Figure 18 has shown the embodiment of an electromagnet that the needle selection of knitting needle is controlled.

Fig. 1 is the principal section figure of loom, has shown the integral mechanical structure of machine, and part 1 is a frame, by central parts 3 and annular element 5.Frame 1 supports dull and stereotyped needle-bar 10 and the cylinder needle-bar 11 that is respectively applied for knitting needle 13 and 15.Motor 17 drives by cog belt, is contained in the belt pulley 19 on the power shaft 20, is transferred to roller gear 21 and 22 then rotatablely moving.Gear 22 is transferred to gear 23 to motion, and gear 23 is assemblied on the bearing 24 that is supported by frame 1: gear 23 supports and rotates the device 26 of (becoming counter-clockwise direction in this example) continuously around cylinder 11.Device 26 supports the needle selecting cam that is used to swing selector, and this needle selection device is used to select the following knitting needle that will illustrate 15, and device 26 is simultaneously around 11 rotations of fixing cylinder.Two coaxial all-in-one-piece idler gears 25 that gear 21 has passed through to be enclosed within on the axle are transferred to gear 26 to motion, gear 26 drives axis 27 inhour rotations (reverse with gear 23), the upper end of fixed axis 27 is square position support members 28, its direction of rotation is opposite with 26, ring 29 is assembled on the bearing 30 that supports by the upper end at the middle part 3 of frame 1, ring is equipped with one on 29 around the device 32 that is fixed on cylinder 9 rotations on dull and stereotyped 10 and fluting is so that can hold the swing needle selection device at the knitting needle 13 of following explanation thereon, and said apparatus 32 supports the control triangle of needle selection devices.

Axle 27 is transferred to motion in the device 32 of support plate triangle, in order to promote dull and stereotyped 10 with cylinder 9, axle 27 can move along its axis: in fact, the vertical lifting of axle 27 causes the rising of dish 28, utilize the ring 29, the pan 28 that support by bearing 30 to drive the dish 34 that is fixed on the sleeve 35, sleeve 35 can slide along the center guide part 3 of frame 1, and then promotes dull and stereotyped 10 by cylinder 9.The normal position of axle 27 is gone up definite by the plane 1A that a thrust bearing 36 and a disk 37 are supported on frame.When the lifting of needs axle 27 and dull and stereotyped 10 a few tenths of a mm seldom, can realize needs when this kind is lifted at the about sideline of the so-called elasticity decorative pattern of braiding by pneumatic cylinder/piston system 38.When we wish at the machine stopping period, when checking the parts that are positioned between two needle-bars, be necessary axle 27 is promoted than above-mentioned much bigger distance (order of magnitude is 100mm).This kind lifting can be realized that it all promotes dish 3 and a whole set of machine that comprises dull and stereotyped 10 together by driving cylinder/piston system 38 by the pneumatic cylinder/piston system 39 of big one-level.

Upper component 1C support yarns debatching device 463, it is contained on the coaxial member 40, and utilizes support member 41, makes its rotation.Line from the debatching device was guided by ring 458 before by knitting clamping.This ring is supported by arm 1E by upper component.Support member 1F support cut on the frame 1 and keep cramp iron 483, this folder are used to limit and send out the line of knitting from debatching device 463.

Above-mentioned arm 1E and/or other such as 1G is connected in the needle selection device (as 225) that support member on the frame 1 is used for support fixation like this, and they are distributed in into the device 26 of forward and reverse rotation and 32 outside.

Suction inlet 43 can extend along the pin arc that forms fabric, opens between the edge of cylinder 11 and dull and stereotyped 10.Suction inlet extends into airflow duct 43A with the tensioning of suction air-flow fabric that is weaving and the fabric that transmits after having finished.

More than various assemblies can be controlled by mutual synchronous driver and motor.Various motors are controlled with electronic program, and to guarantee changing its rotary speed in due course, especially at some particular stages, such as the incipient stage, the feeding when crotch end and trousers body begin to form stops the place.Guarantee to reduce its speed.

Other assembly of machine will be introduced and description of drawings hereinafter.

With reference to former loom.Being used to form the parts of coil, also is knitting needle and sinker, basic identical with this loom.With a concrete but unrestriced mode, this patent is selected to be the fixedly sinker that former patent provided shown in Figure 20.With former different parts be:

(1) the pin heel that links to each other with the triangle of control knitting needle motion:

(2) the needle selection equipment because of adopting swing needle selection device to produce, or a kind of direct electron needle selecting system:

(3) needle selection controller, it is by the electronic system control that has an electric gas servo-drive system.

