1. The host adopts a variable frequency motor, which is controlled by a vector frequency converter for closed-loop control, with precise speed and uniform adhesive application at low and high speeds.

2. The tension of the unwinding base is controlled by a 2.5Kg magnetic powder brake with an accuracy of ± 0.5Kg full width (KORTIS).

3. Constant tension control for unwinding and inertia compensation for acceleration and deceleration tension.

4. The alignment of the base is achieved through the use of a Timaco servo driven ultrasonic tracking correction machine, with an edge to line accuracy of ± 0.1mm, a tracking line speed of 25mm/s, and a pushing circumference of ± 70mm.

5. The unwinding shaft adopts an expansion type inflatable shaft with a diameter of 3 inches and a diameter of 74mm. The edge correction and live pressure use a linear shaft and linear bearings for operation.

6. The diameter and width of the traction steel rod pressure rod are Φ 90mm × 320mm, and the surface is coated with a hard baked and finely ground mirror finish.

7. The diameter and width of the traction rubber stick are Φ 90mm × 320mm, and the rubber material is polyurethane.

8. The steel rod clutch adopts simultaneous pneumatic operation at both ends, with a cylinder diameter of Φ 50mm × 20mm stroke and adjustable air pressure.

9. The traction rubber stick is independently driven by a variable frequency motor transmitted from a synchronous belt.

10. The winding shaft adopts Flat noodles type air expansion shaft with a specification of 3 inches Φ 74mm.

11. The winding adopts an independent motor and magnetic powder combination to control the winding tension. The magnetic powder generates less heat and can achieve stable small tension control.

12. Winding taper tension (radius tension curve, speed tension curve).

13. When the winding length or diameter reaches the limit, the machine will automatically stop, and when unwinding with a smaller diameter, the machine will automatically stop.

14. The adhesive coating adopts electromagnetic needle cutting, and the flow metering pump is automatically controlled. The flow rate can be automatically adjusted, and the adhesive will be automatically dispensed when the machine is turned on and closed when the machine is stopped. 15. The intermediate guide rod of the whole machine is made of aluminum alloy material, and the surface of the guide rod is hard anodized (called brown guide rod). The guide rod is dynamic and static balanced with ± 0.4g, and the adhesive specification is applied; Φ30mm—Φ300mm， Maximum speed of adhesive application; 300m/min， Palm closing accuracy; ± 0.3mm.
