Produce carpet with half leno method, several yarn access node methods are arranged, especially the suede warp on one or more warp thread.Single or the doubled yarn that these yarns can adopt silk, hair, cotton, spun gold, filamentary silver or other mineral fibres or synthetic fiber to be spun into.Turkey's knot shown in Fig. 1,2 and Ji Aode knot usually are used for binder yarn.Lucky Order is tied its characteristic and is that yarn is positioned at same plane (Fig. 1) or Different Plane (Fig. 2), and warp thread 1 and the warp thread 2 adjacent by the coil encircling of remaining silent merge.Opposite Persian knot or gloomy receive its characteristics of knot (Fig. 2) be yarn with the coil of remaining silent around first warp thread and with open stich doubling on second warp thread 2.First and second warp thread can be positioned at same plane or two Different Plane.Can tie with lucky Order by the method for the present invention, its effect is the same good with the gloomy knot of receiving.

Fig. 4 is for to represent equipment of the present invention with perspective method.This device comprises a yarn distributor 3, and its effect and a printer class that has a print bar are seemingly.Yarn distributor has a series of blank pipes, and it is arranged on the taper seat in equidistant mode, and taper seat is to be R by radius of a circle _AAnd R _B, be positioned at two vertical planes separated by a distance (a, b).The outlet of each pipe preferably is with arc that yarn is had good positioning slightly, and is more detailed as can be known hereinafter.

Adorning the yarn 5 of a bulletin colour in every pipe.On the one hand, each root pipe is by adopting double-curved surface hole 6, is contained on the gripper shoe with XX ' axis quadrature, is positioned at bar 8 one ends of piston 9 or electromagnet on the other hand by a hinged fork 7.Control piston or electromagnet 9 are positioned at plane 6b and X-X ' axis normal, and are that b face and XX ' joining are radially and are provided with respect to the B point.

Available artificial or (partly) the automatic form of the control of piston 9 or electromagnet.In " system front end " device, its control can be implemented by computer program.

Bring XX ' axis into for dyed yarn, make the action of corresponding piston formula electromagnet appointment.The radial motion of fork 7 makes its motion at the end, and pipe 4 ports of export are positioned on XX ' axis.In the embodiment of Fig. 5 and Fig. 6, guide pipe 4 is installed on bar 8 ends of piston 9 rigidly.The other end of guide pipe is connected on the plastic tube, and this plastic tube is used for for yarn.Plastic tube can be followed bar 8 motions of piston 9, each piston 9 and XX ' axis oblique easily.By back one embodiment, piston is located at axis X X ' symmetry and has on the conical surface of summit B.

When yarn-guide tube was lower than XX ' axis, dyed yarn was brought yarn-guide tube into this quadrat method, and promptly loose thread 10 stretches out certain distance and is enough to from the yarn-guide tube free end and held by yarn gripper.Yarn gripper is doubling parts 11(Fig. 4) a part, two

bullets

12 and 13 on

lever

14 and 15 form by being installed in,

lever

14 and 15 is installed on first disk 16, this armor rotates around ZZ ' axis.Can know and see for yarn being brought into doubling mechanism, yarn gripper can by one traditional, the yarn gripper that has two arms grips dyed yarn.

Fig. 7 represents another embodiment, and doubling parts 17 are that axis is installed in second disk, 18 tops with LL '.Second disk has a web 20, has one at least, preferably several fenestras 19.As shown in Figure 8, the fragmentary cross-sectional view that coils for the limit.Here dish extends upward and hides at least the part of doubling parts 17, and doubling parts 17 are positioned at this zone but are not packed on second disk and do not rotate with second disk.In each both sides, fenestra center, the

spring

12 and 13 that is positioned on the limit dish of second disk has been formed two gripper members.When the second disk turning handle yarn was brought a pair of warp thread front into, fenestra allowed the doubling device 17 of front to pass through once.Second disk, 18 1 ends are installed in the driver plate that links to each other on the axle and with motor as first disk 16 and enter revolution.

