About the seminar
Web Handling II: Understanding Winding and Slitting (WH2) will give you the process knowledge you need to tackle any winding, unwinding, or slitting challenge. WH2 provides the tools to diagnose your existing winding and slitting processes or to start right by using proven best practices for your new products or processes. All things winding are divided into three sections: The Process of Winding uses all the web handling principles of Web Handling I: Understanding Web Handling Systems to build the structure of a wound roll; The Equipment of Winding reviews from simple to complex the many type of winders on the market and where and how they are used; The Solutions of Winding looks at all the ways winding can go wrong and how to avoid them. Slitting focuses on the three conventional slitting methods (razor, crush, and shear), and also includes discussion of alternate slitting methods and slitter operations efficiency. WH2 addresses these topics at all levels, providing rules of thumb and their basis in engineering mechanics. The extensive class notes include hundreds of illustrations to aid understanding of advanced concepts.


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

Learn the definition and best applications of center and surface winding.
Learn five winding benefits of gapped and nipped winding.
Learn what how air enters a wound roll and problems with too little or too much.
Learn how to winding multiple rolls on one shaft and when differential winding is needed.
Learn the causes and remedies to the most common wound roll defects.
Learn how winding contributes to web bagginess and how to minimize it.
Learn the best setup and application of all slitting methods.

Tim Walker has been a process development engineer for over 25 years. While at 3M (as corporate web handling technology leader, leading 3M's web handling process development lab and their corporate process technology management committee) and as an independent consultant, he's worked on wide, high speed operations for commodity products and small, precision manufacturing for magnetic, imaging, electronic, and biomedical applications. He's worked with films of all types, a variety of papers, several different foils, high tech fabrics, nonwovens, and many types of laminates and coated products. For processes, he's worked on continuous coating, pattern coating, printing, continuous laminating, flexible packaging, film-making, paper-making, foil processing, slitter-rewinding, and many varied and amazing web-based processes. A graduate of both the University of Iowa (BS/Mechanical Engineering) and the University of Minnesota (MS in Management of Technology), Tim is currently a highly sought-after consultant, active author for major industry publications, and technical presenter, and is presently on the technical advisory panel for AIMCAL. He is president of TJWalker+Associates Inc, providing services in web-based processes and technology management.
