ABSTRACT:
A ring former and cutoff utilizes a continuous ring former which causes the stock to assume the form of a helix having a number of turns. The leading end of the helix after forming a plurality of free turns passes through a drive roll set, through a stationary cutoff die and into a sizing hoop of larger diameter than those in the turns of the helix. The free end of the helix to expand within the sizing hoop. Sensors detect the expansion to energize the cutoff at the die to sever a turn of the helix with the momentary halt of the stock at the die causing the helix between the cutoff and former to expand or unwind. When the severed end of the helix is removed or falls free, the drive roll set again drives the new leading end of the helix through the cutoff die at a speed sufficient to return or wind the helix to its original condition.
