About the seminar:

Principles of Web Handling will give you the fundamentals and process know-how needed to handle any web handling issue. From exploring the theoretical to understanding practical applications, you will be able to diagnose and treat existing problems and also accurately identify the specifications needed for new webs. You will learn about the critical areas of tension control, web tracking, roller choices and their effects, machine alignment and web defects such as roping, telescoping, and staring. This seminar will address these topics on various levels, from providing basics and rules to remember to examining some of the intricate physics of their behavior. Though theory is included, emphasis is placed on practical problem solving techniques for the plant engineer.

Who should attend:

Anyone working with web machinery will benefit from this unique course. This includes product and process designers, process engineers, quality, sales/service, maintenance and lead operators. The mechanics of web handling are applicable to any web-based product whether paper, film, metals, nonwovens, textiles, or any combination of coated or laminated webs. Understanding web handling is vital to anyone working with webs and web processes, including material suppliers, equipment and component suppliers.

Benefits of attending:

Understand how web wrinkles, start-up waste, slipped rolls, and web breaks all add up to increased costs
Learn to reduce waste in many areas and what are reasonable expectations for waste
Learn to prevent defects like wrinkling, scratching, misalignment, curl, breaks and bagginess
Learn how web and equipment quality create tension variations and understand tension zones
Learn the importance of spreader and anti-wrinkle rollers, choose the best and why most are misused

Course concepts:

Mechanical Behavior of Webs
Necessity of Web Tensioning
Load Cell, Dancer Rollers, or Both
Open-Loop vs. Closed-Loop Control
The Logic of Tension Control for Any Web Process
Causes of Tension Variations
Tension Keys for Laminating

About the instructor:

Chris Watson, President of Watson consulting & Assoc., and former president of Kroenert Corp. a world leader in web handling, coating, and drying technology, began working with web handling issues and helping companies resolve them in 1971. With over 20 years consulting on hundreds of projects dealing with a myriad of issues and materials, Chris continues to help Fortune 500 companies and small startup companies. Chris has lectured for over 30 years at conferences in the US and Europe on web handling technology, coating methods, drying technology, paper physics, and specific issues related to customers’ needs. Realizing that learning curves can be significantly shortened and costly mistakes avoided by consulting with experts who "have been there before", US and foreign companies involved in web coating and converting have attended in-house conference and national conferences to hear Chris. Watson's involvement with web coating technologies goes back to the 1960's. After graduating with a degree in chemistry from The King's College, he was made Project Leader for coated products at Riegel Paper. During this time, he also did graduate work in Polymer Science. Watson has been a successful independent consultant in a wide variety of web related issues including the field of silicone, pressure sensitive, and various web-coating and converting processes for over 25 years. He has advised such firms as Fasson, Coated Products, Mystic Tape, KDP in France, Sterling Coated Products in England, Renker in Germany, OpSec Banknote & High Security in Newcastle UK, Lohja in Finland, and major machine builders in the US.
