The core chucks can have a pneumatic, mechanical or pneumo-mechanical expansion mechanism.
Core chucks are mechanical devices designed to securely grip and support the core of a material reel in shaftless winding and unwinding systems. They expand inside the core to provide a firm hold, ensuring stable rotation and reliable material handling during operation.
Unlike expanding shafts, core chucks are typically used in machines with movable frames, allowing them to engage with and release the reel efficiently. They are suitable for handling reels made from various materials and are widely used in paper, plastic, printing, converting, and packaging industries.
