Web handling best practices – Manchester UK seminar
To be held 20-21 May 2014 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.
• 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

Timothy J. Walker is an internationally recognized expert and consultant in web handling and winding processes and president of TJWalker and Associates, Inc. He specializes in design, development, and education for handling and winding web products, helping many clients in their development of thinner, wider, faster, more precise, or more integrated processing.
Tim works with clients to expand their business or improve profits by enabling difficult or marginal quality materials or by reducing waste from wrinkling, scratching, curl, bagginess, roll quality, and tension/nip variations. He has consulted with over 150 client companies and taught web handling to over 4000 students.
Tim works with any web process, from traditional converting, printing, and die cutting of film and paper product to other industries where webs play a key role, including flexible electronics, battery films/foils, optical films, medical/pharmaceutical, graphics, construction materials, and steel/foil.
Before starting his own company, TJWA Inc. in 1999, Tim was with 3M Company for 17 years, working in their polyester film and corporate web handling technology groups. Prior to leaving 3M, he was a process development specialist, leading the web handling development planning and education across all divisions and serving as the 3M representative to the Oklahoma State.
He has a BS in Mechanical Engineering from the University of Iowa and an MS in Management of Technology from the University of Minnesota. Tim resides with his wife and three children in St. Paul, MN.
