Abstract
Method for producing a decorated adjuster for a necklace or choker in which a tube of elastic is inserted into a metal pipe to thereby form a raw material. The raw material is moved along a longitudinal axis while being rotated and pressed between a pair of molds having adjoining concavities formed between ends of the mold and in opposed relation to concavities in the other mold. The concavities have a shape gradually approaching a hemispherical form in a direction from an entry end to an exit end whereby the last concavity has a hemispherical form such that the raw material is progressively formed into a shell element. The shell elements have an inner surface coated with the elastic material and are formed upon the continual movement of the raw material through the molds. The shell elements are separated from one another and a pair of opposed through apertures are formed to thereby form the decorated adjuster.
