Abstract: Forming a cardboard blank includes making two score lines on a cardboard sheet to define a central sector with three portions and two lateral sectors. Four cuts are made in a direction transverse to the score lines to form in one lateral sector a first closing flap and first and second reinforcing flaps and, in the other lateral sector, a second closing flap and third and fourth reinforcing flaps. The first and second closing flaps are folded at respective score lines, and one portion folded to cover a flank of an article on another portion so the first and third reinforcing flaps project. A third portion is folded to cover another flank and an upper article face so the second and fourth reinforcing flaps project. A band folds the first two reinforcing flaps towards the first closing flap and the third and fourth reinforcing flaps towards the second closing flap.

Abstract: Plural articles are arranged in a reusable crate. A cardboard blank is selected in accordance with the volume of the arranged articles. The blank has a first and a second longitudinal score line defining a main portion and a first, a second, a third and a fourth lateral portion, the blank also having a first, a second, a third and a fourth incision that subdivide auxiliary portions into first parts and second parts. The blank and the reusable crate are reciprocally positioned, the bottom of the reusable crate then opened to release the articles onto the blank. The first, second, third and fourth lateral portions are folded towards the articles, with the respective first parts and second parts of the auxiliary portions folding one on another to form respective flaps abutting the group of articles.

Abstract: A machine for wrapping a film to form packs containing single articles includes a conveyor transporting the articles, an aspirated conveyor belt arranged consecutively to the conveyor, a supply station feeding a film and arranging the film with a central part resting on the conveyor belt and with lateral parts projecting from the belt, a frame associated with the conveyor belt and tunnel-conformed for passage of the articles, and folder means for abutting the projecting lateral parts of the film and winding the parts about the tunnel-conformed frame to form a tube of film about the tunnel-conformed frame. A glue device applies glue on one of the two flaps of the film and heat welding and cutting means are activatable for clamping the tube of film and heat-welding and cutting the film to obtain an envelope containing the article.
