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

A gluing station for semi-finished sacks, said gluing station comprising:

• a glue-application head;
• a transport medium that feeds the semi-finished sacks to the gluing station in a transport direction (z) such that the semi-finished sacks can be guided past the glue-application head;
• a feed element, which is disposed upstream of and adjacent to a glue-application gap in the transport direction (z) of the semi-finished sacks, and which together with a guide element defines a feed region of the semi-finished sacks adjacent to the glue-application gap,
• through which feed region at least components of the semi-finished sacks are guided,
• and which feed region tapers in the transport direction (z) of the semi-finished sacks,
• with an angle (β) between the guide element and the feed element in the tapering feed re ion being in a range of 1° to 45°.

A method of processing semi-finished sacks with a bottoming apparatus,

• the bottoming apparatus having a gluing station with a glue-application head, and
• the semi-finished sacks being fed to the gluing station and guided past the glue-application head by a transport medium,
• said method comprising:
• feeding at least components of the semi-finished sacks to the glue-application head through a feed region thereof,
• and exposing at least the components of the semi-finished sacks to an increasing pressure as the components pass through the feed region, with the increasing pressure acting in a direction (y) extending transversely to a transport direction (z) of the components of the semi-finished sacks.
