Abstract
An improved rotary rolling or bead rolling machine capable of placing beads, crimps, flanges, turns, burrs, elbows, slits, offsets, collars, flats, or other deformations in sheet material. The machine provides a foot operated roller force and motor control and allows an operator to utilize two hands to manipulate the sheet material placed between the rollers. The machine utilizes an air spring or air-stroke actuator to provide substantial roller force in a small volume. The machine further provides roller adjustability whereby a roller may be displaced relative to another roller.
