Slender bodies 150 is located immediately at the bottom of each

cutter

31,32, and it is configured to, and position SUL and cutter spacing are when it goes up position HLL down on it when slender bodies 150 is positioned at, and (Fig. 4 a) between flange 152 for the relative pinning body 161 of two rows.

All be provided with a series of vertical channel 156 on the vertical face in the outside of slender bodies 150, each groove 156 can hold the corresponding bar 11 of combining and slide within it.

Each comprehensive bar 11 comprises that a shoulder 120 is used for limiting stop body 20; This shoulder 120 to both sides partially be positioned at slender bodies 150 on join and take on 121 and engage.When shoulder 120,121 joined, locking device 35 (being a breach 135 among Fig. 2) was positioned at the bottom of flange 152.Therefore, in this position, locking device 34 is prevented from being connected with locking device 35.

If combine bar 11 selected its top shed positions that rise to, it is maintained at its IP position.Therefore because slender bodies 150 to its SLL position motion, pins body 161 and withdraws from flange 152 (Fig. 4 b), pin breach 135 and exposed.Therefore, pin body 161 and outwards move with comprehensive bar 11 and couples together, when

cutter

31 or 32 rises, the relevant pinning body 161 that is carried by cutter engages with the breach 135 of selecteed comprehensive bar 11, will combine bar position HUL on it and move.

Be provided with selected its top shed position that rises to if combine bar 11, it does not just remain on its IP position.Therefore when comprehensive bar when its next SLL moves, combine bar 11 and keep joining with slender bodies 150, the breach 135 of relevant comprehensive bar 11 withdraws from Shi Buyu pinning body 165 joints at lock body 165 from slender bodies 150 (Fig. 4 c).

The comprehensive bar holding device 51 of each comprehensive bar 11 comprises a hook-shaped pinning body 153 that is positioned on the elastic arm 154 in first embodiment 100.Arm 154 is fixed on the printed circuit board (PCB) 180, and is made by an elastomeric material, is convenient to pinning body 153 is biased into the non-pinning position of next-door neighbour's plate 180, and pinning body 153 with this non-locked position can not lock together with the locking device device that is positioned on the comprehensive bar 11.Pin the body 153 selectable locked positions that move to, this position and printed circuit board (PCB) 180 separate a segment distance, is positioned on the mobile route of the locking device of combining bar 11, is convenient to engage with this locking device.

Pin body 153 and move to its locked position by an electromagnet 182, this electromagnet is fixed on the printed circuit board (PCB) 180, and is fixed on permanent magnet 183 interoperations on the arm 154.When exciting, electromagnet 182 places promote permanent magnet 183 to its locked position.Best, as shown in FIG., electromagnet 182 is an annular, and it has a hollow 186, for hold permanent magnet 183 when pinning body 153 in its non-pinning position.

As an alternative method, also arm 154 may be arranged to pin body 153 and be partial to its locked position, and electromagnet 182 attracts permanent magnet to move to its non-pinning when excited state.

The another one alternative method is electromagnet 182 selectable 153 arrival of mobile pinning body its pinning position and non-locked positions that excite active.In this structure, arm 154 needn't be made for elastomeric material.

Shown in Fig. 2 a, electromagnet 182 can be fixed on the arm 154 and permanent magnet 184 is fixed on the plate 180.

Best, each magnet 184 is surrounded by a soft iron ring jacket 186, and this sheath keeps magnetic to contact with magnet 184.This sheath 186 is used for limiting the passage of a magnetic flux, thereby provides a strong attraction/repulsive force between electromagnet 182 and the permanent magnet 184.Sheath also is used for shielding those skimble-skamble magnetic flux by adjacent electromagnets 182, therefore can make electromagnet 182 solid matters.Sheath 186 also can be contained on the arm 154 in device shown in Figure 2, is used for surrounding magnet 184.

It is contemplated that also each pinning body 153 can be moved by the manipulation of other electronics driving device between its pinning and non-pinning position, such as a kind of electrostriction bar.