In order to cut off yarn 21, be commonly referred to as the suede warp, comprise a yarn cutting parts 22(Fig. 7 by apparatus of the present invention) be installed in the yarn distributor exit.For instance, the yarn cutting parts comprise a blade, and yarn is gripped the back blade by yarn gripper and beats to shock point 23.Shock point 23 is the parts that belong to disk 16 or 18.When this kind yarn cutting parts use, make that yarn improves the regularity of access node in this manner with on the circumference of single suede through being arranged in disk in the same plane.In the example of Fig. 7, when cutting off yarn, disk rotates at every turn, and rotational angle is β.During turning, yarn gripper clamps the yarn end of selecting for use and holds.After waiting to turn round an angle beta, the effect of yarn cutting parts is also cut off yarn, and yarn is gripped by

gripper member

12 and 13 then.After moving angle beta of the first disk revolution and yarn cut off in Fig. 4 example, yarn was gripped by

spring

12 and 13, and

spring

12 and 13 is each activity doubling parts part of the whole.Among another embodiment, the yarn cutting parts that exemplify are made up of a pair of scissors.

Fig. 9 represents that these parts comprise a

yarn clipping spring

12 and 13 as mentioned above, are installed on

lever

14 and 15 by first embodiment of doubling parts of the present invention.The yarn clipping spring preferably is installed in the groove on the lever end.Example medi-spring 12 is left-handed springs, and spring 13 is dextrorotation springs, and lever 14 is linked to each other with plate 26 with 25 by bar 24 respectively with 15.These lever centers lay respectively at 27 and 28.At (Figure 10) between doubling action period, plate 26 moves forward into XX ' axis direction along YY ' axis.Bar 24 and 25 gives

lever

14 and 15 1 power, and makes them around axis 27 and 28, and multi-folded yarn line 21 is gripped by spring.Be actually by the U type and be centered around on warp thread 1 and 2, promptly will be combined into one by this method loose thread.In this doubling on, the lever displacement is to be for loose thread is brought into desired location in order to make the yarn clipping spring leave the circumferential edge of disk 16, to link mutually, and plate 26 motions are by piston or magnet control (not showing in the drawings).

When with second disk 18(Fig. 7) time, the front portion of yarn clipping parts is passed fenestra and is caught loose thread doubling then.After this action, the gripper member front end withdraws from and makes the disk rotation and provide another fenestra to act on another yarn then.

Figure 11 represents by second embodiment of doubling parts of the present invention.In this mechanism, the doubling parts comprise that two push away tongue and by plate 26 and bar 29 and 30 effects.Bar 29 with 30 respectively with push away tongue 31 and link to each other with 32, it is jagged 33,34 that each pushes away lingual ribbon, takes the shape of the letter U or V-arrangement or the two is in conjunction with shape.Yarn is positioned at breach, and is in fact parallel with plate 26.In the doubling process, plate makes the yarn between breach merge so that yarn mutually combines by U-shaped forward by the loose thread direction, and breach maintenance yarn is located correct and prevented to tie mutually.

The mechanism of Figure 12 and the 3rd embodiment of 13 doubling parts of expression, lever 35 and 36 rotates around axis 37 and 38 here.Above-mentioned lever has the effect of a similar hand, and their promote yarn and yarn is taken the shape of the letter U and close.

Figure 14 and the 4th embodiment of 15 expression doubling parts, this lever profile is cam 39,40 shapes.Lever doubling effect is acted on ball bearing 41,42 ends and is finished by a fork 43, is by working with the concentric tempering spring of two rotating shafts and open.

In order to obtain the yarn different length, distinct methods is arranged here.First or

second disk

16,18 is replaced with diameter disk by another respectively but the doubling parts are different with fenestra, and in the case, the angle of revolution of disk is with change.The angle of revolution of disk and keep constant with the yarn number in addition, in the case, the disk diameter that substitutes shortens with yarn and reduces, and increases with yarn and strengthens.

In order to make binder yarn around two warp thread, comprise a displacement component by apparatus of the present invention, first warp thread and second warp thread are moved to yarn 21.Specify as Figure 16 and show, displacement component is made up of piston 44 and is subjected to displacement in the warp thread surface range, and piston head two consecutive warp 1 of 44 promotions and warp thread 2 are towards yarn 21 access nodes.The warp thread opposite side is not piston (Figure 17) to be installed and a pair of hook 45,46 is housed.These hooks are installed on the

motor

47,48, preferably make hook produce two warp thread that yarn and mobile avris are clamped in swing with electronic or air motor, before warp thread is pushed to by piston.Under the hook, for warp thread, being arranged in the same side has access node yarn gripper 49 and is contained in (figure is demonstration not) on the movement parts, and the access node yarn gripper is brought between the warp thread, and warp thread is hooked and made the access node yarn gripper to move back and forth with respect to hook by hook.

