JP5255572B2 - Device and partial warping method for positioning a yarn within the width of a warp band - Google Patents

Description

  The present invention relates to an apparatus as described in the preamble of claim 1 for positioning a thread within the width of a warp band.

  In a conventional partial warper, the correct yarn arrangement and yarn density are determined by warping. In order to produce short warps or patterned warps, it is necessary to switch the yarn arrangement as quickly as possible without compromising other requirements for aging. Such a method and apparatus are already known, for example from US Pat.

European Patent No. 1524341 International Publication No. 2006/051080

  The object of the present invention is to provide a device such as the one mentioned at the beginning which allows the position of the thread to be exchanged easily and as accurately as possible in the warp band.

  This object is achieved according to the invention by an apparatus having the features of claim 1.

  A plurality of yarn guide elements are provided through which at least one yarn drawn from a yarn storage section, for example, a bobbin creel and guided to a warping drum can be inserted. The yarn guide elements are supported so as to be movable on mutually parallel movement planes or movement axes and positioned relative to each other so that the arrangement of the drawn yarns or yarn groups in the warp band can be determined by the position of the yarn guide elements. Can be done. The movement plane or movement axis of the yarn guide element is provided up and down with respect to the vertical direction. As will be apparent, the position of each thread can be determined without crossing by the movement of the thread guide element with respect to the horizontal direction or horizontal plane.

  It is advantageous that the yarn guide element is supported so that it can move linearly. As a result, the thread guide element can be controlled very accurately and a relatively small structural pattern is possible. One common bearing plane in which the yarn guiding element can be provided extends in a movement axis that intersects or is parallel to each movement plane. The bearing plane is arranged generally parallel to the warping drum and perpendicularly, or slightly inclined with respect to the normal.

  However, preferably, the yarn guide element may be supported so that it can rotate around a common rotation axis. The track of the yarn guide element may be a non-circular curve. The thread guide element can be formed, for example, by a disk, each disk having at least one thread guide passage with an inlet hole and an outlet hole on the outer peripheral surface of the disk. As can be seen, the relative position of the exit holes and the position at which the yarn exits can be changed by rotating the disk.

  The thread guide element is formed by a bar, and each bar is supported by a linear guide and has at least one guide hole or guide gap for at least one thread. Here, the term bar means any longitudinal element. That is, the term bar means a flat thin plate, for example.

  However, the yarn guide element is formed by a guide member, each guide member being supported by a guide rail and having at least one guide hole or guide gap. Thereby, it has the advantage that the substantially full length of a guide rail can be utilized for positioning, without the terminal of a rod projecting sideways with respect to a rod. The guide rail can be held within one common frame.

  The yarn guide element must of course be electrically driven and controlled very accurately. This is preferably achieved by the fact that each thread guide element is operatively coupled to each flexible transmission and can be driven in two directions of movement via this flexible transmission. The flexible body transmission device allows the drive unit to be separated from the original warp, and the flexible body can easily change direction. Furthermore, in the flexible transmission, it is only necessary to accelerate or decelerate a very light object, and therefore the output of the drive device can be kept low. However, it is naturally conceivable to drive the yarn guide element by another method such as a link mechanism or a rack and pinion. Further, for example, a magnetic drive device having a functional principle similar to that of a magnetic orbit can be considered.

  In particular, each flexible body transmission device has a Bowden wire, and at least one drive motor, preferably a stepping motor, acts on the Bowden wire. Since the motor can be kept very small, it is possible without difficulty to provide a separate drive for each yarn guide element.

  The Bowden wire is guided to the drive unit through the turning means, in which all drive motors are preferably arranged in at least one common plane or in a plurality of planes parallel to each other. Preferably it is. This allows easy access to the drive motor for maintenance work.

  A tightening device for tightening and holding a stationary thread can be attached to each thread guide element. This tightening device is necessary because not all yarns drawn from the bobbin creel are used in the warping process. Furthermore, a cutting device for cutting the yarn can be attached to each yarn guide element.

