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.

[ We claim:] [1.] A method of expanding and feeding cartons to a pocket conveyor; the cartons being made of sheet material, comprising four walls defined by preformed bend lines, and being expanded to a final parallelogram-section configuration, in which each of adjacent walls of said walls is arranged at right angles, from of an initial flattened configuration wherein each of said cartons is arranged in two superimposed, substantially contacting layers which are integral with each other along two first bend lines of said bend lines, and are each defined by two adjacent walls of said walls of the carton integral with each other along a respective second bend line of said bend lines; comprising initially expanding each said carton to a yield configuration which is reached by rotating each of said walls of each of said layers about an arc of over 90.degree. in relation to the other wall of the same layer past said final configuration, to cause a yielding of the bend lines; maintaining each carton in the yield configuration until the carton is fed into a respective pocket on said pocket conveyor; and allowing each carton to spring back from said yield configuration to said final configuration only within said pocket.
