Purpose: For automatic filling and packaging into 3-seam "Stick" bags from a roll of film.
Products: Free-flowing small granular food products and materials for technical use: sugar, salt, spices, seasonings, granulated and freeze-dried coffee, granulated tea, sugar sprinkles, dietary supplements, fertilizers, agrochemicals, and more.
Packaging materials: BOPP films, laminates, laminated paper, multilayer films. Thickness — from 20 to 70 microns.

Operating principle: The film is unwound from the roll, passes through the tension roller, photo mark detection zone, and slitting knife, where it is cut lengthwise into three equal strips. On collar formers, the strips of packaging material are formed into three tubes. Longitudinal/center seams are sealed. Then, the horizontal sealing jaws unit seals the film with two transverse seams and makes a cut between them. At this stage, the previous bags are sealed and the bottoms of the next bags are formed. Once the new bags are formed, the machine sends a command to the dispenser to release a dose. The dispenser dispenses a dose of product through the filling tubes into the prepared bags. Simultaneously, the bags are pulled to the required length. The bag length is controlled by a photo mark printed on the film, or, if the material has no photo mark, by the length set on the machine. After the product is filled and the bags are pulled, the machine sends a command, and the horizontal jaws unit begins the next automatic cycle — sealing the previous bags and forming the bottoms of the next ones.

Operator actions: The operator monitors the product level in the loading hopper, loads the film, adjusts the dosage and other variable parameters. The finished product is packed into group packaging (if the group packaging option is not installed).
