Further, a protective material such as rubber or felt is attached to the surface of the sandwiching piece 44a on the material holding surface 42 side so as not to damage the metal foil 1 or the insulating adhesive film 2. Here, the clamp tool 43 is exemplified by a pair of clamp members 44, 44. However, the present invention is not limited to this. For example, the clamp tool 43 is composed of a clamping piece and mounting pieces provided on both side ends thereof. You may form with a letter-shaped member.

  The elevating body 41 is disposed inside the base 40 so as to be movable up and down by a driving machine such as an air cylinder, and bar support portions 47 project from both side ends of the upper surface thereof. Further, a holding bar (paper passing bar) 31 is detachably attached to the elevating body 41 so as to span the bar support portion 47. The holding bar 31 is formed of a cylindrical body such as a metal or plastic pipe. As shown in FIG. 4, the longitudinal direction of the holding bar 31 is the rotating shaft 13 of the rolls 3 and 4 and the rotating shaft 12 of the winder 5. It is attached to the raising / lowering body 41 so that it may become parallel with respect to. The holding bar 31 is provided with a slit 33 over substantially the entire length in the longitudinal direction. The slit 33 opens to the peripheral surface of the holding bar 31 and reaches the inner space of the holding bar 31 and is also used as a suction port 34 to be described later.

  As shown in FIGS. 5 (a) and 5 (b), the lifting body 41 can be adjusted to two height positions H1 and H2. The height position of one raising / lowering body 41 is a roll replacement height position H1, and when the rolls 3 and 4 are replaced with new ones, the initial metal foil 1 and the insulating adhesive film 2 are positioned with respect to the holding bar 31. This is the height position set when stacking. The height position of the other lifting / lowering body 41 is a winder replacement height position H2, and the winder 5 that has wound the metal foil 1 and the insulating adhesive film 2 by a predetermined length (number of times) is wound by another winder. This is the height position that is set when the metal foil 1 and the insulating adhesive film 2 that are in the process of being stacked are positioned and stacked with respect to the holding bar 31 when the tool 5 is replaced. Further, the winder replacement height position H2 can be set to a plurality of height positions.

  Then, when stacking a plurality of combination materials A in which two metal foils 1, 1 and one insulating adhesive film 2 are stacked using the stacking apparatus as described above, the following is performed.

  First, the lower metal foil 1 is pulled out from the roll 3 and held and set in the material setting machine 30. As shown in FIG. 6A, the metal foil 1 is set by placing the metal foil 1 pulled out from the roll 3 so as to exceed the upper side of the holding bar 31 attached to the material setting machine 30, As shown in FIG. 6B, the tip of the metal foil 1 is disposed between the clamping pieces 44a and 44a of the lowermost clamp members 44 and 44 and the material holding surface 42, and the clamping pieces 44a and 44a. By moving the clamp members 44, 44 so as to approach the material holding surface 42, both end portions of the metal foil 1 are interposed between the sandwiching pieces 44a, 44a and the material holding surface 42 as shown in FIG. Clamp the part. Here, the height position of the elevating body 41 of the material setting machine 30 is a roll replacement height position H1. Further, the metal foil 1 set in the material setting machine 30 is disposed in contact with the upper surface of the holding bar 31, and the clamping pieces 44a, 44a of the uppermost and middle clamp members 44, 44 and the material holding surface 42 are disposed. It is arranged so as to pass between.

  Next, the insulating adhesive film 2 is pulled out from the roll 4 arranged between the upper and lower metal foils 1, 1 and held and set in the material setting machine 30. At this time, the insulating adhesive film 2 is set by disposing the insulating adhesive film 2 drawn from the roll 4 so as to exceed the upper side of the metal foil 1 set in the material setting machine 30, and Is disposed between the clamping piece 44a, 44a of the middle clamping member 44, 44 and the material holding surface 42, and the clamping member 44, 44 is moved so that the clamping piece 44a, 44a approaches the material holding surface 42. 6 (d), the both end portions of the insulating adhesive film 2 and the both end portions of the set metal foil 1 are clamped (clamped) between the holding pieces 44a, 44a and the material holding surface 42. ) Here, the height position of the elevating body 41 of the material setting machine 30 is the same roll replacement height position H1 as described above. Further, the insulating adhesive film 2 is disposed in contact with the upper surface of the metal foil 1 set in the material setting machine 30, and the clamping pieces 44a and 44a of the uppermost clamp members 44 and 44 and the material holding surface 42 are disposed. It is arranged so as to pass between.

