A method of advancing packaging blanks disposed standing upright in a magazine, one after the other, in a file or queue resting against the bottom of the magazine and disposed to be driven forwards through the magazine towards a stop at an outlet end for individual discharge comprises the file or queue of blanks being divided into two pressure zones, a first and forward pressure zone extending from the zone limit between the pressure zones up to the stop and displaying a first mutual pressure between neighboring blanks, as well as a rear second pressure zone displaying a second mutual pressure between neighboring blanks. The first mutual pressure is higher than the second mutual pressure. Another aspect of the disclosure pertains to an apparatus for carrying out advancement of the packaging blanks.
