Clips adapted to be subsequently employed in tying the necks of bags and the like are formed in a continuous ribbon of metallic material and adapted to be wound on a reel for subsequent use as ties. A continuous ribbon of flat material is bent alternately in opposite directions at spaced points along its length to form a continuous length of generally sinusoidal-shaped similar connected elements so that substantially all of the deformation of the material takes place when the approaching end of the ribbon is free and thus not subject to being stretched or compressed except so far as these deformations take place during the bending process. The continuous length of generally sinusoidal-shaped similar connected elements resulting from the bending step is passed between complementarily formed die elements similar to the teeth of a pair of mating gears so as to deform the crest of the sinusoidal elements to generally trapezoidal shaped elements which, when separated, serve as ties for surrounding the neck of a bag or the like.
