Description of the invention: [Technical field of invention] 3 The present invention is a warp knitting machine having at least one jacquard bar and a plurality of guide pins driven by a driving device It can reciprocate in a 5 traverse direction with a traction member between the guide and the drive. t Prior Art] The above-mentioned warp knitting machine is disclosed in German Patent No. DE 101 37 601 A1. The guide pins are suspended from the wire or wire and connected to the tensioning elements on the ends of the wires or wires 10 so that the ends of the wire are subjected to the same force. The drive motor with the elastic band wound around the drive gear is as long as it has the power required for the guide pin, without the power required to tension the spring or other tensioning device. In this case, the device is pulled down into cylinders which hold the tension by compressed air. 15 Such machines may occur, for example, during assembly or even during operation, where compressed air supply is interrupted. When the manufacturer transports the machine to the customer, the machine supplies only compressed air. In this case, the traction member may not be able to stand in position due to lack of lateral rigidity, and there is a risk that the traction member will fall from its position and become entangled. Rebooting the machine requires a huge amount of money. Before the heavy 20 new start, the traction members must be separated and returned to their original positions. When replacing the jacquard bar, for example, by additionally dispensing the guide pin, the traction member may become entangled and damaged. SUMMARY OF THE INVENTION The present invention is a warp knitting machine, the warp knitting machine 1279465 has a parent comb, a plurality of guide pins, which are driven by a driving device to move in a reciprocating manner, wherein There is a traction member between the guide pin and the drive unit.

置。而只需將制動裝置分組聯合在一起，並且一台制動裝 置配屬多支牵引件。這樣既節省裝製空間叉簡化操控運 作。因此對所有牽引件，制動裝置必須永遠同時運作，至 少一組牽引件與一台制動裝置同時運作。 5 最好一組牽引件疊放在一起，當在制動裝置工作範圍 内之牽引件做成皮帶狀時，尤其相當有利。在這種情形， 可將多支皮帶壓在一起。如有足夠的力量進行這個動作， 根本不需要過大之力，皮帶便能確切地固定在其位置上。 在制動裝置範圍内安裝一台導向裝置，這部導向裝置 10 在與制動裝置橫移方向平行之方向運作。假如制動裝置做 成夾緊裝置，導向裝置則確保皮帶在壓在一起時不會偏移 到一逆去。制動裝置與導向裝置在一超時，起動制動程序 仍能確保皮帶持編在其位置上。 制動裝置同時運作多組牽引件，各組應同樣高。例如 15 可以將兩組或三組牽引件安置在鄰接位置，這樣可以使這 些牽引件組由同一部制動裝置進氣衝擊，如此一來，還可 以節省空間。試想，一台經編針織機具有大量的牽引件， 例如64支牽引件以及對應組數之導針，那麼四部制動裝置 便足夠使用’假如將每八支牽引件相互重豐成一組’而且 20 兩個這樣的組並排放在一起。如此一來這兩個組的上6支牽 引件便可由一台制動裝置進氣衝擊。 將制動裝置預先在拉緊方向繃緊，而且制動裝置應具 備一台拉緊驅動裝置。在如此安排下，當一個辅助能源， 例如壓縮空氣或電力，消失或減少到輔助能源自身再也無 1279465 2減制動力時，㈣裝置便會自動起動。因 曰、胃不必為了干擾’而採取其他措施。辅助能源一 —靖失，牽弓丨件便被固定住。 5 =種情況下，制妙置最好具備—支壓縮彈菁，麼 ^育疋-個結構簡單的組成部件。在運轉時，也就是在 ^有干擾情況時，簧被卿，例如藉缓縮空氣或 j由磁力。當獅能源消失時，對應之壓、轉簧無法再被 日守，牵引件便會被制動裝置固定下來。 10 在取好的安排，制動裝置具備一個可運動的頭部，這 10個碩部與—個石占共同起作用。例如頭部可以藉由上述的壓 ，彈簧運動，其它驅動裝置也同樣可以做到這點。假如頭 邙朝砧移動，那麼便會把位於頭部與砧之間的牽引件 並固定。 在這種情況下，頭部具備一個可變形的額面，可變形 15的額面配合多支牽引件或一支牵引件的外型，並且固定住 夕支或一支牽引件。可變形的額面也能夠平衡鄰近組之間 的車父小高度差距，如此一來便可用一部制動裝置將多個牽 引件組固定住。 最好頭部由聚合物製成，聚合物塑料的好處是成本低 20廉。亦可以將頭部視為不時要更換的磨損部件。聚合物， 也就是聚合物塑料，更具有足夠彈性，能在進氣衝擊牽引 件時承受表面差異。 在一特別好的具能貲施例中，站向頭部移動。在這種 情況下，不僅頭部運動，而且站亦移動。如此一來，便可 1279465 作到牵引件藉頭部與石占之間的失緊作用不致嚴重偏移，牵 引件的載荷也會因此得以控制。 在這種情況’可將制動器作為石占的路徑邊界，如此一 來’石占只能在預設的位置上移動。這個位置的挑選必須顧 5到使牽引件有-個理想的活動路捏，在短牽引件方面，特 別能將偏移控制在界限之内。 