ABSTRACT:
A threading device comprising a stretching member, a moving member, a threading member and an actuator. The actuator receives threading instructions and drives the moving member. The moving member moves the thread stretched by the stretching member to the front or the rear of the eye in the needle. The threading member threads the eye with the thread positioned in front or at the rear of the eye. The actuator can thus control the movement of the moving member. The thread can securely be positioned in a given position in front or at the rear of the eye, and the threading member can accurately thread the eye in the needle.
