Method and apparatus for forming a row of spring coils from a continuous length of wire

Abstract From the Canadian patent

Abstract of the Disclosure, 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 …
