2. Unwind unit

Pre-transmission system: Fix new roll on the B shaft with adhesive tape, when the roll diameter on the A shaft reach to the set value, the ring sounds and press the prepare roll change button to let the turret rotate to a suitable angle, then the B shaft start speeding, when the line speed reach to the current printing speed, press roll change button, the roller will push the material to the new roll, then new roll will adhesive to the old roll then cutter fall down to cut off the old roll, now roll change finish.
Horizontal adjustment of printing material manually
Air shaft
Auto splicing and cutting, pre-transmitting system for roll changes.
Max diameter of unwind: 600mm
Floating roller to adjust the tension.
Two unwinding shafts are transmitted independently by two servo motor, when change the roll, no need to slow down the speed or stop the machine.
Dual station turret with automatic rotation.

3. In-feed unit

Floating roller to adjust the tension, absorb tension fluctuation and make printing job accurate, tension floating roller potentiometer can do position inspection, and realize close loop tension controlling.
Pneumatic rubber roller control
In-feed roller is driven by servo motor
Double roller rolling type, combined with steel roller and rubber roller.
