Abstract

A sewing system includes a first automatic sewing machine and at least one second automatic sewing machine. The first automatic sewing machine includes a RAM for storing stitch data. The stitch data is processed into data for primarily controlling a needle position, and the data thus processed is stored in the RAM. The first automatic sewing machine further includes a data transmitting device for outputting the processed stitch data to the outside of the sewing machine. The second automatic sewing machine includes a data receiving device for receiving the processed stitch data from the data transmitting device in the first automatic sewing machine. When receiving the processed stitch data from the data transmitting device in the first automatic sewing machine, the second automatic sewing machine starts sewing according to the processed stitch data thus received.