(4) be used to change the height of pin to generate the triangle of coil.It does not exist together is because they are arranged by cover for the two-wire feeding and all are fixed on the device of corresponding rotation continuously, is used in the past that the essential triangle of regulating winding length is small to be cancelled to top offset.

(5) knit the feed system of line.

As previously mentioned, this machine is a circular loom, and its circle diameter is very big, and to hold many fabrics, as many pairs of panty girdles, every pair of trousers have a pair of trouser legs and a trousers body.The loom that will introduce will weave four fabrics simultaneously hereinafter, and this does not get rid of the fabric that weaves other quantity, especially even number spare simultaneously certainly.

In Fig. 2, C1, C2, C3, C4 represent the cross section of four panty girdle trousers bodies respectively.These trousers have certain intervals each other along the circumferential distribution of circular bed.

Fig. 3 has shown the cross section of four pairs of panty girdle trouser legs, is marked with respectively: G1X, and G1Y-G2X, G2Y-G3X, G3Y-G4X, G4X-G4Y has certain intervals equally between them.Fig. 3 has also schematically shown triangle 46 and triangle 47, and they are in outer, interior both sides respectively, are respectively applied for cylinder and flat board, and is become the

device

26 and 32 of both forward and reverse directions rotation entrained.Can see also that from Fig. 3 respectively overlapping triangle is synchronous when rotated, this is so that can pass them from the space between two fabrics.From Fig. 4, can notice, braiding during trouser legs the triangle of reverse rotation can between two trouser legs, pass equally, that is from trouser legs GiX and GiY(i=1,2,3,4) between pass, like this, in Fig. 3 and Fig. 4, can see having 8 intervals can allow triangle pass.Therefore, in order to hold

triangle

46 and 47, all should there be certain width in above-mentioned 8 gaps along peripheral direction, and the

triangle

46 and 47 that starts to control the effect of weaving pin is used for weaving outer, the interior both sides of tubular woven fabric respectively.Every cover triangle is accepted two line feedings, and line is alternately braiding between them, so that compile out two half-coil lines that are connected with each other respectively with the knitting needle on cylinder and the dull and stereotyped needle-bar.

The clothes of wishing braiding are shown in Figure 14 and 15.Begin from toe, at first be made into encapsulated coil line A, C, D, B.This process comprises and is used to weave all required knitting needles of trouser legs (G1X as shown in the figure, G1Y etc.): being next to after the toe is to form a kind of picture half garden corner contours.For this purpose, with reference to Figure 15 and 16, many complete rows are made into, and they are to finish the toes sealing jointly partly by the knitting needle of two needle-bars.Loop A, B, C, D are from A to B, that is they comprise that all are used for weaving all knitting needles of stockings foot and ankle.Yarn is fed the knitting needle of giving two needle-bars, their vertical interlaceds (as shown in figure 16) simultaneously.Cylindrical fabric subsequently, row P is made into, and promptly at first knits the bed braiding at one, and subsequently in another needle-bar braiding, but length is progressively increasing.For example, can take up one's knitting from middle body C-D shown in Figure 15, the length of row P at one end progressively increases with symmetric mode, and the frequency of growth is decided according to the appearance profile of hope acquisition.Like this, just, can obtain appearance profile AC and the DB shown in Figure 14 and 15.

