ABSTRACT:
An embroidering sewing machine which is electronically controlled is described, wherein a plurality of addresses of stitch data for controlling the stitching operation are divided into a plurality of blocks each of which comprises N number of stitch data each of which is successively elected as the initial stitch data of each block and provides a distance between the adjacent stitches. The speed of the vertical movement of the machine needle is decided by setting a specific rate of speed corresponding to the maximum rate of distance of each block. The number N may be optionally selected to avoid the abrupt change of speed which may otherwise occur depending upon the embroidery patterns to be stitched.
