Abstract: Machine that consists in a horizontal sequence: a uncoiling station for a flexible sheet, a station for the formation of the packet in a folded “V”, a sealing station of the packet, an individual cutting station of the packet, a station for the individual transport of the packets to a filling station, and a station for the closing of the packets. The sealing and cutting stations comprise longitudinal guides 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.

Abstract: A longitudinal continuous welding device for packaging machines includes structural features aimed at enabling it to act continuously on opposite sides of layers of material to be welded, joining and welding them continuously, as they pass through the inside of the welding device, while the device remains static, without the possibility of movement in the direction in which the layers of material to be welded advance.
