Apparatus for the feeding of packaging blanks to a folding unit. In the production of (film) packs, especially for stacks of paper handkerchiefs, blanks are severed from a continuously supplied web of material and fed to a folding member, especially a folding turret (11) for wrapping the paper handkerchiefs and folding the blank (10). When there is a momentary interruption in the feed of articles to be wrapped to the folding turret (11), the production and conveyance of blanks (10) are also to be interrupted. For this purpose, a fixedly located counter knife (22) of a severing station (16) is temporarily movable out of the operative or cutting position, so that, despite the fact that a knife roller (21) with cutting knives (23, 24) continues to run, a severing cut is not made in the stationary web of material (12). For this purpose, a support for the counter knife (22) is equipped with an adjusting mechanism acting in a pulsatory manner. The arrangement and actuation of the knives, especially the movement of the counter knife in order to interrupt the blank production, make it possible to achieve extremely rapid and accurate operating cycles.
