===present embodiment===
Fig. 2 A is the summary top view of the telescopic sheet 10 manufactured by the manufacturing installation 20 of present embodiment, and Fig. 2 B is the B-B direction view in Fig. 2 A.
This telescopic sheet 10 is along the continuous continuous serialgram 10 of direction, uses as the part of for example disposable diaper., this telescopic sheet 10 is to become final products intermediate products before.And described telescopic sheet 10 is as the functional features use of for example giving retractility to flank or the waist portion etc. of diaper.
Described telescopic sheet 10 has: a pair of serialgram 11,12, and through-thickness is engaged overlappingly; Many strand elastic 13,13 ..., by every being located at a pair of serialgram 11,12 each other.Strand elastic 13 along with the orthogonal width of the continuous direction of serialgram 11,12 time along above-mentioned continuous direction spaced apart configure many.And each strand elastic 13 is engaged with at least one party's serialgram 11(12 with elongation state) on.Therefore, by strand elastic 13,13 ... give the retractility of telescopic sheet 10 widths.; if each strand elastic 13,13 ... shrink; serialgram 11,12 also broad ways shrink and become the state that has multiple folds close; if but resist this strand elastic 13,13 ... contractility stretching serialgram 11,12; fold extends, and this serialgram 11,12 becomes the state of expansion.
In addition, in the example of Fig. 2 A, with respect to serialgram 11,12, strand elastic 13,13 ... be configured with certain disposition interval PO along continuous direction, but disposition interval PO be not limited to described equidistantly.For example, disposition interval PO also can periodically change.
In addition, in the example of Fig. 2 A, the end 13e of strand elastic 13 is outstanding from each ora terminalis 11e, the 12e of the width of serialgram 11,12, but its overhang L13e is in whole strand elastic 13,13 ... roughly the same in scope.And, can roughly unify like this overhang L13e, but about the principal character of the manufacturing installation 20 of present embodiment, explanation in the back.
But strand elastic 13 is can be not outstanding from ora terminalis 11e, the 12e of the width of serialgram 11,12 yet.For example, in manufacturing installation 20 described later, the size of contractility or the coating scope of bonding agent of the strand elastic 13 after being cut off according to the continuum 13a of strand elastic, as shown in Figure 2 C, be retracted to than each ora terminalis 11e, the 12e of serialgram 11,12 more in the inner part, and closed at completely in serialgram 11,12, in this situation, become the perfect telescopic sheet 10 of outward appearance.
Described strand elastic 13 is for example bonded with each other multiple elastic filament bunchy and forms, and elastic filament is the synthetic resin fiber of such as polyurethane fiber or ptt fiber etc.And, can enumerate " Lycra (trade mark) E.I.Du Pont Company " etc. as the concrete example of described strand elastic 13.In addition, the diameter of strand elastic 13 be for example non-elongation state be under the state of natural length for 0.2mm～0.5mm, under the state of 3 times that is elongated to natural length, be 0.1mm～0.3mm.
On the other hand, a pair of serialgram the 11, the 12nd, using non-woven fabrics, woven fabric, thin film etc. as material.And a pair of serialgram 11,12 both sides also can adopt identical material mutually, also can according to circumstances adopt different material mutually.In addition,, about the assortment of non-woven fabrics, woven fabric, thin film etc., can suitably use existing kind.About for example non-woven fabrics and woven fabric, also can use the cloth of the individual fibers of the thermoplastic resin system of polyethylene or polyethylene terephthalate etc., or the cloth of the composite fibre of use sheath core construct, can also combine them uses, in addition, for thin film, can illustrate the thin film of above-mentioned illustrative thermoplastic resin system etc.
