れ、現場で簡単に使用することは困難であつた。(Prior art and problems to be solved) When applying waterproofing to the roof of a building using metal cladding, it is necessary to provide rising parts on both sides of the metal cladding and place the metal cladding side by side. This is done by welding the rising part. However, the roof of a building to be waterproofed generally has walls, parapets, etc., and there are places where the metal panels must be bent in the longitudinal direction to stand up. In such a case, if a metal panel material with rising portions on both sides is bent in the longitudinal direction, wavy wrinkles will occur throughout the rising portions of the sides, making welding difficult or impossible and defeating the purpose of waterproofing. I can't reach it. For this reason, conventionally, for example, a hand homer or the like is used to bend the rising part while pressing it as it is, but the hand homer requires many man-hours to perform many repeated processes on each side, and also It is necessary to add a suitable amount of processing at one time, and if it is too large, wrinkles may occur, and the operation requires skill. A bending and forming device using a hydraulic mechanism has also been used, but due to its large size, it is mainly used in factories and is difficult to easily use on site.

The present invention was completed based on the new finding that complete welding is easily possible by seam welding the wrinkle-free portion of the boundary between the rising portion and the second rising portion. The object of the present invention is to provide a method and a folding machine for folding a metal sheet having rising portions on both sides, which is extremely easy and simple compared to conventional methods.
