In addition, the part of exposing from sheet S, S of the elastic component F of cut-out is shunk because tension force is removed.
The flexible duplexer W so generating is along being cut off in length and breadth, is used as a part for described flank sheet etc.
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 in the transmission of described elastic component F along the direction with the described component that comprises tangential direction T of pinching nip rolls 4 for example circumferentially R engage with described elastic component F, for suppressing or preventing elastic component F with respect to the situation of pinch nip rolls 4 surface generation slip.
The in the situation that of the present embodiment, described holding section 5 is by forming along described outstanding a plurality of protuberances 51 and the recess 50 submerging of radially N of pinching nip rolls 4,4, and described protuberance 51 engages with described elastic component F along the direction of the component that comprises described tangential direction T.Described protuberance 51 forms along with the foreign side towards the described radially N that pinches nip rolls 4 and the cone-shaped that thickness reduces, and described protuberance 51 engages with described elastic component F.
As shown in Figure 1 and Figure 6, described in described holding section 5 spreads all over, pinch the complete cycle setting of nip rolls 4,4, and be configured in the both ends 41 in outside of described width Y of the folder portion 40 of pinching of the described S of clamping that pinches nip rolls 4 described in each.It should be noted that, in Fig. 6, elastic component F only illustrates 1.
As shown in Figure 9, described holding section 5 can be formed by the plate 53 separating 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 on the axial Y that pinches nip rolls 4, thereby 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 described in each, pinch protuberance 51 that nip rolls 4,4 arranges is positioned at the position being separated from each other mode one another along the described axial Y that pinches nip rolls 4,4 by a pair of plate 53,53 vertically Y mutually depart from configuration.
Next, the preferred detailed structure of described recess 50 and protuberance 51 is described.
As shown in Fig. 9 amplifies, the outer surface 42 of pinching folder portion 40 described in described protuberance 51 compares is outstanding to the foreign side of described radially N.That is, the external diameter of described plate 53 is greater than the external diameter of pinching folder 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 pinching folder 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, in Fig. 8, schematically illustrate elastic component F and recess 50.
Described recess 50 can be the groove shape that Y (Fig. 9) extends vertically.For example, although the degree of depth of the recess 50 of groove shape also depends on the thickness of elastic component F, can be 0.1～0.5mm left and right.The thickness of the plate 53 of described Fig. 9 can be 0.5mm～5mm left and right.
Next, manufacture method is described.
At the conveyer belt 11～14 of Fig. 1, driven and under the state that rotates, elastic component F stretches out from circulator 2 by drive unit 3, elastic component F reels around conveyer belt 11～14 to establish state.Thus, elastic component F is on one side around spirally circumvolution of conveyer belt 11～14, and one side is transmitted towards the downstream of direction of transfer X.
That is, the First F1 of elastic component F and second F2 be the state slightly to tilt with respect to axial Y, along upper surface and the lower surface of conveyer belt 11～14, is transmitted.Then, the speed difference of the first and the 4th conveyer belt 11,14 driving due to the at full speed VH of Fig. 4 and second and third conveyer belt 12,13 with low velocity VL driving, as shown in Figure 5, First F1 and second F2 approach abreast along the axial Y that pinches nip rolls 4 on one side, to pinch nip rolls 4,4 between supply with on one side.
That is the state, being separated from each other along described direction of transfer X with the First F1 of described elastic component F and second F2 is supplied with described elastic component F between described two sheet S, S.Now, the state that described First F1 and second F2 are separated from each other with the thickness direction Z along described S shown in Fig. 7 A is supplied with between described two sheet S, S.
In other words, the position of departing to thickness direction Z from pinch the shared tangent line TL of nip rolls 4,4 with respect to two of Fig. 7 A is supplied with described First and second F1, F2 between sheet S, S.
On the other hand, although described two sheet S, S supply with to a pair of pinching between nip rolls 4,4, 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 the situation of sliding occurs with respect to sheet S.
A part of the elastic component F of Fig. 7 A is transferred into when pinching the position that nip rolls 4 joins 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.Under this state, as shown in Figure 8, be located at pinch nip rolls 4,4 holding section 5 before pinching folder point O described in arriving, along the direction of component of pinching the tangential direction T of nip rolls 4 described in comprising, engage the circumferential R transmission of pinching nip rolls 4 described in will described elastic component F edge with described elastic component F.
Therefore, elastic component F is to be transferred into and to pinch a folder point O pinching on the circumferential R of nip rolls 4 almost skid-resistant mode.Then, by the described a pair of nip rolls 4,4 of pinching, described elastic component F is clipped between described two sheet S, S, by the elastic component F of Fig. 7 B in rapid succession to two sheet S, S with bonding state configuration.
After described configuration, that is, after described elastic component F is sandwiched between described a pair of S, S, as shown in Figure 2, between described First F1 and second F2, utilize cutter C that described elastic component F is cut off.
Like this, generate First F1 and second flexible duplexer W that F2 is alternately parallel to each other and configures regularly with the spacing of stipulating.
In the present invention, as the concaveconvex shape of described holding section 5, can adopt the various shapes of Figure 10 A～Figure 10 C.It should be noted that, in the situation that the such circular-arc groove of Fig. 8 easily keeps the elastic component F of circular section, and pinching folder point O place, recess 50 is difficult for card 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 of pinching nip rolls 4, that is, protuberance 51 is without outstanding with respect to the outer surface 42 of 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 and engages with the protuberance 51 of holding section 5 at the end place of pinching nip rolls 4.Therefore, described protuberance 51 can be kept out of the way from pinching the folder portion 40 of pinching of nip rolls 4.
Reason based on same, protuberance 51, without outstanding along the radially N (Fig. 8) that pinches nip rolls 4, in the situation that be located at the both ends 41 of pinching nip rolls 4, as shown in Figure 10 D, can be given prominence to along the axial Y that pinches nip rolls 4 from pinching the two ends of nip rolls 4.
And described holding section 5 is without being formed at plate 53, also can carves on the surface of pinching the both ends 41 of nip rolls 4 and establish groove and form described holding section.
