In the double needle bed warp knitting, as the design later developed into a universal machine, mainly knitted shawls and scarves. Like rib weft knitting, the needle bars alternately arrange the machines in a back-to-back manner, but soon they are placed completely behind each other to facilitate the guide bar swinging. Six to eight guide bars and various accessories are used, such as a lowering plate, a wrinkling movement (you can disconnect a needle bar to select a predetermined stroke), and a switch device for moving the guide bar push rod.

Move from one track of the pattern chain to another, and perform simple weft inlay or insertion. The front needle bar can be replaced with a pointed rod used to make plush and pile structures, or it can be completely removed, so that the rear needle bar can weave a single-sided fabric driven by a new set of cams, thereby increasing the speed of knitting Double.

Improvements in weft knitting and single bed warp knitting machines have isolated the double needle bed into a slow, coarse gauge and very bulky machine. However, the component arrangement and weaving function of the warp knitting machine is not as complicated as that of the simplex machine, so it provides greater adaptability and modification possibilities in order to weave a special structure at an economical speed.
