Description of operation:

 The packaging machine SB51-2LS is a vertically operating, fully automatic forming-, filling- and sealing machine for the production of very small tubular bags, the so called “Stickpacks”.
The machine processes flexible, composite films (foils) from the flat foil reel.
In a sequence of single operations, the film is drawn off from the reel, formed to a tube during transportation and sealed lengthwise, filled then, sealed transversally and cut off.
A photocell control assures the exact positioning of the print.
The packaging machine SB51-2LS is conceived as a 1-lane basic machine for the production of bags, constructed as a double machine. This means that there are two machines in the housing which are operating independently from each other.
In combination with different product supply systems and dosing units, a wide range of products can be packed.
