Abstract: 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.

Abstract: An apparatus includes a transferring arrangement for transferring objects obtained by compression-molding doses of synthetic plastics from a forming arrangement of a forming unit and a supporting arrangement for rotatably supporting the transferring arrangement. In order to avoid blows and/or damage between the transferring arrangement and the forming arrangement, the apparatus includes a moving arrangement connected to the supporting arrangement and configured for moving the transferring arrangement at least between a first operating position nearer the forming unit, in which the transferring arrangement interacts with the forming arrangement to transfer the objects, and a second operating position, in which the transferring arrangement is spaced away from the forming unit so as not to interact with the forming arrangement.

Abstract: An apparatus for forming an object from plastics material includes a forming arrangement having a recess for forming an edge zone of the object, the recess extending around an internal region of the forming arrangement and a conduit cooperating with a piston device to supply the plastics material to the recess, the conduit leading into the internal region into a position contiguous with the recess.

Abstract: An apparatus comprises a molding unit having a punch and a mold cavity movable along a path between an open position in which said punch and said mold cavity are distanced apart from each other to receive a dose of plastics therebetween, and a closed position in which said punch and said mold cavity interact to form an item by pressing said dose, said punch being kept not above said cavity along said path.

Abstract: 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.

Abstract: An apparatus comprises a transfer device rotatable at a speed to transfer a dose of plastics from a supply device to a forming device of said dose, a control device that is suitable for varying said speed in a substantially continuous manner between a minimum value and a maximum value being associated with said transfer device.

Abstract: An apparatus comprises a moulding unit having a punch and a mould cavity movable along a path between an open position in which said punch and said mould cavity are distanced apart from each other to receive a dose of plastics therebetween, and a closed position in which said punch and said mould cavity interact to form an item by pressing said dose, said punch being kept not above said cavity along said path.

Abstract: The mould comprises a punch (10) having an outer surface (11?) arranged to engage the container tubular body (51) as an exact fit, and an end portion (13) projecting axially from the lower end of the cylindrical outer surface (11 ?), and a die (30) arranged to form, in combination with the lower surface (13?) of the punch, a cavity (F) for forming the headpiece (52) of the container; the die (30) has a concave surface (32?) arranged to receive as an exact fit, by axial penetration, the lower end of the cylindrical outer surface (11?) of the punch together with the lower end of the tubular body (51) of the container. The headpiece (52) is formed within the forming cavity (F).