Subsequently, shown in Fig. 3 and 4, the trouser legs with same widths is made into, and this comprises the lower curtate of foot and leg.This part BE as shown in figure 14.After this, in order to make the trousers dress easily, be necessary trouser legs is widened.In order to realize this point, can be along as shown in figure 14 the EF eedles mark length of extension coil line progressively.Except that the method, if at work, can continuously increase the knitting needle of participating in braiding, widening trouser legs can more effective realization, and the increase of pin can simultaneously or replace on two needle-bars, inserts continuously from the terminal of pin arc.After EF finishes, work from reference Fig. 3 and 4 to reference Fig. 2 and 17.Deactivate for two groups in four groups of feed arrangements that possess respectively on two needle-bars.That is, work from status progression shown in Figure 3 to state shown in Figure 17.At this moment, in order to weave F-H part shown in Figure 17, i.e. the jag place of two trouser legs, the knitting needle between two legs is devoted oneself to work.After 46 and 47 2 groups of feeders were deactivated, corresponding feeding also stopped naturally, so just only stays four groups in eight groups of feedings.The knitting needle of territory district F-H on each needle-bar is immediately devoted oneself to work at 1: 1, and interlaced along with knitting needle on two needle-bars just formed the encapsulated coil line that has illustrated in toe section at the F-H place.In the knitting needle of control F-H portion, the knitting needle of controlling one or two adjacent formation trouser legs cloth cover is possible.Be convenient to avoid the edge of FH part mesh to occur like this.Finish after the FH part, just can be from the take up one's knitting fabric of tubular of K-L face.Required knitting needle when the work of this part need weave trouser legs equally, the width of braiding is identical with whole trousers, and this part is known as trousers body (shown in the L-M among Figure 14).Subsequently, braiding elastic cord M-N.This belt can be by the heavy footpath organizational composition on the MM line, and the elastomeric yarn by braiding or a kind of high-count that interweaves just can achieve the goal.This kind knitted the knot structure and known by the expert.

For with knitting needle 13 and 15(Figure 16 of intersecting on two needle-bars 10 and 11) finish and be used to link initial blockade line ACDB and line F, the row of the last coil of H, can adopt the more concrete grammar of following introduction: select identical pin number, promote the knitting needle on the needle-bar 11, but do not feed to yarn, allow knitting needle 13 staggered then, and allow 13 slowly to rise and descend: simultaneously, on the shank of knitting needle 15A, form coil from the line on the knitting needle 13A with the knitting needle 15 that has been raised.Subsequently, thread feed knitting needle 15A reduces it and just forms a coil.Before the braiding trouser legs, can repeat above program.

Loom described here, can produce four pairs of panty girdles simultaneously, at each needle-bar quadruplet two-wire feeder is housed respectively, 8 cover feeder-references are used to show Fig. 3 of trouser legs woven condition altogether, when triangle rotated 1/8 circle from initial position along relative direction after, they just entered illustrated trouser legs crotch region.Above-mentioned motion (shown in Fig. 1 and 17) can not occur when taking up one's knitting the trousers body, this is because knitting needle is just working in the cause of crotch region.Just because of this reason, when braiding trousers body, on each needle-bar, have only two cover triangles in work, thereby the feed line number that provides for every pair of trousers that weaving is two-way rather than four tunnel, is used for the triangle that feeding and coil form and also reduced to four (as shown in figure 17) on each needle-bar.

Fig. 5 has shown the section of needle-bar in the working region, dull and stereotyped section and the section of garden cylindrical shell 11 in the working region.As mentioned above, the formed needle tray of two needle-bars can make knitting needle dull and stereotyped the radially sliding in 13 edges on the flat board, and the knitting needle on the cylinder is slided vertically.

Knitting needle 13 on dull and stereotyped 10 is made up of with needle latch pinhock at contact portion and the common knitting needle and the indistinction of itself and line: but shank is different with common knitting needle, and a lobe 114 is arranged thereon.This ridge is as the support member and the hinge connection of small-sized swing needle selection device or push rod 116, the middle part of push rod 116 have one with the ridge profile phase with groove 117 so that make the two twisting and make 116 can on 114, swing.Knitting needle 13 and push rod 116 are because be limited in the movable chute, thereby they always are in connection status.The front end of swing bar 116 forms a heel 118, is used for and triangle 120,121, and 122 interact with the centrifugal of control knitting needle and entad motion.Pin heel 118 is shown in Fig. 5 in order to be controlled by

triangle

120 and 122, and heel 118 should be pressed into operating position 118X.It can be driven by push rod 124, thereby makes in its sliding tray of imbedding knitting needle fully, and

triangle

120 and 122 just can not act on it more like this.When push rod has been swung and its heel 118 when entering 118X,

