摘要：Method for embossing fold lines into fold box blanks (13), wherein a conveyor belt (20) passes the fold box blanks (13) between an embossing tool (30) and a countertool (31), the plastication heat is supplied to the fold box blanks (13) by guiding the heated lower tool (30) toward the conveyor belt (20), whereupon the embossing of the fold line takes place, and wherein, after the embossing has taken place, the conveyor belt (20) travels on with the embossed fold box blanks (13) which remain on the conveyor belt (20) until cooled down, whereupon they can be removed from the conveyor belt (20). The embossing of the fold lines into the fold box blanks (13) can take place either from above or from below through the conveyor belt (20) (Fig. 1). <IMAGE>
