Abstract

PURPOSE: To obtain a high polymer product free from local deviation of the intermediate reinforcing layer from a sheet-shaped high polymer material having an intermediate reinforcing layer by rolling the portion molded with the product forming section of a mold after the portion molded with the burr forming section of the die.
CONSTITUTION: A mold is composed of a male mold 11 and a female mold 10 in which a product forming section 12 having a bead forming part 14 on the circumference thereof and a burr forming section 13 are properly arranged. The mold is so constructed that the distance between the product forming sections 12 of the two molds are slightly less than the thickness of the high polymer material 4 while the distance between the burr forming sections 13 of the two molds ranges from 1/5W 1/2 as large as that of between the burr forming sections 13 thereof when the male mold 11 and the female mold 10 are closed. A high polymer material having an intermediate reinforcing layer 2 is set into the female mold 10 heated and then, drawn toward the female mold 10 with the male mold 11 thus heated in such a manner that the material existing in the burr forming section 13 flows to the circumference of the burr forming section 13 and the bead forming part 14 through stretching. With further drawing of the male mold 11, the mold is closed completely whereby the material existing in the product forming section 12 are stretched to mold.
