PURPOSE: A winding reel device for a slitter is provided to easily separate the winding reel device from a wound metal band because a ring member stays in the center of the wound metal band to support the metal band so that the metal band cannot be released. CONSTITUTION: A winding reel device for a slitter comprises fixed ring plates(45), expanded pressing pieces(47), extension springs(53), a cam plate(55), a movable ring plate(51), and a sliding plate(49). The fixed ring plates are formed in a ring shape having constant diameter and thickness and are arranged in parallel. Multiple spaces(45b,45c) are arranged between the fixed ring plates. The expanded pressing pieces are installed between the fixed ring plates in the circumferential direction of the fixed ring plates. The expanded pressing pieces are connected by the tension springs. The cam plate is installed inside the expanded pressing pieces. Multiple cam surface parts(55b) are formed on the outer circumference of the cam plate to press and move outward the expanded pressing pieces. |
