Abstract (en)

At least two weakened lines (1,2) are positioned on the mechanically produced right and left hand side of the letter envelope (5), packet or wrapper. When the envelope is produced, a tear-off strip (6) with double the thickness of paper and at least two weakened lines with one thickness of paper are produced. A second weakened line (3,4) preferably as a bend line is positioned above the first perforation line (1,2). The width of the strip matches the paper thickness. The tear-off strip is positioned preferably 10 millimetres from the inside of the envelope. A hole (8) is punched out of the bottom of the tear-off strip for gripping the inside, coloured, preferably green start (9) to the tear-off strip. The closure flap (12) on the side overlapped by the tear-off strip has a notch (11) or slot.

Abstract (de)

Bei einem Briefumschlag bzw. einer Brieflasche oder -hülle (5) ist eine Aufreißlasche (6) seitlich oder im Verschlußbereich vorgesehen, die in doppelter Papierstärke vorliegt. Die Schwächungslinien (2,3) der Aufreißlasche (6) sind jeweils nur in einer Papierlage angebracht und bestehen in Form von Perforationslinien, wobei innerhalb einer Perforationslinie die Breite der Löcher und/oder der Stege uneinheitlich ausgebildet ist. Durch diese Form der Perforationslinien (2,3) wird eine Aufreißlasche (6) geschaffen, die fest genug ist, um beim postalischen Transport nicht aufzureißen, und beim Öffnen glattkantig, d.h. ohne Querrisse, einreißt. <IMAGE>
