In this article, P represents the distance between the buttonhole; S represents to bend the degree of depth; T is illustrated in the button neck winding process clothes to the distance between the button, claims " finishing height " hereinafter; T1 is illustrated in the operating process of sewing button,, claims hereinafter " neck height " to the distance the button from the center of turning cylinder 220; T2 is illustrated in the button neck winding process, and the center of turning cylinder 220 claims " twining height " hereinafter to the distance between the button; T3 represents the distance between the center of clothes and turning cylinder 220, claims hereinafter " deviant "; B represents the thickness of button; H represents the diameter of buttonhole.

At first, calculate neck height T1 by finishing height T.

If represent for the loop length of finishing height T needs, so by RT:

RT＝2(P+B+T+S+2S’) (1)

Suppose that wherein S ' is substantially equal to S.

In button sewing process, total loop length is:

P - H + 2 B + T 1 + \sqrt{(P . H / 2 S)^{2} . {(T 1 . S)}^{2}} - - - - (2)

Determine that equation (1) equals equation (2):

RT = P - H + 2 B + T 1 + \sqrt{(P . H / 2 S)^{2} . {(T 1 . S)}^{2}}

If set X=RT-P+H-2B, and Y=P-H/2-S, so above-mentioned equation is:

X . T 1 = \sqrt{Y^{2} . {(T 1 . S)}^{2}}

Both sides square:

T 1 = \frac{X^{2} . Y^{2} . S^{2}}{2 (S . X)} - - - - (3)

Adopt equation (3), can obtain neck height T1 from the given height T that finishes.By mobile button dop 21 entry altitude position T1, suitable neck height T1 can be set.

Secondly, the displacement D between neck height T1 and winding height T2 can calculate by following equation:

D=T1-T2, and T2=T-T3 (4)

T1 in the place of equation (3) can obtain above-mentioned displacement D according to the given height T that finishes.

Button dop 21 is moved a displacement D from neck height T1, twine in the sewing process at neck, dop 21 is designed to be positioned at and twines height and position T2, so that twine in the sewing process at neck, the height from clothes to the button forms finishes height T.If in the Sewing machines of this embodiment, button dop 21 swings to winding position simply, twines the sewing process at neck, owing to there is deviant T3, the distance between from clothes to the button is greater than neck height T1, and this will cause neck with the clothes pull-up.
