However, if there is no resin at the front end (rear end) of the steel strip as in (a), there is no adhesion of the front and back skins by the resin at that part, so bending or wrinkling may occur. Especially, it is likely to occur in the case where the customer or the like transships over a long distance.

For example, as described in (b), 100 to 20 are added to the front and rear ends of the steel strip.
A resin with a width of 00 mm is inserted, and 100 to 200
A 0 mm width resin-free portion is formed, and when welding, the resin-free portion at the tip (rear end) is cut and removed, and then the resin-free portion inside (becomes the front or rear edge after cutting) is overlapped. By welding together, reliable and quick welding can be achieved.

In a commonly used resin coating type, one moving steel strip is continuously coated with a resin by a roll coater or the like. After drying, the other steel strip is moved to the resin surface and pressure-bonded. When the resin is applied, the resin-free portion cuts off the contact with the steel strip of the roll, and the steel strip is When moving 2000 mm, the roll contacts the steel strip and the resin is applied.
