PATTERN SEWING MACHINE

PROBLEM TO BE SOLVED: To provide a pattern sewing machine which forms disruptive lines, which have a predetermined width in alignment with the sewing line of a pattern design, in a template negative plate such as pasteboard and can simply, quickly, and inexpensively create a template at time of sewing a pattern seam. SOLUTION: All original segments A about the sewing line based on the pattern data of the pattern design are extracted (S12). First, regarding the left-hand side of the sewing line, the left-hand side disruptive line is calculated about each original segment A (S13), intersecting point operational processing is performed (S14), and beginning section extensional operation processing is executed (S15). Next, regarding the right-hand side of the sewing line, a right-hand side disruptive line is calculated about each original segment A (S16), the intersecting point operation processing is performed (S17), and end section extensional operation processing is performed (S18). Finally, profile disruptive line extracting processing is performed (S19) and disruptive line data preparation processing for the template is performed (S21). COPYRIGHT: (C)2008,JPO&INPIT