  The invention also relates to an automatic pattern partial warper having an automated multi-thread system.

  The present invention further relates to a method used by the automatic pattern partial warper for automatic warping.

  More precisely, the present invention relates to a high-power automatic pattern partial warping machine that can be used especially when preparing for weaving.

  As is generally known, the advantage of this automatic pattern partial warping machine and the reason why the automatic pattern partial warping machine has become popular in the market is the production of a small amount of warp even when the number of bobbins is limited. None (the number of yarns forming the warp (Zettel) can be arranged or wound in a defined number and can be woven as it is in subsequent processing stages), therefore weaving the pattern with multiple yarns This is due to the fact that preparation for small-scale production or sporadic small-scale production is possible.

  Commercially available automatic pattern partial warping machines can be used for more laborious weaving in some embodiments. However, in that case, the processing time becomes longer on average as compared with the conventional partial warping machine.

  The above process is currently carried out by a partial warping machine based on two working ideas.

  In the first idea, each of the yarns selected from a limited group comprising generally at least 6 yarns and at most 12 yarns is wound respectively. In such a system, the yarn is supplied from a small creel installed on the floor in front of the partial warping machine in the axial direction of the drum. Each thread is wound up in a simplified system with one or more rotating arms. In that case, the rotating arms are arranged radially concentrically around the tip of the drum, so that the yarn is turned tangentially around the roll.

  This system is subject to a series of significant limitations. Constraints include very long production times, measured in direct relation to the warp yarn and its length, and irregular winding tension on the wound surface. This is because the tension in the part descending on the roll or drum is considerably weaker than the tension in the ascending part. This is due to the fact that the yarn that is wound up as it rises is pulled more because it separates from the creel, but the reverse occurs for yarn that is wound up as it descends. The yarn and yarn length are determined via a warping program. Furthermore, the yarn is not placed directly on the winding surface, but the direction of travel of the yarn is guided around the winding surface by the system. This results in a much more serious defect when processing a series of problems with the quality of the warp and the yarn density due to the determined arrangement, for example when processing special electrostatic yarns (Garn) or smooth yarns such as viscose or silk. . In some embodiments, processing is possible only if significant compromises can be made.

Other systems known in the art are complementary to the system described above, but include a bobbin set (4-16 bobbin set) that is rotated around a roll or drum. Thereby, it becomes possible to warp a plurality of yarns simultaneously. However , there are limitations due to the small number of yarns (up to 16) and the yarns necessary for warping (the arrangement in which the various yarns must be wound) must be retained each time. This slows production in proportion to the yarn it holds.

  The system has both drawbacks.

  The first problem is that when the bobbin used in the process is empty, the work process must be stopped at all times, and since the number of the bobbins is small, the process is not completed until the warping of the warp is finished in the small volume production. Must stop at most 6 or 8 times.

  Furthermore, the yarn turning system used for the twilling process (the yarn crossing and warp texture can be pre-determined) requires considerable labor. This is because a pneumatic device and an electrical device are included, and these devices must be connected via a corresponding plug system each time during the preparation phase. Thus, during the delivery phase, i.e. when the warp must be guided onto the warp beam in order to be transferred to the weaving section, the tensile strength is limited, so it is often pulled directly (to the warp beam). The tension of the wound thread is not possible. Therefore, the process must provide an intermediate stage that doubles the delivery time. The delivery time is rather long because the output of the rewinding device is generally limited.

  In view of the above, the present applicant has realized and finished an automatic partial warping machine that can eliminate the above-mentioned drawbacks.

  Therefore, a specific object of the present invention is an automatic pattern partial warping machine equipped with an automated multi-thread system, and the automatic pattern partial warping machine includes an automatic pattern warping device. The automatic warping machine is equipped with a multi-yarn unit (double yarn thread). In this multi-yarn unit, the yarns are arranged in a horizontal arrangement irrespective of the vertical arrangement, and the yarn is moved while moving. The multi-yarn unit has two rivet units with a number of perforations, each yarn can accept one of the perforations based on the warp position, The partial warping machine includes an electronic control unit.