  Next, the upper metal foil 1 is pulled out from the roll 3 and held and set in the material setting machine 30. At this time, the metal foil 1 is set by placing the metal foil 1 drawn out from the roll 3 so as to exceed the upper side of the insulating adhesive film 2 set in the material setting machine 30, It arrange | positions between the clamping piece 44a, 44a of the uppermost clamp members 44 and 44, and the material holding surface 42, and this clamping piece 44a, 44a approaches the material holding surface 42, as shown in FIG.6 (e). By moving the clamp members 44 and 44 in such a manner, the both end portions of the metal foil 1 and the both end portions of the insulating adhesive film 2 are set between the sandwiching pieces 44 a and 44 a and the material holding surface 42. The both end portions of the metal foil 1 are clamped (clamped). Here, the height position of the elevating body 41 of the material setting machine 30 is the same roll replacement height position H1 as described above. The metal foil 1 set on the material setting machine 30 is disposed in contact with the upper surface of the insulating adhesive film 2 set on the material setting machine 30.

  Through the above operation, as shown in FIG. 7, the two metal foils 1, 1 and the one insulating adhesive film 2 are sequentially stacked on the upper surface of the holding bar 31, and then the fixing cover 48 and the lock member are stacked. The metal foils 1, 1 and the insulating adhesive film 2 are fixed and set to the holding bar 31 by a pressing tool 35 composed of 49. That is, as shown in FIGS. 8A and 8B, the fixed cover 48 formed in a substantially C-shaped cross section with a metal plate or plastic is elastically applied to the holding bar 31 from the surface side of the outermost metal foil 1. The metal foils 1 and 1 and the insulating adhesive film 2 are sandwiched between the fixed cover 48 and the holding bar 31 over the entire length in the width direction, and as shown in FIG. The fixed cover 48 is fixed to the holding bar 31 by sandwiching both end portions 48a of the 48 and the holding bar 31 with a lock member 49 such as a clip. At this time, the slit 33 of the holding bar 31 is positioned directly below the end portion 48 a of the fixed cover 48 on the winder 5 side.

  Next, the metal foils 1 and 1 and the insulating adhesive film 2 that are held and set on the holding bar 31 are cut. As shown in FIG. 9, the cutting is performed by inserting the cutter (blade) 32 from the surface of the outermost metal foil 1 and inserting the cutter 32 into the slit 33 in the longitudinal direction of the slit 33. Move along. Further, at the time of cutting, a hose 51 is connected to the end opening of the holding bar 31 and air is sucked into the inner space of the holding bar 31 through the hose 51 by the vacuum pump 50 or the like. And dust generated by the cutting of the insulating adhesive film 2 can be sucked and removed from the slit 33 which is the suction port 34, and the dust does not adhere to the metal foil 1 or the insulating adhesive film 2 so It is possible to prevent a molding defect from occurring in the laminated board B. In this example, the slit 33 and the suction port 34 are used together, but the suction port 34 may be formed in the holding bar 31 separately from the slit 33. Then, by this cutting, a part of the metal foil 1 and the insulating adhesive film 2 located below the holding bar 31 is cut off, and the tip of the metal foil 1 after cutting and the insulating adhesive film 2 after cutting are cut. The metal foils 1, 1 and the insulating adhesive film 2 can be positioned on each other in the width direction and laminated on the surface of the holding bar 31 in a state in which the leading ends of the two metal foils 1, 1 are aligned. A pair of combination materials A can be formed with the insulating adhesive film 2 sandwiched therebetween.

  Thereafter, the holding bar 31 is removed from the lifting body 41 of the material setting machine 30 while holding the metal foils 1, 1 and the insulating adhesive film 2, and the holding bar 31 is attached to the winder 5 supported by the bearing 19. To the vertical frame members 16 and 16 as one horizontal frame member 17 of the winder 5. In this way, the front end of the combination material A can be held at one place on the outer surface of the winder 5. Next, by rotating the winder 5 in one direction, the metal foil 1 is unwound from the roll 3 and the insulating adhesive film 2 is unrolled from the roll 4 to wind the combination material A around the winder 5. it can. The combination material A in which the insulating adhesive film 2 is overlapped between the two metal foils 1 and 1 is wound up in a state of being stacked in multiple layers on the outer surface of the winder 5. In the case of being formed of a flat body, the combination material A can be stacked on both surfaces of the winder 5 in a state of being folded at both ends of the winder 5 (between the outer sides of the horizontal frames 17 and 17). Is. In addition, the raising / lowering body 41 is located below the roll replacement height position H1 so that the metal foil 1 and the insulating adhesive film 2 do not hit the material setting machine 30 when the combination material A is wound by the winder 5. Move it like so.

