general sewing machine

General-purpose sewing machines mainly include industrial flatbed sewing machines. These machines are primarily used for flat sewing, and with technological advancements, they are evolving towards higher speeds and computerization. For example, machine speeds have increased from 3000 rpm to 5000-6000 rpm, and they also feature multiple safety functions such as automatic reverse sewing, automatic thread trimming, automatic thread feeding, automatic presser foot loosening, and automatic needle position control.
