Next, major part of the present invention is described.
This manufacturing installation, as following detailed description, has holding section 5 pinching nip rolls 4.As shown in Figure 8, described holding section 5 engages along with the described direction comprising the component of the tangential direction T such as circumferential R pinching nip rolls 4 with described elastic component F in the transmission of described elastic component F, for suppress or prevent elastic component F relative to pinch nip rolls 4 surface occur slide situation.
In case of the present embodiment, described holding section 5 is by giving prominence to multiple protuberances 51 of submerging and recess 50 is formed along the described radial N pinching nip rolls 4,4, described protuberance 51 engages along the direction of the component comprising described tangential direction T with described elastic component F.Described protuberance 51 is formed as the cone-shaped that thickness reduces along with the foreign side of pinching the radial N of nip rolls 4 towards described, and described protuberance 51 engages with described elastic component F.
As shown in Figure 1 and Figure 6, described holding section 5 is arranged throughout the described complete cycle pinching nip rolls 4,4, and be configured in each described in pinch the both ends 41 in the outside of the described width Y of the nip portion 40 of the clamping described S of nip rolls 4.It should be noted that, in figure 6, elastic component F only illustrates 1.
As shown in Figure 9, described holding section 5 can be formed by the plate 53 separated with described roller main body of pinching nip rolls 4.
The plate 53 with described holding section 5 is arranged on the both ends 41 of pinching on the axial Y of nip rolls 4, thus as shown in Figure 6, described holding section 5 is configured in the both ends 41 of pinching nip rolls 4.More specifically, as shown in Figure 9, with according to pinch described in each protuberance 51 that nip rolls 4,4 arranges to be positioned at the position be separated from each other mode one another along the described axial Y pinching nip rolls 4,4 by a pair plate 53,53 vertically Y mutually depart from configuration.
Next, the preferred detailed construction of described recess 50 and protuberance 51 is described.
As shown in Fig. 9 amplifies, described protuberance 51 is more outstanding to the foreign side of described radial N than the outer surface 42 of described nip portion 40.That is, the external diameter of described plate 53 is greater than the external diameter of nip portion 40.
As shown in Figure 8, the external diameter of the plate 53 of described recess 50 can be greater than the external diameter of nip portion 40, otherwise but also can be less than, can also be identical.Described holding section 5 has the well-regulated concavo-convex of waveform.
It should be noted that, schematically illustrate elastic component F and recess 50 in fig. 8.
Described recess 50 can be the channel-shaped that extends of Y (Fig. 9) vertically.Such as, although the degree of depth of the recess 50 of channel-shaped also depends on the thickness of elastic component F, can be about 0.1 ~ 0.5mm.The thickness of the plate 53 of described Fig. 9 can be about 0.5mm ~ 5mm.
Next, manufacture method is described.
Driven by drive unit 3 at the conveyer belt 11 ~ 14 of Fig. 1 and under the state that rotates, elastic component F stretches out from circulator 2, elastic component F reels around conveyer belt 11 ~ 14 with a state of establishing.Thus, elastic component F around conveyer belt 11 ~ 14 spirally circumvolution, while transmitted by the downstream towards direction of transfer X.
That is, first F1 and second F2 of elastic component F is relative to axial Y with the state slightly tilted, and is transmitted along the upper surface of conveyer belt 11 ~ 14 and lower surface.Then, first and the 4th conveyer belt 11,14 and the speed difference of second and third conveyer belt 12,13 that drives with low velocity VL that at full speed VH due to Fig. 4 drives, as shown in Figure 5, first F1 and second F2, while close abreast along the axial Y pinching nip rolls 4, supplies to pinching between nip rolls 4,4.
That is, described elastic component F supplies between two sheets S, S to described by the state be separated from each other along described direction of transfer X with first F1 and second F2 of described elastic component F.Now, described first F1 and second F2 supplies between two sheets S, S to described with the state be separated from each other along the thickness direction Z of described S shown in Fig. 7 A.
In other words, from the position that the shared tangent line TL pinching nip rolls 4,4 relative to two of Fig. 7 A departs to thickness direction Z, described first and second F1, F2 are supplied between sheet S, S.
On the other hand, although described two sheets S, S pinch between nip rolls 4,4 to a pair and supply, but described S, S and first and second F1, F2 arrive pinch nip rolls 4,4 pinch folder point O during, need to suppress elastic component F that the situation of sliding occurs relative to sheet S.
A part of the elastic component F of Fig. 7 A is transferred into when pinching position that nip rolls 4 connects via described S, and the two ends of a part of the elastic component F of Fig. 6 enter the recess 50 of holding section 5.In this case, as shown in Figure 8, be located at the holding section 5 of pinching nip rolls 4,4 before pinching folder point O described in arrival, engage with described elastic component F along the direction of pinching the component of the tangential direction T of nip rolls 4 described in comprising, the circumferential R transmission of nip rolls 4 will be pinched described in described elastic component F edge.
Therefore, elastic component F with on the circumferential R pinching nip rolls 4 almost skid-resistant mode be transferred into pinch folder point an O.Then, pinch nip rolls 4,4 by described a pair and described elastic component F is clipped in described between two sheets S, S, the elastic component F of Fig. 7 B is configured with the state of bonding to two sheets S, S in rapid succession.
After described configuration, that is, described elastic component F be sandwiched in described a pair between S, S after, as shown in Figure 2, between described first F1 and second F2, utilize cutter C to be cut off by described elastic component F.
Like this, generate first F1 and second F2 to be alternately parallel to each other and the flexible duplexer W configured regularly with the spacing specified.
In the present invention, as the concaveconvex shape of described holding section 5, the various shapes of Figure 10 A ~ Figure 10 C can be adopted.It should be noted that, when the groove of the such arc-shaped of Fig. 8, easily keep the elastic component F of circular section, and pinching a folder point O place, recess 50 not easily blocks and is hung on elastic component F.
In addition, in the present invention, the external diameter of the protuberance 51 of described holding section 5 can be less than the external diameter pinching nip rolls 4, that is, protuberance 51 is without the need to giving prominence to relative to the outer surface 42 pinching nip rolls 4.Its reason is, elastic component F with pinch after nip rolls 4 contacts, as shown in Figure 9, elastic component F bends at the end place of pinching nip rolls 4 and engages with the protuberance 51 of holding section 5.Therefore, described protuberance 51 can be kept out of the way from the nip portion 40 of pinching nip rolls 4.
Based on same reason, protuberance 51, without the need to giving prominence to along the radial N (Fig. 8) pinching nip rolls 4, when being located at pinch nip rolls 4 both ends 41, as shown in Figure 10 D, can be given prominence to from the two ends of pinching nip rolls 4 along the axial Y pinching nip rolls 4.
And described holding section 5, without the need to being formed at plate 53, also can being carved on the surface at the both ends 41 of pinching nip rolls 4 and establish groove to form described holding section.
In addition, described holding section 5, without the need to being formed by multiple groove, can be the structure that the such multiple nadel of such as male face fastener or metal plug engages with elastic component F.
In addition, as long as described holding section 5 is arranged at least one party pinched for a pair in nip rolls 4,4.Such as, when the side in first F1 and second F2 of the elastic component F of Fig. 7 A being transmitted on shared tangent line TL, the elastic component F of this side does not need the guiding of described holding section 5.Therefore, as long as only arrange holding section 5 to the elastic component F of the opposing party.
