於いて、帯状金属板40の接合部42が塗布装置を通過する
際、塗布装置が盛り上がり部42Aと当接して破損しない
ように塗布装置を待避させなければならない。また、前
記塗布装置を待避させない場合でも、塗布状態が悪くな
り品質不良を発生する。The raised portion 42A of the joint 42 rolled by the welding bead rolling technique projects from the surface of the strip-shaped metal plate 40.
Therefore, in the photosensitive layer coating process in the lithographic printing plate manufacturing process, when the joint portion 42 of the strip-shaped metal plate 40 passes through the coating device, the coating device does not come into contact with the raised portion 42A to be damaged. Must be evacuated. Further, even when the coating device is not retracted, the coating state deteriorates and quality defects occur.

本出願人によって提案されている（特願昭63-108839号
明細書）。Further, when joining strip-shaped metal plates having different plate thicknesses, when it is rolled and contacted with a large number of pass rollers while receiving high tension as in the planographic printing plate manufacturing process, it is required to further increase the strength of the joining portion. It For this reason, a roller with a minute rolling roller part is rolled in the vicinity of the heat-affected zone generated during welding, and the difference in plate thickness between the vicinity of the heat-affected zone rolled by the rolling roller part and the adjacent parts on both sides Has been proposed by the present applicant (Japanese Patent Application No. 63-108839).

分なのでパスローラの転接で局所的な繰り返し曲げを受
け、接合部が短時間で破断するという欠点がある。However, even in the method disclosed in the above-mentioned Japanese Patent Application No. 63-108839, when thin strip-shaped metal plates having different plate thicknesses of 0.10 mm to 0.50 mm are welded by overlapping with each other by 0.5 mm to 2.0 mm,
Since the wall thickness shape of the welded joint differs depending on which plate is facing up, the plate thickness difference between the vicinity of the heat-affected zone rolled by the rolling roller part and the adjacent parts on both sides should be kept within 30%. Even when rolling, if the rolling position of the rolling roller portion is not appropriate, the amount of deformation due to rolling may be insufficient, and there is a problem that the purpose of increasing strength by work hardening, which is a great effect of rolling, cannot be achieved. That is, since the work hardening of the joint portion is insufficient, there is a drawback that the joint portion is locally repeatedly bent by the rolling contact of the pass roller and the joint portion is broken in a short time.
この欠点を解決すべく本出願人は、圧延ローラの圧延ロ

する。However, in the method for joining strip-shaped metal plates disclosed in Japanese Patent Application No. 1-142723, since the rolling roller is engaged in the welded joint, the strip-shaped metal plates to be joined have different plate thicknesses, and the plate thickness is about
In the case of a 0.1 mm thin plate, or when there is a plate thickness difference of 2 times or more, a constriction occurs near the boundary between the welded joint and the strip-shaped metal plate.
また、圧延ローラの押圧力をくびれ発生時より高くする
と、圧延ローラの噛込みが深くなり、前記境界近傍に折
れや亀裂が発生する。If the pressing force of the rolling roller is made higher than that at the time of occurrence of the constriction, the rolling roller is deeply bitten, and breaks or cracks occur near the boundary.
従って、溶接接合部の強度が低下するという問題があ

Fix it while it is in the upper position. Next, above the thickest part of the welded joint 32, which is predicted in advance by the combination of the thicknesses of the strip-shaped metal plates 26, 34 to be joined and the upper and lower sides when superposed,
Rolling roller so that corner 12C of rolling roller 12B is positioned
12 is slightly moved in the axial direction (left and right direction in FIG. 1) to determine the rolling position. The rolling position is the rolling roller unit 12
It may be determined by replacing the position of B with a new rolling roller.

行われる。Next, the cylinder 20 is operated to roll down the rolling roller 12 to press and fix the strip-shaped metal plates 26 and 34. When the motor 18 is subsequently driven, the rotational force of the motor 18 is transmitted to the rolling roller 12 via the gear 24A, the chain 22, and the gear 24B, and the rolling roller portion 12B
The center portion of the material to be rolled, which is sandwiched between the back bar 14 and the back bar 14, is rolled.
従って、被圧延中心部近傍は押さえローラ部12Aで押さ
えられ、被圧延中心部は圧延ローラ部12Bで圧延され
る。Therefore, the vicinity of the rolled central portion is pressed by the pressing roller portion 12A, and the rolled central portion is rolled by the rolling roller portion 12B.

じない。At this time, since the width L of the pressing roller portion 12A is set to be 10 mm or more, preferably 15 mm or more, the surface pressure of the pressing roller portion can be suppressed to be small and the set pressing amount of the rolling roller portion can be maintained. Therefore, the biting into the rolled portion (that is, the welded joint 32) becomes gentle,
No necking, bending, or cracking occurs near the boundary of the welded joint 32.
次に、第１表に示すように圧延ローラ12の押さえローラ
部の幅が異なる４種類の圧延ローラを選定し、それぞれ
の圧延ローラ12で圧延して接合部の強度試験を行った強
度試験結果について述べる。Next, as shown in Table 1, four types of rolling rollers having different widths of the pressing roller portion of the rolling roller 12 were selected, and the strength test results were obtained by rolling with each rolling roller 12 and performing the strength test of the joint portion. I will describe.
強度試験には、厚さ0.24mm幅200mmのアルミ板と厚さ0.1
0mm幅200mmのアルミ板を1.5mm重ね合わせて高周波パル
スアーク溶接で溶接し、この溶接接合部を４種類の圧延
ローラ12で400kgの圧延を行ったものをサンプルとして
使用した。For the strength test, an aluminum plate with a thickness of 0.24 mm and a width of 200 mm and a thickness of 0.1
Aluminum plates having a width of 0 mm and a width of 200 mm were superposed on each other by 1.5 mm, welded by high frequency pulse arc welding, and the welded joint was rolled by 400 kg by four types of rolling rollers 12 and used as a sample.

ローラ部の幅寸法が10mmのとき周回数は32周、サンプル
No.4の押さえローラ部の幅寸法が5mmのとき周回数は15
であった。For the strength test, load 56 kg of tension on these samples and orbit the sample between two rubber rolls (φ600 mm), 22 rubber rolls (φ200 mm) and two rubber rolls (φ180 mm) until cutting or cracking occurs. I decided to see the number of laps. The test results show that, as shown in Table 1, the number of revolutions increased as the width of the pressing roller portion increased. That is, when the width dimension of the pressing roller portion of sample No. 1 is 20.5 mm, the number of turns is 100 or more, and when the width dimension of the holding roller portion of sample No. 2 is 18 mm, the number of turns is 88, sample No. 3 When the width dimension of the pressing roller part is 10 mm, the number of turns is 32, sample
When the width of the No. 4 pressure roller is 5 mm, the number of turns is 15
Met.
このように、押さえローラ部の幅寸法が大きくなると、
圧延時の押さえローラ部の面圧が小さくなるので、溶接
接合部に対する噛込みがゆるやかになり、帯状金属板と
溶接接合部境界にくびれ、折れ、又は亀裂が生じないの
で周回数が増すことが判明した。In this way, when the width of the pressing roller portion increases,
Since the surface pressure of the pressing roller portion during rolling becomes small, the biting into the welded joint becomes gradual, and there are no constrictions, folds, or cracks at the boundary between the band-shaped metal plate and the welded joint, so the number of turns can be increased. found.
