ABSTRACT:
A metallic end bead is attached to the main wire of a musical instrument string by providing the bead in apertured form, roughening or otherwise irregularizing its hole surface and then plastically deforming it to press its hole surface irregularities into the surface of a wire inserted through the hole. The bead has tapered end portions to inhibit cracking during the deforming step. The process is one lending itself to economical mass production of beaded strings and the beads may be provided with either a matte or polished finish on their visible surfaces.
