ABSTRACT:
A board blank for producing a packaging corner has at least three parallel strips which are arranged next to one another and are connected to one another. A central strip of the three strips is connected to a first outer strip of the three strips by grooved portions along a first line. Cuts are made between the central strip and the first outer strip between the grooved portions. A profile of the cuts deviates from the first line in a manner extending into the central strip. The central strip and a second outer strip of the three strips are connected by a score in the board along a second line.
