Abstract
Abstract Means are provided for keeping a plurality of weft threads of knitting and weaving machines separated so that they cannot cling or cohere and form defective warp knit goods. An endless moving belt is arranged obliquely across the width of the readied weft and provided with pins whose movement is coordinated with the speed of the weft feed.
