The present invention relates to a method of manufacturing a modular air bag cover provided with a grooved tearline along which the cover is teared to allow the air bag to develop. The method according to the present invention is characterized in that a resin material is fed into the cavity of a mold provided with a movable member adapted to form a tearline 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. |
