Abstract
Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be 'dovetailed' into one another. A packing container blank is provided with partly straight, parallel lateral edges (11,12), and partly transverse edges (11,12) which are indented according to a regular pattern which is repeated over the width of the blank. As a result of the indentations, the edges of the blanks too can be formed without wastage.
