ABSTRACT:
A web of tubular or semi-tubular film is provided with transversely extending weld seams and lines of perforations to define bag sections and it is cooled while being fed to a severing and stacking station where the leading bag section is severed from the film and deposited on a stack of bag sections. The successively severed bag sections are deposited on a lowerable support up to a desired stacking height and they are clamped to the support alternately by a vertically reciprocatable punch and by being pressed against a clamping bar disposed above the support. Each bag is severed from the web of film under the action of lowering the punch and depressed by said punch until its margins come to lie under the clamping bar.
