    • 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.
    • 制作珠宝自制珠的方法。 该方法包括以下步骤:将具有轴向通道的弹性管纵向插入具有纵向轴线的相对刚性的管中; 沿着所述轴线至少在第一和第二间隔开的位置使所述刚性管向内朝向所述轴线变形,直到刚性管在所述位置处颈缩,足以将弹性管夹在凹陷处; 并且在所述凹部处切断刚性管和弹性管,从而形成具有相对孔的自阻止珠,其中在变形步骤期间,刚性管和弹性管被夹紧,使得胎圈中的每个孔容纳其中的端部 使得弹性内管具有与相对的胎圈孔之间的自停胎圈的轴向长度基本相同的长度。
