As described above, in the prior art, since the binding fitting is twisted after the binding fitting is supplied, the binding fitting supply device is idle during the twisting, and the binding fitting is idle. The twisting device of the binding fitting is idle until it is supplied, which is a waste of time. Moreover, when the binding metal fitting is twisted, the binding metal fitting is shortened by the twisting, a force pulling the binding portion downward is generated, and the binding metal fitting is cut. In order to avoid this, it is necessary to move the twisting device upward, but the device becomes complicated and control is difficult because the movement amount varies depending on the wire diameter or the number of twists. Further, in the conventional method, since it is not possible to select the intersecting position, an unnecessary place is fixed, or the binding strength of the frame body is low after binding because the inserting direction of the binding metal fitting is one direction. Furthermore, there is a problem that a skilled worker who handles the binding device is required.