triangle

120 and 122 just can act on it and utilize the profile of triangle that it is moved along centrifugal or centripetal direction: utilize hinge 114, push rod 116 just can be passed to knitting needle to its motion, produces required moving so that clamp yarn and form coil.Therefore, the assembly of being made up of knitting needle 13 and swing bar 116 is in running order or off working state, depends on that fully heel 118 is in a high position (FA is consistent with arrow) or low level (arrow FB).When knitting needle when centripetal direction is withdrawn into the rear portion, can be by band 124(such as Fig. 5) along the FB directive effect in it, thereby make it be in off working state.The rising of heel 118 is finished by the selector part that hereinafter will introduce.Dull and stereotyped 10(is the same with cylinder 11) fix, triangle 120,122 and with 124 by a device drive that is in the rotatablely moving of not stopping.Lifting by the selector part that comprises push rod 126 of heel 118 finished.Have two toothrows (as Fig. 6) on the push rod 126, it is accommodated in the groove that is fixed on the cylinder 9 on dull and stereotyped 10, and is fixing by spring 128.Spring allows it to rotate around central pivot point.Lift for the heel 118 that makes push rod 116, the heel 126A of push rod 126 is contacted with push rod 116 according to FA arrow direction.Two covers on the push rod 126 vertical with push rod 116 are selected tooth 126B and 126C, are distributed in the both sides up and down of fulcrum respectively.Tooth 126C is subjected to the promotion of selector, the bottom of push rod 1126 is entered in the groove and groove is left on top, thereby its upper end 126D is contacted with triangle 130, and the profile of triangle 130 just makes 126 to descend by FA arrow direction.The effect of tooth 126B is the aforesaid selection mode of cancellation.Push rod 126 is placed in the groove of cylinder 9.Cylinder 9 is placed on dull and stereotyped 10 regularly.Therefore, when reducing push rod 126 according to arrow FA direction, it just is pressed in the inner radial of small-sized swing bar 116.

On cylinder 11, similar system is arranged also.Push rod 132 is installed on the plane identical with knitting needle 15.Identical with above-mentioned situation, the

push rod

136 and 116 that has heel 138 is similar, but is installed in the groove identical with knitting needle 15, push rod 132.Triangle (as 140,329,381) contacts with the heel of push rod 136, so that it is raised or reduces.For the heel 138 of lifting push rod 136, push rod 132 moves on to position shown in Figure 7 by the FA1 direction from position shown in Figure 6, thereby the inclined-plane 132A on 132 contacts with the heel of push rod 136 and achieves the goal.Moving with push rod 126 of push rod 132 is similar, utilizes two 132B of tooth portion and 132C, and the 132D that contacts with cam 144 just can achieve the goal.

Fig. 6 and Fig. 7 have also shown and have been assembled in two selectors on the

device

26 and 32 that becomes forward and reverse rotation more.They act on the 126B of tooth portion on different circumferential positions, 126C, and 132B, 132C is to play the selection effect.These selectors stretch out from mechanism 148,150,152,154 respectively, act on

push rod

126 and 132, and their relevant position is entered in slideway and the Swing Road.Fig. 8 and 9 has shown one of them (other is identical therewith) of these mechanisms.

Fig. 8 is the plane of a mechanism (as 152).Shown among the figure that bar 217 promotes the bottom that push rod 132 slides to cylinder 11 sliding ways.Bar 217 is contained on the pin, can swing thereon, and by spring 220 tensionings.Above-mentioned all parts are contained on the gripper shoe 221, and gripper shoe is fixed on the suitable whirligig, and has the triangle of controlling selected knitting needle slippage on the whirligig.Therefore, selector 217 rotates in cylinder, can contact (situation of push rod 126 similarly) with all push rods 132.Feeler lever 222 by spring 223 tensionings also is assembled on the above-mentioned gripper shoe 221.By the effect of feeler lever 224, selector 217 is turned to position shown in Figure 9 from position shown in Figure 8, be in off working state this moment 217, the monodentate of feeler lever 222 and 217 engagements.The active position of selector can obtain by the cam finger 121A that adjustment is contained on the plate 121.

Be used for controlling organization 148,150, the single or multiple parts of selector are assembled Fig. 1 with arm 1F(in 152,154) on the fixed support 225 that combines (Fig. 9) act on the feeler lever 122 that it passes through previously.In these parts, comprise bar 226 around pin 227 swings.As by shown in Figure 9, it being pushed to cylinder, turn clockwise just it can drive bar 222, and bar 222 is separated with 217 engagement.So latter's involution is to duty shown in Figure 8.Very clear, the number of bar 226 is with the identical of bar 217 and be in the same plane, so that interact.Bar 226 is by air pump 228 control, to overcome the pulling force of spring 230, to air pump by program control solenoid control.The appearance profile of bar 226 just feeler lever 222 is made corresponding rotation, with the different conditions of control selector 217.