  Here, when the metal foil 1 and the insulating adhesive film 2 are unwound from the rolls 3 and 4 and wound around the winder 5, when the rolls 3 and 4 rotate freely, the metal foil 1 and the insulation are rotated by the rotation of the winder 5. There is a possibility that the rolls 3 and 4 rotate due to the inertia faster than the speed at which the adhesive film 2 is taken, and at this time, the metal foil 1 and the insulating adhesive film 2 wound around the winder 5 may be wrinkled. In particular, when the winder 5 is a flat body, the speed at which the metal foil 1 and the insulating adhesive film 2 are taken up varies depending on the rotation angle of the winder 5, and thus such a problem is likely to occur. Therefore, in the present invention, when the winder 5 is rotationally driven to draw out the metal foil 1 or the insulating adhesive film 2 from the rolls 3 and 4 and wound around the winder 5, the rolls 3 and 4 are rotated. The brake mechanism 6 applies braking so that the rolls 3 and 4 rotate with inertia at a speed faster than the speed at which the metal foil 1 and the insulating adhesive film 2 are taken along with the rotation of the winder 5. It is possible to take up the metal foil 1 and the insulating adhesive film 2 without causing wrinkles. It can be wound around the tool 5. Further, the speed at which the metal foil 1 and the insulating adhesive film 2 are taken up varies depending on the rotation angle of the winder 5, but the rotation angle of the winder 5 is detected by the rotation angle detector 14, and the metal foil 1 and the insulating adhesive are bonded. When the film 2 is pulled out at a high rotation angle, the braking strength by the brake mechanism 6 is weakened, and when the speed at which the metal foil 1 or the insulating adhesive film 2 is pulled out is slow, the braking strength by the brake mechanism 6 is reduced. In order to increase the thickness, by controlling the strength of the rotational braking of the rolls 3 and 4 in inverse proportion to the speed at which the metal foil 1 and the insulating adhesive film 2 are pulled out by the winder 5, the metal foil 1 and the insulating adhesive The film 2 can be wound around the winder 5 with a certain tension applied. Therefore, in this case, the metal foil 1 and the insulating adhesive film 2 can be wound around the winder 5 without causing wrinkles and without damaging the metal foil 1 and the insulating adhesive film 2. .

  After the combination material A is wound around the winder 5 in this way, when the combination material A is removed from the winder 5, the combination material A is wound in a flat spiral shape as shown in FIG. The combination material A in which the insulating adhesive film 2 is stacked between the two metal foils 1 and 1 is in a state of being stacked in a large number in the vertical direction. Thus, the combination material A in which the metal foil 1 and the insulating adhesive film 2 are stacked can be stacked by unwinding the metal foil 1 and the insulating adhesive film 2 from the rolls 3 and 4 and winding them on the winder 5. The combination material A can be easily and highly productive without problems of labor and work, as in the case of stacking the metal foil 1 and the insulating adhesive film 2 cut to a predetermined size one by one. It can be stacked. In particular, when the metal foil 1 and the insulating adhesive film 2 cut to a predetermined size are stacked one by one, the stacking operation time becomes long, and foreign matter is mixed between the metal foil 1 and the insulating adhesive film 2. However, as a result of the quick stacking of the combination material A, such contamination can be reduced. In addition, since the metal foil 1 and the insulating adhesive film 2 are positioned and laminated in advance before being wound around the winder 5 using the material setting machine 30, the metal foil 1 and the insulating adhesive film 2 are misaligned. Thus, it is possible to prevent the combination material A from being wrinkled or distorted.

  Here, when removing the winder 5 from the spiral combination material A, it can be performed by disassembling the winder 5 by removing the coupling of the horizontal frame 17 and the vertical frame 16, At this time, the holding member 35 can be removed from the holding bar 31 that is the horizontal frame member 17 to release the holding of the combination material A from the holding bar 31. Further, the combination material A is placed on the carrier plate 9 together with the winder 5 as shown in FIG. 11A, and the coupling between the horizontal frame 17 and the vertical frame 16 is released as shown in FIG. 11B. By disassembling, the horizontal frame body 17 can be removed from the spiral combination material A as shown in FIG. Thus, the winder 5 can be easily removed from the spirally wound combination material A.

