Description

A kind of anti-leakage bag and preparation method thereof and Preparation equipment

Technical field

The present invention relates to a kind of anti-leakage bag and its mass production technical field, more particularly to a kind of waterproof bag And preparation method thereof and Preparation equipment.

Background technique

Known anti-leakage bag can be divided mainly into film plastic material bag, expected with PVC or press from both sides what screen cloth was obtained by high-frequency welding Plastic bag, coated knitted bag and by coating waterproof layer fabric suture and in bag inner seam lines cover heating sealing label item compound fabric Bag.Wherein, film plastic bag load-bearing capacity is poor, easily ruptures；Coated knitted bag feel, perception are bad；High-frequency welding plastic cement Not only feel is bad for bag, and it is higher to press from both sides the material costs such as screen cloth；The anti-leakage bag of fabric layer is packed into the inside generated after material Gravity mainly by fabric rather than sealant undertakes, therefore sealant can be made than relatively thin, can not only reduce material cost, but also can Mitigate overall weight and storage volume, and the tissue layer wrapped up in outside can also reduce the probability that its inner sealant layer is destroyed, and play Protective effect, therefore be widely applied on the product of shopping bag, waterproof bag, gift bag, packaging bag etc.But it is all at present This kind of product, in order to guarantee not leak, it is necessary to attach heat-sealing joint strip one by one on all sutures inside bag body；Not only hot pressing is pasted Item itself it is at high cost, and to cover and check one by one and extremely take a lot of work, inefficiency, effect is also bad, it is easy to let out Leak source and missing inspection.Therefore, not only production efficiency is low, work consuming, time-consuming, feed consumption (have to tissue layer as sanction by part sealant Cutting edge corner material is dropped), and manual operation is produced and comes that homogeneity of product is poor, unstable quality.

Therefore, how to provide one kind can be efficient by such anti-leakage bag, quick, inexpensive, high-quality on automatic production line The problem of manufacturing, be those skilled in the art's urgent need to resolve to amount.

Summary of the invention

In view of this, the present invention provides a kind of anti-leakage bags, comprising:

At least one layer of sealant, the sealant are located inside the anti-leakage bag, form whole quilts in addition to the position of opening portion Seal the bag body liner that will not be leaked；

At least one layer of tissue layer, the tissue layer are sheathed on the outer surface of the sealant, form bag set；

Bag body is collectively formed in the tissue layer and the sealant；

The sealant can integrally and fully be overturn the outside covered to the bag inside the tissue layer, and be turned over The tissue layer and the sealant after turning can keep smooth corrugationless (only in this way just to can guarantee after completing laminating step Bag body liner except opening portion position in addition to do not having any leakage point, otherwise fold, folding, dislocation etc. will lead to bag body liner Periphery cannot be bonded completely, left leakage point or easily burst apart a little)；

Preferably, application of anti-leakage layers or leakproof film are also coated on the outside of the tissue layer.

Further, the opening can also be by including heat-sealing, gluing, clamping, buckle, binding and/or convolution item One or more of modes be completely sealed.

The anti-leakage bag be include coated knitted bag, waterproof bag, storage pocket, shopping bag, take out bag, gift bag, give bag Inside one or more.

Preferably, the tissue layer is in addition to the ability including woven bag woven cloth, woven dacron, nylon cloth or calico Domain often with outside fabric, may also include because be limited to original high frequency or heat seal process cause in the art seldom apply or cannot answer Body-sensing/perception including fleece, single or double flannelette, ice silk scarf cloth, heat generating fiber cloth, extraordinary high strength fibre cloth is more It gets well, intensity is higher and/or the more silk fabrics of function, knitted fabric or braided fabric.For example, because easily due to fabric surface injustice Whole to lead to desoldering or owe weldering, high frequency or heat seal process originally can not fabric of the coating surface with villous or particle；And this hair In bright to tissue layer and laminating layer be bonded fastness require it is not high, so surface also can with the fabric of villous or particle Villus or particle-surface overturning are bonded (remarks: in order to avoid cumbersome, in relation to tissue layer and sealant in this specification in the past " fitting " include the various differences such as bonding, common compound, solvent-free compound, pressing, fusion, fused, lamination, patch mounting, overlay film Technique, referred to " fitting "), thus be made surface band villous or particle anti-leakage bag, this is original high frequency or heat seal work Skill at all can not accomplish.

For known anti-leakage bag when bearing excessive gravity, the position to burst occur is typically all in plastic cement ratio-frequency welding or thin The commissure that film hot weld is formed.Because sealant is than relatively thin, the binding strength of sealant weld seam be naturally far smaller than fabric or The tearing strength of suture.Sealant is arranged in tissue layer in order to guarantee that sealant is not torn for anti-leakage bag in the present invention Inside becomes bag body liner.In this way, the pulling force generated after being put into object will be transmitted in tissue layer rather than only by sealing Layer is resisting pulling force (at this point, sealant is mainly to seal, rather than resist the tangential pulling force of bag body；As long as tissue layer is not It is torn, sealing inner container would not rupture, and bag body can be used always).And since the weld seam in the present invention is using State can be pinched in the better tissue layer of tensile capacity, therefore these weld seams itself do not need to undertake excessive pull Power, and the weld seam of known anti-leakage bag wants 100% to undertake bag body tangentially to pull power, therefore the tear-proof of the anti-leakage bag in the present invention Intensity can be well very much.

It can get after possessing the above technical characteristic as the anti-leakage bag of representative using coated knitted bag, waterproof bag following many beneficial Effect:

1, the anti-leakage bag in the present invention produces in which may be implemented in automatic assembly line continuity from above, saving of work and time cost-saving, It is fairly obvious to improve production efficiency, advantage.

2, product of the present invention because can automated production, compared with artificial production, the consistency of product is good, and quality is stable, can It leans on, controllably.Traditional artificial operation High-frequency machine production anti-leakage bag quality depends on the experience and feel of worker, different workers it Between even same worker different time produces the contraposition of product, molten mass eats depth, melting time etc. can not Unanimously, stable product quality is poor, and is also less prone to check quality problems.And automatic assembly line production of the present invention can be kept away Exempt from the problem of these manual operations are difficult to avoid that, keep the consistency of product good, quality is stable, reliable, controllable.