  In particular, according to the present invention, each of the scissors units has 32 perforations. According to the present invention, the multi-yarn unit is provided with two double fork rods and a base plate that are movable in the lateral direction, and the base plate has a slot for driving the drive string and 8 pins, of which 4 pins serve to alternately insert a set of spacers and a thin plate that form a fixed part of the heel, and the remaining 4 pins are connected to the thin plate. It is preferable that the roller separated from the spacer is held, and the thin plate and the spacer enable rotation of the outer peripheral portion of the roller.

  In particular, the roller has a double fork rod that travels on it.

  According to the present invention, each Reeds rod is moved through a string reinforced with carbon fiber irrespective of the other Reeds rods, the two ends of the string being two passages in the central part of the Reeds rod. Fixed inside.

  In particular, each end of the string is guided to the lower side of the thin plate via the turning part.

  In a more preferred solution of the invention, each string of the multi-thread unit is guided by a belt pulley, which is driven by a stepping drive and two opposing drives for the multiple belt pulleys and stepping drive. A plate is provided.

  In particular, the motors can be arranged in a V-shaped arrangement.

  According to the present invention, the partial warper for a pattern further includes a yarn holding mechanism, and each yarn is individually held by the yarn holding mechanism, and the held yarn is The lance device can be applied again to the winding roll or the warping drum.

  In particular, the yarn drawn out by the Reeds rod (which becomes a multi-yarn unit) is simultaneously hooked and guided into the groove in the yarn holding device. Therefore, the cone is carried forward in the interior by rotation to block the yarn and cut the yarn at the cutting section.

  According to the present invention, the handle partial warper includes a load device for hanging a marked thread for re-hanging on a take-up roll.

  In particular, the load device or lance device is in the vicinity of the right side of the multi-thread unit, has a curved shape, and is in contact with the take-up roll at one location, and the load device has 180 around the take-up roll. By rotating within an angle of less than 0 °, it becomes possible to hang the marked yarn on the take-up roll, and to prevent these yarns from breaking, rapid movement can be prevented by movably hanging them.

  The invention further provides means for stabilizing the yarn, in particular a multi-thread unit so that one roll pair can freely rotate around individual axes and move in a direction extending substantially perpendicular to the yarn movement direction. And the take-up roll.

  The present invention further relates to a partial warping method using the pattern partial warping machine described above.

It is a perspective view of a single guide member.

  The present invention will be described below in order to specifically show it, but without limiting to various aspects preferable for practical use. In particular, reference is made to the drawings described above.

  First, a description will be given based on FIG. 1. FIG. 1 shows a double stringer for an automatic partial warper according to the present invention. This double thread kite consists of two units, each unit being illustrated as a kite with 32 perforations (Zahnen). Within this cage, each yarn immediately arrives at one of 32 positions according to the warp arrangement.

  The double thread reel indicated by the general symbol A is composed of 32 double fork rods 2, which can move in the lateral direction, with rollers 3 provided on each. The side is guided. The frame of the flange A forms a base plate 4 having a drive string slot 5 and eight attached pins 6. A set of spacers 7 and thin plates 8 are alternately inserted into four of the pins to form a fixing portion of the flange A, and are closed by an upper plate 9. The other four pins are inserted into the thin plate 8 and the set of rollers 3 away from the spacer 7 so that the thin plate 8 and the spacer 7 can rotate the outer peripheral portion of the roller 3 itself.

  Each Reeds rod 2 is moved through the carbon fiber reinforced string 19 regardless of other Reeds rods, and the two ends of the string 19 are fixed in two passages in the central portion of the Reeds rod 2.

  Each end of the string 19 is guided to the lower side of the thin plate 8 through the turning portion 10 and passed through the slot 5 of the base plate 4.

