The crease-lines are on the male side interrupted to provide a longitudinal seal strip to an edge of each blank to become. The cardboard web is in a limited area of such an interruption intentionally and positively lifted and supported from the side of a female crease die to a level in between being in line with to being above an outermost surface of a female crease die roller of the machine.
