。 It consists of three eccentric cams attached to the upper shaft, a thread payout lever that swings due to the central eccentric cam, and two disc loosening pins that are moved by the eccentric cams on both sides to loosen the thread tension disc. When the side thread tension is open and the downstream thread tension is closed, the thread payout lever swings to let out the upper thread, which is consumed by forming stitches when the upstream thread tension is closed and the downstream thread tension is open. Needle thread feeding device for sewing machines.
