ABSTRACT:
A coil spring making machine wherein the advancing rolls for the wire are driven intermittently by a transmission which receives motion from a timing shaft through the medium of a reciprocable input element and two one-way clutches so simultaneously that the rolls rotate in opposite directions (one clockwise, the other counter clockwise). The knife which severs the wire at intervals so as to separate successive coil springs is driven by the timing shaft through the medium of a chain transmission and a link which causes the knife to travel along an endless circular path and to sever the wire while the advancing rolls are at, or close to, a standstill.
