A toroidal taping/winding machine builds and finishes ring-shaped coils. It loads wire or insulating tape into a shuttle (or magazine), rotates the toroidal core, and lays each turn with controlled pitch, speed, and tension. You’ll see these machines in transformer shops, EV power assemblies, audio power supplies, medical devices, and any place where low-leakage, low-noise toroidal parts are made.
In addition, when equipped with a taping head, the machine wraps paper/polyester/kapton tapes evenly around the core. This improves insulation and mechanical strength while ensuring a clean, uniform, and repeatable taping process.
This guide covers Guangri’s PLC-controlled models, including the JGC series. With a durable design and a smart PLC controller, operators can save recipes, switch between auto and pedal modes, and achieve consistent production across every shift.
Power & Safety Setup
Before starting any winding or taping operation, always put safety first. First, install the machine in a clean, well-ventilated area with a temperature of 13–35°C, low vibration, and no corrosive fumes. In addition, ensure proper grounding and use the correct circuit breaker for the power supply. These simple checks help prevent electrical hazards and protect both the operator and the equipment.
How to Power On Your Coil Winding Machine:
Release the Emergency Stop (E-stop).
Flip the power switch on the base.
The controller will boot into Waiting state. The “Ready/Waiting” indicator lights up when it’s ready. If it’s off, the machine is in Setting state, meaning parameters can still be adjusted.
Pro tip: Before loading a core, always double-check the grounding connection and confirm the E-stop reset is properly released. This helps avoid startup faults and ensures a smooth machine start-up process.
Front Panel Controls
Nine function keys on the tape machine handle power, start/stop, reset, manual jog, direction control, and auto/manual mode selection.
Two adjustment knobscontrol speed (winding/taping RPM) and pitch (spacing between turns or tape wraps).
The direction switch controls rotation direction, setting CW (clockwise) or CCW (counterclockwise).
The mode switch toggles between Manual mode (slow jog and setup adjustments) and Auto mode (continuous winding/taping).
Operation Flow of the Tape Winding Machine
Start/Stop key: arms the system and starts the cycle
Reset key: clears errors or gets ready for the next job
Manual mode: used for setup, coil positioning, or trial runs
Auto mode: enables repeatable, hands-free winding/taping with stored programs.
You can also run via foot pedal mode or switch to full Auto-start (machine ramps up and down automatically).
Rear Panel Switches
The base and rear control panels house all connections and deeper configuration settings:
Base sockets connect the controller, foot pedal, sensors, and—on taping machines—the auto-scissors, also including fuse access and main power input.
The mode selector switch lets you choose Pedal mode (pedal controls speed/stop) or Auto-start (automatic acceleration/deceleration by controller).
The grounding terminal must always be securely connected before operation.
On the controller rear panel, you’ll find several machine configuration switches:
Machine type switch: selects toroidal, belt/slider, gear head, or taping models.
Rotation switch: sets single or double-direction rotation when reversals are required.
Transducer switch: matches the correct sensor type(e.g., JG = 7PA, JGC = 7NA). an incorrect setting will prevent the counter from working.
Core start direction switch:sets the starting direction for fan-shaped windings in Auto mode.
Important: Set all rear-panel switches before the first power-up to ensure the controller recognizes the correct machine configuration.
Controller Programming Overview
Ae t thheart of Guangri’s toroidal taping and winding machines is the controller panel, where operators set up and manage every job. The panel uses four key display windows:
Specification window – stores job numbers and allows quick saving or recalling of coil specifications.
Program window – sets the working sequence, such as Load → Wind, with support for additional tap steps.
Times window – defines how many times each step repeats, reducing the need for repeated programming.
Turns window – sets precise turns for loading, winding, slowdown, and reversal in fan-shaped windings.
The machine operates through three control states:
Setting state – where parameters are entered and adjusted.
Ready state – once settings are confirmed, the machine is ready to run.
Review state – meanwhile, stored parameters can be checked before pressing Start.
Auto & Pedal Control Modes
Additionally, the Guangri machine offers flexible control, allowing smooth switching between pedal operation and Auto-Start mode.
Pedal mode: The operator controls speed and start/stop using the foot pedal—ideal for setup and manual machine control.
Auto-Start mode:Set via the rear switch on the base, the machine automatically ramps up to preset speed and smoothly slows down at the end without pedal input.
