ABSTRACT:
A coil spring assembly machine for lacing coil springs together to form a coil spring assembly, which machine includes clamping jaws for clamping together portions of adjacent rows of coil springs in at least one of a top and bottom plane of the coil spring assembly, which clamping jaws include dies which cooperate with the end portions of the rows of coil springs to define a helical travel path for helical lacing wires as those lacing wires are moved through the helical travel path. The machine further includes a lacing wire forming and application mechanism for alternatively and selectively supplying lacing wires having two different physical characteristics to that helical travel path.
