Driving Mode
- Inverter controls speed continuously and accurately.
- Transmission combines of main shaft, couple of jointers, integrity of gearboxes and phasers, time belts and etc.
- Main positions adopted universal couple, increase the parallel between up and down roller to minimise the driving error for reliable performance.
- Main driven shaft adopted 45 quality adjusted and connected among each other by means of universal couple.
- Integrative gearbox phase application, to minimise the gear gap, ensure driven precision and speed synchronised to speed variation.
- Adopted widen time belt for high-tension suffered parts.

PLC Automatic Functions
- Programmable interface, easy to operation.
- Auto unwinding and tension control for N.W, PE Film,
- Auto check for raw materials, machine can be shut down automatically at the shortest time while raw materials lacking or breaking off.
- Raw materials auto splice: photo sensors check the trail and feed back to the PLC issue instruction to spliced cylinder completing splice motion, and cutting the spliced material to minimise the defectives.
- Auto check and rejecting for raw materials spliced part by photo sensor.
- Auto rejecting spliced by and other defective products to increase acceptance rate. The rejected number can be set up freely.
- Auto alarming and shut down at abnormal gas and voltage.
- Edge guiding system for top sheet, back sheet, and etc. The 1mm accuracy ensures the right precision.
- Glue Auto compensating electrical cam to freely adjust the glued length and initial position, the glue can be auto compensated with the variable speed to guarantee the glue position.