Printed circuit board (PCB) 180 is combined bar 11 along each row and is extended, and pins body 153 for each comprehensive bar of every row carries one.The arrangement that the electromagnet that preferably links to each other 184 is staggered makes adjacent pinning body 153 solid matters like this.Each printed circuit board (PCB) 180 is positioned on the rigid mounting 187, and this rigid mounting 187 is fixed on the mainframe of mechanism, and the most horizontal part 188 of what a bottom carries independent guide member 189, is used for guiding the lengthwise movement of each comprehensive bar 11.

The pinning body 153 that is connected with each comprehensive bar 11 can exercisablely will be combined bar 11 and remain on its top shed position and its interposition IP.Therefore, only need a holding device 51 to select to combine the rising of bar 11 and grip it and be positioned at the top shed position.

In embodiment 100, to combine bar 11 and generally be made of plastics,

locking device

52,56 is integral cast with it preferably.

Fig. 5 and Fig. 6 describe the part of second embodiment 200 in detail, and second embodiment 200 is second embodiment, second drive unit 50 with the difference of first embodiment 100 and pins connection control device 40 and adopted different structures.It has also adopted identical comprehensive bar holding device 50, thereby no longer does explanation herein.Drive unit 50 in Fig. 5 comprises an elongated supporter 250, has 260, the cam bodies of a plurality of cam bodies 260 on this supporter and links together with supporter 250 by a flexible preferably flexible arm 261.

Every row combines bar 11 all supporter 250, and this supporter is combined bar along every row and extended.

Each comprehensive bar of combining in the bar a row who is being connected with supporter all provides a cam body 260.Locking device 35 is fixed on a kind of form of pinning body 235 and combines on the bar 11, and this pinning body 235 has the pinning abutted surface 236 of prone inclination, and this abutted surface is projected on the both sides of combining bar 11.

Cam body 260 has a bearing that makes progress 237, leans against on the bearing 237 at abutted surface 236 under the effect of spring 17 (not shown).Bearing 237 covers abutted surface 236 in this manner, and the pinning face that makes progress 234 that promptly is positioned on the

cutter

31,32 can not engage with bearing 237.

Combine bar 11 by flexible, best flexible material is made, and combines bar 11 and is guided as follows promptly on the operating path that when combining bar 11 and do not having deflection pinning body 235 is positioned at pinning face 234 (Fig. 6).

Cam body 260 has side convex surface 238, it is positioned at the bottom of bearing 237 this convex surface 238, with be positioned at cutter 31, convex surface 240 interoperations on 32, can will combine bar 11 and deflect into the non-pinning position of the deflection of combining bar 11 (Fig. 5) to both sides, this deflection action is to occur in

cutter

31 or 32 to drop to its low level KLL, and when combining bar 11 and being positioned at its interposition IP.

There is not selected rising if combine bar 11, be that it is not held device 51 and remains on interposition IP, supporter 250 can move towards its low level SLL, the comprehensive bar 11 that is attached thereto is also hauled motion, and because pinning abutted surface 236 is blocked by cam body 260, can not be bonded together with locking device 234 pinnings so pin body 235.If bar 11 is selected does ascending motion, promptly it is held device 51 and keeps position IP therebetween, then in elongated support 250 when its low level SLL move, cam body 260 can and pin body 235 and

cutter

31,32 separation.Thereby comprehensive bar 11 can get back to the locked position of its non-deflection under the deflecting force effect of its intrinsic deflecting force and/or elastic arm 261, thus when

cutter

31,32 rises, pins body 235 and pins between the body 234 and will engage (Fig. 6).

Get back to its low level KLL in order to separate from

cutter

31,32, supporter 250 is towards its upper SUL motion, and cutter 31,32nd descends.Thereby when

cutter

31,32 passes through the supporter 250 of rising, pin body 235 and will sit cam body body 260, thereby separate from the cutter that descends.

