Abstract
A device that can individually separate thin nested metallic diaphragms prior to welding same to form bellows is disclosed. The device uses a threaded rod (16) which is tilted upwardly with respect to the horizontal. One end of threaded rod (16) is received through the inside diameter of a stack (32) of nested diaphragms while the other end thereof is received in a collet (18) attached to a gear motor (20). As threaded rod (16) is rotated by gear motor (20), each diaphragm (10) is carried in its own groove provided by the threads on the threaded rod (16) to the free end thereof where one diaphragm is discharged for each revolution of the threaded rod (16).
