Abstract:
A method of producing a package having first and second side walls joined to side fold sections and a bottom section joined to said first and second side walls and to said side fold sections, comprising transporting in a first direction (2) a continuum of first packaging material (1) which is to form said first side wall of said package, transporting in said first direction (2) a continuum of second packaging material (3) which is to form said second side wall of said package, transporting in a second direction (7) a plurality of individual lengths of third packaging material (14) having overlapping folded parts (12) which are to form the side fold sections of said package, transporting in said first direction (1) a continuum of fourth packaging material (21â€²) having overlapping folded parts which are to form the bottom of said package, disposing said fourth packaging material (21â€²) in at least a partial superimposed relationship with said first packaging material (1), disposing said first and fourth packaging materials (1, 21â€²) in at least a partial superimposed relationship with individual lengths of said third packaging material (14), transporting said at least partial superimposed first, third and fourth packaging materials (1, 14, 21â€²) in said first direction (1) into at least a partially superimposed relationship with said second packaging material (3), joining at least parts of said at least partially superimposed first, second, third and fourth packaging material (1, 3, 14, 21â€²), and severing said first, second, third and fourth packaging material (1,3, 14, 21â€²) along a severing line extending generally transversely of said first direction (1) to thereby provide a plurality of packages each formed by severed lengths of first and second packaging materials (1,3) which form the first and second side walls of the package, by severed lengths of third packaging material (14) which form said side fold sections of the package, and by severed lengths of fourth packaging material (21â€²) which form the bottom of said package.
