Abstract
A coil advance drive apparatus for connector plate coils is described. The coil advance drive apparatus includes a support structure, a motor coupled to the support structure, at least one elongate coil support member coupled to the support structure, and at least one drive wheel operatively coupled to the motor Each drive wheel is configured to engage the connector plate coil stock. The coil support member includes a plurality of grooves extending longitudinally in one surface of the support member The grooves are configured to receive the pre-punched teeth extending from the connector plate coil stock. The drive wheel includes a plurality of teeth extending from a circumferential surface of the drive wheel. The teeth are configured to engage the open slots in the connector plate coil stock so as to move the coil stock along the support member as the drive wheel rotates. An elongate coil guide cover is coupled to the surface of each coil support member above the grooves. The coil guide cover is configured to at least partially cover the surface of the coil support member to form a channel. The channel is configured to permit the connector plate stock to move along the surface of t…