As shown in Fig. 5 and Fig. 6, combine bar 11 and preferably make such as spring steel by the elastomeric material of elongated strip, and by being positioned at a breach guiding on 260.Combine the guiding of bar 11 by cam body 260 be used for guaranteeing pinning body 235 correct on the cam body 260 and guarantee to combine positive be displaced sideways of bar 11 between its pinning and non-pinning position.Can expect combining bar 11 and also can be made by plastic material, the comprehensive bar 11 of deflection is returned to its deflecting force of pinning the position mainly to be provided by elastic arm 261.

The 3rd embodiment 300 illustrates in Fig. 7.It is similar to embodiment 200, and combining bar 11 is to be displaced sideways, and is used for making being positioned on the

cutter

31,32 and being positioned at the locking device of combining on the bar 11 that cooperatively interacts engaging/break away from action.And, in the 3rd embodiment, adopted and implemented just 100 identical holding devices 51.

In the 3rd embodiment, second driving device 50 comprises an elongated bodies 350, and it is fixed in, and (not shown) is used for moving back and forth on the moving direction of

cutter

31,32 on the shelf, and also can reciprocating motion on perpendicular to the moving direction of

cutter

31,32.

Combine bar 11 and have one and pin body 235 and be similar to embodiment 200, but its gear-stopping bar 320 that had open in one fen not in addition, it is used under the effect of spring 17 deflection and elongated bodies 350 and joins.Preferably each comprehensive bar 11 is done guiding longitudinally by the corresponding breach that is positioned on the slender bodies 350, and on described vertical direction during reciprocating motion, comprehensive bar 11 is done positive being displaced sideways with convenient elongated bodies 350.

Also being in its first lateral position (showing as Fig. 8 a) when elongated bodies 350 is positioned at its low level SLL combines bar 11 herein and is guided and is in its non-locked position with respect to cutter 31,32.Thereby, guide when interposition IP rises by elongated bodies 350 when comprehensive bar 11, pin body 235 and

cutter

31,32 in laterally spaced one enough distances, thereby guarantee joint can not take place to pin between pinning

body

235 and 234.

When elongated bodies 350 beginning when its low level SLL returns, elongated bodies 350 remains on its first side direction position.During it returns or when it is positioned at its low level SLL, elongated bodies 350 side direction (shown in arrow B among Fig. 8 a) move to second lateral position (Fig. 7,8b), combine bar 11 herein and move its locked position of arrival to

cutter

31,32.

Elongated bodies 350 remains on its second lateral position till elongated bodies 350 is again when its upper SUL rises, and elongated bodies 350 revert to its first side direction position at this moment.

If combine bar 11 selected rising (8a, 8b), combine bar 11 and remained on comprehensive bar centre position by comprehensive bar holding device 51, be positioned at the relevant cutter 31 that is mated so that pin body 235, the top of the locking device 234 on 32, and comprehensive bar 11 is displaced sideways to enter by elongated bodies 350 and pins the position when comprehensive bar rises on it position, with

corresponding cutter

31,32 are bonded together, there is not selected rising if combine bar 11, when comprehensive bar is positioned at 11a state shown in Figure 7, it can not be held position IP therebetween, so get back to its low level HLL.

Combine bar 11 and cutter 31, the 32 disengaging connections of moving towards its next KLL in order to make, elongated bodies 350 rises to its SUL position when

cutter

31,32 descends, and 350 of elongated bodies are positioned at its first side direction position.

Thereby when

cutter

31,32 passed through elongated bodies 350, backstop 320 was connected with elongated bodies 350.Thereby will transfer on the elongated bodies 350 by

cutter

31,32 support of combining bar 11.

Showed another one embodiment 400 in Fig. 9, it has used the holding device 51 identical with embodiment 100, and the pinning that the lateral deflection of comprehensive bar 11 is controlled between

relevant cutter

31,32 and the comprehensive bar 11 engages.

