternately or alternately (in order) or cyclically, when the tensioner 12 moves or rotates, it always holds or engages all warps with less resources. It can be stopped and stabbed, and as a result, even if the tensioner 12 continues to move or rotate, it can be reliably tensioned. As can be seen from the figure, the cross section of the through pin 16 can be circular. As an alternative, the cross-section of the penetrating pin 16 can be rectangular (for example, made of a steel band). As a result, the possibility or probability of occurrence of a longitudinal or longitudinal cut or slit in the warp can be reduced.

  The above description of the embodiment of the present invention is merely an example, and modifications within the scope not departing from the gist (essence) of the present invention are intended to be included in the scope of the present invention. Such variations should not be construed as departing from the spirit and scope of the present invention.
