ABSTRACT:
A device for placing a paper bag bottom produces score lines on the ends of tubular segments which are used for producing bags, applies glue layers to the folded bottoms on the extremities of the tubular segments and/or to sheets for gluing them with the bottoms with the aid of gluers and connects and glues the folded bottoms and the sheets. The device has at least one gluer which includes at least one glue reservoir or at least one glue duct, the glue contained in the reservoir or in the duct being exposed to a pressure higher than ambient pressure. The glue reservoir or the glue duct is provided with at least one output orifice for applying the glue to the sheets and/or to the folded bottoms.