该石占有-驅動裝置，其功能此頭部的驅動裝置的功能 強。如此，頭部則可移開驅動裝置，例如有一壓縮彈簧， 石占在兩部相同之驅動裝置進汽衝擊時，則有對應之總共兩 10支壓縮彈等。砧只能在預設住置之前運動，該位置之選擇 以牽引件之歷程最佳化為準。可以藉此實現此點的作法， 例如，移動配有壓縮彈等的驅動裝置的頭部，對兩部配有 相同驅動裝置的砧進氣衝擊。該兩部配有相同驅動裝置， 對應全部兩支壓縮彈簧。如此一來便能確保砧的位置只能 15由制動器固定，頭部之力不能有任何改變。 牵引件最好只在驅動裝置之一邊，在這件事上，在另 連由轉向輥將之導向一個具有周向槽的拉緊裝置，這個 槽至少用一個固定的制動裝置蓋住重力方向的下尾端。牵 引件不再端緊於兩個拉緊裝置之間，而只是一端固定在驅 20動裝置上，另—端固定在拉緊裝置上。當拉緊裝置失去拉 力時，驅動裝置範圍内的牵引件便會由制動裝置固定住， 在相對的另一端則不需制動，因為那裡的牵引件固定在轉 向報上。這個夹具在結構上很簡單，在這個尾端可做成， 比如說，吊在鋼絲上的牵引件，在這裡只是被固定在轉向 1279465 輥的一個周向槽裡，無法出來。 在這種情況下，最好將多個轉向輥安置在一起，其中 相鄰轉向輥之間的隙缝，比隙縫範圖内牵引件的最小截面 的尺寸還小。在這種情況下，牽引件不會單方脫離轉向輥， 5 因為在這個範園内轉向親的周向槽被相鄰的轉向輥所遮 蓋。只有在最外層的轉向輥需要另一種方式的遮蓋。 接下來將藉由幾個最佳具體實施例，配合圖式進一步 說明本發明如次： 第1圖：一具有一支牵引件的經編針織機示意圖， 10 第2圖：一具有多支牽引件的經編針織機示意圖， 第3圖：兩部制動裝置的透視圖 第4圖：牽引件尾端的轉向輥放大圖 第5圖：第4圖的V-V剖面 第6圖：第4圖的VI-VI剖面 15 第1圖示一經編針織機的截面，該經編針織機具有一支 提花梳櫛、及一支導針2。經編針織機，在一般情況下，具 有多支提花梳櫛，而每一支提花梳櫛1，在一般情況下，具 有一支以上的導針2。不過第一圖中的經編針織機只供作簡 化說明用。 20 導針2固定在鋼絲3上。當鋼絲3往復運動時，導針2亦 在橫移方向往復運動。橫移方向與鋼絲3的縱向延伸平行。 在一端(在第1圖中右方)鋼絲3經由轉向報4被導向拉緊裝置 5，拉緊裝置5對鋼絲3產生一不受距離長度影響的拉力作 用。為達成此目的，拉緊裝置5可以，例如，做成壓縮空氣 10 1279465 汽缸之形式。 在另一端，鋼絲3藉一可鬆開的聯結器7與鬆緊帶6連 接。鬆緊帶6則環繞在鼓輪8上，鼓輪8被固定在傳動機構10 的起動軸9上。在傳動機構10之入口側安裝一台馬達11，該 5 馬達11為電動馬達，最好是伺服馬達、永久磁化同步馬達 或步進馬達。原則上，可以小角增量操控的馬達，都可以 作為馬達11。用於操控馬達11的電子控制設備，圖中並未 示出。馬達、傳動機構與鼓輪8共同構成驅動裝置21。 鋼絲3與鬆緊帶6共同組成牽引件12,牵引件12在運轉 10 時，由拉緊裝置5拉緊固定。馬達11的運作只對拉緊裝置5 起作用，如此，始能起動傳動機構10，即使傳動機構10有 遊隙。這個遊隙不受牽引件12的運動方向之影響，在同一 方向縮小。 在運轉過程和起動過程一樣，都無法避免干擾。例如， 15 壓縮空氣供應中斷，牽引件12的張力便會消失，如此會造 成牽引件12脫離其界定之位置的危險。 為了排除這種情況，乃有制動裝置13之設置，在遭遇 干擾時，即起動。制動裝置13具有一砧14，砧14與頭部15 共同起作用。頭部15係由聚合物材料製成。在某種範圍内 20 會軟化。有一部導向裝置16固定在砧14上，例如，帶有尖 齒17、18的叉子，這兩個尖齒與頭部15的運動方向平行伸 展。 頭部15由驅動汽缸20用衝桿19驅動，在驅動汽缸20上 安裝一個壓縮彈簧（圖中未詳示）。在無反力作用下，這個壓 11 1279465 縮彈簧會把頭部15向站14方向擠。不過衝桿19在辅助能源 (例如壓縮空氣)運轉時，會離開砧14，如此一來頭部15與砧 14間保有足夠的距離，而鬆緊帶6也可在石占14對面自由運 動。壓縮空氣供應中斷，不僅拉緊裝置5的效應會減低，而 5 且安置在驅動汽缸20中的壓縮彈簧亦無法再保持緊縮狀 態’而會用頭部15朝站14方向往前推衝桿19，並在鬆緊帶6 的中繼位置下方將頭部15固定在砧14上。導向裝置16藉此 防止鬆緊帶6向一側移位。 驅動汽缸當然也可以有其他的構形。例如可在砧14與 10頭部15之間裝一磁性聯結器，頭部15則因磁力而被砧14吸 引。在這種情況下’也可在驅動汽缸2〇中安排一個由壓縮 空氣產生的阻力，這個阻力也可以其他方式形成，例如， 樣藉由磁力。驅動汽缸2〇亦可做成電動線性馬達，這部 電動線性馬達能夠克服由彈簧形成的阻力，以便能在運轉 15無干擾狀況下，頭部15與砧14保持足夠距離。不過只要出 干擾而拉緊衣置5無法繼續發揮其功能時，制動裝置工3 ^啟動，而頭部15會將鬆緊帶6夾在其與賴之間。如此 來便可防止牽引件12離開其位置，因而與（圖中未詳示) 的牵引件12纏繞在一起。 20 I圖不在使用多支牽引件時，在沒有干擾狀況下運作 擾狀況下運作的對照情形。與第1圖中相同的部件 Μ同樣的符號表示。 母支牽引件12都在—端裝配專屬的拉緊裝置5,而在另 則是裝配專屬的驅動裝置，在這個驅動裝置上有鼓輪 12 1279465 動衣置13在第2a圖中並不在運作狀態。頭部15與砧14 之間有足夠的間距，如此一來，在牽引件12 一端的驅動裝 、及在牽引件12另一端之拉緊裝置5的作用下，導針2 便忐在橫移方向往復運動。 5 旦由拉緊裝置5產生的拉力消失，便可能產生各個牽 引件12相互纏繞在一起的危險，例如，從其規定的位置掉 出來。透過制動裝置13可以防止這種情形發生，如第沘圖 所不，為制動裝置13在起動位置的狀態。頭部15移向砧14， 所以將牽引件12，更準確地說是將牵引件12的帶狀部分6， 10夾在碩部15與砧14之間。這時導向裝置16防止牵引件12向 一側移位’因此制動裝置13同時作用於多支牽引件，在詳 細說明的具體實施例中有六支牽引件。如此一來，牵引件 12不僅被固定在經編針織機對面，而且彼此相對位置亦固 定’因此牽引件12就不會相互纏繞在一起。 15 第3圖示一具有兩部制動裝置的具體實施例，該制動裝 置對應第1圖及第2圖實施例中之制動裝置13。頭部15可以 向固定的砧14移動，位於砧14與頭部15間之牽引件在此並 未示出。 制動装置13的驅動汽缸20固定在相同的支架22上，尚 20安裝另一制動裝置23。制動裝置23具有一砧24，而頭部25 與砧24共同起作用，頭部25由驅動汽缸2〇a推動。驅動汽缸 20a與制動裝置13的軀動汽缸20完全相同。 石占24在兩個驅動汽缸2〇b、20c上方，朝向頭部25的方 向移動。驅動汽缸20a、20b、20c與制動裝置13的驅動汽缸 13 1279465 20係以相同方式製作者，不過雜僅可到達制動 器26，制 動器26相對形成距雜長度限制。制動器％固定在支架^上。 假如現在壓縮空氣供應中斷，那麼所有的驅動汽缸 20、20a、20b、20c都會起動。石占24會經由驅動汽缸獅、 . 5 20c到達制動器26 ’也就是與頭部25會面。同時頭部25會期 砧24的方向行進，以致砧24與頭部25之間的牵引件12會被 夾住。藉由兩個驅動汽缸2〇b、20c作用於砧24，作用於砧 24的動力比作用於頭部25的動力還大。因此砧以到達制動 器26的裝置，即使頭部25將牽引件12固定在砧以上面，仍 擊 1〇 停留在那裡。 