Quick Lock

A Quick Lock (also known as a ball lock friction ring) is used in slitting and rewinding machines where multiple cores need to run on a single shaft with proper tension control. In industries like BOPP film, paper, foil, and laminates, maintaining equal tension across all rolls is a common challenge—this is where the quick lock system becomes very effective. The working principle is based on a ball locking mechanism combined with friction rings. When the core is placed on the shaft, the spring-loaded balls expand and grip the inner diameter of the core. This ensures a firm hold during…Read update
