Abstract
A machine for transforming zigzag wire to the slotted tubular form ready for use as a binding element comprises means for feeding a strip of zigzag wire longitudinally, means for arresting the feed of each prong of the wire strip as it reaches a shaping station, means for clamping each prong at that station and means at the station for shaping each clamped prong. The shaping means comprises two or more forming tools mounted on rollers which are driven by drive shafts, at least one roller being angularly adjustable relative to its drive shaft. This allows the operation of the forming tools to be synchronized so that symmetrical shaping of the zigzag wire is achieved. The feed means are rotary and means are provided whereby the feed of each prong is arrested for at least one eighth of each revolution of the rotary feed means. The shaping of the zigzag strip is facilitated and improved since the strip is held stationary for a relatively long period of time.
