Embroidery machine that adjusts the inclination angle of embroidery stitches

摘要

An embroidery data producing apparatus for an embroidery machine which forms embroidery stitches, based on the embroidery data having information about stitch positions comprises a CPU, RAM and ROM. The RAM has a pattern data memory for storing pattern data which represents outlines of a pattern where embroidery will be given, and a embroidery data memory for storing the made embroidery data. The CPU reads the pattern data stored in an external memory device and stores the pattern data in the pattern data memory. The CPU stores the inclination angle input through the keyboard by an operator in the RAM. The CPU sets a pair of facing outlines which extend to a predetermined embroidery executing direction based on the pattern data stored in the pattern data memory. The CPU sets stitch positions on the first outline of a pair of the outlines according to a predetermined thread density. The CPU calculates the straight line which passes through the set stitch position and inclines at set inclination angle toward the embroidery executing direction. The CPU calculates the intersection where the calculated straight line and the second outline of a pair of the outlines intersect, and sets the intersect as a next stitch position following the set stitch position. The CPU stores the stitch positions set on the first outline and the stitch positions calculated on the second outline as the embroidery data in the embroidery data memory.
