。Methods for joining belt-shaped metal plates include a method in which the belt-shaped metal plates are joined by overlapping each other, and a method in which the belt-shaped metal plates are joined by butting each other.
前記帯状金属板同士を重ね合わせて接合する方法には、
第７図に示すように、帯状金属板６０と帯状金属板６２
とを重ね合わせ、接合面６４を、両面接着テープで接着
する方法や超音波で融着接合する方法がある（特開昭５
９−２４５２６号公報）。The method of overlapping and joining the band-shaped metal plates includes:
As shown in FIG. 7, a band-shaped metal plate 60 and a band-shaped metal plate 62
There is a method of superimposing the two and bonding the joint surface 64 with double-sided adhesive tape or fusion bonding using ultrasonic waves (Japanese Patent Application Laid-Open No.
9-24526).

2 and the ends 66, 66 of the single-sided adhesive tape 6.
8 and 68, there is a method of joining the band-shaped metal plates 60 and 62 (Japanese Unexamined Patent Publication No. 59-24526).

る。However, in the method of joining the band-shaped metal plates shown in FIG. 7, since there is a step in the joining part 65, it is not possible to smoothly roll the metal plate into contact with a pass roller or the like. Further, since the thickness of the joint portion 65 is thicker than the thickness of the belt-shaped metal plate and the joint surface 64 is often not joined over the entire area, the belt-shaped metal plate 60,
There is a possibility that the bonding surface 64 may turn over during transportation of the bonding surface 62. Furthermore,
There is a problem that the joint portion 65 comes into contact with other objects during transportation. In addition, during the process, the band-shaped metal plates 60 and 62 are
When treating the surface of the metal strips 60 and 62, when the metal strips 60 and 62 pass through the treatment liquid, the treatment liquid may enter the gap between the joint surfaces 64, causing quality defects in subsequent processes.

れる。On the other hand, in the method for joining band-shaped metal plates shown in FIG.
A problem similar to that of the metal strip shown in FIG. 7 occurs, and while the metal strips 60 and 62 are being conveyed by a bus roller or the like, the tapes 138 and 818 are scratched and cut at the edges of the ends 66 and 66. A problem arises in that it becomes easier. Furthermore, the tapes 68, 68 tend to break due to the bending stress they receive when passing through the pass rollers. For example, band-shaped metal plates 60, 6
If the plate thickness of the two metal plates 60 and 62 is between Q,l+mm and 0.2 mm, or if there is a large difference in the thickness of the two band-shaped metal plates 60 and 62 to be joined, rupture due to bending stress will occur significantly.

て提案されている（特願昭６２−１８１８９４号）。Therefore, in order to solve the various problems mentioned above, the metal strips 60 and 62 are butted together and welded, and then, as shown in FIG. The applicant of the present invention has proposed a joining method and an apparatus therefor in which the materials are held in between and rolled by a rolling roller 74 (Japanese Patent Application No. 181894/1989).

し易いという欠点がある。In addition, in order to further increase the strength of the welded joint 72, it is rolled using a rolling roller with minute protrusions so that the thickness difference near the heat-affected zone that occurs during welding is within 30%. A joining method has been proposed by the applicants of the present invention (Japanese Patent Application No. 63-108839) [Problems to be Solved by the Invention] However, when rolled with the rolling roller, the difference in plate thickness is more than twice as large. When joining band-shaped metal plates to each other, or when joining band-shaped metal plates with a plate thickness of 0.3aus or less,
The disadvantage is that distortions such as constrictions, wrinkles, and undulations are likely to occur in the welded joint.

ることなく十分な強度を得ることができる。According to the belt-shaped metal plate joining apparatus configured as described above,
The welded joint ffls 33 is first rolled by a rolling roller 34, and then the welded joint 33 is rolled by a rolling roller 36 located behind the rolling roller 34, as shown in FIG.
It is rolled so that there are no steps. Therefore, the welded joint 33 is rolled in two stages by one rolling movement of the rolling rollers 34 and 36, compared to the conventional rolling method using one rolling roller 74 shown in FIG. It is possible to suppress the occurrence of distortions such as constrictions, wrinkles, and corrugations caused by rolling, and sufficient strength can be obtained without increasing the cycle time.

接合邪３３から退避させる必要もなくなるので、溶接接
合部３３を均一に塗布することができる。On the other hand, the strip metal plate 1 joined using the rolling device 32
0 and 22 are smoothly conveyed by rolling contact with a large number of bus rollers while being subjected to tension, and are transported to a subsequent surface treatment device (not shown),
It is sent to a coating device or the like, where surface treatment, coating, etc. are performed uniformly. At this time, since the welded joint 33 of the strip metal plate lO, 22 has little distortion during rolling, local repeated bending that occurs when the distorted portion rolls into contact with the pass roller is reduced. Therefore, even if the band-shaped metal plate is wide, the welded joint 33 has high joint strength and is transported smoothly, so there is no risk of breakage. Further, since there is no need to retreat the coating device from the weld joint 33 as in the conventional case, the weld joint 33 can be uniformly coated.
また、溶接接合部３３の引張り強度は、溶接終了直後に

合強度を更にアップすることができる。Further, the tensile strength of the welded joint 33 is weak immediately after welding is completed, but it recovers when work hardened by the rolling rollers 34 and 36. Therefore, it is particularly effective for band-shaped metal plates such as aluminum whose crystals become coarse due to melting during welding. In addition, even when there is a large difference in the thickness of the strip metal plates or when joining thick strip metal plates, a desired rolling rate can be secured with one rolling movement, and the bonding strength can be increased. It can be further increased.