  Since each thread passes through the central portion (guide hole 15) of each rod, each Reeds rod 2 slides one warp during movement.

  Next, referring to FIG. 2, it can be seen how each string 19 of the double stringer is guided by the belt pulley 11 moved by the stepping drive device 12. The two drive plates 13 that can be identified are attached to face each other, and the entire mechanism is provided between the drive plates 13.

  Each drive plate 13 includes 16 motors (eight on each side) arranged in a V shape, and the direction change is performed by a set of disks 14. This arrangement was chosen because it optimizes the dimensions of the assembly.

  The motor 12 is controlled by an intelligent drive, which is interconnected with a PC-based control unit.

  In the original warping stage (see FIG. 3), the yarns are arranged in steps according to a process determined by the number of warps per centimeter and in the order required for the pattern. When the warp yarns are combined and all the yarns are used, the double yarn kite A has the configuration shown in FIG. Based on the dimensions of 筬 A, the maximum settable process can be determined, and the minimum warping process depends on the resolution of the mechanical drive system.

  Referring now to FIG. 4, it can be seen how during the warping process the yarns are arranged and what auxiliary devices can complete the process. Reference numerals 21 and 22 indicate yarns arranged in a vertical arrangement. The yarns remain separated from each other in the vertical direction and can therefore be transferred individually to a horizontal arrangement without crossing. Another advantage is that, unlike conventional warping systems (with warps), basically 2 to 14 yarns are introduced at each perforation of the scissors. Usually, the number of yarns is 4-8. Therefore, in the case of a twisting or twisting problem, the yarns can cross in a spiral and cause problems during the subsequent weaving process.

  The yarn runs completely freely from heel A to the winding point, which may cause problems during the warping process. These problems are due to the static nature of the yarn, or the mechanical action of the wind generated by the rotation of the warping drum or the yarn itself. In certain embodiments, these problems may or may result in warp quality degradation.

  By the way, this problem always appears on various scales in so-called “monofilament” machines. The solution when using this is that the system is equipped with a device as schematically shown in FIG.

  Both rollers 24, 25 rotate freely about separate axes. These rollers are normally closed as shown in FIG. However, before and during the entire weaving process, the rollers 24, 25 are opened and the roller 25 moves in the direction 26 and the roller 24 moves in the direction 27.

  The running direction of the yarn is indicated by an arrow 28. As can be seen from the position indicated by reference numeral 29 on the winding surface of the warp yarn, the yarn is newly arranged in the horizontal direction, which has already occurred in the partial aging. This ensures high process quality with ideal method technology.

  Thus, apart from the warping drum and cone size constraints, there is no constraint in warping with respect to the number of meters to be wound. Therefore, the partial warping machine can be widely used for automatic warping in an enlarged range.

  FIG. 6 shows the functional principle of the yarn holding device. The yarn drawn out by the Leeds rod 2 (double yarn rod A) at the position indicated by reference numeral 30 (the position where the yarn is excluded from warping) is simultaneously hooked on the rod 31 and guided into the groove 32. A device 33 rotating in direction 34 carries the cone forward to block the yarn and cuts the yarn at the cutting section 35. This device 33 can be implemented in various ways while maintaining the same functionality. With this process, the yarn is held until it is marked for re-hanging. For this process, the Lees rod 2 of the double thread kite A is moved to the hanging position. In this position, a lance called “loading device” contains all the yarns and synchronizes with the subsequent roll (technically called “floating cut”) to hang the yarn on the roll. be able to.

  The load device is in the vicinity of the right side of the double yarn thread A. The load device has a curved shape, contacts the winding roll at one place, and rotates around the winding roll in an angular range of 180 ° or less. This makes it possible to hang the marked yarns on the warping drum and avoid the rush by floating them for the obvious purpose of preventing them from breaking.

  The Lees rod 2 of the double yarn thread A has substantially three working positions or working areas, that is, a) warping / twisting area, b) yarn holding area, and c) yarn hooking area.

