Verfahren zum Zusammenbringen gefüllter Verpackungen

摘要

The present invention is a method to assemble filled packages together into a secondary package. This method comprises the steps of: (1) feeding a film (1) into a vertical-form-fill-seal (= VFFS) machine in a flat configuration; (2) carrying the film to the forming shoulder (10), the forming shoulder comprising a filling head (11) and extending in a vertical tube; (3) pulling the film around the forming shoulder (10) forming a tubular configuration of the film; (4) sealing completely or partially the vertical edges (2) of the film; (5) sealing the tubular formed film on the opposite end to the filling head (11) so as to form a bottom seal (3) and having an open bag representing a secondary package; (6) filling the secondary package with more than one filled primary package by dropping the primary packages through the filling head of the forming shoulder and through the open end of the secondary package; (7) sealing the open end of the secondary package substantially tightly around the filled primary packages contained in the secondary package so as to form a top seal (4) and closing the secondary package aound the filled primary packages; (8) cutting the closed secondary package above the top seal. To facilitate opening of the package any of the seals may be interrupted.
