CORE-FORMING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a core-forming plate which is easy to be fitted into place before being mounted in the hollow part of a coreless winding and hard to be unlocked after being mounted in the hollow part of the winding. SOLUTION: A tapered protruding hook part 4 is protrudedly provided at one end 2a of a rectangular plate 2 via a constricted part 3 and a hook hole 5 slightly wider than the constricted part 3 is bored inside the other end 2b of the rectangular plate 2. First and second slits 6a and 6b are continuously formed on both sides of that edge 5a of the hook hole 5 which is farther away from the other end 2b of the rectangular plate 2, in such a manner that the slits extend diagonally relative to the width direction of the rectangular plate 2, with the width W6between the tips of the slits being slightly smaller than the maximum width W4of the protruding hook part 4.