In the 4th embodiment 400, a given row combines in the bar, and first comprehensive bar 11 is positioned between a pair of auxiliary cutter 451,452, and this is to auxiliary cutter 451,452 reciprocating motion between position SUL, SLL.Auxiliary cutter 451,452 is arranged to corresponding a plurality of groups, and the cutter in each group is unified reciprocating motion.

The cutter of each group 451,452 rises from position SLL to position SUL with identical speed and high unity together, but with different speed home position SLL.

When a plurality of cuttves 31 are positioned at its lowest order KLL when concentrate combining bar 11, cutter in 451 groups returns towards position SLL at faster speed than the cutter in 452 groups, and in second circulation, when the lowest order KLL that is positioned at them when a plurality of cuttves 32 combined bar 11 to concentrate, the cutter in 452 groups returned to position SLL at faster speed than the cutter in 451 groups.

Each comprehensive bar 11 comprises a backstop 420, and it engages with the cutter 451,452 that is mated work sideling.The top edge of cutter 451,452 is made into the convex surface 454 of inclination, and backstop 420 leans against on the convex surface 454 under normal position, and backstop 420 has a pair of support 422, and this extends two side directions of support 422 at block body, is used for contacting with the respective face 454 of adjacent cutter 451,452.Preferably support 422 also be tilt in the upward stroke of cutter 451,452, two cuttves rise with identical level.

Therefore, in such motion, combine bar 11 risings and do not do lateral deflection, because two supports 422 are held by two convex surfaces 454 of adjacent cutter 451,452.

Yet, when cutter 451,452 beginnings are when position SLL does drawback movement, two comprehensive bars 11 that are located at cutter 452 both sides all lateral tilt leave cutter 31, this is because the motion of the bottom of cutter 451 cuttves 452, thereby cause that backstop 420 slips over inclination convex surface 454 downwards, this can find out by the comprehensive bar 11b in Fig. 9.

Therefore, combine the non-pinning position that bar 11 moves to a side direction, the pinning structure 434 on this position pinning body 435 and cutter 31 separates a segment distance.Risen to its HUL position if combine bar 11, (as combining shown in the bar 11a among Fig. 9), it is held device 51 position IP acquisition therebetween.Thereby work as cutter 451,452 when its SLL position returns, backstop 420 motion disengaging faces 454 are combined bar 11 and are remained on its non-inflection point, pin body 435 in this position and are positioned on the mobile route of locking device 434.

Do not risen if combine bar 11, when its when its HLL position returns, its by to lateral deflection to non-pinnings position, it leaves an intersegmental crack with pinning structure 434 on this.

Best cutter 31, pinning structure 434 on 32 has mutual energy mutually to close the pinning support 438 of action with pinning body 435,439, this support is that the formation convex surface that tilts is used for pinning body 435 towards

cutter

31 or 32 deflections, thereby by

cutter

31,32 is entrained, and this is used for moving and pins position of body 435 arrival, and it is positioned at outside the mobile route of

adjacent cutter

31 or 32 in this position.

The 5th embodiment 500 has been described in Figure 10.

The 5th Jie embodiment 500 is except cutter 451,452 have upwards inclination convex surface 554 to be used for beyond pinning body 535 on the comprehensive bar 11 is meshed, other is local similar with the 4th embodiment 400, therefore, in the 5th embodiment 500, pin body 535 and also use, when pinning body 535 is positioned on the convex surface 554, combine the non-pinning of bar 11 lateral deflections to a position (as combining shown in the bar 11b among Figure 10) as backstop 20.

In addition, 451 groups of cuttves and 452 groups of cutter reciprocating motion phase differences are 180 °, thereby comprehensive bar 11 carries to its interposition IP by the cutter in 451 groups or by the cutter in the group 452 and moves.

When two groups of cuttves 451,452 all were positioned at their position, end SLL, the pinning body 535 of given comprehensive bar 11 sat on the convex surface 554 of two adjacent groups cutter 451,452, therefore, stayed the comprehensive bar 11 in non-inflection point place and was located in its shed open position, end.

