DUAL LACING WIRE MECHANISM FOR A COIL SPRING ASSEMBLY MACHINE

摘要

A coil spring assembly machine (10') for lacing coil springs (16') together to form a coil spring assembly (20'), 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 (26') 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 (44', 64) for alternatively and selectively supplying lacing wires (28a, 28') having two different physical characteristics to that helical travel path.
