A cutting mechanism removes a first portion and a second portion of a first segment of the material segments in order to form a first cut and a second cut in the first segment and a sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall with a substantially flat, rectangular-shaped footprint.

A packaging machine forms, fills and seals a mixing pouch that includes a first compartment containing a liquid ingredient and a second compartment containing a light powdered ingredient with a breakable seal, preferably formed by an adhesive heat seal, between the two compartments to separate the two ingredients. The machine creates a breakable seal that can be ruptured to form a common interior cavity and allow the mixing of the two ingredients to create a mixed product. One end of the mixing pouch can be formed with a dispenser through which the mixed product is discharged for use. The mixing pouch is a flexible plastic member formed from two opposing plastic sheets, sealed through heat dies and supplied with powdered and liquid components before being completed. The operation of the machine is automated and powered through pneumatic cylinders. Alternatively, the compartments could be filled with different liquid components.

There is described a machine for packaging products in tubular wrappings of thermoplastic material obtained from continuous film unwound from a reel, equipped with a double transverse heat-sealing and intermediate cutting assembly that, with a horizontal translation movement, accompanies the pack that the assembly is closing the trailing end of to be unloaded while it is simultaneously closing the leading end of the tubular wrapper of the future pack that the heat-sealing and cutting assembly, also due to the presence thereon of pressers and counter-pressers, extracts from a tube-forming and longitudinal heat-sealing mandrel and that, by the same assembly, is separated from the pack upstream with a transverse cut.

At the end of its active movement, the transverse heat-sealing and cutting assembly opens and with a horizontal movement in the opposite direction to and at a higher speed than the preceding one returns to the cycle start position, upstream of a new pack already filled and ready to be heat sealed at the trailing end and accompanied to be unloaded, repeating the cycle described. The transverse heat-sealing and cutting assembly is aided by a conveyor that supports and advances the packs being formed and those finished and separated, and that is equipped with a gap with variable geometry, which opens during the active horizontal movement of the same assembly and closes during the reverse horizontal movement of the same assembly.
