Abstract: A method of constructing an index clip, embodying a wire spring clip, from a single, rectangular pliable member. The member is first divided longitudinally into four parallel sections. The member is then completely bent and folded along the boundary line between the first and second sections resulting in a first fold. A plurality of spring clips are installed in a spaced-apart relationship on the edge of the first fold. Sections three and four are then covered with a suitable adhesive and the member is completely bent along the boundary line between the second and third sections, near the ends of the springs, resulting in a second fold. The member is then again bent on the line between the third and fourth sections, resulting in a third fold. The folded structure is then pressed tightly for adhesion of the folds to each other and to the springs. Thereafter the folded structure is cut between the springs to produce individual index clips.
