Claims: What is claimed is:

1. A method for making ribbons which can be curled up in various aesthetically pleasing configurations, the method comprising the steps of:

unwinding from at least one ribbon supply roll at least one ribbon;

feeding said ribbon in a given feed direction in a stepwise fashion by predetermined steps through a set of guide elements;

simultaneously unwinding a tape from a tape supply roll;

feeding said tape in said feed direction in a stepwise fashion by the same predetermined steps as for the ribbon;

passing said tape in superimposed relation to said ribbon between said set of guide elements so that the tape lies longitudinally of the ribbon and at the central area thereof;

feeding said ribbon along with the tape to a shearing area;

laterally shearing a portion of both lateral sides of the ribbon to define two opposed roundish side cuts;

feed said sheared ribbon along with said superimposed tape to a stitching area;

closing a metal ring around said ribbon and tape at the center of each sheared area, in timing relationship with the stepping of said ribbon, so that upon being closed about said ribbon said ring holds the ribbon and tape together in a loose sliding relationship; and

transferring said ribbon, tape, and rings so assembled to a final take-up roll.

2. The method as set forth in claim 1, wherein said steps of shearing said ribbon and closing said ring are performed in a manner to vary the spacing between successive sheared areas and rings.
