ABSTRACT:
A machine is disclosed for withdrawing a spiral coil from a prepacked cartridge set of coils and spirally feeding that coil to a coil guide. A stack of sheets having prepunched holes along a side edge thereof is located so that its prepunched holes are aligned with the coil guide. A rotatable drive roller, proximate the coil guide, engages the withdrawn coil and spirally feeds the coil through the coil guide, such that the spirals of the coil sequentially pass through the prepunched holes. After the lead end of the coil has passed through the prepunched holes of the stack of sheets, it is crimped. The drive roller then reverses direction to spirally feed the coil backwards through the coil guide, whereupon the tail end of the coil is crimped. The movements in the machine are designed to vary dependent upon size of the coil.
