    摘要： A three-dimensionally curved configuration is imparted to a straight elongate element by removably retaining one end of the element with its axis coincident with a reference axis, partially pre-bending the element away from the reference axis into conformity with a two-dimensional first guide path, and thereafter bending the element into conformity with a three-dimensional helical second guide path.

    摘要： A forming disc exchanging method and apparatus for use in a forming apparatus for performing bending operations in multiple directions by timing and sequentially operating a plurality of bending slides. The forming apparatus includes a forming disc which includes a plurality of bending slides, a gear mechanism for actuating the bending slides, a product discharging device and a mold. A main forming machine has the forming disc removably attached thereto and includes a guide structure for allowing the disc to slide thereon. Further included is a truck which includes a drive device having the forming disc removably attached thereto for turning the gears, guides for allowing the disc to slide thereon, and a transfer device for sliding and transferring the forming disc.