In addition, at the bonding agent that is interval with of a pair of serialgram 11,12, engage respectively at least one party of a pair of serialgram 11,12 each other and in a pair of serialgram 11,12 serialgram 11(12 by this bonding agent) and each strand elastic 13,13 ... and become one.Can use for example PUR as described bonding agent.In addition, as bonding agent to serialgram 11(12) surperficial coating pattern can use multiple straight lines along continuous direction stripe arranged side by side on width, also multiple helixes along continuous direction helix picture group sample arranged side by side on width can be used, the so-called fixation pattern of coating adhesive in the whole region in regulation region can also be used.
Fig. 3 is the summary axonometric chart of the manufacturing installation 20 of telescopic sheet 10.
As shown in Figure 3, manufacturing installation 20 has: engaging mechanism 21, engages in the time that its continuous direction is carried overlappingly to a pair of serialgram 11,12; Conveying mechanism 31, towards by engaging mechanism 21 superimposed a pair of serialgram 11,12 that engages each other, carry the continuum 13a of strand elastic; Winding mechanism 41, when emitting the continuum 13a of strand elastic, is wrapped in above-mentioned conveying mechanism 31 with elongation state by the continuum 13a of strand elastic.
And conveying mechanism 31 is suitable with delivery section taking a pair of banded delivery section 32,32() as main body, each banded delivery section 32 is configured in respectively distolateral each position of more leaning on width than serialgram 11,12.In addition, each banded delivery section 32,32 can be carried along the length direction of self the continuum 13a of strand elastic, that is to say, carries the continuum 13a of strand elastic taking its length direction as throughput direction.
Therefore, the continuum 13a of strand elastic that is wrapped in a pair of banded delivery section 32,32 by winding mechanism 41 with broad ways across this pair of banded delivery section 32,32 state each other, towards engaging mechanism, 21 these sides are transferred successively, thus, under the state along width, be transported to a pair of serialgram 11,12 each other.
Here, a pair of banded delivery section 32,32 is suitable with transfer unit taking a pair of endless belt 33u, the 33d(that configure side by side along the direction (suitable with above-below direction in the example of Fig. 3) of intersecting with the throughput direction of continuum 13a and the width of serialgram 11,12 of strand elastic respectively) as main body, described a pair of endless belt 33u, 33d carry the continuum 13a of strand elastic with the state of difference with mutual transporting velocity value.Therefore, the part 13ac of the continuum 13a of the strand elastic of crossing over for broad ways, is wound around the difference of the inclination from width being endowed originally based on this transporting velocity value and is corrected gradually course of conveying.Its result, the part 13ac crossing over along above-mentioned width in the continuum 13a of strand elastic is to be engaged with on this sheet 11,12 with the state of the width almost parallel of serialgram 11,12.
And, be engaged with like this continuum 13a of the strand elastic on a pair of serialgram 11,12 after this joint, in distolateral each position of more leaning on width than serialgram 11,12, be cut off by cutting off parts 51,51, thus, strand elastic 13 is altered to independently strand elastic 13,13 from the state of continuum 13a ...About this situation, in the back explanation.
Below, describe about each structure 21,31,41,51.In addition, in the following description, also by with the orthogonal direction of the continuous direction of serialgram 11,12, the width of serialgram 11,12 is called " CD direction ".In addition, for ease of explanation, three mutually orthogonal directions are defined as to above-below direction, fore-and-aft direction, left and right directions.In addition, in this example, above-below direction is parallel with vertical direction, fore-and-aft direction and left and right directions and horizontal direction parallel.In addition, CD direction and left and right directions are identical directions.And the throughput direction of the continuum 13a of conveying mechanism 21 to strand elastic is parallel with fore-and-aft direction.In passing, " throughput direction " of fore-and-aft direction and claim is suitable, and " crisscross " of CD direction and claim is suitable, and " second is crisscross " of above-below direction and claim is suitable.