In order to make selector (as 217) break away from duty.Frizzen 224 is pressed 224 directions and is acted on selector 217, thereby makes 217 and 222 to be in engagement.In order to control feeler lever 224, need an arm that is in the state of stretching out 232 by spring 234 tensionings, this arm is by being with 236 to promote overcoming its spring resistance, and connected by the hinge on the frame that is fixed (as 225) 232 with 236 one, and the other end is driven the similar driver 228 of device 240() promote.

The available above less swing bar of introducing 116 and 136 of size of the selection of knitting needle is finished, and is also finished by other system.

Figure 10 is a schematic diagram, has shown the interaction process of the push rod 132,136 on triangle and the cylinder.Its motion represented by FT, but actual be that triangle slides round about.

The triangle of figure middle and upper part is used to control moving up and down of knitting needle 15; The triangle of bottom is used to control the swing of selector 132.

After the heel of swing bar 136 was stretched out from needle tray, the triangle 329-330-331-332-333 that is used to control knitting needle acted on it along straight line 334.When the heel 338 of bar 336 was placed in the groove, it did not contact with above-mentioned five triangles, and they are on the straight line 334, and corresponding knitting needle remains on low level.Do not contact with yarn.Stretching out of push rod 136 heels 138 can be obtained by rising push rod 132.Push rod 132 resets into low level and can be realized by the middle ridge 132F that two horizontal triangles 334 act on push rod 132.When the low side 132D of extension bar 132 stretches out chute and triangle 144 or 336,337 contacts, just can realize the rising of push rod 132.Triangle 144 is raised selector 132, push rod 136 is rotated, thereby heel 138 and triangle 329 are contacted, and the result is that triangle raises with corresponding knitting needle.Correspondingly, by triangle 336 knitting needle is risen from triangle 330: knitting needle is risen from triangle 332 by triangle 337.What be used for making selector 132 and triangle 144,336,337 contacts is respectively selector (as Fig. 8,217 in 9) 317,338 and 339.The effect of bar 318 is to make bar 132 be in off working state.

The triangle 329 that is used for knitting needle, 330,331 form first feeding, its motion by respectively with bar 317,338 and 318

corresponding triangles

144 and 336 decide: the

triangle

332 and 333 that is used for knitting needle forms second feeding, and it moves by deciding with bar 339 corresponding triangles 337.In the formation of coil, triangle 329,330 and 332 is a rise cam, and 331 and 333 is cast-off cam.In operate as normal, the yarn of two kinds of feedings is different.Triangle 329 and 331 also can be with reference to Fig. 6 and 7.

On the top of Figure 10, can see

outline line

340 and 341, their representatives are lifted by

triangle

329 and 332 respectively and the needle point track when being reduced by 331 and 333 respectively.

The feed arrangement that is used for first feeding and second feeding be respectively hook 342 and 343(they with heel and pin by the relative motion of FT direction, but actual and triangle inverted running) dotted

line

344 and 345 represent respectively by hook 342 and 343 hello to the yarn positions of knitting needle.

Figure 11 and Figure 10 are similar, have shown triangle and the selector 116 of

flat board

10 and 126 interaction process.Its difference is that the half-twist on the basis of Figure 10 of some part in the region R, knitting needle 13 are in level rather than are in plumbness as bar 126, and these parts are arranged around dull and stereotyped 10 center camber line LP.The top of figure is that triangle 130 and other act on the part of push rod 126 top 126D.The parts that these parts are formed are driven downward together by triangle, thereby the bottom of bar 126 is contacted with corresponding position on the push rod.Profile 384 is parallel with heel 126F and bar 126.The motion of push rod 126 consistent with the direction of motion fP of triangle (in fact triangle is along the inverted running of fP).Feeler lever 368,389,388,367 function respectively with Figure 10 in 318,339,338,317 similar.Triangle 120,122(also can be with reference to Fig. 5 and 6), 380,382,383 function respectively with Figure 10 in triangle 329,331,330,332,333 is similar.Triangle (120 or 382) also shows in Fig. 5 and 6.Similar with hook 342 and 343,

hook

349 and 350 was clamped yarn before 342 and 343, and guided them according to straight line 344 and 345.A coil is finished in succession by the knitting needle on two needle-bars, and coil should be continued by another needle-bar after a needle-bar is finished, and at this moment, must correspondingly hand over to yarn on another hook from a hook.This process will be introduced hereinafter.

