Description of the Related Art In the case of producing clothing, first, after the overall shape of the clothing is designed, basic patterns such as front and rear body parts, sleeves, etc. are used by a well-known method so as to correspond to the design. Change (grading). This basic pattern shape is generally stored in the storage device of the apparel CAD system, and the pattern (pattern) surrounded by the finish line is displayed on the display of the apparel CAD system.
Has been edited as the shape of.

Further, the pattern is added with a seam allowance for stitching the pattern with another pattern. Then, the material cloth is cut into a pattern shape with the seam allowance, and the cut cloth is sewn together by a sewing device to produce a garment.

In recent years, such sewing is performed by a pattern seamer (automatic sewing machine) which operates based on the sewing data relating to the finish line. The pattern seamer is configured to sandwich a cloth or the like as a workpiece and to relatively move the sewing needle and the cloth to perform stitching. In the plate-shaped clamp plate that holds the cloth, a guide groove that is hollowed out along the path of relative movement is formed so that the sewing needle can penetrate the cloth.

Conventionally, in order to create a guide groove of a clamp plate corresponding to a sewing method of a pattern, the shape data of the pattern processed by an apparel CAD system or the like is not directly used, but is printed on the paper surface by the apparel CAD system. Based on the shape of the drawn pattern, the operator manually copies the shape of the reference groove of the guide groove onto the clamp plate by hand, and then based on the copied shape and the sewing method, I thought about the shape myself, and then hollowed out that part with a machine tool.

[0006]

However, if the operator manually copies the required shape or forms the shape of the cutout portion which becomes the guide groove in this way, not only the working efficiency is poor, but also the cutout portion When creating a shape, it tends to be inaccurate, especially in the case of curved parts,
As a result, the actual sewing line was changed, and there was a problem that the finish was not as planned.

The present invention has been made to solve the above-mentioned problems, and it is possible to improve the efficiency and accuracy of the work for creating processing data for processing a portion of a clamp plate through which a sewing needle passes to the clamp plate. It is an object of the present invention to provide a processed data creating device.

[0008]

In order to achieve this object, an apparel CAD system of the present invention uses a sewing needle based on designating means for designating the shape of a pattern and shape data corresponding to the shape of the specified pattern. And a data creating means for creating processing data of the needle passing portion of the clamp plate used in the sewing device in which the clamp plate of the work cloth is relatively moved in accordance with a desired sewing process.

[0009]

In the apparel CAD system of the present invention having the above construction, the designating means designates the shape of the paper pattern. The data creating means is a needle of a clamp plate used in a sewing machine in which a sewing needle and a clamp plate of a work cloth are relatively moved in accordance with a desired sewing process based on shape data corresponding to a specified pattern shape. Automatically create processing data for the passing part.
