    摘要: A mechanism for producing coil springs (10) includes a winding stage (110) for engaging with a wire (20) and deforming the wire (20) to coil windings as the wire (20) moves through the winding stage (110). Further, the mechanism comprises a feed mechanism (120) configured to feed the wire (20) to the winding stage (110). Further, the mechanism comprises a rotary cutter (130). The rotary cutter (130) is configured to cut the deformed wire (20) into portions forming separate coil springs (10) and a blade (135) which is driven for rotation about a stationary rotation axis.
