ABSTRACT:
Web of material consisting of blanks connected to one another by means of residual webs and intended for hinge-lid packs. So that blanks consisting of thin cardboard can be processed as material in web form by a packaging machine, the blanks are connected to one another in the web of material at their free edges by residual webs which are severed in the region of the packaging machine in order to provide the individual blanks necessary for the packaging process. For blanks (14) which are provided with an integrally attached collar blank portion (32) in the region of a pack front wall portion (15) of each blank (14), the web of material (37) is designed so that adjacent blanks are also connected to one another in the region of the collar blank portion (32) by at least one residual web (40), specifically at the free edges of collar side walls (34). Furthermore, residual connecting webs (38, 39) are provided in the web of material in the region of inner side-wall tabs (21) and in the region of inner lid side tabs (29).
