Abstract
The present invention discusses a kind of tampon 10, on the columnar circumferential surface of being essentially of tampon, adopts hot pressed way, but the fastening thermoplastic of a kind of sepage.But but putting into the situation that still is in the thermoplastic that does not have sepage on the cheese necking down 10b that holds 10a with the taking-up end 10c of tampon 10.The sepage material is fastened on the tampon 10 absorbent material outer surfaces, but guarantees that the capillary substantially height water absorbing properties of non-textile fiber material constantly reaches its surface through the thermoplastic of sepage.In addition, but the material of sepage prevents coming off of fiber, and makes and tampon put into and take out the abdominal cavity and become and be more prone to.
Description
The invention relates to a kind of health care of women tampon, but it being by the non-textile strip of one section length-specific and a kind of sepage, is that the band section (it is fixed on an end of non-textile strip) of thermoplastic is formed to small part.Non-textile strip is made up of natural and/or the irregular winding of staple fibre, and the length of width and tampon about equally.Non-textile strip section is essentially the coiling of self and load onto take out knot after, just formed the blank of tampon; The band section after the circumference winding of tampon blank, again through compression radially, has just been formed the final form of tampon.
The tampon of the above-mentioned type and the machine of producing this tampon be by for example, and the 915th, No. 382,1,491, No. 162,1,491, No. 200,1,938, No. 942 and 2,135, No. 495 German patent specification are introduced respectively.Facts have proved: this class tampon performance can be superior, because it not only has very high water absorbing capacity, and when tampon is drenched by liquid, also has splendid dilatancy, thereby user got safe and reliable menstruation protection.In addition, this class tampon also has technical superior part, and that is easy to carry out large-scale production exactly, and steady quality.
The 635th, No. 508 swiss patent specification has been introduced a kind of tampon, this health care of women tampon by reel with compression after non-textile strip constitute, tampon has been loaded onto one with a kind of specific process and has been taken out knot, but because requiring user to use, this tampon has some specific physiology prerequisite, otherwise, putting into, during particularly from intraperitoneal taking-up tampon, can not prevent coming off of fiber fully.Around this tampon is one deck wrappage, wrappage by, such as: non-textile material is made, when making tampon, (it is much wideer than non-textile strip section that the wrappage part is generally all done), wrappage partly is fastened on the end of the non-textile strip that is made of absorbing material.After non-textile strip section winds up, together with forming the parcel section, stretch out from the two ends of tampon respectively on the limit of wrappage, like this, before the tampon blank is suppressed, just must be first these columnar wrappage frontier fortresses be gone in the centre joint between the layers of absorbent material of tampon blank.The result, except wrappage be fixed on the non-textile strip that part of, it is very loose that tampon is reeled, have and cause the danger that forms the slit between wrappage and the tampon, when using such tampon, since the capillarity (this is important to absorption) of fibroid tampon material can not continuous effective pass the skin that wrapper arrives lapping, the fast Absorption effect of tampon is just hindered.The result has damaged most important water absorbing capacity of tampon and rapid expanding, and this most important parts in tampon defencive function just.In addition, the wrapper limit of stretching out tampon material both sides as the sleeve also makes troubles to production, because the end face of hemostasis blank must be filled in these limits, carries out and this process is difficult at least comparatively speaking, and can reduce speed of production, increase production cost.
Patent specification the 3rd, 523 has been introduced a kind of medical or tampon that surgery is used for No. 535.Manufacture process is such: successive at one, but on the top margin of the non-textile material band of the thermoplasticity of sepage, the spray layer of the wood pulp cellulose of coating last layer 6-8 millimeters thick, forming tool of reuse stretches this band that is made of two layers of material, in this forming tool, under the effect of heat and pressure, the longitudinal edge of the band that will be made of two layers of material overlaps each other at the top and connects, form a cylinder, then the cylindrical shape material of this longitudinal extension is cut into required tampon section.This tampon is not suitable for the usefulness as health care of women, in actual use success.Except other reason, also because this tampon can not expand.Because connecing in the mould before non-textile material end, slight radially extrusion takes place in wood pulp cellulose, and the non-textile material of topped circumferencial direction at the cylindrical shape fiber is welded together mutually.Wood pulp cellulose is not have elasticly basically, and it can not give tampon stability or bending strength, and this is in that tampon is easily put into intraperitoneal is needed.And when this tampon was drenched, wood pulp cellulose can disintegrate, so this hemostatic body also is unsettled.
