Abstract
An apparatus for manufacturing a welded pipe. The apparatus includes a cage or cluster roller molding system. In either case, a rotary axis of each roller is slanted counterclockwise or clockwise with respect to a manufacturing line direction of the apparatus. The adjustable positioning of the rotary axis reduces vertical slip caused when the strip of material passes along the contact surface of the roller.
