Can You Trust (Web Handling) Equations? Paid Members Public
Presented by David R Roisum, Ph.D., Finishing Technology, Inc. Equations have been used for more than two millennia by mathematicians and scientists alike. Newton’s Laws have been used to predict everything from cannonball trajectories to the orbital mechanics needed to put a man on the moon. Yet, as

The role of new system-level simulation in solving difficult web-handling design problems Paid Members Public
Due to increased demand for consistent quality and faster turnaround times when ordering new web-handling systems, machine designers are turning to simulation to stay ahead of the competition. Simulation models that include dynamical aspects have the advantage over manual calculations...
Closing the web-inspection loop with automatic defect marking Paid Members Public
Automatic web-inspection systems are becoming increasingly more popular. Whether it be surface inspection on an extruder, print inspection on a gravure press or a coatweight gauge on a laminator, web-fed processes can be monitored automatically for out-of-spec conditions.
A Basic Guide to Web Guiding Paid Members Public
Your web’s path may not be where you want it. One remedy is to find and correct the original source of the path upset. This might be as simple as moving the unwinding roll over sideways a bit.
Benefits and challenges of designing and using accumulators in various web-handling operations Paid Members Public
Accumulators benefit many web processes. Zero-speed splicers offer a 99.99% success rate. Accumulators smooth out processes that are required to index. They provide time for a winder operator to start a new roll.
Alternatives to nuclear sensors for on-line web-gauging of weight / thickness measurement Paid Members Public
The traditional method for the on-line measurement of extruded / cast films, extrusion coatings, solution and hot-melt coatings and nonwovens has been the use of one or more Beta Transmission Sensors.
