Abstract An apparatus for cutting a paper web, in particular for the production of liquid packs, has a movable punch which can be pressed against a counter-plate and which has a circular blade at its tip. In accordance with the invention, to permit the desired cut to be made in the packaging material to the desired depth, using simple means, the punch has a rotationally driven cutter head. Due to the rotary movement of the punch or the blade-forming edge at the tip of the punch, the blade is no longer merely pressed into the paper web, as in previously known punching apparatuses, but in accordance with the invention it is rotated perpendicularly to the pressing movement, giving a cutting effect as when using a knife.
