  • the design system for a knitted fabric 100 of the present invention decides a knitting method in the different-gauge area by a different-gauge-area knitting setting part 51 included in the pattern data editing means 5, and decides a knitting method in a border portion between the different-gauge area and the initial-gauge area by a border-area knitting setting part 52 included in the pattern data editing means 5 to create the knitting program by the knitting program creating means 8, based on these types of information.
  • a creation procedure of the knitting program is described with reference to the block diagram of Fig. 1 and a flowchart of Fig. 2 .

  • the different-gauge-area knitting setting part 51 specifies a number of the different-gauge knitting units in the different-gauge area and the position information, from the initial-gauge information and the different-gauge information (step 3).
  • the different-gauge-area knitting setting part 51 decides how to perform the knitting in the different-gauge area. For example, the different-gauge-area knitting setting part 51 determines whether a difference in size between the initial-gauge knitting unit and the different-gauge knitting unit is not less than a predetermined value (step 4), and decides whether knitting in step 5-1 is to be performed, or knitting in step 5-2 is to be performed, which steps are described next.
  • This predetermined value may be a fixed value inputted in advance, may be a correction value resulting from automatically correcting this fixed value with reference to information of the knitting such as a size of a knitting yarn, or may be changeable by an operator.

That is, four knitting needles are used to execute the knitting code of knit set for the different-gauge knitting unit.
  • the knitting code of knit is set for the initial-gauge knitting unit in the initial-gauge area
  • the number of the knitting needles used to execute the knitting code of knit is one. For example, if the whole needle knitting is performed in the initial-gauge area, the knitting method is changed so that half gauge knitting is performed in the different-gauge area.
  • the different-gauge knitting unit is larger than the initial-gauge knitting unit
  • the number of knitting needles used to execute the knitting code set for the different-gauge knitting unit may be made smaller than the number of needles used for the initial-gauge knitting unit for which the same knitting code is set.

  • the loop length of the stitch can be changed. For example, when the different-gauge knitting unit is larger than the initial-gauge knitting unit, the drawing amount of the knitting needle is made larger, and when the different-gauge knitting unit is smaller than the initial-gauge knitting unit, the drawing amount of the knitting needle is made smaller.
  • the border-area knitting setting part 52 of the pattern data editing means 5 accesses knitting method data of the border portion (step 6) to decide a knitting method in the border portion between the initial-gauge area and the different-gauge area (step 7).
  • the knitting method data of the border portion is an aggregate of publicly known knitting methods stored in storage means (not shown) inside the design system for a knitted fabric 100, and the border-area knitting setting part 52 decides an optimal knitting method from the aggregate of the knitting methods with reference to the initial-gauge information, the different-gauge information and the knitting method for the different-gauge area.
  • the knitting method for matching the numbers to each other is mainly selected.
  • the size of the different-gauge knitting unit in the course direction is equivalent to the two initial-gauge knitting units.
  • two adjacent stitches are overlapped on a stitch row in the initial-gauge area lining up in the border portion, thereby forming double stitches so that the number of stitches in the course direction of the initial-gauge area matches the number of stitches in the course direction of the different-gauge area, and stitches of the different-gauge area are knitted on these double stitches.
  • stitches in a stitch row of the different-gauge area lining up in the border portion are split knit so that the number of stitches matches the number of stitches of the initial-gauge area, and the stitches of the initial-gauge area are knitted on these split stitches.
  • the number of stitches lining up in the border portion between the initial-gauge area and the different-gauge area can be the same, and thus, at this time, the adjustment of the number of stitches in the border portion may not be performed.
  • the border-area knitting setting part 52 selects the knitting method for the border portion so that no kink, slack and the like are caused in the knitted fabric by the difference in the number of courses. Every how many courses the initial gauge area and the different-gauge area are to be connected is decided in accordance with a ratio between the initial-gauge area and the different-gauge area. In the case shown in Fig. 4 , one course of the different-gauge area is connected with respect to two courses of the initial-gauge area.
  • the knitting program creating means 8 creates the knitting program in which actual motions of the knitting needles, a feeding procedure of the knitting yarn, and the like are set, based on these knitting codes (step 8).
  • the created knitting program is sent to a flat knitting machine via a storage medium such as a magnetic disk, a cable, a wireless or the like.
  • a relationship between the initial-gauge area and the different-gauge area is taken as an example, by utilizing a concept to decide the knitting method in the different-gauge area and the knitting method in the border portion where the gauge differs, which are shown in this flowchart, two or more different-gauge areas different from the initial gauge area can also be set.
  • the knitting methods in the different-gauge areas may be decided with reference to the initial-gauge knitting units.
  • the knitting methods in border portions where the gauge differs may be decided with reference to the initial-gauge knitting units.
  • the knitting method for the border portion between one of the different-gauge areas and the initial-gauge area is decided with reference to the initial-gauge knitting units, the knitting method for the border portion between the one different-gauge area and the other different-gauge area is also indirectly decided with reference to the initial-gauge knitting units.
  • the processing described above is executed inside the pattern data editing means 5, and although the pattern data having the initial gauge and the different gauge (multiple-gauge pattern data) as shown in Fig. 4 is displayed on the display means 7 in order to make it easy to design the knitted fabric on the assumption of the finishing, inside the pattern data editing means 5, there exists data of the pattern data expressed by a single gauge (single-gauge pattern data) as shown in Fig. 5 .
  • a configuration may be employed, in which by a displaying switchover command means not shown (e.g., an icon displayed on the display means 7 or the keyboard), switchover between the display with the plurality of gauges and the display with the single gauge is commanded to the display processing means 6.
