Abstract
A device for pulling up the ends of transverse-conveyed flat tubular segments during the production of sacks or bags comprises lateral support elements, which run parallel to the conveying zone and between which a slit is formed that lies in the conveying plane and beyond which the ends to be pulled up project, and comprising mechanisms for pre-opening the ends by pulling apart the tubular sides that lie on top of each other. To pull up easily the ends of the tubular segments, the support elements in one section of the conveying zone form an obtuse angle in the shape of a peaked roof behind the mechanisms for pre-opening. In this section at least one roll is positioned in such a manner at the support elements that the leading tubular edge strikes the roll.