The objective of the invention is above-mentioned tampon is improved.Novel tampon will have the fibre fluff of preventing and come off, and surface texture is easy to successfully put into characteristics such as taking-up abdominal cavity, simultaneously, does not influence the absorbability of tampon, water absorption and important dilatancy.And the tampon of special type also is easy on a large scale, and the ground of guaranteeing the quality produces economically.
Owing to adopt the way of heat sealing, but the thermoplasticity band of sepage is bonded in non-textile strip the preceding paragraph and tampon blank circumferential length distance about equally is last, outer section of band, promptly exceed that part of of non-textile strip section end, welding is in the outer end of sealing-in that part of band section on non-textile strip section, thereby reached purpose of the present invention.Its advantage is that the non-textile strip of ratio that band does is narrow, makes to put into the non-textile strip of end and can make the necking down shape, and can fast Absorption liquid.Preferably a kind of biconstitutent fibre of the non-textile material of band, the outer field fusing point of this fiber is lower than the core of fiber, therefore under the high-speed case of large-scale production, can guarantee that sealing-in is reliable between the band Duan Yufei textile strip, also can guarantee the structure of non-textile strip.
Manufacturing process below adopting can be produced tampon of the present invention easily;
But with one section sepage, the band sealing-in of thermoplastic is in the outside of non-textile strip rear end, the width of non-textile strip and the length of tampon are about equally, on non-textile strip, put into one and take out knot, self just forms a tampon blank after reeling, after treating that band is bonded on the tampon blank circumference, again the tampon blank is compressed, must the tampon of final form.Be tampon produced according to the invention, invented a kind of manufacturing process, make the sealing-in of thermoplasticity band on non-textile strip the preceding paragraph and distance that the tampon circumferential length equates substantially, after non-textile strip self is reeled formation tampon blank, the last sealed end that exceeds non-textile strip section, through the hot pressing welding on the band section.
A kind of equipment of making tampon according to the present invention is made up of with the tactic device of processing technology direction following these substantially:
1. non-textile strip support roller that is used for continuous natural fiber and/or staple fibre.
2. non-textile strip puncture device.
3. non-textile strip transporter.
4. continuous cutter sweep of the non-textile strip of cutting.
5. one is taken out connection and the knotting device of tying.
6. winding station that non-textile strip is wound into the tampon blank.
7. transmit and the cutting tonger: this device can move back and forth on the transmission plane of non-textile strip, downcuts one section non-textile strip section at every turn.
8. the tampon blank is sent to the device of compressor, in compressor, the tampon blank forms final tampon form after being subjected to fully radial compression.
9. tampon is put into the forming device of end.
The characteristics of the equipment of non-thromboembolism produced according to the invention are as follows:
A support roller that is used for continuous non-textile strip is housed, and the support roller back is a cutting bed, and cutting bed cuts into successive non-textile strip the section of length-specific basically.After cutter sweep, a band is housed cuts apart and transporter, be a sealing-in platform after this, the thermoplasticity band is sealed to the outside of non-weaving tape thing.The downstream of sealing-in platform is the transporter that a non-textile strip that will be stained with the band section is sent to cutter sweep continuously.Here, same heatable welding of winding station and flattening device connection connect, and this device is used to compress band section end, and an end that at will exceeds non-textile strip section and bar section rear end is crimped on the band section that is bonded on the non-textile strip.
