A method for forming element-free space sections in a slide fastener chain is provided that coupling elements can be efficiently removed by a small force without damaging fastener tapes The method for forming element-free space sections in the slide fastener chain comprises the steps of, cutting heads of interengaged discrete coupling elements of space-forming sections at one leg of forked legs of the individual coupling element, pushing up the heads of the coupling elements in the direction orthogonal to the fastener tape faces from the cutting side, and gripping the remaining cut legs by grippers to be drawn-out and removed in the direction orthogonal to the fastener tape faces.
