Abstract
A core-coupling unit includes a top cover and a bottom cover each having a U-shape. The core-coupling unit clamps a pair of core members in a coupled state with the top cover and the bottom cover being coupled with each other. The top cover is provided with apertures formed in respective legs of the top cover, and the bottom cover is provided with projections formed on respective legs of the bottom cover, the projections mating with the apertures so as to prevent removal. Play-gaps are provided between each projection and respective front and rear edges of the aperture. Lips are provided on the covers for maintaining the positions of the core members in the backward and forward directions. The top and bottom covers are moved backward and forward relative to each other while the core members are clamped, whereby the core members are moved together with the respective top and bottom covers, thereby performing core-rubbing.