3, anti-leakage bag of the present invention is after being packed into and holding storage, tangential pulling force in bag body will all by by being disposably made into or Tissue layer together is sewn by high-intensitive suture to bear and resist.This fabric construction being disposably made into is logical The seam fastness and tearing fastness for crossing the structure that high-intensitive suture is stitched together will be than by very thin sealant quilts The bonding intensity hotly joined together is eager to excel very much.This is obvious: if hotly joining the not tissue layer of sealant together Limit or pull, will be easily torn, tear, and by one weaving come tissue layer (no sewn seams) or pass through height Intensity suture is sewn the tensile strength of tissue layer seam together and binding strength will be than very thin together with hotly joining The sealant of one layer of bonding can be well very much.Therefore, it is made together with the sealant of the tissue layer of same density and same thickness The traditional anti-leakage bag obtained is compared with anti-leakage bag of the present invention, and the tearing toughness of anti-leakage bag of the present invention will be substantially better than traditional leakproof Bag, seam fastness and tearing fastness are all more many by force than traditional anti-leakage bag.

4, traditional anti-leakage bag cutting fracture is either sewed by the simple hot pick of very thin joint close sealant or lean against To joint close on again paste heat-sealing joint strip obtain leakproofness.These methods will be operated manually, poor reliability, be easy leakage； The high return of goods rate of traditional anti-leakage bag (especially sealing the waterproof bag of joint strip) is exactly because of this problem.And cutting in the present invention Complete, complete, the uniform knot of pressure such as laminating machine, patch mounting machine, sticking machine and/or laminating machine that severing mouth is all automated Fruit can make to whole process detection, not only high production efficiency, and bonding effect is good, covering is complete, is not easy to leak.

Preferably, the tissue layer in the present invention can select fleece, allow the anti-leakage bag and when human contact as Traditional flocking PVC air-bed is submissiveer like that, body-sensing and perception are more preferable.Fleece is since in its at least one side, there are fluffy thin Hair, can not grasp suitable pressing dynamics in " first paste and weld afterwards " moulding process of traditional such as high-frequency welding etc, therefore It is very difficult to apply on the compound anti-leakage bag of fabric；And moulding process is turned around as " first stitch and paste afterwards ", even dry in the present invention It is crisp that tissue layer is allowed to use under complete separable form with sealant, both very big dynamics pressings both can be used, can also do It is crisp both not press, therefore such cloth for possessing fluffy batt can be easily applied in product of the invention and will not Cause to owe weldering, desoldering and/or leakage problem.

Similarly, it is difficult that the various surface band hairs such as polar fleece, plush, suede nap, the snow Neil of anti-leakage bag are made very originally The method anti-leakage bag can also be made through the invention in the cloth to become mildewed to band.Thus obtained polar fleece anti-leakage bag warming effect More preferably, it is suitble to use when winter or low temperature；Not only warmth retention property is more preferable for thus obtained plush anti-leakage bag, and appearance More lovely, body-sensing is more preferable, more by the welcome of women and children.So, it can allow and generally be mainly used for market capacity originally Lesser outdoor sports or the waterproof bag waterborne when playing to storing, become the huge household items of market capacity, can be obvious Expand the sales volume of such product.

It is possible to further set bag body to, the canvas with sealant, folder screen cloth or woven bag etc. be wear-resisting and/or resistance to thorn Produce material.

Tissue layer used in the present invention may be either the pure fabric of absolutely not coating or associated layer, can also be to be beforehand with The fabric of coating or associated layer.There are pre- coating layer or the fabric of pre- foil layer itself more can very scrape, it is easier to handle；Cutting A possibility that fracture loose wire or scattered fibre, is lower；The strength of materials and load-bearing capacity can be more preferable.Moreover, if it is will be close in the present invention Sealing fits to pre- coating layer or again when pre- foil layer gets on, and has pre- coating layer or pre- foil layer as substrate, sealant Fitting fastness can be more preferable and/or be easier to be bonded；If in pre- coating layer or the reverse side of the pre- foil layer fitting present invention Sealant then can get the finished product that there are coating or film layer in two sides, and to adapt to, endurance is higher, outer surface is not hydrophilic, wear-resisting/resistance to Pierce the different beneficial effects such as intensity is more preferable.That is, the bag body section of finished product of the present invention by can be " tissue layer inside outside + sealant " is also possible to " precoated shet/pre- paste layer+tissue layer+sealant ", or even can also use MULTILAYER COMPOSITE, realizes " fabric Layer+sealant+tissue layer ", " precoated shet/pre- paste layer+tissue layer+sealant+tissue layer ", " tissue layer+sealant+tissue layer+ The sandwiches such as sealant+tissue layer " interlayer even multilayer sandwich structure.

The present invention also provides a kind of Preparation equipments of anti-leakage bag, include at least sewing device, laminating apparatus and cutting device.

The sewing device stitches out the multiple bags of sets for being orderly distributed in and linking into an integrated entity on fabric web and length direction and (removes Except opening portion) appearance profile that shakeouts.

It is described knit surely step be with including large circle machine, straight-bar machines, enlarged version glove knitter and/or footwear machine including one kind Or several looms will not be bonded bag set and weave the step come surely.

Sewing steps setting before cutting out step in advance, by sewing thread suture tissue layer be made be connected it is multiple It is not bonded bag set.

The sewing steps are in addition to including the main sewing steps to suture seam and/or seam tie rod between tissue layer Except, may also include to by non-seam tie rod be sewn to tissue layer get on pre- seam step and/or will include handle/convolution The whole seam step that the tissue layer that spare and accessory parts including item/pin thread/female thread is sewn to gets on.

By the sewing steps by fabric suture or by it is described knit surely step integrally knit surely acquisition be ordered in it is whole Multiple bags of sets being connected on a fabric web and length enter subsequent pre- sanction step, laminating step, eventually sanction for synchronous transport Device step and/or other various steps are handled.

The pre- step of cutting out is that the multiple bag set feedings that are not bonded that will be connected by conveying device cut out device in advance, pre- to cut out Device is close along the contour line outer rim for not being bonded bag set and is roughly parallel to the bag that is not bonded and covers tissue layer seam up and down Thread line or determine fabric upper and lower level handover seam, by other than temporary socket part be not bonded bag set cutting form pre- sanction bag body；At this point, pre- The outside for cutting out bag body is cut perforation hollow out grooving.

The laminating step is that pre- bag body of cutting out is conveyed into laminating apparatus；Sealant output device is by two layers of sealant simultaneously It is transported to the pre- two sides for cutting out bag body；Two layers of sealant is fitted to the pre- two sides for cutting out bag body to laminating apparatus respectively and indentation is engraved In empty grooving, so that all sites in all hollow out groovings are bonded to form fabric by this two layers of sealant No leakage point Fracture sealant obtains pre- out pocket body.

