Background

The face yarn guide bar and the spacing yarn guide bar of the existing double-needle bed warp knitting machine swing back and forth on the latch needle to complete the loop formation. When the knitting machine works, the main shaft rotates for one circle (360 degrees), the face yarn guide bar on the face A finishes one period swing, the first bottom cloth row on the face A is knitted once in a looping mode, and the spacing yarn guide bar is also knitted once on the first row on the bottom cloth on the face A. And so on. Due to the symmetry of the double needle beds, the swing looping time of the face yarn guide bar of the B face differs from that of the A face by a half period, and the interval yarns perform Z-shaped reciprocating swing looping on the A face bottom cloth row and the B face bottom cloth row along with the swing of the interval yarn guide bar to weave the gray cloth.

As the A-side bottom cloth and the B-side bottom cloth are connected by the spacing yarns, the traditional mechanical structure is that a hanging seat is arranged below a cross beam, and a spacing yarn swing arm is fixed in one hole of the hanging seat to swing left and right.
