CWF represents a revolutionary new generation Wire Constant Tension Feeding device, unique in terms of functionality and performance, capable of adjusting with utmost accuracy the tension of the finest wire range in coil winding processes.

An innovative Solution based on the BTSR Dual-Drive Feeding System, Tension Profiler Function and Double Loop Control System bringing new and unique measurable benefits in terms of TOP Quality Control and Production Efficiency in coil winding processes.


CWF 2000 ensures the highest coil winding quality and repeatability, thanks to BTSR 'Double Closed Loop' Technology guaranteeing the most accurate and precise wire tension control.

The advanced BTRS MOTOR TORQUE Control System detects and adjust wire imput feeding tension change, thus avoiding undesired wire stretches.

Tension Profiler Function (BTSR Patent) - possibility to program up to 3 different wire feeding tension values without any interface/connection to the coil winding machine or up to 4 different wire feeding tension values during winding cycle, utilizing two digital outputs.

Wire 'Storage and Release' capability (BTSR Patent) - able to manage sudden wire absorption or release during the working process and simultaneously keeping the wire feeding tension at the set value.

Fully programmable - easy parameter setting (Tension Profiler, % tolerances, ...) for diversified working conditions.

A wide application range - A single device able to cover a wide wire tension and diameter range.
