摘要： The arrangement provides warp threads for an oscillating weft thread magazine for warp knitting machine. The machine uses a creel, a first delivery device with constant delivery speed, and a second delivery device with a variable thread drive speed. The latter speed corresponds to the instantaneous take-off speed of the weft thread by the carriage. A storage arrangement is located between the two delivery devices for smoothing out the differences between the constant delivery speed and the variable take-off speed. This arrangement enables use of elastic weft threads on the weft thread magazine, so that they are provided in a state of constant tension stage; in particular, tension-free or very slightly tensioned.

摘要： 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.
