ABSTRACT:
A coil spring assembling machine with a row of clamp fittings for clamping coil springs in a row, and first sets of upper and lower coil drive planetary rollers at the infeed end of the row of clamps for infeeding upper and lower helical coils to connect the row of coil springs, at least one of the upper and lower clamps being replaced by a novel combination coil spring clamp and helical coil feeding unit with coil drive planetary rollers within the clamp jaws, for feeding the helical coils, the clamping jaws and feed rollers being simultaneously separable to allow release of the wire coils with release of the springs; a set of clinching units on the rear end of the row of clamps and a set of cutting and clinching units at the infeed end of the row of clamps, these units each having a rotational spindle with laterally offset, axially extending finger projections and an abutment surface for cooperatively clinching the ends of the helical wires, and the cutting and clinching units also having fixed cutoff blades adjacent the rotating spindles to nip off the ends of the helical wires being twisted.
