An apparatus and a method for the processing of semi-finished sacks and a gluing station for semi-finished sacks include a feed element and a guide element. Semi-finished sacks having more complicated shapes, such as tubular pieces having open bottom squares with valve patches inserted therein, tend to be subjected to a partial gluing process or even suffer damage during the process of glue application in the nozzle clearance. Therefore, at least one feed element is provided, which is disposed upstream of a glue-application gap in the transport direction of the semi-finished sacks, and which together with the guide element defines a feed region of the semi-finished sacks to the application head. Components of the semi-finished sacks are guided through the feed region, which tapers in the transport direction of the semi-finished sacks.

Device and a method for processing semifinished bag products, and gluing station for semifinished bag products

A bottomer for the production of sacks, preferably cross-bottom valve sacks, includes at least one glue unit that applies glue to the components of the sacks. The glue unit includes a nozzle bar, which has at least one nozzle for extruding glue onto the sack components. The glue unit also includes a counter support, which positions the sack components with a force against the nozzle bar.

Backing run for nozzle paste application

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.

Device for placing a paper bag bottom

The present invention relates to a base insert device for crossed base valve bags for the formation of crossed bases in paper bags, by means of folding devices which introduce folds at the ends of the tubular sections from which the bags are produced, with one or more gluing stations, which apply glue to the regions of the folds for gluing and/or the sheets () provided for gluing to the base, in the gluing stations and at least one pressing station in which the folded bases and the sheets () are brought into contact and glued. The novelty of the present patent application is that at least one gluing station for the sheets and/or bases is provided, comprising glue outlet openings () which may be selectively supplied with glue, whereby the selection of the glue outlet openings () defines the format of the glue application (). Said glue outlet openings () are provided with at least two application heads () of which at least one application head () may be displaced in a direction (y) orthogonal to the feed direction of the sheets () and/or the folded bases such that as a result of the displacement, a relative movement of the two application heads () occurs.