Each cooperatively interacts deflection a pair of by they entrained comprehensive bars 11 to the cutter 451 that is close to, side direction arrives the non-pinning position of combining bar 11 away from the cutter 31 that cooperates with it, so that can not lock together between the locking device 534 that pins on body 535 and the cutter 31, each also has similar routing motion to the cutter 452 that is close to cutter 32.

Bar 11 is selected does ascending motion if combine, (as combining shown in the bar 11c among Figure 10), it is combined bar holding device 51 and is held in interposition IP, thereby when 451 declines, 535 supported 554 of the pinning bodies of selecteed comprehensive bar 11 put down, and combine bar 11 and move back to its non-deflection (pinning) position by the deflection of itself thus.Pinning body 535 is positioned on the mobile route that pins structure 534 now.

Just as among the embodiment 400, pin inclined plane 538 of body 535 tools, this face and the inclined seat 539 of the pinning structure 534 incompatible body 535 that will pin that matches moves towards

cutter

31 or 32, is pulled on the mobile route that leaves another one

cutter

31 or 32 against the comprehensive bar 11 of this action.

Another one is implemented 600 and is explained in 12c at Figure 11,12a.

Embodiment 600 and embodiment 500 are similar, and drive unit 50 comprises two cuttves 451,452, and they are at corresponding SUL, and the position differed 180 ° when the SLL displacement was moving.

As shown in Figure 11, combine bar 11 and be positioned at its shed open position, end and just preparing selectedly, in the embodiment shown in fig. 11, combine bar 11 and be held in end shed open by a backstop (not shown).

Each cutter 451,452 comprises that inclination convex surface 654 upwards is used for matching with the downward inclination convex surface 638 that pins body 635.

As shown in Figure 12 a, when cutter 452 position SUL on it rose, convex surface 654,638 engagements that cooperatively interact caused that a pair of comprehensive bar 11 is carried upwards to move towards its interposition IP.

Convex surface 654,638 causes and pins body 635 inwards towards cutter 452 motions, thereby will combine bar 11 and move to non-pinnings position, and in this position, comprehensive bar 11 can be moved to its IP position and not go to be meshed with cutter 32 that (Figure 12 a).

Do not need to rise to the top shed position if combine bar 11, then when cutter 452 drops to the next SLL, combine bar 11 and remain on non-pinning position.

Need to rise if combine bar 11, when cutter 452 descends, combine bar 11 and remain on the IP position by combining bar stop device 51.Shown in Figure 12 b.

Pin that body 635 has convex surface 639 upwards and the convex surface 640 of cutter 451,452 under having mutually.When pinning body 635 was carried by cutter 451,452, convex surface 639,640 descended with convenient cutter 451,452 directly relatively, and when comprehensive bar 11 was held in the IP position, comprehensive bar 11 was by convex surface 639,640 positive moving towards corresponding cutter 32.

Combine amount that bar is displaced sideways by relative convex surface 639,640 and enough move and combine bar 11 and arrive it and pin the position, thus the cutter 32 of rising on this can with pin body 635 pinnings and mesh together and will combine bar 11 and move to its top shed position.The initial pinning engagement that cutter 32 has been shown in Figure 12 b and has pinned body 635.

After beginning engagement, the relative cam surface that cooperatively interacts 539,638 will pin body 635 and move and make pinning body 635 leave adjacent cutter 31 1 segment distances (Figure 12 c) towards carrying cutter 32.

As shown in figure 11,

cutter

31,32 is preferably the compressed metal structure, and it has the identical two halves that link together; Pinning body 634 forms separately on half at each.

Preferably each

cutter

31,32 has one wide 651.Be designed to for wide 651 closely near the pinning body 635 that remains on upper comprehensive bar 11, this helps to guarantee an adjacent cutter 31 to upper KUL rising, 32 correct with pin body 635 engagements (promptly since the cutter that rises, combine that bar 11 can be blocked to pinning the extruding of body 635 deflect from non-pinning).

