Abstract (en)
[origin: WO2019092404A1] A spring forming apparatus is shown generally at (200), in which metal wire (220) is fed from a supply (not shown) by feed rollers (230), via irregularity-effecting rollers (240) to a forming station (250). The forming station comprises a first deflector (260) and a second deflector (270). When the spring S is complete, it separates automatically from the rest of the wire (220) due to the presence of an irregularity (280), without the need for a cutter device.
