HZW-4-300 weft insertion machine

Product Introduction

Equipment Overview: This machine is designed for winding weft yarns onto weft tubes in circular paper‑making bottom‑mesh weaving machines. It enables fully automated operation across all stages, including material retrieval, conveying, feeding, clamping, winding, full‑tube pressing, cutting, and discharge. The weft‑yarn supply system incorporates a yarn‑storage unit, enhancing tension stability and ensuring consistent tension during the winding process. By reducing labor and effort while boosting efficiency, this model is ideally suited to improving the efficiency of weft‑yarn and weft‑tube supply in the paper‑making felt‑bottom‑mesh industry.
