Abstract
The disclosure relates to a device and a method for producing packages, in particular sachets, filled with liquid or pasty filling material, in particular with liquid or pasty food, with a co-extrusion device for co-extruding a strand made of curable casing material filled with the filling material, wherein the co-extrusion device comprises a filling tube for ejecting the filling material as well an extrusion nozzle being associated with the filling tube and having an extrusion gap for ejecting the casing material, the filling tube protrudes over the extrusion gap over a distance X such that the casing material is extruded through the extrusion gap onto the filling tube and can solidify along the filling tube. The protruding filling tube there expands at least in sections in the direction of the outlet opening and stretches the extruded casing to create a plump package.
