A spring interior forming method and apparatus provides a spring interior assembler and a coil row transfer station upstream of the assembler having at least one conveyer extending therethrough. A coil former is provided at an upstream end of the conveyor and is operated through a plurality of cycles, each to feed one spring coil onto the conveyor. In one embodiment, a single former is provided with a single conveyor extending therefrom through the transfer station. In a second embodiment, two such coiler-conveyor combinations is provided. In a third embodiment, one conveyor through the transfer station is provided with two coilers, each having a feeder preferably in the form of a conveyor, that selectively feed spring coils, which may be of different types, to a cross-over station for feed onto the transfer station conveyor. In a fourth embodiment, each coiler accumulates springs at its output while awaiting queing by the cross-over station. Between consecutive cycles of the feeding of a spring onto the transfer conveyor, a stepper motor or other servo-type motor advances the conveyor a programmed distance, thereby providing the capability for obtaining different programmed spacings between coils on the rows presented by the transfer conveyor to the transfer station.
