  • Publication number: 20200233994
    Abstract: The virtual shape of knit product comprising plural parts and mutually divided in the knit data is simulated. The connection information regarding how said parts are mutually connected is obtained based upon the knit data or the pattern data of the knit product, and the plural parts are mutually based upon the obtained connection information. The virtual shape of the knit product is deformed by deforming the plural parts according to the forces acting on the plural parts. At least one of the plural parts is stretched automatically or according to at least an instruction by a user, and then, the virtual shape of the knit product is re-deformed to a natural shape by re-deforming the plural parts according to the forces acting on the plural parts. Then, stitches are allocated within the plural parts, and the allocation of the stitches is smoothed within the plural parts.

  • Patent number: 10145041
    Abstract: A method for knitting a shoe upper capable of forming a new stretch preventing section different from a conventional stretch preventing section, and a shoe upper obtained through such knitting method are provided. The shoe upper including a base knitted fabric portion (1F) that covers a foot of a wearer is knitted. In the knitting, a stretch preventing section (20) configured by a knitted fabric of a plain structure is knitted, where one end in a wale direction is connected to the base knitted fabric portion (1F) and another end in the wale direction is not connected to the base knitted fabric portion (1F). The stretch preventing section (20) in which one end is fixed and the other end is not fixed is curled to a tubular shape. The curled stretch preventing section (20) is thicker than the other portions, thus suppressing the stretch of the shoe upper.