在第3圖中可看到頭部25將兩組牽引件進氣衝擊，此時 每組牽引件12都具備多條上下疊放的帶子。兩組高度相 同，如此一來所有的牽引件12都能牢固地被固定住。較微 小的差錯或公差都能經由頭部25的彈性及軟性予以補償。 15 站24的運動性有妤處，即牽引件12不必(例如在第2b圖 中所示)被大力拉偏離，尤其是短的牵引件12會因此而減低 何載。 第4至6圖，僅示牽引件另一端的情況。 牵引件12被導向通過轉向輥4。正如第5圖中所示，每 20 個轉向輥4都由支架27支承，並具備一個周向槽28、在周向 槽28中有牽引件12，支架27上有固定之銷釘29，而且是在 重力方向最深的位置。銷釘29遮盖周向槽28 ’因此牽引件 12就不會從周向槽28中滑落。銷釘29 ’此外與轉向輥4沒有 任何接觸，如此一來也就不會產生額外的磨擦力。 14 1279465 5 10 15 20 假如拉緊裝置5的張力消失，雖然牵引件可以在重力作 用下稍微向下滑，不過牽引件還是無法離開轉向輥4上的周 向槽28，因為銷釘29防止牵引件位移。 另一項措施可從第6圖中看出，相鄰的轉向輥4具有間 距a，這比牽引件12在這個範圍内的最小截面尺寸還小。如 此一來相鄰的轉向輥4便將牵引件12固定在相鄰的轉向輥 之間。 只是最外圍的轉向輓4 a缺乏一個用於固定牽引件的相 鄰轉向輥，在此可以安裝一個銷釘30，銷釘30利用與銷釘 29相似的方式將周向槽28遮蓋。 從這些具體實施例中會有各種各樣的偏差，制動裝置 上3、23會比上述兩組牵引件抓得更牢，可使砧14、24具有 彈性，而使頭部15、25的柔韌性差些或軟些，如此一來有 關砧14、24的不準確性才可以接受。另外也可能只讓砧24 運動，而將頭部25固定住。 除了用壓縮空氣作為辅助能源之外，也可用電力作為 輔助能源，以使頭部15、25與砧14、24之間的空隙持續敞 開。當輔助能源中斷時，無論如何要起動制動裝置13、23。 L圖式簡單說明3

This is - (four) braking device __ heart:: hope =. The resulting frictional force is made with a belt in the range of the traction members. When the skin is a clamping device, the upper ramie is flat. In particular, it is easier to make the brakes on both sides of the belt. The operator only needs to use - stop the friction • to have the guards and this effect must be sufficient to best serve more. No (four) f + Μ follow-up 4 simultaneous pair-level traction parts Ten female support bows each set - Taiwan-specific brakes 1279465 set. Instead, the brakes are grouped together and one brake is equipped with multiple tractors. This saves the installation space and simplifies handling. Therefore, for all traction members, the brakes must be operated at the same time forever, and at least one of the traction members operates simultaneously with one brake device. 5 Preferably, a set of traction members are stacked together, which is particularly advantageous when the traction members are in the form of belts within the working range of the brake device. In this case, multiple belts can be pressed together. If there is enough power to do this, there is no need for too much force, and the belt can be fixed in its position. A guide is mounted within the range of the brake device, and this guide 10 operates in a direction parallel to the traverse direction of the brake device. If the brakes are used as clamping devices, the guides ensure that the belts do not shift back when pressed together. When the brakes and the guides are overtime, the start of the brake program still ensures that the belt is held in its position. The brake device operates multiple sets of traction members at the same time, and each group should be equally high. For example, 15 or two sets of traction members can be placed in abutting positions, so that the traction members can be impacted by the same brake device, thus saving space. Imagine that a warp knitting machine has a large number of traction members, such as 64 traction members and a corresponding number of guide pins, then the four brake devices are sufficient to use 'if every eight traction members are made into one another' and 20 Two such groups are discharged together. In this way, the upper six traction members of the two groups can be impacted by a brake device. The brake device is pretensioned in the tensioning direction and the brake device is provided with a tensioning drive. Under this arrangement, when an auxiliary energy source, such as compressed air or electricity, disappears or is reduced to the auxiliary energy source itself, no more braking force is reduced. (4) The device will automatically start. Because the stomach and stomach do not have to take other measures to interfere. Auxiliary energy - the loss of the hinge, the bow member will be fixed. 