は省略されている。The second welding structure (K) has approximately the same structure as the first welding structure (9), but in order to weld the folded portion of the shorter side of the rectangular cover (1), the cover is covered with an inverted weld (h). The molding table (3) is turned upside down and rotated 90 degrees horizontally by the rotary machine IM (j), so that the previous front and rear sides are oriented in the left and right direction.
It is thermally welded by the same action as the first welding structure (q). However, since the folded portion (17) on the longitudinal side of the rectangular cover (1) has already been welded, the anti-slip relief structure is omitted.
