UPLOAD System: Hydraulic unwind-arm uploads parent roll
UNWIND System: AC servo motor drive active shaftless unwind Unwind-arms’ distance is adjustable by motor E+L Photoelectric guiding system (EPC) Compensation roll(dancer roll) up-down direction slides Unwind tension is controlled by unwind motor, compensation roll, position detection and film, and keeps constant
TRACTION System AC servo motor drive active traction rolls All rolls are wrapped by sawdust belt from Germany All rolls are positioned in Ω shape, decrease the tension influence between unwind and rewind stations 3 distributing rolls are covered by EPDM in diamond-shaped groove Kickert spread roller from Germany, adjustable bow influences film running over it
SLITTING System: Cylinder controlled blades, knife groove roll, rotary shear or razor TRIMMING COLLECTION System: Pipe blow + rewind Holes in Pipes are adjustable according to film’s width 2 trimming rewinding units use AC servomotor
REWIND System Centre rewind stations,3”6” chuck, 6 stations duplex averagely Rewind arms are made of alnico, chucks are made by special material Independent contact roll for each station, and slips by cylinder Cylinder’s pressure is programmeable controlled by proportional valve Each station driven by one set AC servomotor, for wide film rewinding, pair of motor driving is realizable to increase rewind tension.
OFFLOAD System Rewind stations are revolved to the offload position, shift finished roll to trolley
CONTROL System: Siemens simotion (the most advanced control system)
