Abstract
The invention is directed to a warp knitting machine having a weft thread insertion arrangement comprising two parallel transfer devices which carry the weft threads in holders having a predetermined separation from each other and which are driveable in the direction of the needle bed. Also included is a reciprocally moveable weft sled arrangement carrying thread guides to lay mutually crossing layers of diagonal weft threads that subtend mutually opposed angles to the stitch rows. The guides place the threads into the weft thread holders first in one of said transfer devices and then in the other transfer device in exact and predetermined separations. The invention is further directed to a novel fabric having inlaid weft and warp inlay threads.