5 = In the case of the case, it is best to have a combination of compression and compression, and a simple structure. In operation, that is, when there is interference, the spring is stunned, for example, by slowing down air or j by magnetic force. When the lion energy disappears, the corresponding pressure and spring can no longer be kept, and the traction parts will be fixed by the brake device. 10 In the arrangement, the brake device has a movable head, and the 10 masters work together with a stone. For example, the head can be moved by the above-mentioned pressure and spring, and other driving devices can also do this. If the head squats toward the anvil, the traction member between the head and the anvil is fixed. In this case, the head has a deformable frontal surface, the front surface of the deformable 15 is matched with the shape of a plurality of traction members or a traction member, and the yoke or a traction member is fixed. The deformable frontal surface also balances the small height difference between the adjacent groups, so that a plurality of traction members can be held by a brake device. Preferably, the head is made of a polymer, and the benefit of polymer plastic is a low cost. The head can also be considered as a worn part that is replaced from time to time. Polymers, also known as polymer plastics, are more flexible enough to withstand surface variations when the air intake impacts the traction member. In a particularly good embodiment, the station moves toward the head. In this case, not only the head movement but also the station moves. In this way, the tension between the head and the stone can not be severely offset by the 1279465, and the load of the traction member can be controlled. In this case, the brake can be used as the path boundary of the stone, so that the stone can only move in the preset position. The selection of this position must take into account that the traction member has an ideal movable path pinch, and in the case of short traction members, the offset can be controlled within the limits. The stone occupies a drive device which functions as a drive for the head. In this way, the head can be removed from the driving device, for example, there is a compression spring. When the stone occupies two steam inlets of the same driving device, there are correspondingly a total of two 10 compression bombs. The anvil can only be moved before the preset is placed. The choice of this position is based on the optimization of the traction course. This can be achieved by, for example, moving the head of a driving device equipped with a compression bomb or the like to impact the two anvil inlets equipped with the same driving device. The two parts are equipped with the same drive