Principles of Winding and Slitting

The Principles of Winding and Slitting seminar, held at the SpringHill Suites Chicago O'Hare, focuses on the essential processes of winding and slitting in the manufacturing and converting of web materials. The seminar aims to equip participants with fundamental knowledge to ensure the delivery of quality rolls to customers. Attendees will learn about the mechanics of winding and the various technologies involved, alongside significant material properties that influence wound roll structures and their aged through-roll properties. The seminar will define two types of wound roll structures and discuss how they affect product quality.Participants will also address common challenges in the winding and slitting processes. The seminar will cover six different slitting technologies, explaining their application and the fracture mechanics of slitting. Attendees will gain insights into the root causes and recommended solutions for the most prevalent slitting defects, along with information on knife and anvil geometry, metallurgy, and hardness. Strategies for knife regrinding and optimal positioning will be shared, as well as design recommendations for pneumatic conveyance of trim—a necessary component in most slitting and winding processes. Additionally, the seminar will provide a survey of trim winding equipment and present web paths to enhance both winding and slitting efficiency. Three proven methods for collecting trim will also be discussed.This seminar caters to a diverse audience, including lead operators, maintenance personnel, engineers, quality control specialists, product developers, and process designers. Those involved in winding and slitting will find valuable benefits, such as improved understanding of wound roll structures, which can enhance process engineering and quality control. Capital project teams and purchasing departments will also benefit from knowledge on the most suitable winding and slitting technologies for specific web processes. Furthermore, the seminar will address packaging, storage, and shipping strategies to foster supply chain improvements. Safety considerations and best practices will be emphasized throughout the seminar, ensuring that all attendees leave with the practical skills and knowledge necessary to tackle quality and productivity challenges effectively.