  During the warping process, the yarn needs to move continuously between a position where the yarn is guided into the partial warper (a creel position where the yarn is fed from the bobbin) and the position of the warping drum 40. The warping drum 40 (see FIG. 7) includes a conical portion 42 on which the yarn of the first warp band is placed, and a cylindrical portion 41 where all the subsequent warp bands are gradually gathered by the movement.

  This type of movement can be accomplished by moving the entire partial warp machine relative to the creel according to conventional methods. You may make it shift the cone 42 which has all the warp bands previously arrange | positioned on the warping drum 40. FIG.

  In the first embodiment, the warping drum 40 is composed of one unit. On the other hand, in the second embodiment, as shown in FIG. 7, the warping drum 40 is completely cylindrical, and the conical body 42 is a ball bush guide and is an independent unit that moves on it.

  The warping drum 40 has a raised portion, and a belt 43 is disposed on the raised portion. Therefore, the yarn is wound on the belt 43 instead of being directly wound on the cylindrical portion 41. In that case, these belts 43 are connected to a conical portion 42, which moves the belt 43 by its own movement and moves the warp.

  In the first embodiment, the automatic weaving process is performed with a movable weaving rod called a Leeds rod (a process known under the “Versomat®”). The movable weaving rod is gradually shifted in the direction of the cylindrical portion 41 of the machine together with the warp arrangement on the warping drum 40.

  In another embodiment, sixteen high weaving bars 44 and low weaving bars 45 are arranged on the warping drum 40. Unlike the conventional machine, these twill rods 44 and 45 are fixedly attached. The conical portion 42 has slots and the position of the high weaving rod 44 can be adjusted within these slots. Since the movement of the warp causes relative movement between the weaving bars 44 and 45 and the warp, the weaving bar is fixedly attached.

  When the cylindrical portion 41 has no warp, disks 46 are mounted along the rolls to prevent excessive vibrations of the weaving rods 44, 45 and the belt 43, and these disks 46 have circulation balls. It is coupled to the guide via a linear guide and is moved on the smooth surface of the belt 43 by the belt 43 itself via the vulcanized protrusion.

  The double yarn thread A according to the present invention can be combined with the modification of the warp drum type accessories of both of the above-described embodiments, and the treading process is carried out with one of them and on the warping plane. As long as the even-numbered yarn can be moved from the odd-numbered yarn (and vice versa), the function of the twilling can be provided.

  As can be seen from FIG. 8, in this case, the Reeds rod is pulled out relative to the other devices because of the lower collecting plate 47 and the upper collecting plate 48. As can be seen from this figure, the even-numbered yarn is diverted outwardly from the previously drawn lead rod.

  Therefore, the shape of the groove 49 and the geometric shape of the weaving bar enable a natural continuous sliding on the lower side of the weaving bar, thus completing the weaving process. The process goes through on the upper side as well. However, in that case, it depends on the geometric shape of the twill rod 50. In that case, the double yarn fold A behaves as a conventional warp. This is because the yarn slides in the B direction only by the advance step defined in advance by spiral movement, and the distance from the winding position of the yarn is kept the same.

  In FIG. 8, a thread selector is further shown, which is indicated by the reference numeral 51 in its entirety.

  Next, considering FIG. 9, there is illustrated a warping drum section for an automatic partial warping machine with a section of the warping drum 40, a fixedly mounted weir rod and a movable cone. Yes. In this case, the system operates in much the same way as the system described with reference to FIG. The difference is that the Reeds rod is not pulled out. Rather, the warp is driven by the belt 43 and moves in the direction of arrow C. In that case, the conical body 42 is a part firmly coupled to a belt 43 that is generally used in a partial warping machine having a monofilament pattern. The presence of the cone 42 is again a new point introduced in the present invention. The cone 42 moves rearward and thus becomes an important mounting element for constructing the warp.

