ABSTRACT:
A resin material is fed into a cavity of a mold provided with a movable member adapted to form a tear-line on the resin material and capable of moving toward, and away from, the mold cavity such that when the mold cavity is filled with the resin material and the mold is closed, the movable member is advanced toward the mold cavity thereby obtaining a modular cover provided with a tear-line having a small thickness and a high degree of strength.
