ABSTRACT:
During the wrapping of articles (stack 10) in blanks (11), the latter are severed from a web of material (21) and fed to a folding turret (13). When the delivery of articles (10) to be wrapped is interrupted, the severing of blanks (11) and the feeding of these to the folding turret (13) are also interrupted. For this pupose, while knife rollers (26, 29) continue to run, the web of material (21) is stopped after it has been conveyed beyond the severing point an amount corresponding to a follow-up portion (44). The knives (severing knives 30) of the knife rollers (26, 29) rotating further are moved out of their cutting position.
