Abstract
A straight wire length is bent against a mandrel into an obtuse V-shape and then into a C-shape at a first station, and against another mandrel into an oval shape at a second station. When making the V-shape bend the leading edge of the wire length is thereby contained against perpendicular movement. The wire length is then bent into a C-shape and when it is moved from the first station to the second station the stop is pivoted against the force of the spring by a bar transforming the V-shape to the C-shape. When the emerging C-shaped link clears the support surface of the stop element, the spring returns the stop element to its initial position in the first bending station, against a stop. The surface of the stop element contacting the stop may serve as an electrical contact for process control. Also, in the first station the vertical space between the straight wire length and the leading edge of the mandrel is greater than the diameter of the wire, thus clearing the path of the feed of the straight wire length into the first station for high productivity at least during the transport of the C-shaped wire piece from the first station to the second station.
