Semi-Automatic Transformer Coil Tape Winding Machine for Bobbin and Magnetic Core Coils WM-470
The WM-470 winds adhesive tape around a wound coil clamped inside a rotating ring — the tape arm travels a full circle around the coil body, so each turn closes on itself without threading the reel through by hand. It runs at 46 pcs/min with a ±0.2 mm tolerance range, takes tape reels with a 34 mm or 77 mm core, and the tape axis spacing adjusts from 25 to 85 mm. Benchtop format: 250 × 550 × 300 mm, 30 kg, on a 220 V AC 50 Hz 60 W supply.

Key features
- Ring-type taping head — the coil is clamped on a spindle inside the open ring and the tape arm orbits it, laying a closed wrap around the winding instead of a short band across it
- Two-axis tape wrapping with the tape axis distance adjustable from 25 to 85 mm, set against the graduated scales on the ring face
- Tape position is fine-adjustable and the reel tensioner is adjustable, so wrap placement and tightness are dialled in rather than fixed by the tooling alone
- Fixtures are interchangeable — a different coil or bobbin runs on its own clamp set, changed at the spindle without touching the taping head
- Digital output counter with turn setting on the front panel; auto and manual (setup) operation
What it processes
- Insulation tape on transformer bobbin windings before assembly, potting or varnishing
- Magnetic core coils, resistance coils and relay coils that need a full-coverage tape layer over the winding
- Small inductor and choke coils built on pin-terminal bobbins, taped one at a time from a fixture
Suited for: full-coverage tape winding on small wound coils — transformer bobbins, magnetic core, resistance and relay coils — loaded one at a time into a fixture, 46 pcs/min at ±0.2 mm. Not suited for: short tape bands placed at intervals around large wound coils and ring cores — that is the WM-468 toroidal coil tape wrapping machine, which lays one band per 1.5-second cycle with 10–15 mm tape. For continuous spiral taping along a wire harness bundle, use the WM-467 automatic wire harness taping machine for Φ3–30 mm bundles; for spot taping at programmed points, the WM-464 two-station spot taping machine.
Coil taping is fixture work: the taping head is standard, the clamp that holds your coil is not. Include the coil dimensions, the pin or lead arrangement and your tape spec in the inquiry so the fixture and the tape axis setting are confirmed before the machine is quoted.

WM-470 — common questions
What coil sizes does the WM-470 handle?
The published data covers the tape axis distance, adjustable from 25 to 85 mm, rather than a coil size table — actual fit depends on the clamping fixture, which is matched to the coil or bobbin you run. Send us a coil sample or drawing with your inquiry and we confirm the fixture and the working range before you order.
What tape does it take?
The machine accepts reels with a 34 mm or 77 mm inner core. The supplier data sheet does not publish a tape width range, so tell us the tape you use — width, thickness and material — and we confirm it against the tape guide and tensioner before quoting.
How fast is it, and how repeatable?
Rated working speed is 46 pcs/min with a tolerance range of ±0.2 mm. Cycle time in your plant also depends on how quickly the operator loads and unloads the fixture, since loading is manual and only the taping cycle is automatic.
What utilities does it need?
A 220 V AC 50 Hz single-phase supply drawing 60 W is the only utility listed on the data sheet — no compressed air line is specified for this model. The machine weighs 30 kg in a 250 × 550 × 300 mm benchtop footprint, so it sits on a workbench without a stand.
