[0028]

As described above, according to the bundling method and the bundling apparatus of the present invention, the non-wound portions of the multifilament wound around the material to be bound are bundled with each other, and the base of the non-wound portion has compressibility. Since the entanglement process is performed by ejecting the fluid and the binding is performed, there is an effect that a hard and large nodule does not occur and is not noticeable.

Further, if the entanglement process is performed at both the base end portion of the non-winding portion and the vicinity of the base end portion and cut between them, the object to be tied is bound and the multifilament of the non-winding portion is cut. Are connected to each other. For this reason, the continuous supply of the multifilament becomes possible, and it is possible to continuously shift to the next bundling step, so that the bundling can be automated efficiently.
