Abstract
In a method and an apparatus for producing tubular hollow items, in particular for containers, form card material or the like, to improve the efficiency and thus to reduce the costs on the production of known packages, the following steps are proposed: transporting a blank bound by longitudinal edges, or a web of card material or the like, from which the blank is separated into a bending station, the blank or the web being bent by guide elements acting as a bending apparatus and then being held stationary in the bending station and being bent by means of movable bending apparati into the finished shape of the hollow item and an overlap region being formed, in which the two longitudinal edges of the blank, which are parallel to the longitudinal axis of the hollow item, are placed one on top of the other and are connected to one another and the hollow item being conveyed out of the bending station.
