摘要： A mold is provided for forming caps for closing containers by compression molding doses of plastic material, where a bottom wall of the cap, or at least one portion of the bottom wall is very thin. The mold includes two half-molds axially movable towards each other which assume an end closed position without a dose. A tubular element is slidable around the second half-mold and partially defines the cavity. The tubular element contacts an axial abutment of the first half-mold at one side and an axial end stop of the second half-mold at the other side to prevent hard contact between the half-molds.

摘要： A method of embossing a crown cap comprises the steps of: detecting a pre-printed drawing on the bottom of the crown cap, varying the angular positioning of the crown cap so as to position the drawing according to a preset positioning, and impressing a raised/recessed pictogram on the bottom of the crown cap. The pre-printed drawing and the embossed pictogram will have a desired reciprocal position.

摘要： In a cutting apparatus a rotating carousel conveys caps made of synthetic plastic material to a fixed blade having the shape of a circumferential arc. The caps are rotated about themselves by spindles. The blade cuts an annular weakening line to form the tamperproof ring of the cap. The carousel has an emitter and a laser receiver that cooperate to detect the presence or absence of the cutting edge of the fixed blade. The apparatus ensures good cutting quality.
