Description

Technical Field

[0001] The patent of this invention relates to a knitting needle and a flat knitting machine needle plate combination. Background Art

[0002] With the continuous development of textile technology, flat knitting machines are increasingly used in the textile field. Flat knitting machines are equipped with a needle plate with parallel slots milled on it. Inserts are installed in the slots. Structural components such as tooth plates, sinkers, and inserts are installed at the front of the slots. Every two adjacent inserts form a needle slot, in which knitting needles are placed.

[0003] As people's taste for fabrics continues to improve, there is a particular demand for fabrics knitted by fine-gauge machines. The definition of the existing flat knitting machine gauge is the number of needles contained in one inch. The higher the number of needles, the smaller the gauge. When the thickness of the insert remains unchanged, the needle groove formed between each adjacent insert "will become relatively smaller". The set thickness of the knitting needle can only be smaller than the size of the needle groove, resulting in a weakening of the knitting needle rigidity. When the gauge becomes smaller, the height of the set knitting needle elastic expander and the needle body also becomes smaller accordingly, which makes it difficult to insert the needle head of the knitting needle, seriously affecting the smooth progress of the turning needle action.
