Abstract
An automatic thread cutting device for cutting upper and lower threads in motorized and/or computer-operated embroidery and sewing machines. The thread cutting device includes a fixed knife for the upper thread and a movable knife for the lower thread. The movable knife includes a deflector for making the upper thread taut and cutting surface for actually cutting the lower thread. After the lower thread is cut, the movable knife is withdrawn and the upper thread is relaxed so that it can be cut by the fixed knife.