, between them, can not produce the slit because but the thermoplastic of sepage is fastened on the non-textile strip.Simultaneously, the tampon of pressurized shaping has also all kept water absorbing force and expansion characteristics.Thermoplastic around the tampon has also significantly reduced the resistance when tampon is put into the abdominal cavity, so it is more comfortable and convenient that user can be felt, in addition, does not also cause the possibility of fibre shedding fully when putting into and take out tampon.Good bond between the thermoplasticity band Duan Yufei textile strip has guaranteed that the profile perfection of tampon is smooth, has increased the comfort of user when putting into tampon.Also find simultaneously,, can not only guarantee the bonding reliable of band section and textile strip, also kept the structure of band section even under very high speed of production.The result, after non-textile strip section is reeled formation tampon blank, non-textile strip section still is bonded on the non-textile strip securely, even when having centrifugal action on it, particularly when the free end of centrifugal action in its not sealing-in, situation also is that so this point does not reckon with.Because in conjunction with firm, when the tampon that will be filled abdomen liquid with the taking-up knot took out from the abdominal cavity once more, thermoplastic had been preserved its slick surface between the band Duan Yufei textile strip.Because the effect of band section makes with the friction in abdominal cavity and lowers, and helps to make expansible tampon fibre structure to keep and the roughly similar shape of tampon blank.
The typical case establishes sketch map by reference, below the present invention is introduced in more detail;
In following figure:
Fig. 1 to Fig. 6 represents the processing technique step of tampon produced according to the invention.
Fig. 7 has introduced a kind of equipment of tampon produced according to the invention with a width of cloth sketch.
Fig. 8 has introduced the equipment among the Fig. 7 after a kind of improve.
Fig. 9 has introduced and has transmitted the plane graph that is in the tight position of pincers with the cutting tonger.
What Fig. 6 represented is a health care of women tampon 10, it comprises the non-textile strip 30(of light Fig. 1 of a length-specific, 2,7,8) section 11(obviously illustrates in Fig. 3), it is made up of the natural and/or artificial dimension of irregular winding non-textile strip 30, and the length of width and tampon 10 about equally.This non-textile strip section 11 promptly constitutes tampon blank 12 along one with the horizontal lay of its longitudinally after the axle self of its outside, lengthwise center is reeled, at this simultaneously, the tampon blank is furnished with one and takes out knot 13.Just made the tampon 10 of final form after tampon blank 12 compressed fully with the direction of wireline reel.Because working pressure, indent is distributing on the angle of circumference that equates on the tampon 10.The end 10a that puts into of tampon 10 is designed to a curved dome-shaped necking down 10b.
According to the present invention, adopt hot pressed way, but by sepage, band section 15 sealing-ins that thermoplastic constitutes are on that part of non-textile strip section 11 of the periphery that constitutes tampon 10, the band section is done slightly longlyer than the circumference of tampon blank 12.
Fig. 2 to Fig. 4 represents that thermoplasticity band section 15 is bonded on the non-textile strip 30 tightly by melting welding face 79, and weld seam is parallel to each other at interval, acutangulates with the longitudinally of non-textile strip.Distance between each melting welding face is the same with distance between every capable melting welding face.But the thermoplastic of the sepage of band section 15 is attached on the non-textile strip material tightly.After so just guaranteeing that liquid runs into band 15 on the tampon periphery, the capillarity of the fibrous material of non-textile strip section 11 that can be below band is sucked into the inside of tampon at once.
The outer end 15a of band section 15 exceeds the outer end 11a of non-textile strip section 11, and by using heat and pressure, this outer end 15a is fused the outside in that part of band section 15 of sealing-in on non-textile strip section 11.
