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.
Claims4
A method for forming an eyewire comprising the steps of:
- transporting a wire to a first bending station and bending the wire in a first direction;
- transporting the wire to a second bending station spaced from said first bending station and bending the wire in a second direction;
- monitoring physical characteristics of the wire and generating monitor signals representative of said physical characteristics;
- shearing a portion of the wire having first and second bends from the rest of the wire;
- controlling the bending and the shearing of the wire in accordance with a predetermined program and the monitoring signals to form an eyewire.
