PURPOSE:To simplify the structure of a device, to reduce the equipment cost and to improve the dimensional accuracy of a product as well by controlling the corrugated sheet forming force independently by using a load controlling device at the adequate plural positions of the roll for forming. CONSTITUTION:The pressing force of the hydraulic cylinder 9 fitted to the upper part base 7 is given to the rolls 1a, 1b for forming as the waveform forming power via the backup mechanism which is installed at the upper and lower of the rolls 1a, 1b for forming. The backup mechanism installed at the upper and lower is composed of a piece of roll 2 and plurally divided roll 3 and the pressing force is transmitted to the forming roll by the hydraulic cylinder 9, etc. The dimensional accuracy can be increased because of an optional forming power and distribution state being able to be set by this composition.
