PROBLEM TO BE SOLVED: To provide a winding frame which can be grasped from its both sides and from which a wound coil can be easily removed. SOLUTION: A winding frame for a winding device has a core 40, on which a wire is to be wound, the core 40 is constituted of 4 divided members, and a projection 42b having a wedge surface on its tip end formed in the central part of the core 40 of the members. An extendable rod 80, having a tapered part 82 formed thereto, is inserted into a grip member 30 as a cylindrical member to push the taper part 82 against the wedge surface of the projection 42b and to enlarge the diameter of the core 40, under which conditions the simple wire is wound to form a coil. After the coil is formed, the diameter of the core 40 is reduced, and the coil is removed therefrom. Grasping parts are formed in both ends of a grip member 30, passing through the winding frame to enable grasp of the winding frame 20 from it both sides. |
