Abstract: When blanks for producing (cigarette) packs are made in the region of the packaging machine itself, especi- ally by being severed from a web of material (12), the blank production must be matched to the performance of the packaging machine. For severing blanks (10, 11) from a web of material (12) having stampings, perforations, etc. drawing rollers (25, 26) and conveying rollers (33, 34), on the one hand, and tearing rollers (27, 28 and 35, 36) running at a higher speed, on the other hand are used. The blanks (10, 11) are torn off as a result of the difference in the conveying speed. In the simultane- ous processing of two blanks (10, 11), units (23) com- prising two blanks (10, 11) are first severed from the web of material (12) and these are then divided into individual blanks (10, 11) which are conveyed further, especially fed to a folding turret (20).
