ABSTRACT:
A node roller combination method and apparatus has a node roller and a backing roller between which sheet material is passed. The node roller has a series of ring shaped circumferential nodes at spaced intervals across the material. The nodes press the sheet material into the backing roller to form a series of small radius small angle bends between flat segments and repetitions of succeeding stages of node and backing rollers forming bends between previous bends that provide a curved shape that gives the appearance of a large radius bend without the tendency to spring back to an original shape.
