Embodiment Construction

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] According to a first aspect of the present invention, the present invention provides a method for sewing fancy stitch seams using fabrics capable of changing and adjusting the pitch of the fed fabrics on a stitch-by-needle (stitch) basis A fancy stitch sewing method used in an electronic zigzag sewing machine that forms stitches on a cloth by cooperating with a feeding device and a needle oscillating mechanism that oscillates the needle in a direction intersecting the feeding direction of the cloth.

[0041] First, the direction of the present invention is defined. It can be understood that the definitions of these directions are only used to understand the present invention and should not limit the present invention.

[0042] The above cloth feeding direction is Figure 5 Y-axis direction shown. More specifically, along Figure 5 The positive Y-axis direction...

Abstract

The invention relates to a sewing method of a fancy stitch seam and an electronic sawtooth sewing machine, relates to the technical field of sewing machines, and is used for solving the technical problem of pattern breakage caused by reverse feeding interval error or missing sewing. According to the fancy stitch seaming method, the first forward feeding interval is larger than the second forward feeding interval, and the reverse feeding interval is larger than the second forward feeding interval, so that in each step, in the feeding direction of the cloth, the fancy stitch seaming distance is larger than the first forward feeding interval, and the fancy stitch seaming distance is larger than the second forward feeding interval. The position at which the needle is dropped according to the reverse feed pitch is always located in front of the position at which the needle is dropped according to the first forward feed pitch, so that even if a feed pitch error or needle shake of the same level as in the prior art occurs, pattern cracking does not occur. Therefore, the technical problem that in the prior art, due to the fact that the distance of reverse feeding is wrong or sewing is missed, patterns are broken is solved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing method for fancy stitch seams and an electronic zigzag sewing machine. Background technique [0002] like figure 1 As shown in the figure, the existing fancy stitch sewing method is to drop the needles at positions 1, 2, 3 and 4 by swinging the needle left and right, so as to form the fabric on the left side and the fabric on the right side. For fancy stitches, the forward feed distance A' and the forward feed distance B' are roughly the same, while the reverse feed distance C' is slightly larger than the forward feed distance B'. like figure 2 shown, showing normal stitches in the prior art. [0003] However, the above-mentioned sewing method is prone to the following problems. That is, when the pitch of the reverse feed is wrong or the needle is easily jittered when sewing is omitted, the needle drop of the reverse feed becomes smaller than that of the need...
