Zusammenfassung:	A MODIFIED GLUE FLAP (20) OF A FOLDING CARTON BLANK (26) FOR PREVENTING GLUE FROM BEING SQUEEZED OUT DURING THE STEP OF ADHERING THE GLUE FLAP TO THE OPPOSITE END PANEL (12). THE FACE (54) OF THE GLUE FLAP (20) ENGAGED BY THE GLUE BACK-UP WHEEL (34) INCLUDES A PROTRUSION (50) NEAR THE TRAILING EDGE OF THE FLAP. ENGAGEMENT OF THE PROTRUSION (50) BY THE BACK-UP WHEEL (34) CAUSES THE GLUE WHEEL (32) TO SKIP THE TRAILING AREA OF THE FLAP (20). THE ABSENCE OF GLUE IN THIS AREA PREVENTS GLUE FROM BEING SQUEEZED OUT WHEN SEALING PRESSURE IS SUBSEQUENTLY APPLIED TO THE GLUE FLAP (20) AND THE OPPOSITE AND PANEL (12). THE PROTRUSION MAY TAKE THE FROM OF AN EMBOSSED RIDGE (60), FORMING A CHANNEL (62) ON THE OPPOSITE SIDE OF THE PROTRUSION FOR RECEIVING ANY EXCESS GLUE WHICH WOULD HAVE BEEN SQUEEZED OUT. (FIG. 2)
