Abstract

A method for molding rubber into articles, in which the unvulcanized rubber is placed in a mold cavity defined on the one hand, by said article, and on the other hand, by means of closed side walls and a movable mold member, located inside of said side wall means, opposite to said articles, characterized in that said movable mold member having a peripheral rim in sliding contact with said side wall means and a substantially continuous peripherally arranged recessed portion adjacent to said rim on the side surface thereof, in the direction away from said article, is advanced within said side wall means towards the article until the rubber spreads against said article and until the rubber escapes between said flange and said wall means lateral to partially fill at least the space defined by said recessed portion; said rubber is allowed to partially harden at least and begin to vulcanize to said article, while a peripherally extending weakened region is formed with said flange in the rubber surrounding said flange; said movable mold member is retracted in said direction away from said article while dragging with it the portion of said rubber that is in said space defined by said recessed portion, in order to tear said portion of said rubber from the rest of the rubber along said weakened region.
