Packaging machines of the AMT type range process – depending on the selected batcher – powdered, liquid or lump products into triangular-shaped TETRA sachets or stick-shaped STICK sachets. The AMT type range is a multi-tube vertical packaging machine in which the sachets are formed from a never-ending roll of thermally sealable foil. The attractive shape of the sachets is determined by the actions of a crosswise jaw that alternately closes the sachets at 90° angle, thus creating the triangular shape. All machines of this type range are equipped with an electro-pneumatic drive gear.
