Device for placing a paper bag bottom

Abstract

The inventive device for placing a paper bag bottom (1) produces score lines on the ends of tubular segments which are used for producing bags (1), applies glue layers to the folded bottoms on the extremities of the tubular segments and/or to sheets (2) for gluing them with the bottoms with the aid of gluers (10, 20, 30, 40), connects and glues the folded bottoms (1) and the sheets (2). Contrarily to presently used devices, said device is provided with at least one gluer (10, 20, 30, 40) which comprises at least one glue reservoir (21) or at least one glue duct (33, 52, 53), the glue contained in the reservoir or in the duct being exposed to a pressure higher than ambient pressure. The glue reservoir (21) or the glue duct (33, 52, 53, 55, 72, 73) is provided with at least one output orifice (71) for applying the glue to the sheets (2) and/or to the folded bottoms (1). The inventive method for operating said device is also disclosed.
