C and 11R are provided. Other configurations are basically the same as those shown in FIGS. Metal band running part 1
With the metal bands 2, 13 positioned to the left, the tips of the metal bands 3, 4 are fixed to the laminating work table 2 as necessary, and from this state, the metal band running section 13 is moved to the right to make the laminating work table 2
The metal band 4 is laminated on the substrate. Next, the sheet-shaped synthetic resin material 9 is laminated on the metal band 4, and then the metal band running portion 12 is moved to the right to laminate the metal band 3 via the sheet-shaped synthetic resin material 9. Then, the insulating intermediate plate 10 is laminated to form a state as shown in FIG. At this time, the impact force relaxing portions 11L, 11C, 11R are located on the right side. From the state shown in FIG. 21, the impact force reducing portion 11L is positioned above the right end face of the insulating intermediate plate 10 as shown in FIG. 22, and then as shown in FIG.
The second travel assist roll 18 is moved upward. Next, the metal band running portion 12 is moved to the left, and the metal band 3 is applied to the impact force relaxing portion 11 to reduce the impact force. From this state, the metal band running portion 12 is further moved to the left to stack the metal bands 3 as shown in FIG. 24, and the impact force relaxing portion 11L is moved left to retract the impact force relaxing portion 11L, as shown in FIG. As shown in the figure, the metal band running part 12 and the impact force reducing part 11L are moved to the left end, and the metal band running part 1 is moved.
The second travel assist roll 18 is lowered. Next, the sheet-shaped synthetic resin material 9 is laminated on the metal band 3, and the impact force reducing portion 11 </ b> C is moved above the right end surface of the insulating intermediate plate 10 as shown in FIG. The travel assist roll 18 is moved upward. Next, as shown in FIG. 27, the metal band running portion 13 is moved to the left, and the metal band 3
Is applied to the impact force reducing portion 11C to reduce the impact force. From this state, the metal band running portion 13 is further moved to the left to stack the metal bands 4 and the impact force relaxing portion 11C to the left as shown in FIG. To retract the impact force relaxing portion 11C, and as shown in FIG. 29, move the metal band running portion 13 and the impact force relaxing portion 11C to the left end, and lower the traveling assist roll 18 of the metal band running portion 13 downward. . Next, as shown in FIG.
Then, it is moved above the left end face of No. 0, the insulating intermediate plate 10 is laminated in the same manner as above, and the metal bands 3 and 4 are laminated in the same manner as above.

Next, an example shown in FIG. 31 will be described. This has an impact force reducing portion 11 that receives the impact force applied to the metal bands 3 and 4 on the entire folded surface. That is,
When the width of the metal bands 3 and 4 is LI, the length L2 of the impact force relaxing portion 11 is longer than the length L1. In this way, the impact force applied to the metal bands 3 and 4 can be absorbed (dispersed) in the entire area of the impact force reducing portion 11 in contact with the metal bands 3 and 4, and the manufactured laminate is less likely to wrinkle.

Next, an example shown in FIG. 32 will be described. This has an impact force reducing portion 11 that receives an impact force applied to the metal bands 3 and 4 partially against the folded surface. That is, the impact force reducing portion 11 is formed by a pair of divided bodies 11a, and only the widthwise ends of the metal bands 3 and 4 are in contact with the impact force reducing portion 11. The impact force reducing portion 11 having such a structure can be reduced in size.

Next, an example shown in FIG. 33 will be described. This is because the shape of the contact surface of the impact force reducing portion 11 with the metal bands 3 and 4 is rounded. In other words, as shown in FIG. 33, the metal band contact surface 24 of the impact force reducing portion 11 is a predetermined arcuate arc surface. By doing so, the contact of the impact force relaxing portion 11 with the metal bands 3 and 4 becomes smooth, and the metal bands 3 and 4 are hardly broken.