Significantly, but the band section 15 of the thermoplastic of sepage is narrower than non-textile strip section 11, but the longitudinal edge 11b of it and non-textile strip section 11, one side promptly constitute the aliging of taking-up end 10c of tampon 10.Non-textile strip section 11 constitutes tampons 10 and puts into the longitudinal edge 11c of end 10a and exceed and be attached thereto, but the length that limit 15c one segment distance of the thermoplasticity band section 15 of sepage, the length of this segment distance and tampon 10 are put into the cheese necking down of end on the 10a about equally.But thermoplastic non-textile fiber material accounts for major part at least in the formation of sepage band, and the thermoplasticity band fiber of handy a kind of pair of composition is made; Core that these two kinds of compositions for example can be polyester and polyethylene from high pressure process top layer part are if the fusing point of polyethylene from high pressure process is lower than wing ester just better.Because the free outer end 15a of thermoplasticity band section 15 is that welding is in the outside that is bonded in that section band 15 on the non-textile strip section 11, band section 15 forms one deck covering on tampon blank 12 circumference, it is to be connected tightly on the tampon blank, and its external diameter equates with the external diameter of tampon blank 12.Because this layer covering is that alkane is connected on the fibrous material of non-textile strip 30 tightly, guaranteed that fibrous material can see through the height capillarity of covering, (for example German patent specification the 1st through a compressor that the star pawl is housed for this fibrous material, 491, described in No. 161) tampon 10 made after the compacting, except that possessing the suction and absorbability identical, also have fiber and do not come off and keep the constant characteristics of helical shape with the tampon that does not have covering.
The production technology of above-mentioned tampon is made up of following step, below by consulting Fig. 1 to Fig. 6 these steps is introduced.
According to Fig. 1, the non-textile strip of light continuously transmits.Non-textile strip be by irregular jar around natural and/or staple fibre constitute, the length of its width and tampon 10 is similar.Non-textile strip 30 is by a so-called weakened points 31, and for to stamp the hole between the tampon 10 necessary length sections 11 weakened in order to make, the hole of getting is with nonwoven vertically crossing at cutting edge of a knife or a sword one.Simultaneously, non-textile strip is strained, it is weakened.Like this, in tension district or weakened points 31 places attenuation has just appearred, or reduced cross-sectional area, but do not cut off textile strip 30.Non-textile strip constantly moves towards the direction of arrow X indication.Almost simultaneously, constantly carry the band 32 of the non-textile material of thermoplasticity sepage to be cut off, cut into band section 15 at every turn, its length surpasses the circumference 1 of the tampon blank 12 shown in Fig. 5.Then, but in the directions X back of non-textile strip 30 these piece sepage thermoplasticity band fragment 15 sealing-ins on the outer periphery of non-textile strip 30, place it in weakened points 31 before.Heating and pressurization on parallel melting welding face 79 simultaneously, this face 79 and the axial direction of non-textile strip 30 be relative one-tenth crosswise to.See Fig. 3 and band section 15 is exactly its outer end 15a(on the top of non-textile strip 30), to the direction back, this band section 15 is freely to extend at the X of non-textile strip 30, that is to say does not have sealing-in, not on weakened points 31 limits of non-textile strip 30.Then, non-textile strip 30 is cut off on weakened points 31, thereby obtained non-textile strip section 11.
Afterwards, non-textile strip section 11 is wound up self, formed tampon base 12 as shown in Figure 5, the shaping of this blank is as shown in Figure 3, by self being entwined with its coiling mandrel 33 that vertically intersects.This forming process can be referring to Fig. 4, then non-textile strip 11 is reeled by following situation, the i.e. other end 11d of non-textile strip end 11 of the skin one end 11a of the non-textile strip section 11 of Juan Raoing and the coiling that places the bottom, overlap, they are all at the circumferencial direction (seeing Fig. 3 and Fig. 5) of tampon base 12, can obtain on its excircle, be columniform material distribution uniform tampon base 12 basically.