In Figure 11, combine bar 11 and remain on its shed open position, end by a baffle element (not shown), make when two cover cuttves 451,452 drop to their SUL position and pin body 635 and break away from engagement.

As the structure of a replacement, can be designed to work as cutter 451,452 when their low level SUL descends, stop a period of time, make that guaranteeing to combine bar 11 is pulled to its shed open position, end.

In this device, a cover cutter 451 of rising or 452 is collected from a

cover cutter

451 or 452 that descends and is combined bar 11.In this case, the comprehensive bar 11 that is positioned at shed open zone, the end is always entrained by one or another one

cutter

451 or 452, thereby being used for as shown in Figure 11 grip and combine the stop device of bar 11 in its shed open position, end and can not need, and embodiment 600 has guaranteed positive move of each comprehensive bar 11 between its pinning and non-pinning position.Thereby the main body of combining bar 11 needs not to be can elastic deflection, therefore preferably combines bar 11 and be made of plastics in embodiment 600.

Another one embodiment 700 has been described in Figure 13.Embodiment 700 is different on comprehensive bar 11, is provided with a member 740 on comprehensive bar 11, and it is used for cooperating running will combine bar 11 with cutter 451,452 and takes its IP position to, also is used for moving between its pinning and non-pinning and combines bar 11.Thereby, in embodiment 700, pin body 635 only with

cutter

31,32 interoperations, and not by 451,452 contacts of cutter.

As shown in figure 13, each comprehensive bar 11 has two convex body 740a, and 740b is used for respectively and cutter 451,452 interoperations, each convex body 740a, 740b have a downward inclination convex surface 742 to be used for matching with the inclination convex surface 743 that makes progress of contacted cutter 451,452.Convex surface 742,743 also is an inclined plane shape, is used for when convex surface 742,743 when being meshing with each other together, prevent they cutter 451,452 vertically on the side separately.

When cutter 451,452 rises to concentrate and carries when combining bar 11, the relative convex surface that cooperates with it 742,743 engagements cause and combine bar 11 to the biased commentaries on classics of non-pinning.

Each convex body 740 also comprise an inclined plane that makes progress 746 be used for cutter 451,452 on downward convex surface 747 be meshed.As combining among Figure 13 shown in the bar 11a, when convex body 740 fully seat on the cutter 451,452 time, convex surface 746,747th, directly vis-a-vis.

Combined bar holding device 51 and grip position IP therebetween if combine bar 11, convex surface 746, the 747 positive deflection that cooperatively interacts when corresponding cutter 451,452 descends is combined bar 11 and is pinned the position motion to it.

Preferably combine bar 11 and be made of plastics, convex body 740 best integral casts are on the main body of combining bar 11.

Another one embodiment 800 explains in Figure 14 a, b, c.

Embodiment 800 its comprehensive bars 11 are carried between its shed open position, end and the IP position by cutter 451,452 and move, and are identical with embodiment 500 in this; Be provided with convex surface on comprehensive bar 11, cutter 451,452 is used for the positive bar of will combining and deflects into from non-pinning position (combining a bar 11b Figure 14 a) and pin position (Figure 14 b combines bar 11c), and this puts identical with embodiment 600 and 700.

Therefore, identical with 700 with embodiment 500,600 respectively part is marked with identical label correspondingly respectively in Figure 14 a, b and c.

In embodiment 800, all have a plurality of protruding fingers 850 on each cutter 451,452, they are spaced apart along each cutter, have upwards inclination convex surface 554 on the protruding finger 850 and are used for being meshed with pinning body 535 on the comprehensive bar.Pinning body 553 has downward inclined plane 538 and is used for combining bar 11 by cutter 451,452 support, it was positioned at non-pinnings position (a) each comprehensive bar 11 was between a pair of adjacent protruding finger 850 for Figure 14, and the bossy body 811 that has lateral protrusions on the comprehensive bar 11 is positioned at the bottom of convex surface 838 this moment.

