Patent ID: 8216119

Claim:
A base insert device for making cross bottoms on cross bottom valve paper bags, comprising: folding devices that make folds at ends of tube sections from which the bags are produced to make a folded bottom; one or more gluing stations configured to apply a starch glue to at least one of areas of the folds to be glued and labels provided with the bottom for gluing, the gluing stations including glue outlets which can be fed selectively such that a format of the applied glue is defined by selection of the glue outlets, and at least one application head to which the glue outlets are assigned; and at least one press compaction deck in which the folded bottoms and the labels are brought into contact with each other and glued, the application head having mounted thereon a valve which can selectively open and shut a connection between the glue outlets and a glue feed, and the glue feed including (i) at least one chamber through which at least one part of the valves is fed with the glue and which has a diameter of at least 5 mm in at least one place, and (ii) at least one glue supplying line which extends to the application head, the glue supplying line engaging into the chamber and the application head mounted to displace along the glue supplying line in a direction y extending perpendicular to a transport direction x of the bag and in a plane parallel to a plane in which the bag lies during transport so as to enable the glue outlets to apply the glue to all regions in the y direction of the areas to be glued.
