implanting lacing wire pieces, folding the four lacing wire pieces into a V shape, implanting the lacing wire pieces between the left piece of membrane and the upper piece of membrane and between the right piece of membrane and the upper piece of membrane and the lower piece of membrane from the left side and the right side, and performing point ironing pre-fixing on the contact positions of the two side edges of the four lacing wire pieces and the four pieces of membranes;

performing full-ironing edge sealing on the positions, in contact with the four films, of two side edges of the four lacing bar pieces from the inner sides of the openings of the left and right films, above the upper film and below the lower film;

and (5) cutting at a fixed length, staggering the positions of the lacing wire sheets, and cutting the continuous body with the edge sealed at a fixed length to form a cylindrical lacing wire bag.
