Abstract: A technique facilitates construction of a wire-wrapped screen. A wrapping machine is operated with a sensor, e.g. a camera, positioned adjacent the wrapping machine while wire is wrapped to create the wire-wrapped screen. The sensor is used to obtain data on at least one parameter of the wire-wrapped screen during creation of the wire-wrapped screen. Data is provided to a controller in communication with the wrapping machine to improve the quality of the wire-wrapped screen. For example, data from the images obtained via the camera may be provided to the controller which is configured to determine slot width as the wire is wrapped. The controller is then able to provide feedback in real time to the wrapping machine so as to adjust the wrapping machine for maintaining a desired slot width.