Next, an example shown in FIG. 34 will be described. This is a roller in which the impact force reducing section 11 is rotatable. That is, the impact force relaxing portion 11 is formed in a columnar shape that is long in the lateral direction, and both ends of the impact force relaxing portion 11 are rotatably mounted on the base portion 25 by the bearing 26. In this case, when the metal bands 3 and 4 come into contact with the impact force relaxing portion 11, the impact force relaxing portion 11 rotates like a roller, friction with the metal bands 3 and 4 is reduced, and scratches are less likely to occur.

Next, an example shown in FIG. 35 will be described. This has notches 27 on both side surfaces of the impact force reducing portion 11 that contact the metal bands 3 and 4. That is, the notches 27 are provided on both sides of the shock absorbing portion 11 at portions corresponding to both sides in the width direction of the metal bands 3 and 4. Assuming that the dimension in the direction perpendicular to the central portion in the longitudinal direction of the impact force relaxing portion 11 is b, the portion with the notch 27 has an a size smaller than the b size. In this case, since the notch 27 is formed in the buffering force relaxing portion 11 at a position corresponding to both ends in the width direction of the metal bands 3 and 4 that are easily broken, the impact force is applied to both ends in the width direction of the metal bands 3 and 4. In addition, the metal bands 3 and 4 are less likely to be torn than those having uniform dimensions in the longitudinal direction.

Next, an example shown in FIG. 36 will be described. This is because the impact force reducing portion 11 has a bow shape on the surface where the metal bands 3 and 4 are in contact. In other words, both ends in the longitudinal direction of the impact force reducing portion 11 are thinner than the central portion. The dimension at both ends is smaller than the dimension c at the center, d. Also in this case, the metal band 3,
4 at positions corresponding to both ends in the width direction.
Has a notch in the metal band 3,
The metal bands 3 and 4 are less likely to be torn, without being applied to both ends in the width direction of the metal band 4. Further, since the shape of the impact force relaxing portion 11 is continuously changed, it is possible to cope with a difference in the width of the metal bands 3 and 4.

Next, an example shown in FIG. 37 will be described. This is one in which the shape of the insulating intermediate plate 10 has notches 28 on both sides of the folded surfaces of the metal bands 3 and 4. This is because not only the impact force is reduced by the impact force reducing portion 11 as described above, but also the notch 28 is formed at the portion of the insulating intermediate plate 10 that contacts the widthwise ends of the metal bands 3 and 4.
You are using something. Both ends in the width direction of the metal bands 3 and 4 where the impact force tends to concentrate and cracks do not hit the insulating intermediate plate 10, and the metal bands 3 and 4 are not cut or torn.

Next, the example of FIG. 38 will be described. This is one in which the impact force reducing portion 11 is an elastic body. In the case of this example, an elastic material 30 such as a rubber-based material is wound around an outer surface of a metal pipe 29 such as an aluminum pipe having a hollow inside. When the impact force of the metal bands 3 and 4 is reduced by using the impact force reducing portion 11, the elastic material 30 absorbs the impact force, so that the metal bands 3 and 4 are less likely to be torn.

Next, an example shown in FIG. 39 will be described. This is a mechanism in which the impact force reducing section 11 has elasticity, and is attached to the apparatus main body 1. Both ends of the impact force reducing portion 11 are held by the impact force relaxing holding portion 31 via the bearing 26, and the impact force reducing portion fixing clamp jig 34 provided on the apparatus body 1 side.
, An impact force alleviating holding portion 31 is attached via a spring material 32. The spring member 32 is attached in a direction to reduce a force in a direction to which an impact force is applied. That is,
The direction in which the impact force is applied (G direction) is the same as the direction in which the spring material 32 expands and contracts (H direction). Thereby, the impact force applied to the metal bands 3 and 4 can be absorbed by the spring material 32, and the metal bands 3 and 4 are not broken.

[0025]

As described above, according to the present invention, when the metal band is folded at the end surface of the insulating intermediate plate, the metal band is first brought into contact with the impact force reducing portion to reduce the impact force applied to the metal band and then folded. Thus, it is possible to prevent the adverse effect that the metal band is cut off, to eliminate the trouble in the manufacturing process, to improve the productivity and to improve the quality.