In Zone R the arranged direction difference of part, Figure 11 relevant with dull and stereotyped 10 and with cylinder 11 relevant Figure 10 identical comprises the function of part.

For knitting needle being moved to the two-way feed line, this weaving loom provides dual cam system (329-331:332-333:120-122:382-383).Every road feed line all has the yarn feeding of himself.These dual feed systems are convertible into the substance feed system.Each system represents a single channel feeding, provides two different strands of number, stowing stitching pine to weave short.

Based on the two-way feed system, this loom has the ability to handle two kinds of different yarns, forms a kind of like this coil tissue on two needle-bars, and it has two strands of spirality coil cross columns that overlap mutually.This tissue can be used to produce the product that a kind of expert knows, and it is made up of the alternate coils line, and row be left-handed line (the anti-wheel) (S) and dextrorotation line (Z) form.This ability helps making the known second kind of product of expert, and it is by mutual overlapping, is made up of the row that non-twist anti-opinion and elastica (as Lycra or similar line) form.So just, can make elastic clothes.

As mentioned above, this loom also can be used to make the another kind of product of knowing in the one's own profession.Formed by the decorative pattern coil dark streakline mark of pine by having short for this product.This woven structure is equally with two strand manufacturings.In this case, the type of two strands identical (being generally nylon) but number do not wait.In identical feeding, two strands are fed just can obtain this tissue to knitting needle, that is raising selectively (utilize triangle 329 to act on part knitting needle and 332 and act on remaining knitting needle) and reduce (by triangle 333) together by knitting needle just can obtain this tissue.For this purpose, be necessary the structure of the triangle that acts on knitting needle is done some little adjustment.Because feed system all has two cover hook 342-343 and the every cover of 349-350(to be responsible for one tunnel feeding) be used for the yarn feeding, thereby be necessary the two is united two into one.That is, raise selectively and decline together by knitting needle, the two-way feed line is all clamped by knitting needle.

This problem can solve by of removing in two cast-off cams.As Figure 12 (cylinder needle-bar) and the dull and stereotyped needle-bar of 13() shown in, two original cover triangles (as Fig. 1 and 11) 331,333 and 122,383 have been removed two respectively: 331 and 122.

In textile industry, the mode of production of the stowing stitching decorative pattern of pine is by called optical imaging about lacking.That higher strand of number is at first clamped by a plurality of knitting needles, raises and knits line according to the selection that performs in advance (it embodies pattern), and on the different position of angle, the less line of other number is clamped by all knitting needles then.With reference to Figure 12, this loom is the above-mentioned task that realizes like this: according to the selection that performs in advance on the triangle 329, raise a plurality of knitting needles and make them by track 340 motions and clamp line 344, other knitting needle is raised along track 341 with triangle 332 and is moved.The above-mentioned selection that is used to weave desired pattern can be realized by the combination of

bar group

317 or 317 and 318.Be exactly specifically, above-mentioned bar group makes triangle 144 promote the selector rising, and triangle 329 promotes the knitting needles rising as a result.Other selector utilizes single bar group.339 make triangle 337 promote its rising: in this case, only need single bar group, because other all selectors must be elevated under the situation that does not need any selection.Line 345 is raised and clamped to suitable knitting needle by triangle 332, and its syringe needle track is 341.Knit line 344 and at first feed and give, the knitting needle that is at first lifted is clamped the knitting needle that they will can not lifted subsequently again and is clamped, because thick line will pass through after them.

Identical in the forming process of pattern on the dull and stereotyped needle-bar and above-mentioned process on the cylinder needle-bar.The schematic diagram of these triangles is seen Figure 13.Lack triangle 122 as we can clearly see from the figure.

Above refer to this loom many clothes of can weaving simultaneously.Be 4 in this example.When knitting thread breakage, ongoing work just is deadlocked.This is the optional advantage freely place that is provided by said mechanism.Particularly

heel

118 and 138 outside motion have stopped, and so just can avoid the damage of needle latch.

It should be noted that when

heel

118 and 138 withdrawals when avoiding acting on knitting needle, the knitting needle that is not directly provided by heel can be provided above-mentioned layout.Tensile force on this coil that can avoid linking to each other with the off working state knitting needle, those are used to control the triangle of knitting needle, and particularly the triangle of control reduction knitting needle keeps motionless.This layout has prevented the tensile force on the coil, has avoided then knitting the danger of thread breakage, and has not needed to be used to control the movable triangle of knitting needle.

