The function of the SBMC fully automated flow pack machine is to bag paper rolls individually utilizing a tube of PE-film, formed from a flat-film roll. All sides of the bag are sealed. Rolls advance through the bagger where a film tube is formed when the roll is transferred through the inner tube of the forming collar. The film is drawn over an engineered curved surface and through a non-contact hot air seam welder producing a smooth predictable sleeve of film around the roll. As the roll passes through the machine, heated upper and lower seal bars close to seal the end of the bagged roll. An exit conveyor moves the roll out of the SBMC to an accumulation table or to the next packaging line sequence.
