Converting webs of pressure-sensitive adhesives (PSAs) presents a variety of challenges. 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.
