2 Secial conveyor chains iwis offers an extensive rogram of secial chains for various industrial alications and requirements. While the late chain is being used wherever smooth and reliable conveying through very narrow bends is necessary, the transfer chains are utilized wherever gentle transortation is required. iwis gri chains are alied wherever late and sheet tye materials are drawn in or off, transorted or ositioned. Additional iwis secial conveyor chains: tube and can transort chains, allet transorting chains, side bow chains, leaf chains anti back bend chains and hollow in chains. 57
