Roll-to-Roll Vacuum Deposition of OLEDs For Lighting Application Paid Members Public
Presented by Tomasz Wanski, Fraunhofer Institute for Photonic Microsystems A novel approach has been started to transfer highly efficient small molecule OLED technology into roll-to-roll processing on flexible metal and polymer webs for OLED lighting. The processing line consists of a roll-to-roll vacuum coater for organic materials evaporation, a roll-to-roll
Wrinkling of Foils Paid Members Public
Presented by Timothy J. Walker, TJWalker+Associates, Inc. Kevin A. Cole, Optimation Technology Inc. Aluminum and copper metal webs less than 150 microns thick (6-mils) are considered foils. In many products, thinner foils have cost or weight advantages, but as with nearly any web, thinner means an increased sensitivity to
Wireless Monitoring of Winding Roll Pressures Paid Members Public
Presented by Timothy J. Walker, TJWalker+Associates, Inc. Winding is a dynamic process. The final roll is the product of all that happens from roll start to final cutoff. Nearly all roll measurement methods try to characterize a roll's structure after winding is completed. This is like understanding

Guidelines for Selecting the Best Winding Process Paid Members Public
Presented by R. Duane Smith, Davis-Standard, LLC There is a lot of Science that goes into winding. The TNT winding principles are well established and have been proven and modeled at the Web Handling Research Center at OSU in Stillwater, OK. Yet determining which of these principles, or the proportional
Guidelines for Rolls Used in Web Handling Paid Members Public
Presented by Duane Smith, Davis-Standard, LLC Today’s web producing and converting lines often must handle a wide variety of substrates resulting in wide tension ranges at ever increasing processing speeds. All web handling requires conveying a web straight through a process without distortion or defects such as wrinkles. A
