Apparatus for transferring weft threads in a wrap knitting machine

摘要

There is provided a novel system for increasing the accuracy and delivery speed of weft thread insertion in warp knitting machines. The system includes a novel transport arrangement for providing magazine weft threads proximate to the needle bar and a knockover sinker bar whose knockover sinkers are operable to pass between the needle spaces to grip the weft thread. The system is most suitably employed in a warp knitting machine producing a fabric containing an intermediate layer such as a non-woven fabric overlayed with weft threads. This machine comprises a needle bar, at least one guide bar and an arrangement for providing the intermediate layer between the needles and the guide bar.
