Carbon Fiber

EF

  • Processing/post-processing

Ideal for prepreg manufacturing and fly weld processes. A dedicated yarn unraveling machine that stably unravels yarn with constant tension.

Unwinder for a Wide Range of Special Processing Steps

This unwinder is used in prepreg manufacturing, filament winding, and special processing steps to unwind filament threads from krill stands with consistent tension, or to unwind (rewind) threads from unwanted winding packages.

Active Drive System to Protect Delicate Fibers

Even with delicate threads such as carbon fibers that are easily damaged, the active drive system using a motor ensures smooth unwinding without applying excessive tension to the thread.

High-Precision Tension Control with Dancer Rollers

The dancer roller’s tracking control maintains a constant low tension while unwinding the thread. Even when the diameter of the yarn package decreases, tension fluctuations are minimized, allowing for stable supply to the next process.

Smooth Speed ​​Synchronization with Other Equipment

Designed to track the processing speeds of preceding and succeeding equipment, it also supports speed synchronization with feed rollers, winders, etc. It supports smooth, integrated production in coordination with the entire line.
