    • The tangling of hellically-coiled wire articles during bulk handling and shipment is prevented by providing integral modules or beads of fused metal at each end of the articles which enclose the severed ends of the wire. In the case of tungsten wire coils that are designed for use in electric lamps and similar devices and are wound on iron mandrels, the fused beads are composed of tungsten-iron alloy and formed in situ during coil manufacture by melting the ends of the mandrel with a concentrated heat source such as a focused laser beam. The tungsten-iron alloy beads remain on the end turns of the coil during the subsequent mandrel-dissolving operation, are ductile and are formed without embrittling the tungsten wire. Various methods and an apparatus for manufacturing such beadedend coils on a mass production basis using a CO2 laser are disclosed. Since the beads can readily be made larger than the diameter of the coil and be spaced a predetermined distance apart, they provide built-in guides or ''''reference points'''' for mounting incandescent lamp type filament coils on their lead wires and thus accurately controlling the lighted-length of the mounted coils.
    • 在批量处理和装运期间,通过在包裹线的切断端的物品的每一端提供整体模块或金属熔合金属珠来防止整体处理和运输中的线圈缠绕线制品。 在设计用于电灯和类似装置并缠绕在铁芯上的钨丝线圈的情况下,熔融珠由钨 - 铁合金组成,并且在线圈制造期间通过将芯棒的端部熔化 聚焦热源如聚焦激光束。 在随后的芯棒溶解操作期间,钨 - 铁合金珠保持在线圈的端匝上,是延展性的并且不会使钨丝脆化而形成。
