Abstract: 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.

Abstract: A cutting apparatus is provided for cutting a cap as it travels along an advancement path in an advancement direction. The cutting apparatus includes a spindle movable along the advancement path and rotatable around an axis thereof. The spindle is shaped to interact with the cap and to rotate the cap around the axis. A support moves along the advancement path together with the spindle. The support is shaped to interact with the cap and to retain the cap against the spindle. A cutting device is arranged to form a cut in a side wall of the cap when the spindle reaches a cutting zone provided in the advancement path. The spindle includes a hollow housing shaped to house a cap protrusion to stop rotation of the cap in a preset position with respect to the spindle to orient the cap with respect to the cutting device.

Abstract: A female mould having a forming cavity inside which a concave object can be formed, comprises: an annular forming element extending about an axis and delimiting the forming cavity about said axis; a plate element which delimits the forming cavity transversely to said axis, the plate element having a reference surface extending transversely to said axis externally of the forming cavity; a peripheral annular component at least partially surrounding the annular forming element. The annular forming element abuts against a first portion of the reference surface of the plate element. The peripheral annular component abuts against a second portion of the reference surface of the plate element.

Abstract: A mould for the production of closures with tear-off membrane in a compression moulding machine, comprises: a male die element including a first abutment surface and a female die element movable relative to each other along a moulding orientation. The mould is positionable between a closed configuration, in which the male die element and the female die element are in contact with each other, and an open configuration, in which the male die element and the female die element are spaced apart. The female die element includes: a first block, a second block and a third block, aligned with each other and movable along the moulding orientation; a first spring, interposed between the first block and the second block; a second spring, interposed between the second block and the third block and configured to apply an opening force along the moulding orientation. The first spring is configured to apply a closing force along the moulding orientation to keep the second block and the first block in contact with each other when no other forces are applied.
