Abstract

PURPOSE: To join the overlapping part of a formed part and a rising part, and to reduce the man-hour requirement, by proceeding the work as follows; a flat sheet is bent into an angle shape, the bending position of the rising part being bent into the right angle is cut into an L-cut, and a part along this L-cut is pushed up to form a stepped part.
CONSTITUTION: An L-cut is made in the flat sheet 5 along the bending lines 6, 7 by the use of a die for the exclusive use, and a part equal to thickness of sheet from the bending line 9 is pushed up to form a stepped part. Next, the flat sheet 5 is bent into an L-shape along the bending line 6, and further is bent in the right angle along the bending line 7 so as to rise up. After that, the overlapping part of the stepped part and the flat part is joined to finish the frame of the framed box.
