Patent number: 9808056Abstract: A method of making a self-stopping bead for jewelry. The method comprises the steps of: inserting a resilient tube with an axial passage lengthwise into a relatively rigid tube having a longitudinal axis; deforming the rigid tube inward toward said axis at at least first and second spaced-apart locations along said axis until the rigid tube is necked down at said locations enough to pinch the resilient tube at a depression; and severing the rigid tube and the resilient tube at said depressions thereby forming a self-stopping bead with opposing holes wherein during the step of deforming, the rigid tube and the resilient tube are pinched off so that each hole in the bead receives therein an end of the resilient tube so that the resilient inner tube has a length substantially the same as an axial length of the self-stopping bead between the opposed bead holes.Type: GrantFiled: March 1, 2016Date of Patent: November 7, 2017Assignee: National Chain CompanyInventor: Steven A. Cipolla
