This machine is particularly used for bending a metal plate in a cylindrical or conical shape, the plate being one of the main equipments of a vessel, boiler, drum, etc. The machine may be used in the industries of machine building, ship building, petro-chemicals, cement, electrical engines, etc. at ambient temperatures.
In normal temperature conditions, the metal plate is bent to the needed form, but at both ends it is formed a material remnant of straight fragments, a little shorter than half the distance between the pressing roll center and the back rolls. The ends are perforated on another auxiliary equipment for the wished rolling form. This is the main disadvantage of this machine, but, due to the simple construction and operability, this is compensated, and the machine is used with a good efficiency.
