I Description
This machine is special designed for taping fiberglass and film to copper/aluminum wires, section area 5~40mm2.
It is of twin-head structure, each head has their own control system.
By adding high-frequency sintering device, this line can produce special film-taped magnet wires.
II Production flow
Pay-off → straightening→ polishing & cleaning → taping film → varnishing (impregnating tank 1# )→ concentric taping (fiberglass taping head 1#) → varnishing (impregnating tank 2#) → concentric taping (fiberglass taping head 2#) → varnishing (impregnating tank 3#) → towing (active towing device) → baking → varnishing (impregnating tank 4#) → baking → auxiliary towing device → applying self-adhering glue → baking → auxiliary towing → length counting → take-up
