Working principle The rolls are coming by 3 channels conveyor; they are launched in the number of lanes according to packaging configuration needed, which is set by HMI, in the single layer into in-feed section, where they are transported by group of carbon bars mounted on trimming belts. Carbon bars convey the group of rolls on the elevator, which leads them into the area of folding. The foil positioning section brings the packaging film directly above the rolls by transport belts. The folding process is performed by universal side folders, as well bottom folder and counter folder. Side folding is done by innovative air supported mechanical folders. The overhead pack transport section continuously moves the pack through section of side folding and rotating bottom sealer and deliver pack to side sealing section. All motions and functions are fully controlled by independent servo motors and inverter motors.
