Abstract

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.