The middle sanction step be when needing to carry out multiple tracks fitting, by outside pre- out pocket body contour line grooving or other among Pattern needed for process is cut out.

The step of cutting out eventually is to be conveyed into edge sealing bag body to cut out device eventually, cuts out device eventually and leans on along edge sealing bag body contour line outer rim It is close and be roughly parallel to the suture sewing thread of tissue layer up and down or determine the handover of fabric upper and lower level be stitched to less 2 millimeters by fabric fracture Sealant is cut, and is obtained and is cut out bag body as finished product of the present invention or the whole of semi-finished product.

The purge step and/or removing the work positioning step be in the cutting step after, before laminating step, by cutting The chip and/or the end of a thread that step generates are removed before being sent into laminating step by them, to prevent them to be sandwiched into cutting Fracture sealant forms leakage point.

The removing the work positioning step is by being mounted on rotating direction and the exactly the opposite removing the work brush wheel of material conveying direction Removing the work brush that bag body is in close contact is cut out when cutting out bag body in advance and displacement, dislocation, fold occur and/or fold on roller and with pre-, it will be pre- It cuts out these folds of bag body or folding position brush is stroked and smoothed, and realize the pre- playback for cutting out bag body, position and divide.

The inside and outside overturning step routs up the tissue layer being located in semi-finished product sealant, including full-automatic inverting step, One or more of mechanical-assisted overturning step and/or artificial overturning step.

It is sutured by sewing steps or is orderly distributed in fabric web and length by knit that step integrally knits acquisition surely surely Multiple bags of sets being connected on direction are cut out step in advance and are cut out in the appearance profile in addition to opening portion after spreading out, cut-out portion Position is the hollow out grooving for having at least 2 mm in width, and cutting fracture leaves suture substantially in parallel or determines the friendship of fabric upper and lower level The bag that seam is formed covers at least 1 millimeter of contour line；Sealant is fitted in by bag by laminating step again and covers periphery, hollow out grooving And/or the two sides of bag set, it is with not staying any leakage point close paste that wherein bag, which covers the sealant of two sides at periphery and hollow out grooving, It closes, the fitting at bag set can be that part fitting is also whole fittings；Cutting out step by middle sanction step or eventually again will closely be pasted Hollow out grooving after conjunction cuts out (middle to cut out and cut out carry out simultaneously eventually, the end under the complete sanction of finally acquisition without any leakage point Cut out bag body)；It will be overturn inside and outside bag body by automatic or manual inside and outside overturning step again, obtain the finished product of anti-leakage bag of the present invention Or semi-finished product；The assembly of the spare and accessory parts including handle, convolution item, pin thread, female thread etc., matter are carried out by other processing steps again Amount inspection and/or final products packaging step etc..

The bag set can be to first pass through automatic assembly line directly to knit surely, can also be to first pass through automation sewing assembly line to incite somebody to action Non- cutting is obtained after mutual independent plural layer fabric or at least two-layer fabrics suture obtained by woven folding, is not turned over Turn and many with continuity (being connected) are not bonded bag set；The sealant and the tissue layer can in advance completely It is not bonded, can also not exclusively be bonded in advance, can also be bonded completely in advance.

The bag set is obtained if it is by knitting surely, then the sealant is not to be bonded completely in advance with the tissue layer , should first knit surely it is resulting connect together it is numerous be not bonded bags cover up and down two sides compound seal film and/or coating sealing Then glue is determined by the cutting device including laser, vibrating blade, dise knife, heating resistance wire in advance again with obtaining sealant Bag body profile, then will by the mode including joint strip, coating sealant, lamination, patch mounting, covering or compound seal film etc. All sealing finishes cutting fracture in addition to opening, then the bag body is cut completely, then is filled by the overturning on assembly line It sets or is manually totally turned over the bag body, refill handle or opening convolution item, it is anti-to can be obtained heretofore described one kind Leak-off pocket.

If the sealant is to be bonded completely in advance with the tissue layer, it should first pass through including quilter or sew with long stitches embroidery Including machine automation sewing assembly line first sew acquisition the numerous bags that are not bonded to connect together cover the long fabric warrping to be formed, so Bag body is determined by cutting device in advance again afterwards, then by including joint strip, lamination, overlay film, coating sealant or compound seal film By the cutting fracture in addition to opening, all sealing finishes mode inside, then the bag body is cut completely, then pass through flowing water The main bag body is manually totally turned over by inside and outside turnover device on line, is refilled handle and/or opening convolution item, be can be obtained A kind of heretofore described anti-leakage bag.Pass through again since the anti-leakage bag of fabric layer in existing well-known technique is entirely first bonded What high frequency, ultrasonic wave or heat-sealing were welded, therefore using technical solution described in this paragraph in raw material availability and technology maturation side Face has more advantage；Moreover, thickness is larger, the intensity of integral material because tissue layer has been bonded by sealant in advance It is more preferable with very degree of scraping, it is more convenient for producing；In addition, being produced using the ready-made fabric of fitting, do not need again complete with whole membrane material The whole pre- entire breadth for cutting out bag body of covering, as long as and overriding all groovings, sewing thread trace and pre- severing mouth and can be prepared by edge sealing Bag body (that is can replace width to seal for whole of even 2 meters more than 1 meter with generally there was only several centimetres wide of heat-sealing joint strip Film layer), it can substantially save cost.

There are also following several possible if the sealant is not bonded completely in advance with the tissue layer:

If the sealant and the tissue layer are not to be bonded but partially or completely pasted completely in advance after finished product is made Close, then should first including quilter or quilting embroidery machine including automation sewing assembly line first sew acquisition connect together it is numerous It is not bonded bag and covers the long fabric warrping to be formed, then lower surface coats sealant or compound seal film (sealing film on it again Can be bonded completely with tissue layer, also partially be bonded to alternative or jumping characteristic) to obtain sealant, then pass through cutting again and fills Set it is pre- determine bag set, then will be except opening by the mode including joint strip, coating sealant, overlay film or compound seal film etc. Except cutting fracture all sealing finishes, then bag set is cut completely, then pass through turnover device on assembly line or people The bag set is totally turned over by work, is refilled handle and/or opening convolution item, be can be obtained a kind of heretofore described leakproof Bag.

