Machine that consists in a horizontal sequence: a uncoiling station (1) for a flexible sheet, a station for the formation of the packet (2) in a folded "V", a sealing station (3) of the packet, an individual cutting station (4) of the packet, a station for the individual transport (6) of the packets to a filling station (5), and a station for the closing of the packets. The sealing and cutting stations (3 and 4) comprise longitudinal guides (33, 43) for the assembly of sealing and cutting means corresponding to a linear displacement means which provides alternate linear movements forwards and backwards in the trajectory of the flexible sheet. With each forward movement, said means moves at the same speed as the flexible sheet, and is placed in an operative position by a driving means. |
