Abstract

A weft knitting machine capable of inserting a warp which is a weft knitting machine that feeds a warp to a knitting needle only from a needle bed on one side, and which can knit a fabric by using a warp even with a knitting needle from a needle bed on the other side without requiring an extra yarn guide. A knitting method in such a weft knitting machine is also provided. When the hooks (19) of five knitting needles (17) are made to advance from a rear needle bed (23) to between the knitting needles (16a, 16b) of a front needle bed (22), a purl can be knitted by these five knitting needles (17). The knitting needles (16a, 16b) may not be made to advance from the front needle bed (22) to a tip part (20) one by one. Alternatively, a texture such as rib and links can be knitted using a knitting yarn which is fed as a warp by making the knitting needle (16) advance from the front needle bed (22) to the advancing range of the knitting needle (17) from the rear needle bed (23).
