Family of Coil Winders

RothGreaves standard and custom coil winders offer features like high-rpm motors, electronic spool tensioners, analog pitch compensators, EasyWind WindowsTM based software with full CNC coil winding control, multi-filar payout racks, and hot air torches. On-site training is available.

Automatic Coil Winders

RGA Automatic Coil Wire Winders run unattended to produce high- quality coils in large volumes. These coil winders are available in single arbor or double arbor configurations as well as custom lengths.

Manual Coil Winders

RGA Manual Coil Winders are available in standard sizes as well as custom sizes to suit your coil requirements. All models offer unique features not available from other manufacturers including EasyWind WindowsTM software.

Mini-Winders

RGA Mini-Winders are the same full-featured machines as the larger models and are perfect for R&D applications or light production.
All RothGreaves winders use the same EasyWind Software.

Arbor-Puller Winders

RGA Arbor-Puller winders automatically release the coils from the arbor after winding and coil cutting is built right into the machine.

Space-Saver Stacked Bed Winders

RGA Stacked Bed Winders combine two fully independent winders in one machine to save floor space. Each winder has all the features of our single arbor models while providing twice the throughput.

Side-Winder Hybrid Coiler

RGA Side-Winder is designed to transfer a coil directly to a mandrel without the coil springing back off the mandrel. Perfect for catheter manufacturing where the coil is formed at the mandrel diameter.
