The working width of the modern tricot warp knitting machine has also increased further. Although the 130-inch (3302mm) width machine is still in production and use, most of the newly produced Tricot warp knitting machines have adopted 170-inch (4318mm) width machines. Currently, the highest machine width has reached 260 inches (6604mm).
As the machine width increases, the machine's operating speed decreases accordingly. In addition, larger machine widths and adjustments are more complicated and difficult. On these machines, in order to support the main shaft and the bed of the ring-forming machine, 10 to 12 bearings are required, and the transmission of each of the coil-forming parts is realized by 5-6 sets of the same mechanism.
This puts higher requirements on the manufacture and adjustment of these institutions, otherwise the load on each mechanism will be inconsistent, and in severe cases, the bed of the coiled parts will be distorted. Machines with larger widths are more sensitive to temperature changes, and have higher requirements for temperature and humidity in the workshop. The loss of productivity during parking is correspondingly larger than that of machines with narrow width.
However, a machine that is twice the width of the narrow width is less expensive than the two narrow-width machines, and the cost of the finished fabric is less than 20%, or even more, and the floor space is much smaller. In addition, the width of the fabric produced by the wide-format machine is flexible, easy to meet the cutting requirements, and can reduce the loss during cutting. In summary, the wide-format Tricot warp knitting machine has been widely used for mass production and has been widely used.
