Abstract
An apparatus includes means for feeding a wire from a fixed outlet against a coiling surface having a variable location in relation to the fixed outlet. The fixed outlet directs the wire in a path and the wire is deflected from the path by the coiling surface to bend the wire. The wire is monitored and output signals indicative of a physical characteristic of the deflected wire are generated. A controller receives the signals and generates control signals as a function thereof. An actuator, responsive to the control signals, adjusts the location of the coiling surface such that the physical characteristics are substantially uniformly maintained during the forming of the spring.