< < < engaging mechanism 21 > > >
Engaging mechanism 21 has the 21u of pair of rolls up and down, the 21d that are driven in rotation around rotating shaft C21u, C21d towards CD direction.And, it is suitable with the first roller that the serialgram 11 of a side in a pair of serialgram 11,12 is wrapped in top roll 21u(with the winding angle of regulation), in addition, serialgram 12 to be on the other hand wrapped in lower roll 21d(with the winding angle of regulation suitable with second roller) on.And, serialgram 11,12 is all retained the state roughly relatively not skidding between the outer peripheral face of roller 21u, the 21d that should be wound around arbitrarily, thus, follow the driving rotation of each roller 21u, 21d, each serialgram 11,12 becomes roughly one with the outer peripheral face of corresponding roller 21u, 21d, and being circumferentially transferred along this roller 21u, 21d.
And, outer peripheral face by pair of rolls 21u, 21d is each other below immediate position Pn(, also be called the position Pn that nips) time, the serialgram 11 of top and serialgram 12 through-thickness of below are that above-below direction is clamped overlappingly, thus, by being coated in advance the bonding agent at least one party who answers overlapping face, both are engaged.In addition, as mentioned above, before this joint, the continuum 13a of the strand elastic of elongation state is to be put into described a pair of serialgram 11,12 each other along the posture of CD direction (width), thereby in the time of above-mentioned joint, it is integrated that upper and lower each serialgram 11,12 and this three of continuum 13a of strand elastic become joint.
< < < conveying mechanism 31 > > >
Conveying mechanism 31 has respectively banded delivery section 32,32 in the left and right of CD direction.The mode that each banded delivery section 32 strides across engaging mechanism 21 about this fore-and-aft direction with its length direction towards the fore-and-aft direction time is configured, and thus, strides across engaging mechanism 21 ground and form the transport path of the continuum 13a of linear elastic bodies along fore-and-aft direction.
Each banded delivery section 32 has upper and lower a pair of endless belt 33u, 33d.Each endless belt 33u, 33d are wrapped in respectively on a pair of belt wheel 34u, 34u, 34d, 34d at the both ends that are disposed at fore-and-aft direction.And at least one party's belt wheel 34u, 34d is attached at servomotor 35u, the 35d as drive source, thus, can set respectively circular velocity value to each endless belt 33u, 33d.
In addition, according to belt wheel 34u, 34u, 34d, 34d towards setting, the surround orbit of each endless belt 33u, 33d has and is positioned at the distolateral distolateral track Tr1 of CD direction and is positioned at than distolateral track Tr1 more by the center side track Tr2 of the center side of CD direction.And, in distolateral track Tr1, each endless belt 33u, the 33d forwards, backwards front of direction move, and rearward move in center side track Tr2, thus, the continuum 13a that is wrapped in the strand elastic in a pair of banded delivery section 32,32 is kept by endless belt 33u, 33d, 33u, 33d mobile on distolateral track Tr1, thus, is also finally arrived engaging mechanism 21 by the front conveying of direction forwards, backwards.
In passing, the zone face of endless belt 33u, 33d towards being to become the be oriented basis parallel with CD direction with the normal direction of this face, also can be according to circumstances, this normal direction from CD direction for example to be greater than 0 ° of angular range that is less than 60 ° tilted.
Fig. 4 A to Fig. 4 C is the key diagram of the frame parts 36 of supporting endless belt 33u, 33d.Fig. 4 A is summary enlarged side view, and Fig. 4 B is the B-B direction view in Fig. 4 A, and Fig. 4 C is the C-C direction view in Fig. 4 A.
As shown in Fig. 4 B and Fig. 4 C, in the space between distolateral track Tr1 and center side track Tr2, every the frame parts 36 being provided with along fore-and-aft direction lengthwise.And, there are above-mentioned belt wheel 34u, 34d at the both ends fixed bearing of the fore-and-aft direction of this frame parts 36, in addition, there are above-mentioned servomotor 35u, 35d at its leading section fixed bearing.In addition, as shown in Fig. 4 A and Fig. 4 B, in this embodiment, frame parts 36 be also used as upper and lower a pair of endless belt 33u, 33d both.And, to prevent that this upper and lower a pair of endless belt 33u, 33d interference are each other as object, in upper and lower a pair of endless belt 33u, 33d position each other, a flank 36r along fore-and-aft direction gives prominence to the distolateral of CD direction from each side of frame parts 36, by described flank 36r, upper and lower a pair of endless belt 33u, 33d are separated each other intangibly.And, at the regulation position of described flank 36r, be formed with the slot part 36rt along fore-and-aft direction, in described slot part 36rt, be inserted with blade tip 52e continuum 13a, cut-out parts 51 for cutting off strand elastic, but about this situation, in the back explanation.
