Abstract
An apparatus for forming and assembling spring interiors is provided in which, in the preferred embodiment, adjustable reforming dies adjacent a cutting station lengthen the supporting structure of a bridging portion of the coil band that interconnects coils near the end of the band to compensate for the change of length caused by the cutting of the endmost bridging portion separating spring assemblies. Adjustable dies are also provided to vary the length of the bridging portions when they are initially formed. The coils are interlaced at a lacing station from continuous lacing coil bands.
