CONVEYOR IDLER ROLL ASSEMBLY AND METHOD OF PRODUCING SAME

摘要

An idler roller and the method of making the idler roller. An idler roll cylinder (11) is secured to roll heads (12) mounted with the ends thereof by forming an annular, outwardly opening groove (21) in and around the outer periphery of each roll head facing the inner surface of the roll cylinder. A forming pressure is applied adjacent each end of the roll cylinder to form an inwardly extending annular lock (24) which is pressed into the annular groove. Angularly spaced outwardly opening recesses (32) are provided in the outer periphery of each roll head facing the inner surface of the roll cylinder and receive inwardly projecting lock elements (33) formed in the roll cylinder by the applied forming pressure. The device thus solves the problem of adequately securing a roll cylinder to a roll head.
