Method for producing a decorated adjuster for a necklace or choker

A method for producing an decorated adjuster for a necklace or choker, comprising the steps of:

• a. producing a raw material comprising a precious metal pipe and a tube of elastic material arranged in said precious metal pipe;
• b. intermittently moving the raw material along a longitudinal axis;
• c. pressing the moving raw material between a pair of molds, each of the molds having a plurality of concavities for molding the raw material, the concavities having the same shape as a profile of a shell element in said decorated adjuster, the obtained shell elements each having an inner surface coated with said elastic material and being formed consecutively upon the continual movement of the raw material through the molds;
• and
• d. cutting off the consecutive shell element, said cut-off shell elements each having a pair of through apertures bored and arranged at a place in said shell element in face to face relation to one another to thereby form the decorated adjuster, the through apertures being slightly larger than the width in a front end of a decorated chain in which a U-shape is formed, when the decorated chain is inserted into the through aperture.

A method for producing a decorated adjuster for a necklace or choker, comprising the steps of:

• inserting a tube of elastic material into a metal pipe to thereby form a raw material;
• intermittently moving the raw material along a longitudinal axis while intermittently rotating the raw material;
• pressing the moving and rotating raw material between a pair of molds having a series of adjoining concavities formed between ends of the mold and which are in opposed relation to concavities in the other mold, the concavities having a shape gradually approaching a hemispherical form in a direction from an entry end to an exit end whereby a last one of the concavities in the molds has a hemispherical form such that the raw material is progressively formed into a shell element upon the progressive movement of the raw material, the shell elements obtained at the exit end of the molds each having an inner surface coated with the elastic material and being formed consecutively upon the continual movement of the raw material through the molds;
• separating the shell elements from one another;
• and
• forming a pair of opposed through apertures in the shell elements to thereby form a decorated adjuster.

• inserting a tube of elastic material into a metal pipe to thereby form a raw material;
• intermittently moving the raw material along a longitudinal axis;
• pressing the moving raw material between a pair of molds having a series of identical, adjoining concavities formed between ends of the mold and which are in opposed relation to concavities in the other mold, the concavities having the same shape as a profile of a shell element such that the shell elements obtained at an exit end of the molds each have an inner surface coated with the elastic material and being formed consecutively upon the continual movement of the raw material through the molds;
