摘要

The invention relates to a packaging machine made up of two vertical packaging groups (1 and 2) set on the opposite sides (3 and 4) of a central structure (5) equipped with a horizontal bilateral station (6) that carries out the transversal sealing of both resulting packets (15 and 16). Compared with the utilization of two different packaging machines, this structure allows smaller overall dimensions, cheapness and an easier way of realization and use, even making two packets with different features simultaneously.
