Patent issued for integrated Roll Shield design




PCT is proud to announce that US Patent 8,106,369 has been issued for a new advancement in Electron Beam (EB) processing equipment - Integrated Shield Roll technology. This technology utilizes an innovative roll design that supports the web while simultaneously serving as a functional part of the EB system’s shielding. Combining these functions greatly simplifies the machine design and eliminates the need for a separate enclosure around the roll. The advantages of this design include: 1) precise web handling and presentation of the substrate to the electron beam, 2) precise temperature control during the curing or cross-linking process, 3) compact machine footprint compatible with low web pass heights, 4) simplified cleaning and maintenance, 5) reduced nitrogen interting costs, and 6) enhanced process integration by the addition of nips, coating heads, or casting directly on the exposed roll surface. This technology is currently being deployed over the full range of PCT’s BroadBeam EB product line.
