Abstract: At least one transverse blade (19) is mounted on one end of the body of the pressing device (12) which cyclically acts on the packaging film (1) so as to fix it to an underlying tearing strip (7) which is directed towards the film with an adhesive surface and is supported by a conveyor belt (3), said blade (19) cutting and dividing up to the required dimension the said tearing strip from the continuous tape from which the strip itself is obtained, while the said belt acts as a cutter counter-piece. Auxiliary blades (21, 121) are also mounted laterally and parallel on one end of the body of the pressing device, said blades (21, 121), during the active working phase of the said pressing device, interfering with the edge of the packaging film in order to form, on the latter, incisions located on the sides of the front gripping end of the tearing strip, in order to facilitate tearing of the packaging when the said strip (7) is operated.

Abstract: The base of the machine consists of three modular casings (1, 2, 3) which are aligned with one another and fixed together and inside which the synchronized systems for the various work stations are arranged. The frames of the parallel and vertical-axis belts (C1, C2) which are designed to convey the boxes (B) with a vertical arrangement are supported cantilever-fashion by the base casings, via upturned portal structures (6). The operating stations of the machine are supported by the frames of the belts or by the base casings, such that the box conveying line is free at the bottom so as to allow better cleaning and better inspection. The middle module (2) inserts the product (V) into the boxes.