  In both the system of FIG. 8 and the system of FIG. 9, the double yarn thread A returns to the cylindrical part 41 downward at the starting point at the end of winding and warps with the yarn per cm in the opposite direction of the arrow B. It moves to the extent that it matches the ratio with the number of yarns. However, in both embodiments, unlike what has been done with this type of partial warp to date, the warp conical mounting surface results in a nearly ideal configuration of the warp.

  The innovative technical solution provided by the present invention consists of a multi-yarn unit A, also called double yarn fold. The multi-yarn unit A can warp a plurality of yarns, and can determine a yarn arrangement and a situation or degree of arranging the yarns mutually.

  The horizontal arrangement when arranging the yarns prevents the yarns from overlapping each other during movement, so that the “double yarn folds” A can be prevented from being influenced by the vertical arrangements therein.

  This allows the yarns to be placed in a predetermined arrangement. However, the yarns can also arrive at variable positions in relation to each other (for example, when different counts or types of yarn are warped). This step can be carried out without stopping the winding roll or the warping drum 40 motor.

  The system further includes a yarn holding mechanism that can hold each yarn individually.

  The retained yarn can be re-hanged on the warping drum when a new winding is started. This is done by means of a lance on which the yarn is placed, and the double thread fold A is moved between a yarn cutting position and a warp position. The yarn thus hung on the “loading device” is marked at this point for re-hanging on the warping drum 40.

  This achieves a number of advantages over the prior art. In particular, because of the handle, it is possible to newly hang a thread that had to be held in advance. Or, the bobbin is almost empty, so it can even hang a thread that is rebound. This allows warping to be started again, and production interruptions are reduced to a minimum (only when the yarn is tied).

  The electronic system manages the entire logic, steps the twilling process, and reverses the twilling process when the yarn wound at a given time is an odd number of yarns.

  Even though the system can be adapted to a partial warper having a discontinuous warp band, this is a continuous warp. The entire warp is thus warped and subsequently a plurality of yarns in the double thread fold A are added. The program determines each point at which a new winding starts at the beginning of the roll. This applies to the entire warp.

  Numerous advantages are achieved by the solution brought by the present invention, and warping can be carried out in a supervised pattern (this solution is today only using a partial warping machine for the pattern, (Achievable with a limited number of [16] yarns). If the number of bobbins indispensable for warp is limited, the warping can be continued without being affected by such a limitation. This process is possible with a relatively large number of yarns because they are interchangeable.

  With the partial warping machine according to the present invention, an unlimited number of patterns can be realized. This is because the type of pattern is limited only by the number of combinations that can be achieved by thread interchange. Furthermore, the pattern can be changed in near real time at the beginning of each winding.

  Another advantage achieved with the partial warper according to the invention arises from the fact that the yarns are held separately until delivered to the winding position. In a conventional partial warper having a ridge, a minimum of 2 to a maximum of 10 yarns are grouped in one perforation. Therefore, twists can occur and these twists can cause overlap during the winding phase.

  The automatic weaving process according to the invention can be carried out very simply. This is because, with double thread control, the thread can be separated into two groups without problems, that is, the thread that must run on the weaving rod and the thread that must run below it. It is.

  For purposes of illustration, but without limitation to the preferred embodiment for practical application, the invention will be described. However, it will be apparent to those skilled in the art that changes and / or modifications can be made without departing from the scope of protection as set forth in the appended claims.

  FIG. 10 schematically shows a partial warping machine 39 with a warping drum 40 having a cylindrical part 41 and a conical part 42. As already mentioned in connection with FIG. 7, the surface of the cylindrical portion 41 is formed by the movable belt 43. The conical portion 42 is movable together with the belt 43 in the direction of the rotation axis of the warping drum. The warping drum 40 is supported in a machine base 55. The machine base 55 also accommodates the remaining components such as a drive motor, a braking device, and a control device. The principle of the movable conical part connected to the belt 43 could also be used in a conventional partial warping machine with a conventional warping module, under certain preconditions.

