About the Seminar

The Principles of Web Handling and Winding three-day seminar provides a complete understanding of these key converting fundamentals, covering the materials, equipment, and process factor knowledge to solve any web handling or winding problem.

Web handling principles apply across any roller-transported manufacturing process, helping to improve productivity and reduce waste during production with papers, films, foils, nonwovens, textiles, belts, or any thin, continuous material. The seminar will cover key web handling topics in-depth beginning with material properties, tension control, roller design, nipped processes, web position control, and wrinkle prevention. The winding portion of the session covers all aspects of winding, including the physics and process of winding, roll quality, and winder design, control and operations.

Who Should Attend

This seminar is directed towards technical, production and operations employees of any level with a need to understand the fundamentals of web handling, winding and roll quality.  These principles can be applied across all products, from bath tissue to steel foil.

Attendees will be provided with practical and proven solutions based on best practices and physics to eliminate waste from tension variations, web breaks, bagginess, scratching, misalignment, wrinkles, and roll defects.  If you are looking to optimize, upgrade or replace your web handling equipment, this seminar will review the design options available in tension control, guiding, rollers, and winders, reviewing the mechanics and best practices of each.