If the sealant is not to be bonded completely in advance with the tissue layer, finished product is made and is not also bonded completely, then answers The automation sewing assembly line including quilter or quilting embroidery machine first sew acquisition connect together numerous be not bonded bag The long fabric warrping formed is covered, then again by not being bonded bag set under cutting device cutting；In addition, by including that polybag produces Automation stream including line, latex balloon production line, aluminium film balloon production line, condom production line, buffering air column bag product line Waterline obtains bag body liner to use as sealant；It is not bonded bag by described by the turnover device on assembly line or manually again Set is totally turned over；Bag body liner is fully filled in by the automatic device on assembly line or manually again and is not pasted described in having overturn Bag set is closed, handle and/or opening convolution item is refilled, can be obtained a kind of heretofore described anti-leakage bag.

The bag set that is not bonded in described above is occurred with the long fabric warrping being connected.In fact, we can also be with Using device and method shown in the present invention, by one by one mutually it is independent be not attached to completely together be not bonded bag cover monomer into The operation such as row overlay film, lamination, compound (namely plus attached sealant and edge sealing) then will add the bag body after attached sealant and edge sealing Inside and outside overturning simultaneously carries out the operations appropriate such as other installation spare and accessory parts, can be obtained one of present invention anti-leakage bag.It should Although feeding and transhipment can reduce production efficiency based on manual operation to method between the various devices, product and system The protection scope of this patent is still fallen within as method.

Fig. 7 to Fig. 9 show waterproof bag used in a kind of outdoor activities of the invention (namely a kind of special shape Anti-leakage bag, only this bag be primarily not prevent the appearance storage on the inside of bag body from letting out, but mainly prevent extraneous rain or Water leaks into inside bag body the appearance storage gone to get wet in it when people carry out outdoor activities).

After user is put into appearance storage in bag, the convolution item 8 by collapsing and rolling tightly 7 two sides of opening is realized to opening 7 Sealing, then the pin thread 9 that the convolution item 8 rolled tightly bending makes to be connected to its both ends is inserted within female thread 10, realizes the sealing knot Structure will not scatter.

Embodiment 4

Figure 10 to Figure 21 is a kind of implementation for the anti-leakage bag manufacturing method and equipment that need to only carry out one of fitting in the present invention Example.

Shown in corresponding such as Figure 13 and Figure 14 each process, tissue layer 1A is knitted under on coiled at least two layers of material Nitride layer 1B (or folding same a roll of rig or repeatedly the bilayer or multilayer structure formed by modes such as foldings) is defeated Be sent at sewing device 21 and sewed, obtain it is inside and outside do not overturn, do not paste sealant also non-cutting but be all connected It is multiple not to be bonded bag set 39 (schematic perspective view of three of them row is as shown in Figure 10, the sectional view of two rows such as Figure 16 It is shown)；The cutting for not being bonded bag set 39 and continuously and being integrally sent into including cutting laser head and/or vibrating blade again Device 23 (pre- to cut out device 23A) is in (the stereochemical structure signal of three of them row of pre- sanction bag body 41 for state of shakeouing by precut into As shown in figure 11, the sectional view of two rows is as shown in figure 17 for figure), there is these pre- sanction bag bodies 41 required bag body to shakeout Body shape is only not yet got off by cutting at its opening 7 but is still connected at temporary socket part 38, is connected to these temporarily Pre- sanction bag body 41 at socket part 38 can stay side 36 to continue to be fed forward with what Integral synchronous moved；Make arrangement after due consideration generation in advance in order to prevent The end of a thread or chip 32 etc. influence subsequent fitting program and air-tightness, blow device 26 can be arranged after cutting out device 23A in advance, will be pre- Cut out the assembly line boards that blow off such as the end of a thread or the chip 32 that device 23A is generated；Meanwhile in order to avoid causing not and temporarily because of purging Socket part 38 connect pre- sanction bag body 41 middle rear end occur it is unnecessary displacement or dislocation etc., can also after blow device 26, One or multi-channel removing the work brush wheel roller 24 is set before laminating apparatus 22；It is provided with the direction of motion on removing the work brush wheel roller 24 and material is transported The exactly the opposite removing the work brush 25 in dynamic direction；Removing the work brush 25 ensures to be not in folding by the middle rear end of pre- sanction bag body 41 below Folded, fold, displacement or dislocation.Because cutting out bag body in advance in the front end in material movement direction is to be connected to the temporary socket part stayed on side 36 38, be not in folding, fold, displacement or dislocation in the state of staying side 36 to be tauted, middle rear end be only because it is pre- cut out after with Stay side 36 by independently separated part, two sides are easy to appear folding, fold, displacement or dislocation without the limitation for tightening power.It is wide Degree covers entire material gate width and the direction of motion and the exactly the opposite removing the work brush 25 in material movement direction constantly brush stroke smooth by Under it including it is pre- cut out bag body 41 including all materials surface, therefore it is pre- cut out any offset end generated in bag body 41, folding, Fold all by can all be returned by brush brush that these directions of motion are fixed its originally should position and divide state, can avoid folding Folded, fold, displacement or dislocation (fold and fold are brushed flat, be displaced or misplaced and brushed back and 25 direction of motion of removing the work brush stringent one The orientation of cause, hollow out grooving 31 and hollow out does not stay the side 36 to meet status requirement and uniform)；By one or multi-channel Removing the work brush 25 brushes flat the pre- sanction bag body 41 after smoothing out with the fingers just will be in the laminating apparatus 22 for staying side 36 equally continuously and to be integrally sent into； Upper sealant 2A and lower sealant 2B are fitted to the pre- sanction bag body 41, grooving 31 respectively or even stay side 36 by laminating apparatus 22 Upper and lower surface, obtaining edge sealing bag body 42, (schematic perspective view of three of them row is as shown in figure 12, the sectional view of two rows As shown in figure 19).Because grooving 31 is not have anything to stop or isolation between the upper and lower level of sealant, institute by the structure of hollow out When being bonded at grooving 31, upper sealant 2A and lower sealant 2B are to be directly attached to be formed together one layer of new sealing Layer (i.e. fabric fracture sealant 27), that is, the grooving 31 for passing through hollow out by upper sealant 2A and lower sealant 2B in Figure 36 are straight The fabric fracture sealant 27 formed after fitting is connect, realizes the sealing by fabric fracture sealant 27 to all pre- severing mouths 49. Edge sealing bag body 42 (namely unturned bag body liner 46) and grooving 31 after completing fitting equally continue integrally to be sent into Cutting out device 23B eventually becomes complete cutting portion 37 for the complete severing of temporary socket part 38.Meanwhile the fabric fracture sealant 27 in grooving 31 Also the two halves substantially to divide equally are split in grooving midline position, obtain the whole sanction bag body 43 got off by final cutting completely (eventually It cuts out all cutting fractures 49 other than opening of bag body 43 to be all completely sealed)；The bag body 43 of cutting out eventually passes through inside and outside overturning Device 28 will be overturn inside and outside it, and the bag body liner 46 that original sealant 2 can be exposed to outside is inverted into tissue layer 1 Portion.Through setting the inside and outside turnover device 28 preceding road and/or later process other automation or manual process will wrap The spare and accessory parts assembly for including handle 6, convolution item 8, pin thread 9, female thread 10 etc finishes, and finished product 45 can be obtained.

