ABSTRACT:
A curved edge sewing system sews a curved edge of a cloth, such as a curved edge of a fly. The curved edge sewing system has a cloth support table, and a sewing needle located at a sewing position relative to the cloth support table. A cloth presser device moves towards and away from the cloth support table and rotates relative to the sewing needle. A first driver is operatively connected to the cloth presser device and moves the cloth presser device towards and away from the cloth support table. A second driver is operatively connected to the cloth presser device and rotates the cloth presser device relative to the sewing needle. A controller has a first signal supplied to the first driver and actuates the first driver, and a second signal supplied to the second driver and actuates the second driver.
