Description

Detailed Description of the Invention The present invention provides variable values based on trial knitting samples or experience that take into account the thickness of the knitting yarn, the density and density of the knitting structure, etc., such as the "number of stitches" per 10 cm in width, "Number of steps"
is entered as the gauge designation value using the numeric keypad, and based on that, the body width is entered in the knitting drawing.
The reduction of straight lines or curves based on the actual size values of body height, curves of the reduced and increased parts, diagonal straight lines, etc., the dimension values determined from drawings, and the reduction and increase values necessary for practical skill of the increased parts. or calculate the numerical values of the "number of stitches" and "number of rows" of the whole or part of the knitted fabric, and visually output the calculated numbers as described above using a printer or other display device so that they can be used for practical knitting skills. This invention relates to a knitted fabric drafting index calculator.

When braiding a knitted fabric, the knitting fabric drawing 101 illustrated in FIG. 1 is usually performed. However, practical knitting techniques involve reducing and increasing stitches, and (1) When knitting is performed while reducing stitches, () The type of knitting is performed by reducing stitches in a concave arc shape (Figure 2 A) () There is a type in which the stitches are knitted in a convex arc shape (Fig. 3 A) () A type in which the stitches are knitted in a diagonal straight shape (Fig. 4 A). () Type where the stitches are increased in a concave arc shape (Figure 5 A) () Type where the stitches are increased in a convex arc shape (Figure 6 A) () Type where the stitches are increased in a diagonal straight line There is a type (Fig. 7 A) that is knitted together. In addition, there are () a type that only determines the number of stitches in the width direction (a) (Figures 1 and 8 A), () a type that only determines the number of rows (b) (Figures 1 and 9 A), etc. All of this must be combined to perform practical skills such as increasing/decreasing knitting needles and determining the number of rows (symbols a, b, c, and d in Figures 2-A to 9-A have been conventionally used in knitting drafting. , a is the length in the direction of the number of stitches at the dimension location where the stitches are to be reduced or widened, b is the height in the direction of the number of rows at the same location, c is the height of the arc, and d is the knitted fabric whose left and right sides are symmetrical in most cases. This is the length in the direction of the number of stitches from the center to the place where the stitches are to be reduced or widened.
- Units are cm -).

However, the knitting drawing 101 can only be calculated by showing dimensions such as the actual knitting width, the actual knitting length, and the positions of decreases and increases, or by visually measuring the grid, and cannot be calculated by taking into account the thickness of the knitting yarn, the density of the stitches, etc. Even if the number of stitches or rows per unit dimension is known through trial knitting or experience, each row to several rows necessary for practical knitting skills can be determined based on the dimensions written in the knitting drawing 101. Not only does it require a high degree of skill to calculate the number of increases and decreases, but if there is a miscalculation in the calculation, the knitting operation itself must be redone.

The present invention provides these indexes, especially the above ()
- In (), reduced stitches in each row or every several rows,
Alternatively, it is possible to calculate the number of stitches in the required part and the number of rows from the required part to the required part, visually output it on a printer or other display device, and easily execute the stitch increase/decrease operation in knitting practical skills performed with reference to the knitting drawing. It is intended to do so.