  Then, the combination material A stacked as described above is sandwiched between the carrier plate 9 and the plate plate 11 formed of metal plates as shown in FIG. 10B (if necessary, the carrier plate 9 and the plate 11 A plurality of sets of combination materials A may be sandwiched between them), and further, by setting this between the heating plates 10 and 10, it is possible to perform heat and pressure molding, and the insulating adhesive film 2 A double-sided metal foil-clad laminate B in which metal foils 1 and 1 are laminated on both sides can be formed. The laminated board B obtained by molding in this way has a flat spiral shape, but by cutting the bent portion (the cut portion is indicated by a chain line in FIG. 10 (b)), a flat double-sided metal The foil-clad laminate B can be obtained.

  In the above description, when the metal foil 1 and the insulating adhesive film 2 are all fed out from the rolls 3 and 4 and then the new metal foil 1 and the insulating adhesive film 2 are set on the rolls 3 and 4, the metal foil 1 1 and the method of winding the insulating adhesive film 2 on the winder 5 have been described. In the present invention, the combination material A (the metal foil 1 and the insulating adhesive film 2) having a predetermined length (number of times) is wound on the winder. Even if the metal foil 1 and the insulating adhesive film 2 are not all drawn out from the rolls 3 and 4 after being wound up in the roll 5, the work of replacing the roll with another winder 5 may be continued. In this case, it is necessary to position and laminate the metal foil 1 and the insulating adhesive film 2 in advance before winding the combination material A on the other winder 5 to be replaced. Therefore, in the present invention, the winder 5 is replaced as follows.

  First, the rotation drive of the winder 5 is stopped, and the drawing of the metal foils 1 and 1 and the insulating adhesive film 2 from the rolls 3 and 4 is stopped. Next, the lifting body 41 to which the holding bar 31 is attached is raised, and the metal foils 1 and 1 and the insulating adhesive film 2 spanning between the winder 5 and the rolls 3 and 4 are lowered by the holding bar 31. The metal foils 1, 1 and the insulating adhesive film 2 are overlapped on the surface of the holding bar 31 by slightly pressing from the side. At this time, the elevating body 41 is moved up to the winder replacement height position H2 above the roll replacement height position H1. When the rolls are replaced with new rolls 3 and 4, since the holding work to the holding bar 31 can be performed with the tips of the metal foil 1 and the insulating adhesive film 2 being free, the roll replacement height position H1 is workability. Can be set to a position lower than the winder replacement height position H2. However, when it is replaced with a new winder 5, the metal foils 1, 1 and the insulating adhesive film 2 are in a state of being slightly separated from each other in the vertical direction, and are hung between the winder 5 and the rolls 3, 4. Since it is in a crossing state, the metal foils 1, 1 and the insulating adhesive film 2 are brought into contact with each other by raising the elevator 41 up to the winder replacement height position H 2 higher than the roll replacement height position H 1. However, it is necessary to overlap on the surface of the holding bar 31. Therefore, the winder replacement height position H2 is set to a position higher than the roll replacement height position H1.

  Next, in the same manner as described above, the metal foils 1 and 1 and the insulating adhesive film 2 are fixed and set to the holding bar 31 by the presser 35 including the fixed cover 48 and the lock member 49. Next, in the same manner as described above, the metal foils 1 and 1 and the insulating adhesive film 2 which are set while being held by the holding bar 31 while being sucked are cut. And by this cutting | disconnection, the metal foil 1 and the insulating adhesive film 2 by the side of the winding tool 5 rather than the holding bar 31 and the metal foil 1 and the insulating adhesive film 2 by the side of the roll 3 and 4 from the holding bar 31 are separated. The

  Next, after removing the winder 5 that has wound the combination material A from the bearing 19, another new winder 5 is attached to the bearing 19. Next, the holding bar 31 is removed from the lifting body 41 of the material setting machine 30 while holding the metal foils 1 and 1 and the insulating adhesive film 2, and the holding bar 31 is attached to the winder 5 supported by the bearing 19. To the vertical frame members 16 and 16 as one horizontal frame member 17 of the winder 5. Thus, after holding the front-end | tip of the combination material A in one place on the outer surface of the winder 5, the winder 5 is rotationally driven in one direction in the same manner as described above, so that the metal foil 1 is rolled. Then, the insulating adhesive film 2 is respectively unwound from the roll 4 so that the combination material A is wound around the winder 5. In order to prevent the metal foil 1 and the insulating adhesive film 2 from hitting the material setting machine 30 when the combination material A is wound by the winder 5, the lifting body 41 is positioned below the roll replacement height position H1. It is the same as the above to move it.