The above various processes and various devices can perfect cooperations, unified synchronous under computer control, it should be noted that The above-mentioned technology controlled using computer is quite mature at present, is specifically applied to not need to calculate when the present invention Big improvement in terms of machine program.Each road feeding mechanism (such as the surface advanced on board has certain adherency solid in fabric etc. The conveyer belt of capability), pretreatment process (such as non-seam tie rod 13 of the sewing Figure 35 into Figure 37 in advance), sewing device 21, It is pre- cut out device 23A, blow device 26, removing the work brush wheel roller 24, laminating apparatus 22, cut out eventually device 23B, inside and outside turnover device 28 and Other processing units 29 can realize the flow line production of mechanization, automation and NC postprocessing under the control of electronic equipment, very To in the case where budget allows also fully-automatic production can be realized by the Design of Production Line at " blackout factory ".It certainly, is reduction The total investment of machinery equipment and/or the cost effectiveness for considering full-automation and partial automation (process portion is manually), can also Process portion extraction is manually completed.

Accordingly with above-mentioned various processes:

Figure 15 shows the section D1-D2 in Figure 13 and Figure 14, and upper tissue layer 1A and lower tissue layer 1B is not yet stitched at this time Close, thus its section D1-D2 still non-tight suture but twice in discrete state are parallel or approximately parallel linear cut Face.

Figure 16 shows the section E1-E2 in Figure 13 and Figure 14.Upper tissue layer 1A and lower fabric at the section E1-E2 at this time Layer 1B have already passed through sewing device 21 be sewed line 15 be stitched into be not bonded bag set 39, so the upper tissue layer on the section E1-E2 1A and lower tissue layer 1B be closely stitched together by sewing thread 15 (remarks: in the present specification if not otherwise specified or It points out to separate between each adjacent tissue layer, between tissue layer and sealant, between sealant and bead layer, then they are answered This is the structure fitted closely together；It is intended merely to facilitate reader in this specification attached drawing to differentiate and facilitate explanation, just will These practical structures to fit together are shown in a manner of slightly separating.Similarly, the sewing thread 15 of this specification is also close Be bonded and lock its sutured fabric, we also for convenient for reader recognize just by sewing thread 15 with leave tissue layer have compared with It deliberately draws to grow the mode put apart from or by its end of a thread greatly to show).

Figure 17 is the F1-F2 schematic cross-section in Figure 13 and Figure 14.At this point, not being bonded bag set 39 at the section E1-E2 It is transported to pre- sanction device 23A and is done by it and cut (pre- to cut out) for the first time, become pre- sanction bag body 41.Pre- sanction bag after cutting out in advance Body 41 goes out the grooving 31 of hollow out, chip 32 by cutting and stays side 36.The pre- device 23A that cuts out can be laser cutting device, can also be The mechanical cutting device of oscillating knife etc.To be reduced or avoided by the issuable displacement of various pieces after cutting or dislocation, It is preferred that contactless laser cutting device；To guarantee that laser cutting device can be realized to edge sealing quickly, efficiently, in high quality The cutting of film layer, preferably sealant are to be easy to absorb the black or dark color of laser energy, rather than transparent, colourless or light.

Figure 18 show the G1-G2 schematic cross-section in Figure 13 and Figure 14, is the pre- sanction bag body 41 before will being bonded.It is pre- to cut out Chip 32 in bag body 41 clears out of grooving 31 by blow device, and grooving 31 is made to become engraved structure；Moreover, upper sealant The upper and lower sealant 2B that 2A has been covered on tissue layer 1A has been covered under lower tissue layer 1B.

Figure 19 show the H1-H2 schematic cross-section in Figure 13 and Figure 14, is the pre- sanction bag body 41 after being bonded, also It is edge sealing bag body 42.Upper figure in Figure 19 is deliberately drawn sealant and tissue layer with discrete state in order to facilitate understanding Schematic diagram, the following figure are the schematic diagram for being bonded the actual conditions as one layer according to sealant and tissue layer and having drawn.At this point, The upper and lower sealant 2B that upper sealant 2A has been fitted in tissue layer 1A has been fitted under lower tissue layer 1B；Upper sealing It is one layer that layer 2A and lower sealant 2B is bonded at the grooving 31 of hollow out, becomes fabric fracture sealant 27.In this stage, The cutting fracture 49 on 31 periphery of all groovings generated originally by hollow out has been sealed by fabric fracture sealant 27.Namely It says, comprehensively, has continuously been bonded by purged pre- pre- 49 upper and lower surface of severing mouth for cutting out bag body upper accordingly close Sealing 2A and lower sealant 2B.Upper tissue layer 1A and sewing thread 15 thereon are completely covered by the upper sealant 2A outside it Thus the fluid of the sealant side will not be allowed to leak into this by fabric fibre gap or pinprick hole after inside and outside overturning in future The other side of sealant is gone；Similarly, lower tissue layer 1B and sewing thread 15 thereon are also by the lower sealant 2B outside it It is completely covered thus the fluid of the sealant side will not be allowed to leak into other the one of the sealant after inside and outside overturning in future Side is gone；The pre- all cutting fractures 49 cut out around bag body are also sealed by fabric fracture sealant 27, thus in the future The inside and outside fluid for overturning side in back pkt. body will not be allowed to go by the original air gap leakage of cutting incision position to the external world.That is, this Embodiment has passed through fitting only once in this stage, just obtains bag body liner 46 required after overturning inside and outside in the future.

Figure 20 show the I1-I2 schematic cross-section in Figure 13 and Figure 14.Edge sealing bag body 42 in Figure 19 is transported to end Device 23B is cut out, cutting comes out completely and finally by it, obtains and cuts out bag body 43 eventually.Upper figure in Figure 20 is to understand for convenience The schematic diagram for deliberately drawing sealant and tissue layer with discrete state, the following figure are to be bonded into according to sealant and tissue layer The schematic diagram drawn for one layer of actual conditions.At this point, being conveyed through the edge sealing bag body 42 come from the section H1-H2 by eventually It cuts out device 23B to completely cut through all temporary socket parts 38 as complete cutting portion 37, corresponding bag body is also stayed from respective completely It is completely fallen off at side 36, becomes and cut out bag body 43 eventually.Bag body 43 is cut out eventually in addition to the severing notch of opening, and other all cuttings are disconnected Mouth 49 has been completely sealed.

