Web Handling Best Practices – Manchester UK Seminar
To be held 21-22 May 2013 at the Hilton Manchester Airport, the Principles of Web Handling two-day training course 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
Do you work with a web? Do you manage people who run web handling machines? Do you sell or develop web products? Have you ever had a question about why the web is behaving the way it is? Do you get a different behavior from one day to the next but have no idea why? Would you like to speed up your operation without increasing waste? Are you having difficulty troubleshooting wrinkling issues? Do you need to reduce your waste? If so, this seminar is for you. Product and process designers, process engineers, QA/QC, sales and service personnel, and maintenance and lead operators are strong candidates for this seminar. Material, equipment and component suppliers can also benefit. The principles taught in this seminar are applicable to any web-based product whether paper, film, metals, nonwovens, textiles, or any combination of coated or laminated webs.
- Defining a web and a look at what moves it
- Common web defects
- The all important control: pulling the web or tensioning
- The importance of rollers
- Measuring tension then controlling it (load cells & dancers)
- Holding the web to a straight path
- Traction requirements of idlers and driven rollers
- The “why’s” and “how’s” of tension control
- Can you control the tension variations in your process?
- Laminating basics
- Critical machine alignment: the easy way and the hard way
- The worst defect in web handling: wrinkling
- Wrinkling causes and remedies
- How to diagnose wrinkles
- Spreading and anti-wrinkle rollers
- Measuring and modeling nipped rollers
- Air floatation and turn bars
- Web tracking rules
- Control systems
- Winding profiles
- Specifying rollers
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
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 customer 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.
