Abstract: An automatic circumferential insertion apparatus and method for a complex rotary preform. The apparatus includes a double-hinge yarn carrier and a U-shaped bracket. Two ends of the double-hinge yarn carrier are respectively provided with a cylindrical hinge structure. One cylindrical hinge structure is in revolving pair connection with an outer clamping buckle at one end of the U-shaped bracket, and the other cylindrical hinge structure is in revolving pair connection with an inner clamping buckle at the other end of the U-shaped bracket. Two sides of the U-shaped bracket are provided with an electromagnet, respectively. The outer clamping buckle is provided with a pin, which is controlled by triggering, and is triggered simultaneously with the electromagnet at the side where the outer clamping buckle is arranged.
