BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery sewing machine, and more particularly to an embroidery sewing machine capable of applique sewing.

[0002]

2. Description of the Related Art The procedure of applique work by an embroidery sewing machine will be briefly described. To perform applique sewing with the embroidery sewing machine,
The applique cloth material set in the embroidery frame is provided with pattern data for forming a seam serving as a mark for cutting out the contour of the applique cloth, and the applique cloth (hereinafter referred to as the base cloth) set in the embroidery frame. Pattern data for forming a seam which is a mark of a position where the applique cloth is fixed, and the cut applique cloth is temporarily fixed to the position of the mark on the base cloth, sewn by applique sewing, and an applique is created. Applique sewing data for performing sewing is stored.

The procedure of applique work is as follows. First, an applique cloth material is set on an embroidery frame, a seam is formed as a mark for cutting an outline, the applique cloth material is removed from the embroidery frame, and the applique cloth material is cut along the mark. Cut out the contours of the applique cloth from.

[0004] Next, the base cloth is set on an embroidery frame, stitches are formed as marks for the position where the applique cloth is fixed, and then the applique cloth whose outline has been cut is temporarily fixed at the mark position of the base cloth, and then embroidered. The applique work is completed by sewing the applique cloth to the base cloth by applique sewing of the sewing machine, removing the sewing machine from the embroidery frame after completion of sewing, and removing the crossover thread of the seam.

[0005] When an applique work is performed by an embroidery sewing machine, it is necessary to temporarily fix the applique cloth to the base cloth in a process in the middle of the applique work. Conventionally, the applique work was performed by applying an adhesive to the back side of the applique cloth and temporarily fixing the applique cloth to the base cloth, and then sewing the applique cloth to the base cloth using applique stitches. As the adhesive for temporary fixing, there are used, for example, a starch glue, a work glue, and a vinyl acetate resin-based adhesive for sticking cloths together by dressmaking or the like.

[0006]

The application range of the adhesive for temporarily fixing the applique cloth and the base cloth in the process of the above-mentioned applique work using the conventional embroidery sewing machine depends on intuition. As a result, in some cases, the adhesive was also applied to the needle drop position of the applique stitch by the next embroidery sewing machine.

Therefore, when applique sewing is performed by an embroidery sewing machine, the first problem is that when the adhesive is freshly dried, the adhesive applied to the sewing thread and the upper thread guided by the sewing needle penetrating the applique cloth and the base cloth. In some cases, the formation of the upper thread loop is hindered, which causes the occurrence of skips and a problem that a preferable applique sewing operation cannot be performed. Therefore, a solution to this problem has been desired.

[0008] As a second problem, when the adhesive is hardened, the sewing machine needle which penetrates the applique cloth and the base cloth, or the needle or the upper thread which breaks the upper thread guided by the sewing machine needle can be used. There was a problem of adverse effects on the system, and a solution to this problem was desired.

In order to avoid the first and second problems described above, it is necessary to accurately determine the application range of the adhesive to the base cloth. However, conventionally, trial sewing of applique sewing has been performed.
The exact application range of the adhesive was determined by time-consuming trial and error.

[0010] The problem to be solved by the present invention is to ensure that the application range of the adhesive is accurately applied to a position avoiding the needle drop point of the sewing machine needle during the sewing operation of applique sewing. Prevents the first and second problems of skipping of eyes and solves problems such as adverse effects on the sewing needle and upper thread, and produces beautiful applique works with simple operation and quickly. It is to provide a possible embroidery sewing machine.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems in the prior art, the present invention provides a embroidery sewing machine for forming a stitch as a mark for cutting the contour of an applique cloth from an applique material cloth. 1 pattern data, second pattern data for sewing the applique cloth temporarily fixed to the base cloth to the base cloth by the seams of the applique sewing, and a first guide position for setting the applique cloth on the base cloth. The first guide pattern data for forming the stitches and the stitches at the first guide position have a fixed positional relationship, and the stitch position of the applique stitches on the base cloth is avoided. A stitch that can be used for applique sewing, in which guide pattern data including second guide pattern data for forming a stitch at a second guide position for guiding the application range is stored. There is provided a sewing machine,

This makes it possible to produce beautiful applique stitched works using an embroidery sewing machine quickly and easily.

[0012]

The first effect of the embroidery sewing machine according to the present invention is to set an applique cloth, whose contour has been accurately cut from an applique cloth material, at an accurate position on the base cloth prior to applique sewing by the embroidery sewing machine. There is an effect.

As a second operation, when sewing an applique cloth to a base cloth by a sewing machine by applique sewing, a trial-and-error effort such as trial sewing is conventionally required to determine an application range of an adhesive. And an effect that applique work can be performed.

A third effect is that the adhesive applied using the second guide position as a mark does not adhere to the sewing needle and the upper thread that penetrate the applique cloth in the case of fresh drying. This has the effect of preventing the occurrence of blind spots due to the adhesion of the adhesive.

As a fourth action, even when the adhesive is hardened, the sewing machine needle penetrating the applique cloth and the base cloth is damaged or the upper thread guided by the sewing needle breaks as in the conventional case. This has the effect of preventing problems.
