A cap for a container is formed so that the cap has a top plate and a circular sidewall. Two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connecting to one surface of the top plate forming a closed end, and another periphery of the circular sidewall at an opposite side of the closed end forms an opened end. Incisions are in the circular sidewall. The incisions form a ring member located at the opened end of the cap separated from a main body of the cap by a first incision and a second incision between the opened end of the main body and the ring member.

A cutting apparatus and a cutting device are disclosed including a modular insert arranged at least partially in a housing cavity, in which the modular insert includes a cutting element for performing a vertical or oblique cut and an abutting block which is interchangeable and couplable with the cutting element to fix a total dimension of the modular insert, in which an abutting face of the abutting block abuts on a back wall of the housing cavity so that a rear end of the cutting element is spaced away from the back wall. An assembly method is disclosed for assembling the aforesaid device including the steps of providing a plurality of interchangeable abutting blocks and of choosing an abutting block between the plurality of interchangeable abutting blocks on the basis of a desired total dimension of the modular insert.

A cutting apparatus for cutting a cap provided with a cup body and having a base wall, a side wall and a protrusion projecting from the side wall of the cap outside the cap, includes: an advancement path travelable by the cap along an advancement direction, a spindle movable along the advancement path and rotatable around an axis thereof, the spindle being shaped to interact with the cap and to rotate the cap (10; 110; 210) around the axis, a support movable along the advancement path together with the spindle, said support being shaped to interact with the cap and to retain the cap against the spindle, a cutting device arranged for making a cut in the side wall of the cap when the spindle reaches a cutting zone provided in the advancement path,
in which the spindle includes a hollow housing shaped to house the protrusion so as to stop in use a rotation of the cap in a preset position with respect to the spindle so as to orient the cap with respect to the cutting device.

A cutting apparatus and method are disclosed to form the preferential fracture line of a capsule for closing containers, in which a rotating carousel carries a plurality of spindles, each of which can engage a respective capsule that is rolled against a contact surface made of ultra-high molecular weight polyethylene, and in which a fixed blade with a circular sector performs the cut on the rolling capsule, the cutting apparatus and method being applicable to capsules of different dimensions and types.
