Abstract:
A method of manufacturing cigarette packs of the hinge-lid type by folding cardboard blanks (10) in a packaging machine (22), the blanks (10) being prepared by stamping and having folding tabs defined by punched-out lines (18) and by folding lines (16, 17) formed by embossing, said method comprising the steps of:a) positioning, in a region of the packaging machine, an elongated web (19) made of cardboard and wound up as a reel (21);b) applying to the web (19), on one side thereof, printing (29) corresponding to an outer design of a hinge-lid pack, during formation of blanks (10) which are lying adjacent to one another in the web and which have a longitudinal dimension extending transversely to the elongated web (19);c) applying the printing (29) so that it is oriented transversely to the longitudinal direction of the elongated web (19) within each blank, such that printings for a box part (11) and a lid part (12) of each blank follow one another in the transverse direction of the web (19);d) feeding the web (19) in a continuous conveying motion to one of plural blank-forming units (31) of the packaging machine (22);e) within the blank-forming unit (31), first embossing the web (19) to form plural folding lines (16, 17) of the blanks (10) to be produced, said plural folding lines comprising longitudinal folding lines (16) running transverse to the longitudinal direction of the web (19) and transverse folding lines (17) running in the direction of the web (19);f) then, making punched-out lines (18) in the web (19) to form folding tabs and, at the same time, a transverse severing cut (32) for separating each blank (10) from the web (19);g) choosing the web (19) to be greater in width than the longitudinal dimension of the blanks (10), producing contours of the blanks (10) on both longitudinal edges of the web (19) by contoured longitudinal cuts (34, 35), and cutting off corresponding residual pieces (61, 62) of the web while the punched-out lines (18) are made;h) then, removing the blanks (10), from the web;i) feeding the removed blanks (10) to a collecting station within which piles (23) of blanks are formed from successively incoming blanks (10); andj) then, feeding the piles (23) of blanks to the packaging machine (22).