By Fig. 5 obviously as can be known, the thermoplasticity length of the band section 15 of liquid thoroughly is to be enough to make band section 15 to surround the circumference of tampon base 12 fully, and has covered its width.Freely or an end 15a of not sealing-in be at first be projected into the outside, when band section 15 this freely not the 15a of sealing-in end by after adding hot pressing, on the circumferencial direction of tampon base 12 during with the contiguous position sealing-in of non-textile strip section 11, when instant heating plasticity band section 15 was sealed to non-textile strip section 11, then winding process had promptly come to an end.Because at this time, the polyethylene from high pressure process surface of this melting fiber is supported each other, and sealing-in pressure does not just need than band section 15 has been sealed to the pressure height of non-textile strip 30.
According to Fig. 3, before operating winding, take out knot 13 and be on the axial direction that lies across non-textile strip section 11 and be placed on non-textile strip section 11 limits.If necessary, on its free end, beaten a knot, the tampon base of having made 12 is put in the compressor, according to DRP description 1,491,161, this compressor has comprised the claw that becomes star, and tampon base 12 pressurizeds are shaped within it, forms radial net shape as shown in Figure 6, tampon 10 put into the constriction end 10b that end 10a has become round layer top shape so that tampon can more easily be put into the abdominal cavity.In present method, do not need at length to narrate and take out knot and how to use, and with wherein.
Need not explain that we just can understand, the length of band section 15 is the final diameters that depend on tampon base 12, and the length of the not seal end 15a that freely gives prominence to of band section 15 also is to depend on this factor, and generally is to be about 10～50 millimeters.
Obviously; by Fig. 2～6 as can be known; but thermoplastic member's section of being with 15 of sepage; the neat outside that has covered non-textile strip 30 widely; it is to be extended to edge 11b by the dimension of non-textile strip 30; formed the pull end 10c of tampon 10; has only the longitudinal edge 11c that always extends to non-textile strip section 30; just form putting into of tampon 10 and held 10a; the longitudinal edge 11c that is not covered by thermoplasticity band section 15 in the non-textile strip 30 will have certain width; when being pressed into the final structure of tampon 10 with convenient tampon base 12; band section 15 can be transported into the neck down portions 10b of the circle layer top shape of putting into end 10a of tampon 10; this has just guaranteed simultaneously; the end 10a that puts into that does not comprise band 15 directly is subjected to be inhaled good liquid; then tampon expands without delay, thereby can absorb fully thus, and is protected effect fully with the person.Because its friction effect is lower, then the nonwoven material of thermoplasticity can guarantee that tampon more easily successfully puts into intraperitoneal, and can prevent to take place when using tampon to put into or taking out the abdominal cavity coming off of fiber.In addition because its non-woven fabric matter of sliding band section 15 that can force rate tampon periphery also wants big, therefore, can resist when tampon when intraperitoneal takes out, what may occur loses its spiral-shaped tendency.
Fig. 7 has shown the device according to the preparation tampon of said method of the present invention.Left-hand component among the figure has shown one from feeding roller 50, the continuous non-textile strip 30 that transports along the x direction of motion, deliver to puncture device 51 by roller 50 always, backing roll 52 is equipped with in puncture device 51 fronts, device 51 has comprised a pair of punching and pinch roll 53 and a pair of take-up roll 54 on the direction of motion of non-textile strip 30, because at the time nuclear of tension, this punching and pinch roll 53 have blocked 54 fronts and non-textile strip before take-up roll.And, because by means of its tension claw 54a, this take-up roll 54 can make the non-textile strip of being clamped by its claw produce the acceleration of an x direction, therefore, non-textile strip 30 attenuation at the position between punching and pinch roll 53 and take-up roll 54, or dwindled its cross section, thereby obtained weakened points 31.Top position in the non-textile strip direction of motion, conveying roller 55 has been closelyed follow in puncture device 51 back, lower position on non-textile strip tracks, an endless belt conveyer 56 has been closelyed follow in puncture device 51 back, this conveyer belt 56 is around front wheel driving and draw companion's roller 56a, and this roller 56a just in time is below conveying roller 55.These endless belt 56 other ends are around deflection roll 56b.