In order to tie binder yarn with Ji Aode, can use by the inventive method, suede through selected be to select bag yarn in the yarn-guide tube by moving piston.Piston makes the yarn-guide tube displacement by this quadrat method, and promptly yarn stretches out from yarn-guide tube and clamped by doubling parts yarn gripper.In concrete mechanism, the doubling parts are positioned on first disk 16, and the disk motion is also rotated an angle (β), and the result will pull out the loose thread in the yarn-guide tube.Loose thread is acted on and is clamped by

yarn clipping spring

12 and 13 then.When disk rotated an angle beta, revolution finished and by 22 effects of yarn cutting parts selected dyed yarn 21 is cut off.Bent fenestra rotated together before second disk 18 was clamped yarn and driven the doubling parts.

When yarn is cut off, be brought to the warp thread front side around also knotting.Realize by disk 16 rotations in this example.When yarn 21 is positioned at warp thread 1 and 2 fronts (Figure 16 and 17), in swing hook 45,46 1 sides, piston 44 enters action.Piston head 44 also promptly moves as shown in figure 18 to swing hook 45 and 46 to the yarn direction motion together to selected warp thread 1 and 2 motions.Swing hook (Figure 19) acts on two consecutive warp then, and purpose is to work the yarn effect of catching during warp thread is travelled forward.The motion of hook is to be caused by two on the

motor

47 and 48 relative miniature couplings effects.Each hook all has swinging axle separately, and when hook drew warp thread, swinging axle was automatically pushed the warp thread side to.As shown in figure 20, hook is pushed warp thread to a side simply, and the access node yarn gripper is passed through between two selected warp thread.

Two warp thread 1 and 2 are finished after yarn 21 displacements, and in fact the latter presses the U-shaped doubling.Because of stating that in front plate 26 is pushed the loose thread side to, lever shaft rotates around the axle center separately.Loose thread is pressed U-shaped as shown in figure 10 on two warp thread.

Figure 21 and 22 expression access node yarn grippers 49 move upward between two warp thread by U-shaped and the loose thread that closes in order to clamp two.When access node yarn gripper 49 was clamped yarn two statures, hook 45 and 46 was got back to the home position, and promptly open position as shown in figure 22, discharges warp thread.The access node yarn gripper is downwards after (Figure 24), with being shaped but not have bottom the tieing of tension pulls to.Figure 24 represents that also the head end 45 of piston 44 also withdraws from, and discharges warp thread then fully when hook discharges warp thread.This moment, the former access node yarn gripper that is positioned between two warp thread is thrown off and is continued to move downward.During moving downward, tieing is tightened up gradually.When access node yarn gripper motion arrival bottommost, shown in Figure 25, tieing acts on the existing weft yarn 52 and is close to fully.The loop ends of yarn access node, access node device will move upward and clamp other yarns and do to repeat the access node action.

In order to make a complete carpet, method is bit by bit to carry out access node by displacement, and each piston, joint are clamped device, hook even doubling parts and be parallel to the warp thread face by predetermined distance, more than all concerning each tieing.

In order to beat the gloomy knot of receiving, can adopt similar approach, in any case, yarn at first warp thread by the coil form of remaining silent around yarn, and second warp thread by open stich around and close.

Figure 26 and Figure 27 represent first and second the enforcement illustration by weft yarn successively.Between two row's tieing, one, two even three weft yarns are arranged usually.Usually introduce these weft yarns with artificial by root, never adopt mechanization.Under all situations, weft length will substantially exceed the width of carpet at least.Manual operations is very slow.By the inventive method, the purpose that weft yarn is introduced by waveform is to make weft length surpass carpet width.Figure 26,27 for example,

weft yarn

50 and 51 is pressed sawtooth waveforms and sinusoidal wave the introducing respectively.The edging of broadwise allows to use weft yarn and be easy to.
