ABSTRACT:
A wire winding blade extends through spiral outfeed guide members and receives spring-like unannealed wire from a source drawn by rotation of the winding blade; the wire from the source first passes through tensioning means then over an infeed guide pulley which guides it into a linear guide member having a bore slightly in excess of the wire diameter from which the wire passes over a small diameter idler roller sheave which imparts a back bend to the wire which is then fed into the slot of the spiral wire guide means where it is bent in a reverse manner about the winding blade.
