The role of new system-level simulation in solving difficult web-handling design problems 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 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 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 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 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.
