The invention relates to a packaging machine employing a double strip of sheet material issuing from one or two rolls. The machine consists in an arrangement comprising an oscillating filler assembly being made up of an associated filler tube being arranged within a double strip in which the triangular packages are formed at its end, these latter being filled with the product to be packaged and being thereupon closed, said machine according to another arrangement comprising a double strip being formed out of a sheet issuing from one roll, said sheet being folded and cut along the fold line, or out of two addorsed sheets, a succession of weld lines being made along said double strip, said weld lines having mutually opposite inclinations and forming an angle with the longitudinal axis of the double strip and thus forming V-shaped weld lines defining the succession of triangular packages that are filled with the product and ulteriorly closed. Respective methods are also described. |