In the machine base 55, a warp carriage group 56 is arranged on a warp carriage guide arranged parallel to the inclination of the cone. The warping carriage group 56 is shown in some detail in FIG. 11. The original warping carriage 63 includes various units of the warping carriage group 56, that is, a yarn guide unit 57, a drive unit 58, and a yarn block. A unit 59 is arranged. A treading rod 60 is arranged in the holder behind the yarn guide unit 57 as viewed in the yarn traveling direction, and the roller pairs 24 and 25 already described in relation to FIG. 5 are arranged behind the holder. The individual rollers 24, 25 can be moved toward or away from each other in the guide rail 62.

  The drive unit 58 is configured in the same manner as in FIG. Therefore, it will not be described in detail again here. On the other hand, the yarn guide unit 57 has a slightly different functional principle from the double yarn thread A shown in FIG.

  Other details are apparent from FIGS. 12 and 13. The yarn guide unit 57 includes a cylindrical housing 64, and the cylindrical housing 64 has two housing holes 65 that are opposed to each other in diameter in the yarn traveling direction. A total of 64 disks 68 are stacked and supported in the housing 64, and the disks 68 function as thread guide elements. The discs 68 are individually rotatable around a common shaft 66 supported in the shaft box 67. Each disk 68 can be rotationally driven by a Bowden wire 73 acting on the outer peripheral surface 72 of the disk. Each Bowden wire 73 communicates with the drive unit 58 already described through direction changing means not shown in detail here.

  In particular, as is apparent from FIG. 13, each disk 68 includes two guide passages 69a and 69b each having an inlet hole 70a and 70b and one outlet hole 71a and 71b. A thread 1a or 1b can be inserted into each guide passage 69a, 69b. A compressed air passage 74 is provided as an insertion aid, and compressed air can be fed from the central shaft to the outlet hole via the compressed air passage 74. Thus, the yarn is pulled in by the pressure difference generated between the inlet holes 70a and 70b and the outlet holes 71a and 71b.

  As will be apparent, the position of the yarns that come out changes as the relative angular position of each disk 68 is turned.

  FIG. 14 further shows details of a yarn block unit 59 for blocking yarn that was not used in the warping process. In the perforated plate 75, two hole rows 76 are arranged in the vertical direction, and the hole rows 76 are coupled to the corresponding passages. Each passage can be closed with a pneumatic microcylinder 77 so that the thread is clamped in the passage. Compressed air is supplied to the micro cylinder 77 via an air pressure control device 78.

  FIG. 15 schematically shows another embodiment of the yarn guide unit. The yarn guide element comprises individual guide members 79 supported in a frame 84 so as to be linearly movable. Each guide member 79 accommodates at least one yarn 1 and guides the yarn to a desired position with respect to the warping band 20 formed by the roller pairs 24 and 25. Each guide member 79 is coupled to a Bowden wire 73 on both sides, and the Bowden wire 73 is guided to a drive unit via direction changing means not shown in detail here.

  The basic principle is clear from FIGS. Each Bowden wire 73 moves the guide member 79 and preferably moves within the guide rail 80. However, in certain embodiments, it may be envisaged to hold the guide member 79 free of tension without additional guidance by the Bowden wire 73. In order to apply a predetermined tension to the Bowden wire 73, at least one pretension spring 81 is integrated with the Bowden wire 73. Each Bowden wire 73 is wound around a pulley 82 connected to a stepping motor 83. Due to the winding friction at the pulley 82, the Bowden wire 73, ie the guide member 79, can move in both directions of movement. At this time, as is apparent, the guide member 79 does not necessarily need to be linearly moved. The guide member 79 could be guided in a curved guide rail, for example.

  In FIG. 18, one guide member 79 is shown in more detail. The guide rail 80 is formed as a flat bar, and the guide member 79 slides on the bar like a slide shoe. There is a guide hole 15 in a plane below the guide rail 80, and the yarn 1 can be guided without contacting the guide rail 80. The guide member 79 can be made of, for example, a plastic material.
