ABSTRACT:
A chuck and arbor apparatus for a spring coiling machine implements an accurate alignment of the block wire guide with the feed line guides from the wire supply rolls. The chuck is modified to provide for discrete, axial clamping positions which correspond to selected wire alignment positions. The arbor is preferably D-shaped to establish a repeatable angular orientation in the chuck, and avoid the need to clamp the arbor while clamping the chuck.