  In this way, even before the metal foil 1 and the insulating adhesive film 2 are all pulled out from the rolls 3 and 4, the combination material A can be continuously wound up by replacing with the new winder 5. In this case as well, the metal foil 1 and the insulating adhesive film 2 can be aligned in advance before the winder 5 with the material setting machine 30, so that the metal foil 1 and the insulating adhesive film 2 are misaligned. It is possible to prevent the combination material A from being wrinkled or distorted without being wound on the winder 5 in the state.

  FIG. 12 shows an embodiment in which the winder 5 is formed in a flat plate shape with a smooth surface. The winder 5 is formed of, for example, a rectangular metal plate, and a rotation shaft 12 is provided at the center of two opposing sides. When such a winder 5 is used, the tip of the combination material A is wound up by joining the holding bar 31 holding the metal foil 1 and the insulating adhesive film 2 to one side where the rotating shaft 12 is not provided. It can be held at one place on the outer surface of the tool 5. Then, in the same manner as described above, the winder 5 is also driven to rotate around the rotary shaft 12, thereby winding the metal foil 1 or the insulating adhesive film 2 between the opposite edges of the winder 5, Similarly to the above, the combination material A composed of the metal foil 1 and the insulating adhesive film 2 can be wound in a flat spiral shape so as to be stacked.

  When this flat plate-shaped winder 5 is used, it does not become a hindrance at the time of carrying out the heating-press molding of the combination material A. For this reason, as shown in FIG. 13, the combination material A is sandwiched between the carrier plate 9 and the plate 11 while being wound in a flat spiral shape on the winder 5 (if necessary, the carrier plate 9 and the plate 11), a plurality of sets of combination materials A may be sandwiched between each other), and further, this is set between the hot plates 10 and 10 and subjected to heat and pressure molding to form the metal foil 1 on both surfaces of the insulating adhesive film 2. , 1 can be formed into a double-sided metal foil-clad laminate B. As described above, since the heat and pressure molding can be performed while the combination material A is wound around the winder 5, it is not necessary to remove the combination material A from the winder 5. In addition, by forming the winder 5 with a metal plate, the heat at the time of heating and pressing can be made uniform by heat transfer by the metal plate, and the laminated plate B having a stable quality by making the heating temperature uniform. Further, even if foreign matter is present on one side of the winder 5, molding defects due to the presence of the foreign matter do not reach the other side of the winder 5, reducing the occurrence of defects. Is something that can be done.

  Further, when the winder 5 is formed of a flat plate having a smooth surface, the winder 5 and the rotary shaft 12 may be formed separately. For example, in the embodiment shown in FIG. 14, the rotation shaft 12 is provided in a U-shaped sandwiching jig 22 formed of a chuck tool or the like, and the sandwiching jig 22 is detachably attached to both sides of the winder 5. It is designed to be attached to the winder 5. When the rotary shaft 12 is integrally provided on both side surfaces of the winder 5 as in the embodiment of FIG. 12, the winder 5 needs to be formed thicker according to the diameter of the rotary shaft 12. However, if the winder 5 and the rotary shaft 12 are formed separately as in the embodiment of FIG. 14, the winder 5 can be made thinner. . Therefore, in this case, the folded-back bent portion when the combination material A is wound around the winder 5 becomes thin, and the portion to be cut and discarded after the lamination molding is reduced, so that the material loss can be reduced. Moreover, when the winding tool 5 which wound up the combination material A is piled up and down in a plurality of stages and laminated molding as shown in FIG. 13 is performed, the number of stacking stages of the winder 5 which wound up the combination material A may be increased. It is possible to increase the productivity of laminate molding.

  FIG. 15 shows another example of a method of winding up two metal foils 1 and 1 and one insulating adhesive film 2 using the stacking device. This method is a two-stage method using two holding bars 31 a and 31 b as the holding bar 31. First, the upper metal foil 1 is pulled out from the roll 3 and held and set on a holding bar 31 a arranged in the material setting machine 30. The method for setting the metal foil 1 at this time is the same as the method shown in FIGS. Next, the single metal foil 1 arranged in contact with the upper surface of the holding bar 31a is fixed and set to the holding bar 31a by the presser 35 including the fixing cover 48 and the lock member 49 in the same manner as described above. . Next, the metal foil 1 set on the holding bar 31a is cut by the cutter 32 in the same manner as described above. Thereafter, the holding bar 31a is removed from the material setting machine 30 while the metal foil 1 is positioned and held, and the holding bar 31 is carried to the winder 5 as indicated by an arrow a. The horizontal frame member 17 is coupled to the vertical frame members 16 and 16.

