  • Coil spring forming and conveying assembly
    Patent number: 6430982
    Abstract: Disclosed herein is a coil spring forming head which is periodically operative to at least partially form coil springs having a plurality of coils and which includes a wire feed advancing mechanism operative to feed the wire which is formed into coil springs, a pitch control mechanism operative to control the diameter of the coils of the coil springs being formed, a diameter control mechanism operative to control the pitch of the coils of the coil springs being formed, and a control including a storage area containing instructions for operation of the wire feed advancing mechanism, the pitch control mechanism, and the diameter control mechanism, a wire feed controller connected to the wire feed advancing mechanism to control operation thereof, a pitch controller connected to the pitch control mechanism to control operation thereof, a diameter controller connected the diameter control mechanism to control operation thereof, and a programmable switching device connected to the wire feed controller, to the pitch