Sealing-in device 60 has comprised a pressure roll 57 below non-textile strip 30 moving tracks, its axostylus axostyle 58 two ends are placed in different 59, in different, compress under the effect of spring 61, can be up and down, by means of different 59, the pressure roll 57 that spring is housed can move on the direction of sealing-in roller 62 discontinuously.For example, can be by means of eccentric (not shown), can be the suitable method heating of sealing-in roller 62 usefulness, for example heat with resistance wire, roller 62 also can the counter-clockwise direction transmission, in addition, at sealing-in roller 62 other ends big deflection roll 63 and little deflection roll 64 are housed, primary deflector roller 64 be placed on big deflection roll 63 the direction of motion x of non-textile strip 30 order above by the back position on, around sealing-in roller 62 and two deflection roll 60 and 64, an annular sealing-in band 65 is arranged, with 65 is to be made by the heat proof material for the temperature of sealing-in 62, but can be delivered to the outside of annular sealing-in band 65 to the heat of sealing-in roller 62 by it, is used in that best material is silicone rubber or strip steel on the sealing-in band 65, these materials can be on the heat transferred thermoplasticity band section 15 on the sealing-in roller 62, and can the footpath durable for a long time.Process the surface of the sealing-in band 65 of different types according to the pattern of required sealing-in, with the bonding point (face of weld 79 is asked for an interview Fig. 3) that enables between non-textile strip 30 and band section 15, to provide adjacent at interval.
Obviously,, above puncture device 51 and non-textile strip 30, a feed roller 66 is arranged, constantly provide nonwoven to shearing device 70 with deflection roll 67 by spring-loaded in 60 fronts, sealing-in position, but sepage and thermoplastic fibrous matter.
Cut off roller 69 and laterally cut band 32, but do not cut off fully, make that still being so-called " silk screen " shape with the band of back by the band section 15 of cutting the front that forms follows mutually.
There is vacuum furnace 71 shearing device 70 back, and the detailed description of its structure is asked for an interview Fig. 8, do more detailed explanation according to the description of illustrated improved embodiment below.At the vacuum furnace top margin acceleration roller 72 of a minor diameter is arranged, it be in order to non-textile material cramping on vacuum furnace 71.The garden circular velocity of vacuum furnace 71 and acceleration roller 72 is identical with the delivery rate of non-textile strip 30, on vacuum furnace 71 garden perimeter surface, many holes have been beaten, hollow can being connected in vacuum furnace, can use or without vacuum pump (not shown) with vacuum pump.
Then, the band section of sending here from shearing device 70 15, can be gone up by the garden Zhou Fangxiang of vacuum furnace 71 and suck, by tension, redirecting to vacuum furnace 71 clockwise and to quicken in the roll gap between the roller 72, in case when the front end of band section 15 was incorporated in the roll gap that quickens between roller 72 and the vacuum furnace 71, then band section 15 was accelerated on the twice speed of non-textile strip, then, tear off fully at the cut-off part of shearing device 70 its non-textile strip 32 from behind.
