摘要： A single continuous length of spring wire is formed into a continuous length spiral or helix which is subsequently folded into a wave configuration for establishing in row form, a plurality of individual spring coils disposed generally parallel one to another. Each coil in the row is connected at its opposite ends to adjacent coils by head or connector end sections. The head or connector end sections are then formed, preferably into a planar Z-shaped configuration such that the formed connector sections at the same ends of the coils are disposed in a common plane normal to the axes of the coils which they interconnect. During forming of the end sections or heads of the coils, each connector section is deformed from a looped three-dimensional attitude into the planar Z-shaped attitude by interengagement with novel forming pins and forming dies.
