ABSTRACT:
A method for precision aligning of carton blanks having discrete fold lines in the manufacture of product display packages utilizes projecting alignment pins and transparent window blanks having laterally opposed notches. The alignment pins are arranged about the periphery of a carton blank having discrete fold lines and adjacent the inner edges of a formed opening for registration of the carton blank. The transparent window blank, having its pair of opposed notches in alignment with a fold line, is disposed in overlapping relationship over the opening of the carton blank, such that the alignment pins are received within the notches. The cooperation of the alignment pins and notches effectively provides precision alignment of the transparent window blank with the carton blank, for example, with respect to their fold lines and the like.