Notably, the proportional linking between the main drive and rotation drive is a key feature of the Guangri machine. It keeps wire pitch accurate at any winding speed, ensuring consistent spacing and tighter control across different coils.
Different winding heads need slightly different handling; the Guangri machine supports multiple head designs:
Slider head – First load the core, then adjust the friction spring and pressure pad to set proper wire tension; ensure the slider moves smoothly without blocking the wire.
Belt head – Secure the wire end, then fine-tune grip using the belt tension screw. Keep the free wire end stable under the core before winding.
Gear head – Set the brake to the correct tension before loading. Align the magazine and slider properly, and make sure the wire passes through the guide groove without slipping.
Taping head – Route the tape through the pressure clip and electric scissors before feeding it into the magazine. Once running, the machine applies tape automatically and the scissors cut it at the end.
Overall, each head type has its own setup details, but all share the same goal: maintaining stable tension control and ensuring precise winding or taping accuracy
Taping Calculations & Setup
Additionally, understanding a few basic taping calculations helps achieve accurate and repeatable results. The key formulas are:
Tape-turns = core circumference ÷ (tape width – overlap)
Load-turns = tape-turns × (one-turn length ÷ magazine circumference)
These calculations ensure proper tape overlap, helping maintain consistent insulation thickness and full coverage on every layer.
Example setup:
Measure the core outer diameter to determine the circumference
Select the tape width and desired overlap (e.g., 2 mm).
Calculate the required tape-turns using the formula.
Enter the load-turns value into the controller.
Run a dry test cycle to verify settings before production.
By following these steps, you can reduce trial-and-error while maintaining consistent taping quality and material efficiency.
Essential Switch Setup
Most importantly, before the first power-up, make sure all front and rear panel switches are set correctly. Missing this step may lead to counting errors, incorrect settings, or machine startup issues.
Mode: select Auto or Pedal operation based on your workflow.
Machine type: choose the correct winding, taping, or head configuration.
Rotation: set CW (clockwise) or CCW (counterclockwise) direction.
Sensor type: match 7PA or 7NA to the machine model, as an incorrect setting will prevent the counter from registering.
Operating Workflow
Every winding or taping job follows a clear and structured process to ensure accurate and consistent results:
Load setup: Open the shuttle or magazine and secure the core in place.
Roller adjustment: Set the polyurethane rollers for proper grip and smooth operation.
Threading: Route the wire or tape through the guides, pads, and tensioners correctly.
Start process: Press Start to begin. In Auto mode, the machine reaches the preset speed automatically; in Pedal mode, speed and movement are controlled manually.
Monitor: Adjust the speed and pitch knobs as needed to fine-tune spacing during production.
Record values: Save the speed and pitch values for quicker and more consistent future setups.
Maintenance Guide
To keep your toroidal winding and taping machine in top condition, only basic regular maintenance checks are needed. Start by greasing and cleaning all rotating parts and gears at scheduled intervals to ensure smooth motion and reduce wear.
Next, make sure the ventilation paths and cooling fans are clean and unobstructed, as dust buildup can cause overheating and shorten component lifespan. Also, verify proper grounding and confirm that breakers are correctly rated and functioning to ensure stable operation and operator safety.
Overall, just a few minutes of preventive maintenance today can save significant downtime and repair costs in the future.
Troubleshooting Overview
No LEDs lighting up → Check the power connection and main fuse of the machine system.
Motor won’t start → Verify the foot pedal function and ensure the speed knob is not set to zero.
Counter not registering → Adjust the transducer gap or confirm the correct type (7PA vs 7NA) is selected.
Rotation motor idle → Inspect and adjust the drive belt for proper tension and contact.
In most cases, machine issues come from basic power, sensor, or setup problems—so always check these first before contacting service support.
Best Practices
For smoother machine operation and fewer unexpected issues, follow these proven best practices:
Do a dry run: Mark the core and run without material to confirm and lock pitch settings before actual winding operation.
Save job cards: Store pitch, speed, and program values under unique recipe names for faster repeat setups.
Log key data: Record tape/wire usage, cycle time, and defect rates to optimize process performance and ramp timing.
Standardize setups: Prepare reference brake and pressure settings for common core sizes to improve changeover speed and consistency.
In summary, by combining preventive maintenance with smart data logging, you can reduce machine downtime while extending the service life of your Guangri winding machines.
