Abstract: A method of forming a decorative chain includes joining a first and second material in a layered relationship, each material having a different appearance, and forming such joined material into a spiral. A core is introduced into the spiral and then the core plus spiral are shaped into a desired configuration. Thereafter a portion of the first material along the outer surface is removed to reveal or expose a portion of the sub-layer of second material along the outer surface.

Abstract: A jewelry link made from square crossectional metal wire has a C-shape when the link is bent within a specially configured clamp over a mandrel, wherein the formed C-shaped links are diamond shaped in cross section. The links further have an outer circumference at their widest point formed by one of the four corner seams of a hollow or solid square wire, which is rotated 45 degrees onto one of its straight longitudinally extending edges before being bent around a mandrel. In that manner, the link is considerably wider than a link formed from square wire which is wrapped upon one of its surfaces over a mandrel.

Abstract: A straight wire length is bent against a mandrel into an obtuse V-shape and then into a C-shape at a first station, and against another mandrel into an oval shape at a second station. When making the V-shape bend the leading edge of the wire length is thereby contained against perpendicular movement. The wire length is then bent into a C-shape and when it is moved from the first station to the second station the stop is pivoted against the force of the spring by a bar transforming the V-shape to the C-shape. When the emerging C-shaped link clears the support surface of the stop element, the spring returns the stop element to its initial position in the first bending station, against a stop. The surface of the stop element contacting the stop may serve as an electrical contact for process control. Also, in the first station the vertical space between the straight wire length and the leading edge of the mandrel is greater than the diameter of the wire, thus clearing the path of the feed of the straight wire length into the first station for high productivity at least during the transport of the C-shaped wire piece from the first station to the second station.

Abstract translation: 将直线长度相对于心轴弯曲成钝的V形，然后在第一站处弯曲成C形，并且在第二站处将另一个心轴折叠成椭圆形。 当V形弯曲时，由此防止电线长度的前缘反对垂直运动。 然后将线长度弯曲成C形，并且当其从第一工位移动到第二工位时，止动件通过将V形转换成C形的杆抵抗弹簧的力而枢转。 当出现的C形连杆清除止动元件的支撑表面时，弹簧将止动元件返回到第一弯曲站中的初始位置，停止。 接触止动件的止动元件的表面可以用作过程控制的电接点。 此外，在第一站中，直线长度与心轴的前缘之间的垂直间距大于线的直径，从而将直线长度进给到第一站的路径以高生产率清除 至少在将C形线材从第一站运送到第二站期间。

Abstract: AN APPARATUS FOR PRODUCING ONE-PIECE LINKS IN ONLY TWO STATIONS. THE FIRST OF THESE STATIONS CONTAINS A MECHANISM FOR SEVERING A PIN OF A PREDETERMINED LENGTH FROM A ROD OR WIRE BY MEANS OF TWO NOTCHING BLADES WHICH RECIPROCATE IN OPPOSITE DIRECTIONS TO EACH OTHER WITHIN THE SAME PLANE EXTENDING TRANSVERSE TO THE AXIS OF THE ROD. THE FIRST STATION FURTHER CONTAINS A PRESS CLOSELY ADJACENT TO AND PRECEDING THE SEVERING MECHANISM FOR CLAMPING THE ROD IN A FIXED POSITION DURING THE SEVERING OPERATION AND FOR BENDING AT THE SAME TIME THE CENTRAL PART OF THE PIN BEFORE BEING SEVERED TO PROVIDE THE LINK WHEN SUBSEQUENTLY BENT WITH A CURVED BACK. THE SECOND STATION CONTAINS A SINGLE BENDING UNIT IN WHICH THE PREVIOUSLY SEVERED PIN IS BENT WITH A CURVED BACK. THE ACTION TO ITS FINAL SHAPE BY TWO BENDING ROLLERS WHICH ROLL THE PIN ABOUT A BENDING MANDREL AND ARE CONNECTED TO GUIDE ROLLERS WHICH ROLL ALONG GUIDEWAYS SO THAT THE BENDING ROLLERS THEMSELVES ARE INDIRECTLY GUIDED AND ONLY HAVE TO ENGAGE WITH THE PIN DURING THE BENDING OPERATION. AFTER A PIN HAS BEEN SEVERED IN THE FIRST STATION, IT IS PASSED BY CONVEYING TONGS FROM THIS STATION TO THE BENDING UNIT AND INTO THE PROPER POSITION THEREIN FOR THE BENDING OPERATION.

Abstract: A method of forming a decorative chain includes joining a first and second material in a layered relationship, each material having a different appearance, and forming such joined material into a thread comprising a core of a third material. In one embodiment, the thread is introduced onto a support to form a spiral, and the spiral is separated into chain elements or links that are intertwined to form jewelry chains. Thereafter a portion of the first material along the outer surface of the chain is removed to reveal or expose a portion of the sub-layer of second material along the outer surface. In one embodiment, the thread core is maintained for solid link chain. In another embodiment, the thread core is removed to form hollow link chain. In either case, the outer surface of the chain is provided with contrasting appearances from the first and second materials.