< < < winding mechanism 41 > > >
As shown in Figure 3, winding mechanism 41 is wrapped in the continuum 13a of strand elastic the suitable winding parts of bobbin etc. with coiled type from the coil case 13C(of strand elastic) when emitting the continuum 13a of strand elastic, be wrapped in the rearward end 31b of conveying mechanism 31.Thus, this winding mechanism 41 has: emit portion 43, emit the continuum 13a of strand elastic from the coil case 13C that can rotate freely the strand elastic that floor-covering roll cylinder mechanism 42 supports; Wound portion 46, is wrapped in the continuum 13a of the strand elastic of emitting from the portion of emitting 43 the rearward end 31b of conveying mechanism 31.
Emit portion 43 in being arranged on coil case 13C drum mechanism built 42 and emitting the continuum 13a of strand elastic and the tension force of this continuum 13a is set in the tension range of regulation after, with the feed speed value (m/ divides) of the regulation corresponding with this speed of wrap value, the continuum 13a of strand elastic is supplied with to wound portion 46 linkedly with the speed of wrap value (m/ divides) of wound portion 46.
Here, mentioned strain scope is that the minimum tension force in the unflagging scope of continuum 13a based on strand elastic is preset, for example 0.0298N～0.098N.And thus, substantially, the speed of wrap value of wound portion 46 becomes the elongation multiplying power of the continuum 13a of the strand elastic in the winding moment being wrapped on conveying mechanism 31 with respect to the ratio of the feed speed value of the portion of emitting 43.Therefore, adjust linkedly feed speed value with speed of wrap value, thus, can roughly with the elongation multiplying power of target, the continuum 13a of strand elastic be wrapped on conveying mechanism 31 all the time.In passing, extend multiplying power refer to strand elastic continuum 13a in be elongated to the index of the state of several times from its natural length, for example obtain divided by natural length LO as the length L S with elongation state remove calculation value (=LS/LO).
As described concrete structure example of emitting portion 43, can be listed below structure, the continuum 13a of strand elastic from the coil case 13C of drum mechanism built 42 to the feed path of wound portion 46, have: tension controller 44, be arranged on the position of upstream side, approach the position of coil case 13C; Donor rollers 45, is arranged on the more position of downstream of ratio tension controller 44 in this feed path, approaches the position of wound portion 46.Here, tension controller 44 is that the mode converging in the tension range of regulation with the tension force of the continuum 13a of the strand elastic of its nearest downstream position is carried out feedback control to the discharging amount from coil case 13C, as its concrete structure example, have: sensor 44s, measures the tension force of above-mentioned nearest downstream position; Emit and use driving pulley 44p, be arranged on the position of more leaning on the upstream side of driving path than the measuring position of this sensor 44s.And, converge on the mode of above-mentioned predefined tension range with the measured value of the tension force from sensor 44s output, emitting with the drive source of driving pulley 44p is that servomotor (not shown) is controlled by suitable control device.