Knit line in order to provide, native system provides the feed arrangement on the

device

26 and 32 that is connected in into forward and reverse rotation.At first, drive one of them feed arrangement, allow and knit line, make it then to stop, drive another feed arrangement simultaneously, knit line from opposite direction feeding along a direction feeding.In this way, alternately feeding just can realize, thereby is made into tubular fabric.The feed motion of each needle-bar is only rotated to not needing along positive and negative both direction alternate rotation along a direction.

In the loom that the present invention carried, feed arrangement at the hook of Figure 10 to 13, utilizes mechanical device to realize above-mentioned motion.The design of described hook is special.Figure 18 to 20 has shown different feed arrangements, and these devices provide different yarns jointly.Thereby these devices are knitted the line sorter with other and are cooperated, and with assurance the identical line of knitting is at first fed to each needle-bar, and then another route is fed to needle-bar, and the weaving direction on two needle-bars is opposite.

On the feeder with knit the part that line directly contacts and be made into hook-shaped.They are that 342 and 343(in Figure 10 and 12 is responsible for first and second feedings on the cylinder respectively), and 349 and 350(in Figure 11 and 13 are responsible for first and second feedings on the flat board respectively).

That other mechanical structure of the machine that the present invention does not relate to is carried out simultaneously at other, with in identical inventor and the identical patent that everyone was done please in (disclosures in Italian patent application N9357A/89) be described.

Have a kind ofly can replace method contemplated among Fig. 5-7, needle selection is that originally on one's body

little needle jack

116 or 136 is that finish rather than finish by 126,136 by being contained in knitting needle.Figure 18 shows that the needle selection process controls with electromagnetic system.In this system,

needle jack

116 and 136 is controlled its swing by corresponding feeler lever.Feeler lever is by magnet control, and electromagnet is driven by timer successively, makes it and becomes both forward and reverse directions whirligig (triangle of mobile knitting needle is housed on it) synchronous.

When the knitting needle selected on dull and stereotyped 10, the instrument that is used for swing bar 116 is a feeler lever 577, and it comprises arm 577A and has round portion 578 as fulcrum.Arm 577A can be attracted by small magnet 580, and whole feeler lever 557A-557 is rotated around fulcrum 578.So arm 577A reduces, depress the afterbody of push rod 116 and its heel 118 is raised, so that allow knitting needle 13 be controlled by triangle.The groove that above-mentioned feeler lever 577 is contained on wheel 582 circumference is interior and fixing by elastic webbing or spring 519, and wheel 582 is fixed on dull and stereotyped 10.

Because in question machine is mainly used to weave the fabric of high fineness, the distance between the knitting needle is very little, and the space that is used to hold electromagnet 580 is also little, thereby these electromagnet can not be held by the space between two knitting needles.For addressing this problem, can be electromagnet with two or more rows be staggered (as Figure 39).Therefore, feeler lever 557, its arm are 557B, will be attracted by electromagnet 581, and it is inserted between two feeler levers with contact arm 557A.

The knitting needle that method similar to the above also is used to solve on the cylinder 11 is selected problem.Feeler lever 583 can force down push rod 136, and the arm of feeler lever has two kinds: 583A and 583B are attracted by electromagnet 585 and 586 respectively, and are arranged in alternately on the two different rows.

This needle selecting system compares to the advantage that system had that begins to introduce: reduced two sizes that become both forward and reverse directions whirligig 26 and 32 greatly.Because only depending on the triangle of controlling knitting needle, size at this moment has nothing to do with the needle selection device shown in Fig. 8 and 9.The size of the cylindrical shell 582 on the cylinder 11 and dull and stereotyped 10 reduces than original

cylindrical shell

11 and 9 is also corresponding.Except that

feeler lever

577 and 583, other part relevant with selecting knitting needle remains static without exception.

We know that what above accompanying drawing was showed only is an one exemplary embodiment of this patent.Provide these accompanying drawings just in order to specify this patent.Fully can be in the scope that does not exceed the patent design philosophy, the shape and the arrangement of some parts changed.Writing out relevant reference number in the claims is under the situation with reference to explanation and accompanying drawing, and the reading of claim is become easily, and the appearance of these reference numbers does not limit the protection domain by the claim representative.
