Abstract
An apparatus for processing embroidery data utilized by a sewing machine for forming zigzag stitches, including a first and a second memories for storing point data indicative of positions of a series of points and a width of zigzag stitches. The apparatus further includes a producing device for, by utilizing the point data and the width data, determining a first and a second virtual line for each of line segments each of which connects between a corresponding one of pairs of adjacent two points out of the series of points, such that the first and second virtual lines are parallel to the each line segment and are spaced apart from each other by the width, and producing block data representative of a trapezoid bounded by a first and a second base parallel to each other and a first and a second leg which are not parallel to each other.