Fig. 5 is the summary central cross-sectional view of wound portion 46.As shown in Figure 5, wound portion 46 taking approach conveying mechanism 31 rearward end 31b configure have round-ended cylinder parts 46a as main body.Having the cylinder axle C46a of round-ended cylinder parts 46a is the osculum kernel of section position that is set at conveying mechanism 31, with the cross section being specified by above-below direction and CD direction on the axle C46a of roughly the same position, center, and, be the axle C46a setting substantially in parallel with fore-and-aft direction.And, drive rotation to have round-ended cylinder parts 46a around cylinder axle C46a.This drive source uses for example servomotor 49rn.; in the example of Fig. 5; rearward be wholely set highlightedly coaxially path cylinder 47 from the bottom 46ab that has round-ended cylinder parts 46a with cylinder axle C46a; fixed drive belt wheel 49p coaxially on described path cylinder 47, the driving spinning movement of the driving rotating shaft 49s of servomotor 49m is transfused to this driving belt wheel 49p by timing belt 49b.And, thus, there is round-ended cylinder parts 46a to drive rotation.
In addition, in the multiple positions that have in round-ended cylinder parts 46a, be provided with pulley 48p, 48p, the 48p of the continuum 13a that is wound around strand elastic.These pulleys 48p, 48p, 48p be by from the portion of emitting 43 with transport condition to the continuum 13a of the strand elastic that has round-ended cylinder parts 46a to be supplied to the guiding parts of throw-in part 48t guiding that is arranged on the conveying mechanism 31 the leading section 46af of round-ended cylinder parts 46a.
Specifically, pulley 48p, 48p, 48p are arranged on respectively the front position of the inner circumferential side of path cylinder 47, the back-end location of cylindrical portion 46at that has round-ended cylinder parts 46a and the front position of this cylindrical portion 46at, and, in this front position, be provided with in addition to drop into as above-mentioned throw-in part 48t and use pulley 48t.
And the continuum 13a of the strand elastic being supplied to from the portion of emitting 43 is wrapped in each pulley 48p, 48p, 48p with said sequence, thus, the continuum 13a of strand elastic arrives above-mentioned throw-in part 48t as described below.; first; the continuum 13a of the strand elastic being supplied to from the portion of emitting 43 arrives the front position of this path cylinder 47 by the inner circumferential side of path cylinder 47; then; by the pulley 48p of this position, travel direction is transformed into round-ended cylinder parts 46a radial direction outside and travel along the bottom 46ab that has round-ended cylinder parts 46a.And, travel by this, arriving this has the back-end location of the cylindrical portion 46at of round-ended cylinder parts 46a, but by the pulley 48p of this back-end location, again travel direction is transformed into front and arrives the front position of this cylindrical portion 46at.And, finally, be directed to the throw-in part 48t of this position by the pulley 48p of this front position.
In addition, throw-in part 48t drops into and is configured to and has the cylinder axle C46a of round-ended cylinder parts 46a parallel with the rotating shaft C48t of pulley 48t self.Therefore, this pulley 48t can have the rearward end 31b inner circumferential side of round-ended cylinder parts 46a, conveying mechanism 31 to drop into towards being positioned at the continuum 13a of strand elastic smooth and easy and rapidly.
In addition, about the position of fore-and-aft direction, there are the leading section 46af of round-ended cylinder parts 46a and the rearward end 31b of conveying mechanism 31 overlapping., the rearward end 31b of conveying mechanism 31 has in round-ended cylinder parts 46a from there being the leading section 46af of round-ended cylinder parts 46a to be inserted into this.Therefore, the continuum 13a of the strand elastic that can reliably the throw-in part 48t from front position be put into the rearward end 31b of conveying mechanism 31, is wrapped in the periphery of the rearward end 31b of conveying mechanism 31.
< < < cuts off parts 51 > > >
Fig. 6 A and Fig. 6 B are the key diagrams that cuts off parts 51.Fig. 6 A is summary top view, and Fig. 6 B is the B-B direction view in Fig. 6 A.In addition,, in Fig. 6 A, serialgram 11,12 is not shown.
