Briefly describe the development of socks machine

Sock knitting machine, the first knitting machine invented by the British Lee in 1589, which uses crochet to produce shaped socks to produce socks.
Basic Information
Knitting machine for the production of socks.
In 1589, the British W. Lee invented the first knitting machine, and used crochet to produce shaped socks. In 1849, the single needle circular socks machine appeared as the tongue needle began to be used in small caliber circular machines. * The first production of tailored socks. It was not until 1857 that weaving socks with a bag-shaped heel and a toe. In 1864, the British W. Cottonton invented the Cottonton socks machine (crochet flat knitting machine). In 1900, double-cylinder circular socks machines and knitted rib socks were introduced as double-headed tongue needles were applied to small-caliber circular machines. The hosiery mouth can be knitted by a special machine of the hosiery machine, or transferred to the hosiery machine manually after finishing by other machines. Hosiery, high heels, heels, socks (including soles and socks), reinforced loops and socks are knitted by socks machines.

Sock machine classification Sock machine can be classified according to the type of needle bed, the type of knitting needle and the number of cylinders (beds). The flat-knitting machine has a high machine number and produces flat-knitting pieces that change the width of each section according to the shape of the feet and legs, and are stitched into stitched socks. The circular sock machine has a wide range of machine numbers. The production of tubular socks is based on changing the size of the loop of each section, or using elastic yarns, or weaving toe socks and heels to adapt to the shape of the foot. The sock head of the tubular sock blank is closed to form a seamless sock. The production efficiency of flat socks is relatively low. At present, round socks are widely used. Sock machine structure The circular socks machine is mainly composed of yarn feeding mechanism, knitting mechanism, needle selection mechanism, control mechanism, transmission mechanism, density adjustment mechanism and pulling mechanism. Some socks machines also have lifting and folding mechanisms. The flat socks machine still has a transfer mechanism.
The function of the yarn feeding mechanism is to pull the yarn out of the package into the knitting area. There are two types: negative and positive. The passive yarn feeding is to pull the yarn out of the package by the tension. Although there are tensioners and tension compensation devices to control the tension and the amount of the yarn, the difference in yarn tension is still large. The positive yarn feeding method uses a special device to feed the yarn into the knitting area at a constant linear speed, and the yarn tension difference is small.