By swabbing action, vacuum furnace 71 is incorporated into the band section 15 of garden on week attached to it by in the space that forms between vacuum furnace 71 and the annular sealing-in band 65 above the sealing-in roller 62.Since vacuum furnace 71 be with annular sealing-in band 65 to contacted, and be on the top position, front of sealing-in roller 62, and in this, on trip's phase inversion of vacuum furnace 71 is equidirectional, vacuum is cut off, as describing in detail below,, bond with the annular sealing-in band 65 of sealing-in roller 62 and heating as soon as possible and heat thermoplasticity band section 15.Then, when in the roll gap of further guiding between sealing-in roller 62 and the vacuum furnace 71, when it runs into non-textile strip 30, this band section 15 is given by annular sealing-in band 65 and having been heated earlier, so that the fiber of the fusing of band section 15 is fused in the roll gap between pressure roll 57 and the sealing-in roller 62, under suitable pressure and temperature condition, fibre compact is combined on the surface of non-textile strip.In the ring of top sealing-in band 65 encloses, below the tracks of non-textile strip 30, also has an endless belt conveyer 73, it is led by deflection roll 74, and it is the place ahead in non-textile strip tracks, and place the back of pressure roll 57, be in to close proximity non-textile strip 30 bottoms again, the band section 15 of non-textile material that conveyer belt 73 has been pressed non-textile strip and sealing-in, contact with the big deflection roll 63 of sealing-in band 65, this is because the deflection roll 75 of lower annular conveyer belt 73 is in the roll gap that is pressed between the little deflection roll 64 of its top of big deflection roll 63 and back, by other deflection or draw roll 76, make conveyer belt 73 can along non-textile strip 30 laterally, guiding downwards, endless belt 65 and 73 can make and can constantly carry with the non-band that spins of thermoplasticity band section 15 sealing-ins by up time dial or counter-clockwise to continuous running.As the result of above-mentioned deflection, it is separated on sealing-in endless belt 65 to guarantee to spin band section 11 with band section sealing-in non-.If necessary, can cool off deflection roll 63,64.
Fig. 2 has shown band section 15 has been sealed to the non-later non-textile strip 30 of rear end 11a that spins band section 11, obviously, the rear end 15a of band section 15 extends to non-textile strip 30 weakened points 31 outsides, extend to non-textile strip section 11 afterwards always, but be not sealed on the non-textile strip 30, in order to accomplish this point, therefore design saddle 59 and the pressure roll 57 that has spring, so that it can move up and down in the same way and oppositely with sealing-in roller 62, and handle it and make pressure roll 57 move down to disengage that its situation is asked for an interview Fig. 7 with non-textile strip 30.As its result, non-textile strip 30 sink between conveyer belt 56 and 73, and prop up on conveyer belt 73, and its deflection roll 74 is the tracks that relatively are lower than non-textile strip 30, when non-when spinning band 30 usefulness pressure rolls 57 and being pressed onto on the sealing-in roller 62, on the terminal region of endless belt 65, its temperature is low, so that can not be freely band section 15, the not softening or fusing of the fibrous matter of sealed end 15a, therefore, this end still continues sealing-in ground former state and stays on the non-textile strip 30.
There is adjustment or loose the back of endless belt 65 and endless belt 73, the area 77 of adjustment, and it is to be used for adjusting by certain-length at interval, band section 15 sealing-ins non-textile strip 30 in the above.In this area 77, non-textile strip is sagging between above-mentioned two endless belt conveyers and guide roller 78, and this is adjusted the area and just the intermittently operated process of the continued operation process of front and back has been separated.
There is the equipment component of non-textile strip shearing device guide roller 78 back, and it comprises a pair of clamp jaw 81, and this pawl touches mutually with non-top margin and the base of spinning band 30 tracks respectively, pivot back and forth enabling.Clamp jaw 81, face after the not sealing-in rear end 15a of band section 15, it is as described below to have clamped the non-textile strip section 11(that is placed on its front respectively off and on) so that can cut down non-textile strip section 11 from non-textile strip 30.
There are the clone of taking-up knot and knotting device 90 in the back of clamp jaw 81, and it is according to 1,491, No. 160 DRP description designs, thereby be not described in detail in this.Can point out fully, be placed on the non-textile strip section 11 taking out knot 13 with this device 90 that when cutting off and feed clamp 110 when non-textile strip section 11 is drawn, the free end that this taking-up is tied is to tie a knot together forward, this is as described below.Take out the knot 13 longitudinal edge 11b by non-textile strip section 11 and hang oneself (not shown), and formed the taking-up end 10c of tampon 10, non-textile strip section 11 is by aperture 83 gatherers 90.
