  • Patent number: 6341570
    Abstract: A method of sewing the toe of a sock is provided which can automatically take out a sock pattern of knitted fabric from a sock knitting machine and sew up the selvedge at the toe portion of the sock pattern of knitted fabric thus improving both the efficiency of production and the energy saving. When a sock pattern of knitted fabric has been fabricated by the sock knitting machine, the transfer needles mounted on a group of transfer needles equipped movable tables are advanced at their tips close to the hooks of knitting needles. Then, the sock pattern of knitted fabric is lifted up and turned inside out by suction to transfer its loops at the toe portion from the knitting needles to the corresponding transfer needles. As a result, the sock pattern of knitted fabric turned inside out is transferred from the sock knitting machine to the transfer needles equipped movable tables.