Figure 21 is the section the F1-F2 front and back in Figure 13 and Figure 14 to the signal for simplifying and being exaggerated before and after the section H1-H2 Figure.The as space is limited limited chip 32 that cannot clearly draw, grooving can be not only more clearly visible that in Figure 14 by the figure 31 and fabric fracture sealant 27, and the generation process (as shown in the section F1-F2) of grooving 31 and chip 32 is also shown, cuts Bits 32 are bonded the process (as shown in the section H1-H2) of upper sealant 2A and cut out the formation of bag body 43 eventually after being removed by purging Journey.

Finally, cut out bag body 43 eventually is transported to inside and outside turnover device 28 and various other processing units 29 (including but not again It is limited to spare and accessory parts assembly device/process, passer/process, packing device/process etc.) it is handled, it is made into finished product simultaneously Packaging is standby to sell.

Inside and outside turnover device 28 in the present invention can be used that gloves factory is known by nearly half a century and to be widely used Mechanical gloves tipping arrangement: first by a set of rigid or semi-rigid column in simulation finger structure of unturned each bag body one In structure, then by these column structure tops to the end of each bag body until (each finger structure is in the inside of each bag body at this time), then The end of each bag body is withstood on the outside of bag body with another set of similar finger structure；Then with manpower, manipulator or other clampings Device catches opening, similar to catch waist belt to take off trousers or turn over chitling like that will opening from the end of one group of column structure draw to To the end of another group of column structure headed on until cannot draw again.Thereby realize inside and outside overturning.

In addition to the inside and outside turnover mechanism using above-mentioned two groups of columns or spreader formula, such as air blowing type can also be used, even It is that such as Fig. 2, Fig. 5 and manual mode shown in Fig. 8 realize overturning.Inside and outside air blowing type method for turning be with manpower, manipulator or its His clamping device catches opening 7, and first blowing toward the open end for not overturning bag body in narrow tunnel like structure heaves it, so It turns airflow direction again afterwards, blow in the end for heaving bag body and is simultaneously stopped the air blowing of open end, then bag body end is turning to It is moved under the action of air-flow afterwards along new airflow direction, realizes inside and outside overturning and towards exchange.

Method and apparatus shown in the present embodiment can be operated under the control of computer and other electronic equipments with high-speed synchronous； High production efficiency, human cost is low, stable product quality, consistent, adjustable, controllable, far wins existing one of process of a procedure The method and apparatus manually produced.

Embodiment 5

Figure 22 to Figure 23 show one of present invention and the directly sewing of bag body seam tie rod 14 is existed by sewing thread 15 It is formed together the embodiment of bag body subsidiary body.These seam tie rods can be used for fixing or connecting different bag bodies, sewing can be with Bear more heavy weight ribbon (such as jumbo bag structure), for perforating, beat button, threading and/or play role in decoration.

As shown in figure 22, on automatic assembly line board, by seam tie rod 14 (cloth) be folded in lower tissue layer 1B and Three is stitched together by automation sewing device by sewing thread 15 by the seam crossing between upper tissue layer 1A.Complete sewing Sealant is attached below the upper surface of upper tissue layer 1A and lower tissue layer 1B again can be obtained required sealing bag body (to avoid Picture is excessively cumbersome, and sealant is not shown in Figure 22；Referring specifically to above-mentioned manufacturing method and apparatus embodiments).Bag body will be sealed After inside and outside overturning, the structural relation explosive view of each component part is as shown in figure 23.Figure 23 is only to facilitate understanding and using The manifestation mode of explosive view, actually, upper tissue layer 1A, lower tissue layer 1B and seam tie rod 14 are to be sewed line 15 tightly It is stitched together, is to be close together mutually rather than be separated from each other as shown in explosive view each other.Sealant 2 And press the seam that tissue layer 1A, lower tissue layer 1B and seam tie rod 14 are formed.

Seam tie rod 14 is tightly sewn in tissue layer 1, not easily to fall off or scatter；Tissue layer 1 and seam tie rod 14 are total It will closely be covered by sealant 2 with the sewn seams formed, and be not easy gas leakage (if patch is anti-in advance before being sewn for tissue layer Leak film layer or leakproof coating, then the sealant 2 in Figure 23 can also be replaced with hot wind joint strip, function, principle and effect and Fitting or the sealant 2 not being bonded shown in Figure 23 have no significant difference).The seam tie rod production method is not limited in Three layers of suture way shown in this implementation, and also stitched again using the structures such as convex ribs and/or groove are first folded on long cloth It closes, is manufactured with a kind of without fracture, binding strength better way.Shape of product and application etc. should be specifically regarded flexibly to select With.

Particular, it is important that as shown in figure 23, after being packed into weight in bag body, if pullling inside bag body advocates to apply On tissue layer 1, seam, sewing thread 15 and/or seam tie rod 14, rather than on sealant 2.As long as therefore tissue layer 1, Seam, seam tie rod 14 and/or sewing thread 15 are not destroyed, and the sealant 2 being attached on the inside of tissue layer and seam will be by it The power being subject to is fully synchronized and is immediately conducted to tissue layer 1, will not generally be converted into and its own is wanted to bear and resist tangential Pulling force, tangential pulling force very little suffered by its own or almost without.Therefore, as long as tissue layer 1 and seam etc. are not being drawn tangentially It ruptures under the action of power, would not be ruptured without the sealant 2 for being subjected to excessive tangential pulling force against which.And tissue layer 1 can be held It is eager to excel by tangential pulling force ratio sealant 2 made of coating adhesive and/or plastic film with resistance very much, therefore such anti-leakage bag The load-bearing capacity of finished product can be improved very much.Especially belong to type disconnected from each other rather than fit type in tissue layer 1 and sealant 2 When, the power of pullling between two neighboring bag body is entirely applied on tissue layer 1 rather than on sealant 2.In this way It, all can be much smaller to pull dynamics and the impact force of sealant 2 when encountering fierce impact in the use process of anti-leakage bag.This Kind structure is particularly suitable for needing to bear extremely to hold the products such as leakproof jumbo bag of storage again.Therefore, the present invention in anti-leakage bag not only High production efficiency, production cost are low, and product quality is more preferable, can load capacity and impact resistance ability can significantly improve.

