PCT Engineered Systems LLC of Davenport, Iowa, has received U.S. patent No. 8,106,369 for a new advancement in electron beam processing equipment, called integrated shield technology.
The process uses a roll design that supports the web, while simultaneously serving as a functional part of the EB system's shielding.
According to PCT, combining those two functions greatly simplifies machine design, eliminating the need for a separate enclosure around the roll. It gives precise web handling, and presentation of the substrate to the electron beam, precise temperature control during curing or cross-linking, and other benefits.
PCT's electron beam systems are used on printing presses, coating and laminating lines.