unit, corresponding to all two compression springs. In this way, it can be ensured that the position of the anvil can only be fixed by the brakes, and the force of the head cannot be changed. Preferably, the traction member is only on one side of the drive unit, and in this case, it is guided by a deflection roller to a tensioning device having a circumferential groove which covers at least one fixed brake device in the direction of gravity. Lower end. The pulling member is no longer end-to-end between the two tensioning devices, but only one end is fixed to the driving device and the other end is fixed to the tensioning device. When the tensioning device loses tension, the traction members within the drive range are held by the brakes, and at the opposite end there is no need to brake because the traction members there are fixed in the steering. This clamp is simple in construction and can be made at this end. For example, the traction member suspended from the wire is only fixed in a circumferential groove of the 1279465 roller and cannot be discharged. In this case, it is preferable to arrange a plurality of steering rollers together, wherein the gap between adjacent steering rollers is smaller than the smallest cross-section of the traction member in the slit pattern. In this case, the traction member does not unilaterally disengage from the steering roller, 5 because the circumferential groove that turns toward the parent in this field is covered by the adjacent steering roller. Only the outermost deflection roller requires another way of covering. Next, the present invention will be further described by way of several preferred embodiments with reference to the drawings: Fig. 1 is a schematic view of a warp knitting machine having a traction member, 10 Fig. 2: one having multiple tractions Schematic diagram of the warp knitting machine of the piece, Fig. 3: perspective view of the two brake devices Fig. 4: enlarged view of the steering roller at the end of the traction device Fig. 5: VV section of Fig. 4 Fig. 6: VI of Fig. 4 -VI section 15 The first illustration shows a cross section of a warp knitting machine having a jacquard bar and a guide pin 2. A warp knitting machine has, in general, a plurality of jacquard combs, and each jacquard comb 1 has, in general, more than one guide pin 2. However, the warp knitting machine in the first figure is for illustrative purposes only. The 20 guide pin 2 is fixed to the wire 3. When the wire 3 reciprocates, the needle 2 also reciprocates in the traverse direction. The traverse direction is parallel to the longitudinal extension of the wire 3. At one end (to the right in Fig. 1), the wire 3 is guided to the tensioning device 5 via the steering wheel 4, and the tensioning device 5 exerts a tensile force on the wire 3 which is not affected by the distance length. To achieve this, the tensioning device 5 can, for example, be in the form of a cylinder of compressed air 10 1279465. At the other end, the wire 3 is connected to the elastic band 6 by a releasable coupling 7. The elastic band 6 is wound around the drum 8, which is fixed to the starter shaft 9 of the transmission 10. A motor 11 is mounted on the inlet