Multi-function cylindrical laminating machine Making use of the good adhesive property of polypropylene & polyethylene at melting status, the machine adheres and laminates paper or color-printed opp & cpp film to woven bag under pressure, and through cut-off and sewing to make paper & plastic laminated or color-printed packaging woven bags. The laminating with melted polypropylene & polyethylene film on the woven bags of instant noodle, melon seeds and foods. The extruder with helical gear reducer of 20crmnti alloy steel adopts automatic temperature-control system to adjust melting temperature, the the screw and cylinder are made of 38crmoaia alloy steel and done treatment of nitrogenation. The double-die can realize single or double-face coating, width of coating&laminating can be regulated, and stepless speed regulation is to control coating thickness and laminating speed, 6 wind-up station for material feeding. The gas-liquid edge correcting for rewinder assures the accuracy of coating. Pnenumatic roller can assure even pressure . Automatic edge cutting , edge-blowing , perforating , edge-folding , cutting-off and winding devices are applied.
