Abstract
When two patterns overlap each other and an over stitch block in one of the two patterns divides an under stitch block in the other pattern, a first correction processing is performed so as to divide the under stitch block into two stitch blocks. Then, a second correction processing is performed as follows. A degree of hardening of the stitch embroidery portion resulting from a tightening of the threads of the embroideries in an overlapped portion between the over and under stitch blocks to a workpiece is first determined according to reference directions of the stitch blocks and positions of intersections of the stitch blocks. Then, the higher the degree of tightening, the more the area of the overlapped portion of the under stitch block near the boundary between the stitch blocks is left, whereas the lower the degree of tightening, the more this area is eliminated. Finally, an embroidery frame moving mechanism is controlled according to the corrected stitch data.
