Width measurement and monitoring for cotton bale bag manufacturing using contrast sensing

Customer seeking a specialized web width measurement system using contrast sensing. Converting line that manufactures bags for bales of cotton. In the process they coated a web of interlaced extruded green PET material. This coating was clear and extended past the edge of the PET material. The excess coating would then be trimmed off. The customers problem was that the final product, cotton bale bags, depended on the trimmed material. The bags had to fit over a cotton gin/baler. Material width out of specification would result in bags that would not fit the cotton gin/baler and cause problems to our customer's clients.

Roll-2-Roll® Sensors: How it works and what are the applications?

The webinar will cover sensing and measurement technology that are used in Roll-2-Roll® Sensors.

The presentation will cover:

  • the fundamental working principle of the patented fiber optic technology
  • how it differs from the conventional sensors
  • benefits of the fiber optic technology
  • application of the fiber optic sensor technology for sensing and measurement applications such as edge detection, width measurement, registration mark detection, flag detection, void/hole detection, tear detection, etc.

Web Width Measurement and Monitoring

Measure or monitor the web widths in your converting operation regardless of type or width of material. Single sensor application for webs up to 880 mm (34.6 in.) wide or two sensor applications for any web width providing measurement without the need to relocate sensors for most applications. Systems available with options for data recording, simultaneous web guiding, and multiple measurement and monitoring positions.
