An improved link-making machine is described which comprises a frame and a mandrel mounted on the frame outwardly directed from the frame and arranged to receive the wire thereon. Means to form the wire are located adjacent the wire and disposed to receive the wire and to direct the wire around the mandrel to form a plurality of loops thereon, the outermost of which is positioned toward one end of the mandrel and characterized by an open eccentric end portion. Means to provide wire are adapted to the frame and positioned to direct the wire upon the means to form the wire and includes a power source and means to move the wire connected to the power source and activated by the power source to move the wire from a first position to a second position closer to the means to form, the distance between the two positions substantially corresponding to that length of wire required for one link. Means to close the outermost loop to form the link are located to move between a position distant from the outermost eccentric loop to a position in contact with the outermost eccentric loop to close the outermost eccentric loop. Finally a cutter adapted to the frame and joined to the means to close the outermost eccentric loop before the loop is cut comprises a power source and a blade member connected to the power source which is activated to move between an open position distant the mandrel to a closed position close to the mandrel to cut the link from the wire.
