<p>A method of expanding and feeding cartons (4) to a filling line (10); the cartons (4) being made of sheet material, presenting four walls (5, 6) defined by preformed bend lines (7), and being expanded as of an initial flattened configuration wherein each carton (4) is arranged in two superimposed, substantially contacting layers (8, 9), each defined by two adjacent walls (5, 6) of the carton (4); each carton (4) being expanded by rotating each wall (5; 6) of each layer (8; 9) about an arc of over 90 DEG in relation to the other wall (6; 5) of the same layer (8; 9) and into a configuration causing yielding of the bend lines (7); and by only permitting each carton (4) to assume its final parallelepiped-section configuration inside the conveyor pocket (65) of the filling line (10). <IMAGE></p> |
