Device for controlling finish-up stitching in an electronic computer sewing machine

摘要

Stitching coordinates prior to finish-up stitching are used to produce finish-up stitching data, resulting in undistorted stitching in all cases. Also, stitching data is pre-read out at start-up for stitching patterns continuously and predetermined stitching coordinates are obtained from the stitching data for making initiating finish-up stitching data. Therefore, it is no longer necessary to store the finish- up stitching data or the initiating finish-up stitching data in advance in a programming memory (ROM) so that operating efficiency of the sewing machine is increased.
