GW PRECISION TWIN KNIFE SHEETER D150/D170/D190
According to GW product’s technics, The machine are mainly used for paper sheeting in Paper Mill, Printing House and etc, mainly process including: Unwinding—Cutting—Conveying—Collecting,.
1.19" and 10.4" dual touch screen at cutting unit and delivery unit controls are used to set and display sheet size, count, cut speed, delivery overlap, and more. The touch screen controls work in conjunction with a Siemens PLC.
2.The high-speed belt is driven by British CT high-power servo to ensure smooth paper output.The pneumatic waste ejecting structure remove waste paper and improves the convenience of operation. The gas spring belt tensioning device ensures that each belt can run smoothly.
3.The TWIN KNIFE cutting unit has a synchronic rotary cutting knife like scissors on the material to make a smooth and accurate cutting for paper from 150gsm and up to 1000gsm.The knife roller and paper pulling roller are separately driven by 2 CT high power servo from UK, adopt a gap-free gear structure design, and with GW's 5 axis high accuracy CNC to machine the main stand in one piece. to effectively eliminate the shaking gap of the two knives, ensuring the life of the blade and cutting accuracy. which guarantees the stability of the tool body during high-speed operation.
4.Three sets of heavy duty pneumatic slitters ensure stable and clean slitting. Electrical driven automatic cutting width adjustment.(*Option).
5.Dual shaftless back stands with web tension controls and pneumatic brake units are standard.
6.The spray gear lubrication system ensures the gears are fully lubricated during the entireoperation. Effectively extend the service life of the machine.

1. Dual position shaftless pivoting arm unwind stand
Dual position shaftless pivoting arm unwind stand with in-floor track and trolley system.
2. Air cooling pneumatic disc brake
Air cooled pneumatic controlled disc brakes on each arm.
3. Auto tension based on reel diameter
Auto tension controller gives you fine control on the tension especially for small reel.
4. EPC web guiding
EPC sensor coupled with an independent "swing frame" allows for minimum edge trim of the web, and strict control of the web edge throughout the reel from start to finish.
5. Servo controlled decurler system
Servo controlled decurler system can automatically detect the diameter of paper and adjust the recurve power, the coefficient can also be set by different material gsm, and the recurve power will follow the set material and diameter.
6. Twin Knife driven by servo motor
a.The twin helical knife ensures the very sharp and clean cutting edge with high accuracy
b.The blade is made of special alloy st eel SKH.9 with long life and easy maintenance.Twin knife roller and paper pulling roller are driven by separate servo motor.
7. Three sets of Pneumatic Slitters
Heavy duty pneumatic slitters ensure stable and clean slitting.
9. Out feed and overlapping section
a.Fully synchronized speed between high speed outfeeding and overlap tape section to maintain a proper shingle.
b.Overlapping unit with adjustable overlapping value and jam-stop sensor. Single sheet outlet can be set.
12. Siemens touch screen
Length of cut, quantity, machine speed, cut speed can be displayed and set via touch screen.
