ABSTRACT:
A method of expanding and feeding cartons to a filling line; the cartons being made of sheet material, presenting four walls defined by preformed bend lines, and being expanded as of an initial flattened configuration wherein each carton is arranged in two superimposed, substantially contacting layers, each defined by two adjacent walls of the carton; each carton being expanded by rotating each wall of each layer about an arc of over 90.degree. in relation to the other wall of the same layer and into a configuration causing yielding of the bend lines; and by only permitting each carton to assume its final parallelepiped-section configuration inside the conveyor pocket of the filling line.
