Description

1231324 V. Description of the invention (1) [Technical field to which the invention belongs] Knitting warp knitting machine can manufacture jacquard, and this solution is only conditionally suitable. The instability of all line demand here is not consistent. Therefore, all the lines can no longer be treated in the same way. Therefore, each thread has its own tension spring and guide device. In principle, each thread can be handled individually to adjust the instability of the thread. Here the spring is a steel spring, which is problematic when the warp knitting machine is accelerated. 2. [Previous Technology] Using a steel leaf spring (cross-section 0.60 mm²), the frequency is relatively low, and uncontrollable motion may occur. Using a leaf spring with a cross section of 0.80 mm2, the frequency is high enough. Deflecting such a spring requires a lot of force, and the great way of spring tension is too high. Uncontrollable movement and too much spring tension can lead to an unclean fabric image. 3. Summary of the Invention The content of the present invention is a knitting warp knitting machine. The machine has a warp knitting range, a wire range, and a thread tension device. The device is located between the warp knitting range and the wire range. There is a tension spring and a guide device. The knitting warp knitting machine has long said that the form of the thread is not consistent. Due to the movement of warp knitting elements, the line of demand for each warp knitting cycle is not stable. However, at the same time, the warp beam (from which the wire is pulled out) should be turned as uniformly as possible. As the demand for the thread is unstable, there is the formation of an extended line (invalid gauze). The length of the distance between the wire range and the warp knitting range can be changed. In this way, the instability of the thread demand is adjusted.
