Centre - Surface Winding Paid Members Public
Presented by Michael Schröder, Extrusion Coating Machines Winding of sensitive substrates and laminates in converting machines at the end of the process require the correct winding system in respect of the material behavior and surface characteristic. In the winding process web shifting and wrinkles can easily occur if wrong tension
Vacuum Pull Rolls Design and Applications Paid Members Public
Presented by Kristi Schmidt, Webex, Inc. Vacuum rolls are relatively simple devices with very beneficial characteristics. The use of vacuum rolls is growing with increases in line speeds, quality levels, and safety awareness. Traditional applications include moving a web between coater and dryer and facilitating high speed line operation, but
Applied Research for Vacuum Web Coating: What is Coming Next? Paid Members Public
Presented by Nicolas Schiller, VON ARDENNE GmbH Applied research for vacuum web coating is like a seismographic sensor for new topics that will push forward the industrial application of this technology. The objective of this paper is to concisely present some current R&D topics which show interesting potential

Overspeed in Web Manufacturing and Converting Paid Members Public
Presented by David R. Roisum, Ph.D, Finishing Technologies, Inc. The most common drive control schemes are draw, dancer, load-cell and torque control. In all of these cases the motor pulls directly (or through gearing) on the web and thus directly affects web tension. In all of these cases the
Guidelines for Allowable In-plane Roller Misalignment Using Wrinkling and Web Break Models Paid Members Public
Presented b David R. Roisum, Ph.D. While we have had wrinkling and web break models for a quarter century and the means for precision roller alignment for a half century, no consistent recommendations have been made as to allowable tolerances for roller misalignment. The lack of consistency is not
Vacuum Plasma Deposition of Water and Oil Repellent Nano-coatings Paid Members Public
Presented by Dr. Nicholas Timmer, P2i Several applications of web-based media require a high level of liquid repellency. This may be to provide protection from environmental conditions (for example outdoor clothing, protective coverings, and vent filters used to protect automotive electronics), or to provide protection from specific chemicals (for example
Processes and Equipment for Specialty Web Products Paid Members Public
Presented by Fabiano Rimediotti, Galileo Vacuum Systems This paper will present and discuss specialty applications of vacuum web coating: which are gaining a growing interest from the industry, as a new opportunity of business through diversification. We will describe processes with combined techniques, in particular, patterning and coating with their
