PVC Electrical Tape Coating Machine

1350mm PVC electrical tape coating Machine

Feature

1.It is suitable for specialized manufacture of PVC electrical adhesive tape 2.Man-machine interface using touch-screen control, PLC program(Mitsubishi), frequency conversion control technology. Auto-unwinding, rewinding, keep tension when stopping machine, auto control of air inlet and outlet process, to confirm the dynamic tension (of traction, oven, coating glue and rewinding) synchronize with each part of production speed, keep constant tension of material. This machine including dynamically display technical process, filed data and alarm,high precision, energy-efficient, easy operation, safe and so on.
