d. Inner support structure of roller: guiding column.
e. The back/forward movement of roller is driven by chain, and its upward/downward movement is driven by gear.
f. The screw bar can be adjusted manually to change the distance between upper / lower rollers to deal with sheets of difference thicknesses.

5. Post-cutting system
a. Cutting blade material: Cr12 with quenching treatment.
b. There is no material wasted after cutting.
c. Welded frame for enhanced rigidity.
d. The power of cutting is provided by electric motor.

6. Runout table
Two runout tables are designed for supporting the finished panels. It is 2-meter long.

7. Hydraulic system
a. Separated hydraulic stations are designed for main machine and decoiler.
b. Main valve: well-known Chinese brand.

8. Electric control system
a. PLC control technology to realize automatic production.
b. User-friendly man-machine interface facilitates the setting of plate length, quantity, etc.
c. Operation mode: input screen and buttons.
d. Encoder calculates and measures the length.
