Extrusion technology supplier Davis-Standard (D-S; Pawcatuck, CT) has paired with Scantech Americas to integrate an X-ray transmission scanner for measuring sheet thickness on a proprietary polyethylene terephthalate (PET) system installed this past year. The PET line scanner is used in conjunction with D-S’s EPIC control system, enabling the operator to make adjustments as needed, reportedly reducing start-up time, waste, and material costs.

In addition to D-S sheet applications, Scantech has been working with the company’s Converting Systems Group on cast-, laminated-, and stretch-film applications, as well as non-wovens. Scantech utilizes X-ray transmission to measure sheet or film thickness instead of gamma backscatter or beta ray technology. The online X-ray transmission is non-nuclear and is said to provide accurate measurement for flat-material production processes. Scantech’s measurement systems provide gauging for thickness, weight, material composition, edge reading, web width, surface roughness, defect detection, and moisture, among other properties.

Based in France, Scantech has been manufacturing X-ray systems for 18 years and only recently began selling systems into North and South America. The company claims to be the first to introduce low-energy X-ray sensors for film applications, specifically bi-oriented films. Its U.S. office was established in Lansdowne, VA, and is managed by Rick Roth. —[email protected]