Known waterproof bag needs by a PVC folder screen cloth together procedure high-frequency welding or first passes through coating cloth one It is again that a sewing thread trace together genuine hot wind joint strip sealing, time-consuming and overall cost is high after sewing to one procedure of road. Waterproof bag in the present invention can disposably be worked it out by assembly line, and not only overall cost can be greatly reduced, Er Qiesheng Production efficiency, production capacity, yield and quality stability can get and is greatly improved.

As shown in figure 47, outside in the present invention including anti-leakage bag finished product after overturning, with known " sewing+heat-sealing joint strip " As the opening of type, the support top gap 47 of engagement corner portions is easy to appear at opening position.For example, by upper sealant 2A with turn over Transfer poststack on the sealant that seam crossing extends extended layer 2A2 formed intermembrane space 47A, by lower sealant 2B and overturning After folding under the sealant that seam crossing extends extended layer 2B2 formed intermembrane space 47A, cut fracture sealant 27 package Extended layer 1B2 (i.e. the leftover of bolt of cloth or selvedge) also has certain thickness under extended layer 1A2 and fabric on the fabric that seam crossing extends, Therefore after being bonded fracture sealant 27, when the leftover of bolt of cloth or selvedge thickness suddenly become zero because of cutting fracture, thickness difference can be generated Gap 47B.These spaces are at convolution closing opening 7, if not enough (e.g., the lesser women and children of physical strength make the dynamics used Used time) or the upper tissue layer 1A or lower tissue layer 1B thicker (e.g., cotton flannel) that use, the intracapsular gas after convolution is just Leakage in the minim channel formed by these support top gaps 47 is easy to enter.Although leakage meeting very little, for product It is that be avoided the problem that as far as possible for design.Its solution has very much, such as: it is use up when gluing, sealing layer Amount improve fitting roller pressing dynamics with decrease or even eliminate thickness difference gap 47B, using it is thicker and be pressurized after deformation quantity compared with Big upper sealant 2A and/or lower sealant 2B, the position with support top gap 47 add it is thicker and be pressurized after deformation quantity compared with (such scheme is in Chinese Patent Application No. 20181023922.5 and Chinese Patent Application No. for big sealant etc. Have in 20182034935.8 and be very described in detail and illustrate).

In the present embodiment, it will can be provided in addition the characteristics of automatic assembly line produces using the product in the present invention A solution.

As shown in figure 48, cross can be gone out in the appropriate location cutting of tissue layer 1 according to the size of final products and opening 7 To joint-cutting 51.The effect of lower tissue layer 1B after lateral joint-cutting 51 is arranged is as shown in figure 49, and upward convolution can be formed at joint-cutting 51 Lower tissue layer fin 1B3；The effect of upper tissue layer 1A after lateral joint-cutting 51 is arranged is as shown in figure 50, can shape at joint-cutting 51 At the upper tissue layer fin 1A3 of downward convolution.The upper tissue layer fin 1A3 of these convolutions or lower tissue layer fin 1B3 of convolution The normal methods such as air-flow blows folding, mechanical arm clamps or absorption is bent can be cooperated real by positioning mechanism on automatic assembly line It is existing.

Then again as shown in figure 51, the upper tissue layer 1A after lateral joint-cutting and folded over tab and lower tissue layer 1B phase will be set (joint-cutting by continuity, is periodically not yet arranged to make-up by the long cloth of final cutting on assembly line and bends the wing It is buckled togather after piece) after, then as shown in figure 52 finished upper tissue layer 1A and lower tissue layer 1B suture by sewing thread 15； Then it is bonded upper sealant 2A and lower sealant 2B accordingly on the outside of upper tissue layer 1A and lower tissue layer 1B as shown in figure 53 again； Installing, various accessory accessories are front/rear, then inside and outside overturning obtains the present embodiment opening 7 as shown in figure 50.

It is final as shown in figure 54, tissue layer fin 1A3 on the seam extension at 7 inseam of opening in the present embodiment, Lower tissue layer fin 1B3 has been turned to except opening 7, rather than is clamped within fabric fracture sealant 27.Finally exist The fabric fracture sealant 27 obtained at opening inseam is very thin film layer, and without tissue layer.In this way in opening inseam Locating the support top gap 47 formed is just only intermembrane space 47A, and the thickness difference gap 47B in originally Figure 47 is just not present.By This obtains a possibility that gap forms connectivity tiny leakage passage at fabric seam folding after by convolution at open seam just It is greatly diminished or avoids.And fabric fracture sealant 27 is that upper sealant 2A and lower sealant 2B presses together gained, Therefore its thickness and deformation quantity after being pressurized are inherently bigger, by intermembrane space 47A after convolution there are a possibility that will be by Greatly reduce or even is eliminated.

Tissue layer fin 1A3, lower tissue layer fin 1B3 have been turned to opening on seam extension at opening inseam Except after, can also be used as the purpose of sewing on handle 6 or fixed convolution item 8.

It, can as fabric fracture sealant 27 in the support top gap or thickness difference gap that its own is likely to form at cutting To give using the inclination angle type doubling roller 22D or inclination angle type laminating wheel 22F for having certain inclination angle theta as shown in Figure 62 or Figure 64 It eliminates to the greatest extent.That is, passing through these inclination angles type doubling roller 22D or inclination angle type laminating wheel 22F for fabric fracture sealant 27 The cutting fracture of itself be pressed on section thickness gradually from large to small, until final thickness becomes zero wedge shape or sharp cone distal Structure.Fabric fracture sealant 27 with this class formation can be pressed during convolution upper sealant 2A thereon and under it is close Sealing 2B exists in a manner of no any gap, eliminates fabric fracture sealant 27 and is likely to form at cutting at its own Support top gap or thickness difference gap, further avoid the possibility of leakage.

It preferably, can also will be various including open seam cutting fracture 49 and open seam fabric fracture sealant 27 Notch or fractured edge contour line are made into oblique line, curve and non-rectilinear, then these oblique lines, shaped form notch and/or fracture are in quilt It will not be squeezed by the sealant of same position after convolution, squeezed by the sealant of different location, therefore it may The support top gap of formation and intermembrane space will be dispersed on the different location of convolution item and be cut off by convolution corner, no Through leakage/leakage passage is easily formed, can be further improved final products anti-leak and/or leakage performance.

