Embroidery sewing system

The disclosure presents an embroidery data processing device and a computer program product capable of creating a single unit of tree structure vector data by coupling plural pieces of independent tree structure vector data. A coupling node is added between nodes and of a tree structure vector data, and a vector data to for coupling nodes and, and a vector data to for coupling nodes and are created, and thereby a tree structure vector data is created. In a tree structure vector data, the node mutual direction is converted so that the node existing at the connecting position may be a root node, and a tree structure vector data is created, and this root node is coupled with the coupling node of the tree structure vector data, and a single tree structure vector data is created.

Embroidery data processing device and computer program product

The disclosure presents an embroidery data processing device and a computer program product capable of tearing off an elastic sheet easily after an item of embroidery has been sewn, thus enhancing working efficiency. A CPU extracts a contour line from needle drop points PN (N=1, 2, . . . , n) stored in embroidery data (Sto S). When the CPU judges that each needle drop point QN on the contour line is separated from an adjacent needle drop point Q (N+1) by more than a specified distance, the CPU forms needle drop points between adjacent needle drop points QN and, Q (N+1) separated from each other by more than a specified distance, reads out from a ROM tearing stitch data for forming a stitch of satin stitching different in stitch width in an inside direction of an embroidery region, and adds the tearing stitch data to the embroidery data so that a sewing sequence of stitches of satin stitching is ahead of a sewing sequence of stitches of the embroidery pattern main body in the embroidery region (Yes at Sto S).

The disclosure presents a quilting data processing apparatus and a program capable of displaying changes of fabric caused by a sewing line, and or easily displaying a visual image of a finished state of quilting. The CPU receives the fabric pattern of quilting, the thickness of fabric, the thickness of elastic material, and the sewing line of quilting, and, when the preview button is pressed, creates a basic mesh pattern, calculates the total deformation degree, deforms the basic mesh pattern sequentially along the sewing line to a deformation degree commensurate with the total deformation degree, and deforms each mesh adjacent to deformed meshes commensurately with the deformation degree, thereby creating a deformation mesh pattern (Sto S). Consequently, the CPU adheres to each mesh the fabric pattern displayed in a specified size in accordance with the deformation mesh pattern so as to create deformation fabric image data, overlaps the sewing line data to the upper side of the deformation fabric image data, and displays as a quilting pattern (Sto S).

Quilting data processing apparatus and computer program product
