PURPOSE:To perform the steel wire inserting work easily, by a method wherein partitioning thin sheets are inserted within a mold in conformity with the core shape so as to partition the mold into small chambers, steel wires coated with epoxy resin are inserted, and then the partitioning thin sheets are drawn out. CONSTITUTION:An outside mold 3 and an inside mold 5 are put on a base 4 and partitioning thin sheets 6 are radially inserted in an annular recess formed therebetween so that a folding portion 62 is contacted to the inside mold and a side edge 63 is contacted to inner wall of the outside mold. Since the folding portion 62 of the partitioning thin plate 6 is perpendicular to a bottom edge 61, bottom edges constitute a flat plane and stand for themselves within the mold so as to partition the annular recess into a plurality of small chambers 3a, 3b, 3c.... Steel wires 1 coated with epoxy resin are inserted in each small chamber. When the steel wires of about required number are distributed and inserted to full volume, the partitioning thin sheets 6 are drawn out and residual steel wire 1 is inserted for replenishiment. |