As shown in Fig. 3 and Fig. 6 A, cut off parts 51,51 and be configured in accordingly with each banded delivery section 32,32 distolateral each position of more leaning on CD direction than conveying mechanism 31 respectively.And, each parts 51 that cut off are in self responsible position, from the distolateral continuum 13a that blade tip 52e is pressed against to strand elastic of CD direction, thus, the continuum 13a that cuts off strand elastic, cuts out and generates independently strand elastic 13,13 from this continuum 13a ...; the part 13ac that a pair of banded delivery section 32,32 arranged side by side is crossed over the continuum 13a of the strand elastic forming along CD direction in CD direction is cut out from the continuum 13a of strand elastic by the cut-out of cut-out parts 51; its result, this part 13ac is assembled into serialgram 11,12 as strand elastic 13 independently.
In passing, described cut-out parts 51 are about the position of fore-and-aft direction, at the position Pn position Pc more on the front that nips of the 21u of pair of rolls up and down, 21d than engaging mechanism 21, that is to say the position Pc in the downstream of throughput direction, cut off the continuum 13a of strand elastic.In more detail, from nip position Pn with the value (=PO/2) of the half of the disposition interval PO of strand elastic 13 than the position in downstream more the position Pc of downstream cut off.And if cut off at this position Pc,, after the position Pn that nips is bonded on serialgram 11,12 by the continuum 13a of strand elastic securely, the continuum 13a of strand elastic is cut off.Therefore the above-mentioned independently strand elastic 13, forming by this cut-out can prevent because engaging bad from serialgram 11,12 disengagings reliably.
In addition, as shown in Figure 6B, upper and lower a pair of endless belt 33u, the 33d that cut-out parts 51 have in banded delivery section 32 position each other cuts off the continuum 13a of strand elastic., in this position, as described above, the flank 36r of the frame parts 36 of banded delivery section 32 is distolateral outstanding to CD direction, and, on flank 36r, being formed with the slot part 36rt along fore-and-aft direction, the blade tip 52e that cuts off parts 51 is inserted in this slot part 36rt from the distolateral of CD direction.Therefore, cutting off parts 51 for example, cuts off in upper and lower a pair of endless belt 33u, 33d position (, endless belt 33u, 33d centre position each other) each other.
And, now, according to the geometric relation of the winding shape of the continuum 13a of strand elastic, cut off in above-mentioned position, thus, in the banded delivery section 32,32 of pair of right and left, in leap pair of right and left, under the part 13ac of the continuum 13a of endless belt 33u, 33u strand elastic each other and leap pair of right and left, the part 13ac of the continuum 13a of endless belt 33u, 33u strand elastic is each other cut off into roughly the same length (Fig. 6 A) mutually.Thus, after being shunk by the cut-out end 13e that cuts off the independently strand elastic 13 forming, the length of the distolateral outstanding strand elastic 13 from serialgram 11,12 to CD direction becomes the roughly state of alignment.
In addition, from Fig. 6 A and Fig. 6 B, in this embodiment, use swivel knife 52 as described cut-out parts 51.Swivel knife 52 is for example disc parts 52 of positive toroidal, and its outer peripheral edges 52e becomes blade tip 52e in all-round scope.And swivel knife 52 is taking the spindle unit 52s that arranges coaxially and integratedly with its center of circle C52 as rotating shaft C52 rotation.Specifically, this spindle unit 52s can rotate freely on the suitable fixed class parts 55 that are supported in production line by bearing 53.In addition, in described spindle unit 52S, be endowed driving revolving force from the servomotor 53m as drive source by the suitable drive mechanism of belt wheel 53p, 52p and timing belt 53t etc., thus, swivel knife 52 drives rotation.Therefore, bring into play high cuttability.
