Roll forming is a continuous bending operation in which sheet or strip metal is progressively formed into a desired cross-sectional profile through a series of contoured rolling stands. Barrel type roll forming machines<\/a> are a specialized type of roll former used to produce metal barrels, drums, pails, and other round metal containers.<\/p>\n\n\n\n

Working Process of Barrel Roll Forming<\/h3>\n\n\n\n

The barrel making process starts by loading a coil of thin gauge metal strip into a powered decoiler which feeds the strip through a series of guide boxes into the forming stands. The stands each make a slight increment of the bend using a series of top and bottom contoured rolls. As the strip passes through each stand, it takes on more of the round profile.<\/p>\n\n\n\n

After all stands complete the forming operation, the rolled profile proceeds to a welder which joins the two ends together to create a cylinder. An cutoff device then cuts the cylinder to the required length for the barrels. Finally, a beader unit rolls the edges of the open ends to prepare it for seaming or closure. The finished barrels are then inspected, packed and shipped to customers.<\/p>\n\n\n\n