  Next, after the other holding bar 31 b is set on the material setting machine 30, the lower metal foil 1 is pulled out from the roll 3 and held and set on the holding bar 31 b of the material setting machine 30. The method for setting the metal foil 1 at this time is the same as the method shown in FIGS. Next, the insulating adhesive film 2 is pulled out from the roll 4 arranged between the upper and lower metal foils 1, 1 and held and set in the material setting machine 30. The method of setting the insulating adhesive film 2 at this time is the same as the method shown in FIG. After holding the metal foil 1 and the insulating adhesive film 2 on the holding bar 31b as described above, the metal foil 1 and the insulating adhesive are bonded by the pressing member 35 including the fixed cover 48 and the lock member 49 in the same manner as described above. The film 2 is fixed to the holding bar 31b and set. Next, the metal foil 1 and the insulating adhesive film 2 positioned and set on the holding bar 31b are cut by the cutter 32 in the same manner as described above. Thereafter, the holding bar 31b is removed from the material setting machine 30 while the metal foil 1 and the insulating adhesive film 2 are held, and the holding bar 31b is carried to the winder 5 as shown by an arrow B, and wound. The other horizontal frame member 17 of the handle 5 is coupled to the vertical frame members 16 and 16.

  In this way, the tip of one metal foil 1 can be held at one place on the outer surface of the winder 5, and the other metal foil 1 and the insulating adhesive film 2 can be held at one end of the outer surface of the winder 5. Although one metal foil 1 and the other metal foil 1 are held by holding bars 31a and 31b attached to one end and the other end of the winder 5, respectively, The tip of the metal foil 1 and the tip of the other metal foil 1 are separated by the length of the winder 5 (the distance between the holding bars 31a and 31b attached to the winder 5). Then, by rotating the winder 5 in one direction with the holding bars 31a and 31b attached to both ends, the metal foil 1 is fed out from the roll 3 and the insulating adhesive film 2 is fed out from the roll 4, respectively. A combination material A composed of a piece of metal foil 1, 1 and a piece of insulating adhesive film 2 can be wound around a winder 5. The combination material A in which the insulating adhesive film 2 is overlapped between the two metal foils 1 and 1 is wound in a state where a large number of layers are stacked on the outer surface of the winder 5 in the same manner as described above. When the winder 5 is formed of a flat body, the combination material A is provided on both surfaces of the winder 5 in a state of being folded at both ends of the winder 5 (between the outer sides of the horizontal frames 17 and 17). Can be stacked. The combined material A wound up in this way is wound with the tip portion 1a of the upper metal foil 1 being longer than the lower metal foil 1 or the insulating adhesive film 2 by the length of the winder 5. As shown in FIG. 16, the portion where the tip portion 1a of the upper metal foil 1 is located in the center portion in the thickness direction of the wound combination material A and the metal foil 1 is overlapped in three layers is formed. In other portions, the metal foil 1 and the insulating adhesive film 2 are laminated. Therefore, the central portion in the thickness direction of the combination material A can be easily discriminated by the three-layer portion of the metal foil 1, and workability in the case of dividing the combination material A into two parts can be improved. Is.

  In the above description, the lamination of the two metal foils 1 and 1 and the insulating adhesive film 2 has been described. However, the present invention is not limited to this, and the present invention is not limited to this. It can also be applied to the lamination of. For example, by disposing a plurality of rolls 4 wound with an insulating adhesive film 2 between a pair of rolls 3 wound with a metal foil 1, a plurality of insulating adhesive films 2 between the two metal foils 1, 1. It is also possible to form the combination material A so as to be sandwiched between them. One of the pair of rolls 3 may be one in which a release film such as a PPS film or a fluororesin film is wound instead of the metal foil 1. Further, when the insulating adhesive film 2 is formed by bonding only one side and the other side being a non-adhesive surface, one roll 3 wound with the metal foil 1 and one roll wound with the insulating adhesive film 2 are used. The roll 4 may be used in combination, and the metal foil 1 may be wound around the winder 5 as a combination material A in which the insulating adhesive film 2 is overlapped on the adhesive surface.
