To provide a metal wire-ligating machine that can prevent the wire- supporting wire-cutting part from abrading and avoid the wire from forming peeling powder particles, when the metal wire cut in a prescribed length is formed in a U-shape before wire ligation.

This wire-ligating machine is for bundling the tubes filled its hollow parts with a filling substance at a prescribed interval in the longitudinal direction and ligating the bundled parts with metal wires, and is composed of a pair of bundling parts and the cutting part for cutting the metal wires in a prescribed length, the pressing part for pressing the metal wire cut toward the space formed by the cutting part to a U-shaped form and a couple of ligating part in the form of a mold for collapsing the U-shaped wire to ligate the bundled parts. In this wire-ligating machine, the cutting part 1 is equipped with a movable guide 8 of which the point contacting with the metal wire deformed to the position supporting the metal wire moves together with the wire during the molding.