Bag body tissue layer in previous embodiment is to suture plane by sewing thread to get.In fact, sewing is not The necessary process of the present invention can also pass through other non-sewing processes acquisitions such as directly knitting surely in such as the present embodiment.

Can be used large circle machine, the glove knitter of enlarged version, enlarged version footwear machine etc. it is similar determine to knit device, directly weave It is not bonded bag set, is not then bonded bag at these again and covers upper gluing, sealing layer, then outer overturning front and back assembles other zero inside Finished product is made in part or accessory, finally can be obtained anti-leakage bag of the present invention.Above method is by fixed except bag set is not bonded It knits as obtained by sewing, other steps are substantially the same as in the previous example.

It certainly, also not necessarily must gluing, sealing layer after knitting acquisition surely and not being bonded bag set；It can also bag body liner and fabric Layer is not bonded, but after respectively independently producing, then by bag body liner made from independence fill in after inside and outside overturning determine to knit obtained by It is not bonded within bag set, obtains finished product.

Because anti-leakage bag opening presence, be particularly like in structure gloves or socks when being worn to protrude into hand or The gloves of foot/socks opening, therefore can be relatively easily with the glove knitting machine of enlarged version, the footwear machine or large circle machine of enlarged version Etc. equipment weave.It is many only to weave becoming large-sized for product for the two principle and indistinction.

It is integrally woven surely by equipment such as the glove knitting machine of enlarged version, the footwear machine of enlarged version or large circle machines not to be bonded bag No cutting fracture is put on also without determining interwoven layers of fabric, and fabric fibre and yarn are all that continuously, there is no a large amount of cuttings The process of fabric fibre and yarn, thus its finished product be resistant to the ability of tangential pulling force will be obviously than there are the bag body of sewn seams It is much strong；Load-bearing, impact resistance and the durable level of the anti-leakage bag finally obtained will be apparently higher than the bag body of sewn seams.

It is such knit surely bag body even can not have to automation or assembly line be produced, but manually will one by one by It is not bonded bag set feeding sealant laminating apparatus, another one ground obtains edge sealing bag body and carries out subsequent processing.Such producer Although method efficiency can be lower compared with automatic assembly line, the skilled sewer in traditional sewing tech is not needed due to it The joint strip work high with skill requirement, labour cost still can be much lower, final product quality also can it is more consistent, stabilize and increase.

Sewing device described in the above each suture embodiment can be include single head single-needle quilter, it is single-head multi-needle quilter, more Head single-needle quilter, multi-end multi-needle quilter, single head single needle quilting embroidery machine, single head multi-needle long-stitch embroidering machine, bull single needle quilting embroidery machine, bull One of sewing device including multi-needle long-stitch embroidering machine, embroidery machine etc. is a variety of.

The various processes such as the above cutting (including cut out and/or cut out in advance eventually), purging, fitting, edge sealing can only be not merely arranged At a procedure, but can depending on the needs specifically produced, be configured with multiple tracks cutting (including cut out in advance, it is middle sanction and/or eventually cut out), The repeatedly assembly line of the processes such as fitting, multiple purging, multiple removing the work, multiple edge sealing.

Moreover, some processes can also suitably exchange tandem in the case where not influencing production and quality.For example, Not influencing production and in the case where quality, by before the setting of part spare and accessory parts assembly device inside outer turnover device still it Afterwards, it has no too many difference, but should be to facilitate inside and outside turnover device crawl, convey and overturn and subsequent assemble etc. It is quasi-.That is, when making the anti-leakage bag in the present invention, sewing, cutting cut the different works such as slot, inside and outside overturning, dress spare and accessory parts Sequence can be by " stitch, cut, paste, turn over, fill ", " stitch, paste, cut, fill, turn over ", " paste, cut, turn over, stitch, fill ", " cut, paste, turn over, stitch, fill " etc. Different order selects most suitable scheme.

Certainly, consider production line cost and investment return than it is optimal in the case where, in addition to a few road core process are best Except automatic assembly line production, other processes are also possible to interrupted or manual operation.For example, last spare and accessory parts Assembly is often nonstandardized technique technique and the differences such as different product spare and accessory parts quantity, material, size and shape are huge.In this feelings Under condition, such as to realize that full-automatic flow line production can all adapt to these huge differences, the production equipment of investment at Compared with the labour cost that can be saved, possible input and output cost effectiveness is not high, therefore can also pass through artificial rather than machine for this Device executes such process portion.

The cutting device, in advance sanction device, sanction device etc. both can choose the contactless cutting device such as laser eventually, Traditional Mechanical Contact cutting modes such as vibrating blade, dise knife, heating resistance wire even die-cutting machine may be selected.Do not considering to flow In the case where waterline cost, pay the utmost attention to using laser cutting mode；Because laser cutting mode is cutting for on-mechanical contact Sanction mode can be remained unchanged by the portion that sanction is got off, be conducive to when no extraneous undue oscillation and wind Thereafter the positioning, contraposition etc. of various processes.

Carry out the processes such as cutting in order to be more accurate, also may be used on assembly line setting camera shooting projection positioning device, Witness marker is preprinted in fabric surface or contour line carries out the various very mature positioning and/or alignment method such as identifying.When So, the line of different colours and color difference, the contrast difference of cloth etc. can also be utilized for machine recognition or positioning；Especially use When the big line of color difference makees bag body suture, machine recognition, positioning and contraposition will be particularly easy to and precisely, it is corresponding it is pre- cut out, Pressing, middle sanction, whole sanction, grooving cutting is equidistant or width control can be more accurate.

In addition, in order to reduce the occurrence probability of the unfavorable phenomenon such as displacement, dislocation, folding or fold, in addition to various intelligence are arranged It can identify, outside positioning or alignment system, sewing device, laminating apparatus, removing the work brush wheel roller, purging dress in the various embodiments described above Set, cutting device etc. can also be set to be very close to each other with it is compact, transport distance of the material in the procedure of front and back is very It is short, even close to not having so that do not have enough time also being subjected to displacement after the material on board or wheel roller group is handled by preceding working procedure, Dislocation, folding or fold etc. are just bonded and/or cutting finishes.

For convenience of understanding, the working face of various equipment is in setting same level, but in reality in previous embodiment In production, in order to save the volume and cost of machinery equipment, each working face is often to be staggered.It is general as shown in Figure 66, lead to It crosses 52 different spatial of registration roller combination (wheel roller group) and nests together a variety of different working faces are compact, make machinery equipment Volume and/or occupied area is smaller, equipment feed consumption is less, cost is lower, etc..
