A multi-cavity mould (1) comprising:—an upper tool (11) and a lower tool (12) arranged in a cooperating manner; characterized in that the upper tool (11) comprises a knife pressure box (13) comprising:—a horizontal top plate (131);—first and second end plates (132) and first and second side plates (133) extending orthogonally downwardly from a lower surface of the plate (131); the plates (132, 133) are connected such that the plate (131) and the plates (132, 133) form a downwardly open rectangular parallelepiped enclosure; the plates (132, 133) are made from tool steel with a thickness (t) from 6.35-10 mm and a cutting surface (130) defined along an orthogonally downwardly projecting end of plates (132, 133) wherein—the surface (130) has a substantially V-shaped profile comprising a micro flat face (M) with a width from 0.02-0.1 mm and is positioned such that when the pressure box (13) is pressed against the sheet (3), the surface (130) partially penetrates the sheet (3) in order to form a seal around the pressure box (13) by pressing a zone of the sheet (3) which was partially trimmed and situated inside the enclosure against the surface (130).

A knife is arranged for being fitted in a cutting apparatus for obtaining incision lines and notches on a cap made of plastics intended for closing a container and is suitable for making notches and incisions on a side wall of the cap when the cap, by rotating around its own rotation axis, is moved along a path for interacting with the knife in an advancement direction; the knife includes an arrangement of cutting edges that project from a peripheral region of the knife, the arrangement of cutting edges including: an opening formation part that extends parallel to a horizontal plane orthogonal to the rotation axis, the at least one opening formation part being arranged for making at least one circumferential notch on the side wall at a first height on a vertical axis that is substantially parallel to the rotation axis to define a tamper-evident ring and a main body in the cap; at least one connection formation part that occupies a region extending between the first quote and a second height that is greater than the first height on the vertical axis, the connection formation part being arranged for making at least one notch on the side wall to determine at least one connection portion connecting the tamper-evident ring and the main body;
wherein the knife consists of a single piece, the arrangement of cutting edges being obtained in the single piece.

Packaging apparatuses for loading and sealing products into a web of interconnected bags, and methods of using them, are provided. In one aspect, the packaging apparatus includes an intermittently advancing web conveyor that also indexes vertically to facilitate stacked loading of products into the bags. In another aspect, the packaging apparatus includes a dividing seal station that applies a center seal dividing the bag into separate sealed subcompartments, some of the bag contents being distributed to each compartment, such as one of two trays to each subcompartment. To facilitate distribution of contents and even sealing, the dividing seal station may include a dividing sealer lower support that oscillates vertically to promote settling of contents and gases in the bag before applying a dividing seal.

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.
