WF-510 Weft Yarn Feeder

This weft feeder is for weft insertion of flat-type material such as tape yarn, prepreg tape, carbon fiber etc., without twisting the fiber. The unit is an alternative for conventional accumulators, or applications simply taking the fiber off the end of the package, which will twist the yarn during the process.
Description

This weft feeder is for weft insertion of flat-type material such as tape yarn, prepreg tape, carbon fiber etc., without twisting the fiber. The unit is an alternative for conventional accumulators, or applications simply taking the fiber off the end of the package, which will twist the yarn during the process.

Yarn is stored in a u-shape by suction air to avoid twisting. This also helps prevent fuzz on the finished fabric product.

Stored yarn length is maintained by positioning sensor. Package drive motor is coordinated with loom speed via controller. Utilizes high accuracy laser beam fiber sensor with digital fiber amplifier for reliable performance.

The unit does not require a timing signal from the weaving machine, so the storage feeder is ready to go once it is set-up beside the loom.