And, as shown in Figure 6A, in this embodiment, swivel knife 52 is arranged on than the continuum 13a of strand elastic and more leans on the distolateral of CD direction, and cut off below the position Pc(of continuum 13a of strand elastic, being called off-position Pc) direction of rotation of the swivel knife 52 located is towards the rightabout of throughput direction, that is to say rear.Specifically, this off-position Pc refers to that to start the position Pc that contacts with the continuum 13a of strand elastic roughly suitable with the blade tip 52e of swivel knife 52, but the direction of rotation in the nearest downstream of described off-position Pc as shown in Fig. 6 A empty arrow towards rear and CD direction distolateral.Therefore, can make to follow the powdery fragment that cuts off the strand elastic 13 producing to disperse to the distolateral of CD direction, its result, can prevent that described fragment is involved in to serialgram 11,12 effectively.
But, direction of rotation towards being not limited to this., as shown in Figure 6 C, rotation that also can be contrary to the above, if like this, can improve cuttability.Details is as described below.
In the example of this Fig. 6 C, swivel knife 52 is also arranged on than the continuum 13a of strand elastic and more leans on the distolateral of CD direction.But, about the direction of rotation of the swivel knife 52 at off-position Pc place, identical with the throughput direction of the continuum 13a of strand elastic, that is to say towards front.Thus, when the continuum 13a of strand elastic is cut off in swivel knife 52, swivel knife 52 is pressed into the continuum 13a of strand elastic to the center side of CD direction.On the other hand, the flank 36r of upper and lower a pair of endless belt 33u, 33d and frame parts 36 is positioned at the center side of more leaning on CD direction than the continuum 13a of strand elastic.Therefore, by being pressed into center side of above-mentioned swivel knife 52, the mode of further not escaping to center side with the continuum 13a of strand elastic, the flank 36r of this upper and lower a pair of endless belt 33u, 33d or frame parts 36 can press from central thruster the continuum 13a of strand elastic, its result, can improve the cuttability of swivel knife 52.
In addition, as shown in Figure 6B, be inserted into blade tip 52e in the slot part 36rt of flank 36r of frame parts 36, swivel knife 52 not cut off with the mode that clamps the continuum 13a of strand elastic together with the bottom surface of slot part 36rt.,, there to be the mode in suitable gap between the continuum 13a of the strand elastic in cut-out and the bottom surface of slot part 36rt, the depth dimensions (mm) of design slot part 36rt and blade tip 52e are to the insertion (mm) of slot part 36rt.Therefore, can suppress the wearing and tearing of the blade tip 52e of swivel knife 52, its result, realizes the long lifetime of swivel knife 52.
As an example of described swivel knife 52, can illustrate the swivel knife of for example ultramicron superhard (Super micro-gain carbide) system, more particularly, can illustrate Kyoto Ceramic Co., Ltd's rounding cutter (production code member FRC28L, 40 ° of the basils).
In addition, about the blade tip shape of swivel knife 52, can be also any one of a sword and two-edged, but, as shown in Figure 6B, use two-edged here.But, about the basil, compared with the little basil such with 10 ° or 20 ° etc., preferably 40 ° of above so large basils, if like this, in the case of the swivel knife 52 of the superhard system of above-mentioned ultramicron, the ultramicron that is embedded in a large amount of high rigidity in the mother metal of blade tip 52e is difficult to come off from mother metal, its result, realizes the long lifetime of swivel knife 52.
In passing, the peripheral speed value (m/ divides) of swivel knife 52, the rotary speed value (m/ divides) at blade tip 52e place with the balance of cuttability by experiment or trial run etc. suitably determine.And, for example, if the peripheral speed value of swivel knife 52 is set for to the more than 1.5 times of transporting velocity value (m/ divides) of the throughput direction (fore-and-aft direction) of the continuum 13a of conveying mechanism 31 to strand elastic, can bring into play good cuttability.
In addition, with reference to Fig. 6 C, as mentioned above, make the direction of rotation of swivel knife 52 become identical with throughput direction towards situation under, preferably, the transporting velocity value (m/ divides) of setting the peripheral speed value of swivel knife 52 for than the conveying mechanism 31 continuum 13a to strand elastic greatly, more preferably, similarly becomes more than 1.5 times with above-mentioned.And, if like this, can bring into play good cuttability.
