Abstract
A device for producing a longitudinal seal between two juxtaposed plies of film that are conveyed along a longitudinal path of travel, the juxtaposed film plies including a series of containers therebetween, wherein the device includes a sealing mechanism that forms a sealing zone in the travel path in which the longitudinal seal is produced, and a pressure mechanism that forms a pressure zone in the travel path in which the juxtaposed film plies are compressed, the pressure zone being positioned between the containers and the sealing zone.