Bossy body 811 has inclination convex surface 812 upwards, and it cooperates with downward convex surface 814 on the protruding finger 850 and is used for when comprehensive bar 11 remains on the IP position the comprehensive bar 11 of deflection and arrives its non-pinning.Bar 11d is combined in Figure 14 c explanation one, and it has been selected to its top shed position motion.

Change bossy body 811 in the location of pinning under the body 535 to compile, can reduce the stroke of cutter 451,452, can just get the close more up stroke of cutter 451,452 down of down stroke of

upper slitter

31,32 by comprehensive bar.

Best, in Fig. 2 illustrated, the comprehensive bar 11 among all embodiment comprises that the comprehensive bar principal length direction in a plurality of edges separates the locking device 56 of arrangement, and this is adjacent row's the different height of comprehensive bar 11 acquisitions just, thereby can obtain the shed open that tilts, i.e. the yarn mouth splayed of warp-wise.More particularly, adjacent locking device 56 is spaced apart 6mm and arranges, and is the shed open of splaying step by step at interval so that can obtain one with 6 millimeters.

Each group cutter 31 or adjacent cutter of 32 are risen to different height, are convenient to obtain a shed open that tilts, and promptly the height that is risen at the cutter in front of every group of cutter is different with the height of the cutter of the cutter rising of back, and this has been known.

Thereby for a cutter in given one group of cutter, the row that needs to rise combines bar 11 and arrives a predetermined height, makes that pinning body 153 can lock together with predetermined locking device 56.

In actual applications, the position that physical location KUL is arrived in each stroke may change, because the comprehensive bar 11 required load of the varying number that is risen are different, this leans against under the maximum load when

cutter

31,32 be positioned at that it calculates upper KUL the time, guarantee to pin body 153 between adjacent upper and lower locking device 56, gap predetermined between them is a corresponding C ₁And C ₂, as shown in figure 15.

In typical case, locking device 56 is 6mm at interval, C ₁And C ₂Each has 1.5mm at least.

For the

cutter

31,32 in certain corresponding cutter group, the clearance C of 1.5mm at least ₁Or C ₂Do not obtain,, have a kind of danger promptly to combine bar 11 and pin and not reach with the disengaging of holding device 51 in this situation.If for example pin is first circulation than underload, and in second circulation, cutter but experiences a heavier load, rising that therefore can not be enough.

The present invention uses an independent holding device 51, wherein pins body 153 and need match with locking device 52 (to combining bar 11 selected its top shed positions that rise to), also matches with a predetermined locking device 56 to be used for thereon that the shed open position obtains to combine bar 11.

Thereby can not regulate the locked position that the height that pins body 153 guarantees the correct pinning of itself and locking device 56 and don't can influence locking device 52.

According to the present invention, preferably equip locking device 52 on two, their segment distances that is spaced, spacing between them is different from the spacing between the locking device 56, for example the spacing between the locking device 52 is 11/2 times of spacing between the locking device 56, promptly lift a special case, the spacing between the locking device 56 is 9mm.

This can make every row pin body 153 and be positioned two different height (a higher height and a lower height, they be separated by 9mm), at these two given rows' in height place pinning body 153 and one or another one locking device 52 interoperations.According to this method, pin body 153 and be used for obtaining to combine bar 11 in all row the insides at identical height.

If the height of each row's pinning body 153, makes clearance C because the last act degree difference of the

cutter

31,32 that is attached thereto ₁Or C ₂Same yardstick is impossible, and we may move and pin body 153 and (being called height) highly is set to other one highly setting (crying down highly) or vice versa from one so.There is a result to be about to pin body 153 like this and is positioned to a row and following a pair of pinning body 56 interoperations, be moved 9mm because pin body 153, and locking device 56 interval 6mm have obtained clearance C now ₁Or C ₂Identical yardstick.

It is contemplated that to have plural locking device, also can adopt different gaps, interval, for example Figure 16 a has showed a suitable comprehensive bar, and having gap that 5 locking devices 52 have and be the gap that 9mm and 10 locking devices 56 have is 12mm.
