Method and machine for packing a product

A machine for packing a product by means of a flat blank (4) comprising a central portion (10) having first lateral wings (11);

• and two opposite lateral portions (12), each having second lateral wings (13);
• the machine (1) comprising forming means (18, 19) for resting said product (2) on said central portion (10) to define an assembly (8) defined by the product (2) and the blank (4);
• a first conveyor (20) for feeding said assembly (8) along a packing path (P1) with said central portion (10) and said lateral portions (12) aligned with one another in a direction (21) crosswise to the packing path (P1);
• at least one second conveyor (55) for feeding along said packing path (P1), and in time with said assembly (8), at least one folding body (23) having a first (56) and a second (57) folding edge differently inclined with respect to each other;
• folding means (24) for folding said lateral portions (12) through 90° onto the product (2);
• and control means (59) for rotating said folding body (23) about an axis (58) crosswise to said packing path (P1);
• said control means (59) being such as to successively effect a first and a second rotation of said folding body (23) about said axis (58) wherein, during the first rotation, the second folding edge (57) folds said second lateral wings (13) substantially through 90°, and the first folding edge (56) folds said first lateral wing (11) to a given angle (A) with respect to the second lateral wings (13);
• and wherein, during said second rotation, the first folding edge (56) completes 90° folding of the first lateral wing (11).