side of the transmission mechanism 10. The motor 51 is an electric motor, preferably a servo motor, a permanent magnetization synchronous motor or a stepping motor. In principle, a motor that can be operated in small angular increments can be used as the motor 11. An electronic control device for operating the motor 11 is not shown. The motor, the transmission and the drum 8 together form a drive unit 21. The wire 3 and the elastic band 6 together form a traction member 12 which is tensioned and fixed by the tensioning device 5 during operation 10. The operation of the motor 11 only acts on the tensioning device 5, so that the transmission mechanism 10 can be started even if the transmission mechanism 10 has play. This play is not affected by the direction of movement of the traction member 12 and is reduced in the same direction. Interference can not be avoided during the operation and starting process. For example, if the supply of compressed air is interrupted, the tension of the traction member 12 will disappear, which may create a risk of the traction member 12 being disengaged from its defined position. In order to eliminate this situation, there is a setting of the brake device 13, which is activated when encountering interference. The brake device 13 has an anvil 14 that cooperates with the head 15. The head 15 is made of a polymeric material. Within a certain range 20 will soften. A guide 16 is attached to the anvil 14, for example, a fork with sharp teeth 17, 18 which extend parallel to the direction of movement of the head 15. The head 15 is driven by the drive cylinder 20 with a ram 19 on which a compression spring (not shown) is mounted. Under the action of no reaction, this pressure 11 1279465 shrink spring will squeeze the head 15 toward the station 14. However, when the ram 19 is operated with an auxiliary energy source (e.g., compressed air), it will leave the anvil 14, so that the head 15 and the anvil 14 are kept at a sufficient distance, and the elastic band 6 is free to move on the opposite side of the stone. The supply of compressed air is interrupted, not only the effect of the tensioning device 5 is reduced, but also the compression spring placed in the drive cylinder 20 can no longer remain in a tightened state, and the head 15 is pushed forward toward the station 14 in the direction of the station 14. And the head 15 is fixed to the anvil 14 below the relay position of the elastic band 6. The guiding device 16 thereby prevents the elastic band 6 from being displaced to one side. The drive cylinder can of course also have other configurations. For example, a magnetic coupling can be placed between the anvils 14 and 10, and the head 15 is attracted by the anvil 14 due to the magnetic force. In this case, it is also possible to arrange a resistance generated by the compressed air in the driving cylinder 2, which resistance can also be formed in other ways, for example, by magnetic force. The drive cylinder 2 can also be constructed as an electric linear motor that overcomes the resistance created by the spring so that the head 15 remains at a sufficient distance from the anvil 14 during operation 15 without interference. However, as long as the interference is tightened and the garment 5 cannot continue to function, the brake device 3 is activated, and the head 15 sandwiches the elastic band 6 between it and the lap. In this way, the traction member 12 can be prevented from leaving its position and thus entangled with the traction member 12 (not shown in detail). 