Halogen-free Flame Retardants for Laminating Adhesives: A Sustainability and Design Perspective Paid Members Public
Presented by Kathryn Cosentino, Alpha Engineered Composites Designing a more sustainable product or process presents a unique technical challenge for engineers to develop solutions that are cost-effective while meeting difficult performance requirements. Rather than considering sustainable development as an isolated initiative, an integrated systems-based approach to technology development with a
How Roller Shape Controls the Lateral Movement of Webs Paid Members Public
Presented by Jerry Brown, Essex Systems Last year, I talked about how shifting, or pivoting a roller produces lateral web motion. This time I will discuss how nonuniform rollers (tapered, concave and convex) produce lateral movement. Once again, we will see that it all comes down to the same thing
Practical Method to Design a Wrinkle Experiment Paid Members Public
Presented by Neal Michal, Converting Expert, LLC Wrinkles are the most common issue that web handlers face. The delivered quality of the web and the wound roll is contingent on the absence of wrinkles. It is common to find troughs and wrinkles in various places on a web process. Wrinkles
Things to Consider for a Successful Inline Slitting Process Paid Members Public
Presented by Joe Connelly, Parkinson Technologies Inc. On the surface, the thoughts of eliminating steps in a converting process to save time and gain efficiency are very appealing. Why wouldn't you want to get shippable products directly off the production line and avoid multiple steps? In many cases,
Web Material Properties: Easy Paths Through the Swamp (but beware of alligators!) Paid Members Public
Presented by Dilwyn Jones, Emral Ltd. The properties of webs are needed for diverse “web handling” activities such as machine specifications, design and upgrade, new and existing product development and manufacture, and troubleshooting breaks and defects – especially using formulae and models. Unfortunately, there is considerable variability hidden behind generic material
Not just Quality Assurance: Reliable Automated Inline Inspection in Battery Cell Production Help Mitigate Risk Paid Members Public
Presented by Luciano Menk, ISRA VISION Battery technology, which is expanding rapidly worldwide, forms the core of several innovative future technologies. In particular, the lithium-ion battery, with its high energy density, has established itself as the leading electricity storage technology in recent years. Without the powerful lithium-ion batteries, there would
A New Look at the Lateral Dynamics of Wide Webs Paid Members Public
Presented by Dilwyn Jones, Emral Ltd Authors: Jerry Brown, Dilwyn Jones and Aravind Seshradi. Dilwyn will be the in-person, conference presenter. Abstract: Until quite recently, there have been no dynamic models that accurately predict lateral behavior for web spans with a length to width ratio (L/W) less than 2.
New Ideas on Web Troughs and Their Consequences Paid Members Public
Presented by Dilwyn Jones, Emral Ltd Troughs are gentle ripples in low and moderate thickness webs between rollers in many R2R machines. If they grow large enough, wrinkles, creases and folds can form on the next roller and cause product damage and waste. This paper outlines a new analysis of
