The present invention relates to a method in the advancement of packaging blanks (2) disposed standing upright in a magazine (1), one after the other, in a file or queue resting against the bottom (3) of the magazine and disposed to be driven forwards through the magazine (1) towards a stop (6) at an outlet end for individual discharge. It comprises the steps that the file or queue of blanks is divided into two pressure zones, a first and forward pressure zone (12) extending from the zone limit between the pressure zones up to the stop and displaying a first mutual pressure between neighbouring blanks (2), as well as a rear second pressure zone (13) displaying a second mutual pressure between neighbouring blanks (2), and that said first mutual pressure is higher than said second mutual pressure. The invention also relates to an apparatus for carrying out the method.
