Abstract
Twist pins having bulges are fabricated from helically coiled stranded wire. Wire is advanced from a source such as a spool to create slack wire configuration, and wire is then advanced from the slack wire configuration to a position where each bulge is formed. Each bulge is formed by gripping the wire in two spaced apart locations and rotating the wire in an anti-helical direction in a single continuous relative revolution to untwist the strands and form the bulge. The wire is thereafter advanced to the position of the next bulge or the position where the wire will be severed to release the fabricated twist pin. The severed fabricated twist pin is conveyed through a flow of gas in a delivery tube into a receptacle of a cassette where the twist pin is stored until used. The cassette is automatically moved to position an occupied receptacle to receive each newly fabricated twist pin.
