An embroidery data processing system controls an automatic sewing machine to produce an embroidery design having a blurred side or blurred boundary line between adjacent blocks which make up the embroidery design. The embroidery data processing system includes a first memory storage area for storing side information indicating sides of each of the blocks, a second memory storage area for storing thread density information indicating the thread density of stitches to be formed in said each block, a third memory stoage area for storing in/out patterns indicating how stitching points are to be displaced with respect to the sides of a selected one of the blocks, which are indicated by the side information, and a controller for calculating stitching points depending on the thread density information along the sides of the selected block according to the in/out patterns, and for calculating stitching points depending on the thread density information along the sides of another block than the selected block, which are indicated by the side information. The third memory storage area may store in/out patterns indicating how stitching points are to be displaced with respect to the sides of said each block which are indicated by the side information, and the controller may calculate stitching points depending on the thread density information along the side of said each block according to the in/out patterns.

Embroidery data processing system for automatic sewing machine

Desired individual letter codes indicative of letter to be stitched on a piece of cloth by a sewing machine are selected and entered in relation to the character stitching sequence through a keyboard. Then, character identification codes are constructed according to a predetermined stitching sequence based on the entered individual letter codes and stored outer profiles. Stitch pattern data corresponding to the constructed character identification codes are read out from a memory, and used to control the sewing machine to produce the desired letters having different outer profiles.
