Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an embroidery sewing machine,
The present invention relates to a method of sticking a piece of applique cloth to a work cloth stretched on an embroidery frame, and a sticking table device used in the method.

[0002]

2. Description of the Related Art When embroidering an appliqué using an embroidery sewing machine, a piece of appliqué cloth is positioned and affixed to a sewn position of a work cloth prior to embroidery processing. Usually, the appliqué cloth piece is attached by pressing the adhesive on the lower surface against the work cloth so as not to shift the position. At this time,
In order to prevent the work cloth stretched on the embroidery frame from being bent by the pressing force, conventionally, as shown in FIG. 20, an operator inserts one arm to the lower side of the embroidery frame 61 and supports the work cloth W with the palm H. Was there. In the figure, 62 is a bed of the embroidery sewing machine.

[0003]

However, according to this method, since the appliqué cloth piece A is stuck on the palm H, the operator is forced to take an uncomfortable posture, and in particular, the large appliqué is applied. In the case of a piece of cloth (for example, a bib number), it takes a considerable amount of time to stick the whole piece uniformly, and there is a problem in that the work efficiency decreases. Further, since the appliqué cloth piece A cannot be pressed too strongly, the appliqué cloth piece A may not be firmly adhered to the work cloth W in some cases.

Therefore, an object of the present invention is to attach a new appliqué cloth piece to a work cloth in a comfortable posture, efficiently, and surely, and to attach the new appliqué cloth piece. To provide a table device.

[0005]

In order to solve the above-mentioned problems, the method of sticking the appliqué cloth piece of the present invention is a work which is detached laterally or forward from the bed and is substantially flush with the upper surface of the bed. Position the work cloth stretched on the embroidery frame directly above the sticking table at the position, place the appliqué cloth piece coated with the adhesive on the lower surface on the upper surface of the work cloth, and use the work table by the sticking table. While backing up from above, the appliqué cloth piece is pressed against the work cloth to be stuck.

After sticking the appliqué cloth piece to the work cloth, it is preferable to move the sticking table from the working position to the storage position where the embroidery frame does not interfere.

Further, the applicator cloth piece sticking table device of the present invention is a sticking table for backing up a work cloth stretched on an embroidery frame from the lower side, and the sticking table is located laterally of the bed. Alternatively, it is provided with a support mechanism that is movably supported at a working position that is separated from the front and has substantially the same height as the upper surface of the bed, and a storage position where the embroidery frame does not interfere.

[0008]

According to the sticking method of the present invention, when the appliqué cloth piece is stuck to the work cloth, the sticking table at the working position backs up the work cloth from below, so that the operator can use his palm. There is no need to support the work cloth, and the appliqué cloth piece can be pressed firmly against the work cloth in a comfortable position. Further, since the working position is laterally or forwardly displaced from the bed, the needle or the like of the embroidery head above the bed does not interfere with the sticking.

Further, if the sticking table is moved from the work position to the storage position after sticking the appliqué cloth piece, the embroidery frame and the sticking table are surely prevented from interfering with each other when the embroidery stitches are formed thereafter. It can be avoided.

These effects can be obtained similarly by the sticking table device of the present invention.
