ABSTRACT:
An eyewinder system 10 has stations 100-108 for straightening, bending, measuring and transporting a wire 11 to form an eyewire 109. A controller 120 controls each station. Using information from tension and length measuring stations 104, 105, the controller 120 can accurately operate the second bending station 107. The eyewire 109 is inspected for accurate bends by an inspection system 140 that compares the bends in the eyewire 109 to predetermined radii of curvature. A base curve bending station 801 has a shuttle 810 and a turntable 830. A wire 820 passing through the shuttle 810 is bent and the head of the wire is held in one direction while the turntable allows the body of the wire to move in a plane transverse to the axis of rotation of the turntable.
