Since the wire 1 is restrained by the support rod 2b, smooth rewinding may not be performed, and
There is a risk that some of the parts will be forcibly twisted and a so-called kink will occur. Further, the wire may be inadvertently bent by being pulled out by a large force, and may be twisted and kinked. If the kinked wire 1 is used, the tightened state may be loosened, and the stacked state of the veil may be collapsed, resulting in trouble in handling. In addition, the wire 1 may be cut from the kink portion, and the veil may collapse.

Therefore, the present invention provides a wire drawing device for supplying a tightening wire which can be smoothly unwound without applying a load to the wire when it is unwound and which prevents kinking. Is intended.
