The inherent sticky properties of adhesives can be problematic throughout the slitting and rewinding process. Starting at the unwind, adhesives create noise and tension spikes when coming off idler and pull rolls at the master roll. As they move through the web flow, adhesives can stick to equipment, build up on slitting blades and ooze during rewinding if not handled carefully. In addition, converting adhesives often requires adding or removing liners, collecting unlined trim, and adapting machinery to specific customer needs. In order to effectively work with PSAs and produce high-quality finished rolls, specialized equipment is essential. Converting machinery can integrate features such as sound enclosures, non-stick roll coverings, traversing trim winders, blade wicking, tension isolation zones and precise control systems. The web flow can also be designed to minimize contact with exposed adhesives and properly position functions such as liner winding. Choosing the right solution depends on the nature of the web, the type of adhesive, the aggressiveness of the adhesive and the specifications of the finished product.
