Abstract
A spiral overlay having multiple variations, but generically, comprised of wire spirals intermeshed together by connecting rods extending across the conveyor in the transverse direction. Broadly, a first overlay is made up of spirals which may be tapered and afford pitch control by incorporating elongated loops in the spirals to limit the movement of the rods therein. The elongated loops also provide for collapsibility of the spirals relative to one another. A second overlay is made of integral or modular spirals such that the overlay includes upstanding spiral elements on its conveying surface to provide traction and separation of the articles being conveyed.