20 I is a comparison case in which the operation is not disturbed in the absence of interference. The same components as those in Fig. 1 are denoted by the same reference numerals. The female traction member 12 is equipped with a dedicated tensioning device 5 at the end, and in the other is a dedicated driving device, on which the drum 12 1279465 the garment 13 is not in operation in Figure 2a. status. There is sufficient spacing between the head 15 and the anvil 14, such that the drive pin 2 at the end of the traction member 12 and the tensioning device 5 at the other end of the traction member 12 actuate the needle 2 The direction reciprocates. 5 Once the pulling force generated by the tensioning device 5 disappears, there is a possibility that the respective pulling members 12 are entangled with each other, for example, from their prescribed positions. This situation can be prevented by the brake device 13, as shown in the figure, which is the state of the brake device 13 at the starting position. The head 15 is moved towards the anvil 14, so that the traction member 12, more precisely the band portion 6, 10 of the traction member 12, is sandwiched between the base 15 and the anvil 14. At this time, the guiding device 16 prevents the traction member 12 from being displaced to one side. Thus, the braking device 13 acts on a plurality of traction members at the same time. In the specific embodiment described in detail, there are six traction members. As a result, the traction members 12 are not only fixed to the opposite side of the warp knitting machine, but are also fixed relative to each other' so that the traction members 12 are not entangled with each other. 15 Fig. 3 shows a specific embodiment having two brake devices corresponding to the brake device 13 of the first and second embodiments. The head 15 can be moved toward the fixed anvil 14, and the traction member between the anvil 14 and the head 15 is not shown here. The drive cylinder 20 of the brake device 13 is fixed to the same bracket 22, and another brake device 23 is mounted. The brake device 23 has an anvil 24, and the head 25 cooperates with the anvil 24, which is driven by the drive cylinder 2A. The drive cylinder 20a is identical to the body cylinder 20 of the brake device 13. The stone occupant 24 moves above the two drive cylinders 2〇b, 20c in the direction of the head 25. The drive cylinders 20a, 20b, 20c are produced in the same manner as the drive cylinders 13 1279465 20 of the brake device 13, but the brakes 26 can only be reached, and the brakes 26 are relatively limited in length. The brake % is fixed on the bracket ^. If the compressed air supply is interrupted now, all of the drive cylinders 20, 20a, 20b, 20c will start. Shizhan 24 will reach the brake 26' via the drive cylinder lion, .5 20c, that is, it will meet the head 25. At