Nozzle e.g. flat nozzle, manufacturing method for carton package for beverages, involves dividing pre-product into sleeve-like preforms, and converting preforms into press device by mechanical force impact in nozzle

The method involves manufacturing a tubular pre-product in an extrusion process, and dividing the tubular pre-product into sleeve-like preforms (4). The preforms are converted into a press device by mechanical force impact in a nozzle. A two-layered pre-product is extruded with a boundary layer. The preforms are converted into the nozzle by using a support pin. An external contour of the nozzle is produced by an external form (2). The preforms are converted into the nozzle by using pins (5) expanding the preforms. Tubes are extruded as the pre-product. An independent claim is also included for a device for manufacturing a nozzle for a container.