the same time, the head 25 will travel in the direction of the anvil 24 so that the traction member 12 between the anvil 24 and the head 25 will be clamped. By the two driving cylinders 2〇b, 20c acting on the anvil 24, the power acting on the anvil 24 is greater than the power acting on the head 25. Thus the anvil arrives at the device of the brake 26, even if the head 25 secures the traction member 12 to the anvil, and remains there. In Fig. 3, it can be seen that the head 25 impacts the two sets of traction members, and each set of the traction members 12 is provided with a plurality of belts stacked one on top of the other. The two sets are of the same height so that all of the traction members 12 can be securely held. Minor errors or tolerances can be compensated for by the flexibility and softness of the head 25. The movability of the station 24 is flawed, i.e., the traction member 12 does not have to be strongly pulled away (e.g., as shown in Figure 2b), and in particular the short traction member 12 will thereby reduce the load. Figures 4 to 6 show only the other end of the traction member. The traction member 12 is guided through the steering roller 4. As shown in Fig. 5, each of the 20 deflection rollers 4 is supported by a bracket 27 and has a circumferential groove 28, a traction member 12 in the circumferential groove 28, and a fixed pin 29 on the bracket 27, and The deepest position in the direction of gravity. The pin 29 covers the circumferential groove 28' so that the traction member 12 does not slip off the circumferential groove 28. The pin 29' also has no contact with the deflection roller 4, so that no additional friction is generated. 14 1279465 5 10 15 20 If the tension of the tensioning device 5 disappears, although the traction member can slide slightly downward under the force of gravity, the traction member cannot leave the circumferential groove 28 on the steering roller 4 because the pin 29 prevents the displacement of the traction member . Another measure, as seen in Figure 6, is that the adjacent deflection rollers 4 have a spacing a which is less than the minimum cross-sectional dimension of the traction member 12 within this range. As a result, the adjacent steering rollers 4 secure the traction member 12 between adjacent steering rollers. Only the outermost steering wheel 4a lacks an adjacent steering roller for securing the traction member, where a pin 30 can be mounted which covers the circumferential groove 28 in a manner similar to the pin 29. There are various variations from these specific embodiments, and the brakes 3, 23 will be more securely gripped than the two sets of traction members, allowing the anvils 14, 24 to be elastic and the heads 15, 25 flexible. Poor or softer, so the inaccuracy of the anvil 14, 24 is acceptable. In addition, it is also possible to move only the anvil 24 and fix the head 25. In addition to using compressed air as an auxiliary energy source, electric power can also be used as an auxiliary energy source to keep the gap between the heads 15, 25 and the anvils 14, 24 continuously open. When the auxiliary energy source is interrupted, the brake devices 13, 23 are activated anyway.
