The windingspeed controller 200 is mounted on thesecond platform 923 in proximity to thesecond coiler 922 in this embodiment. Thesecond platform 923 supports the second runout table 924 and thesecond coiler 922, and is movable relative to theupcast casting apparatus 6 between third and fourth positions. When thesecond platform 923 is in the third position, as shown inFIG. 8 , thesecond coiler 922 is aligned with thesecond drawing unit 8 so as to wind themetal rod 500′ drawn by thesecond drawing unit 8 into a coil. When thesecond platform 923 is in the fourth position, as shown inFIG. 9 , the second runout table 924 is aligned with thesecond drawing unit 8 so as to collect themetal rod 500′ drawn by thesecond drawing unit 8 and to cut thecopper rod 500′ to a preset length by using acutter 400. With reference toFIG. 7 , the drawnmetal rod 500′ is wound into a coil by thesecond coiler 922 through cooperation of theguide roller 300 and the windingspeed controller 200. Alternatively, the drawnmetal rod 500′ may be collected on the second runout table 924, as shown inFIG. 9 , and may be cut to a preset length using the cutter 400 (shown in phantom lines inFIG. 9 ). - The
second collecting unit 92, in this embodiment, includes only onesecond coiler 922. However, when thesecond drawing unit 8 draws a plurality ofmetal rods 500′ from theupcast casting apparatus 6, thesecond collecting unit 92 may be provided with a plurality of thesecond coilers 922 to wind themetal rods 500′ into coils, respectively. Since the upcast andhorizontal casting apparatuses units upcast casting apparatus 6 is disposed higher than thehorizontal casting apparatus 5, and since thesecond collecting unit 92 is also disposed at a level substantially as high as theupcast casting apparatus 6, the winding operation of thesecond collecting unit 92 can be carried out effectively. - Referring to
FIG. 10 , equipment for a continuous casting operation according to the third preferred embodiment of the present invention is shown to be similar to the second preferred embodiment. However, in this embodiment, thehorizontal casting apparatus 5 cooperates with thefirst collecting unit 7 to produce fourelongated metal rods 500. Similarly, theupcast casting apparatus 6 can cooperate with thesecond collecting unit 8 to produce simultaneously fourelongated metal rods 500′ (seeFIG. 7 ). Hence, the production yield is further increased. Since the upcast andhorizontal casting apparatuses elongated metal rods 500′, 500, each of the first andsecond collecting units 91, 92 (seeFIG. 7 ) is provided with fourcoilers 912, 922 (seeFIG. 7 ) to cooperate with thecorresponding casting apparatus metal rods 500′, 500 into coils, respectively. - Moreover, in this embodiment, the
horizontal casting apparatus 5 includes four first dies 51 (seeFIG. 7 ) and four first coolers 52 (seeFIG. 7 ). Thefirst collecting unit 7 is modified so as to accommodate drawing of the fourelongated metal rods 500. Similarly, thesecond collecting unit 8 is also modified so as to accommodate drawing of the fourelongated metal rods 500′. Since modification of each of the first andsecond collecting units - It should be noted that since the first and
second collecting units 91, 92 (seeFIG. 7 ) in this embodiment are operated in a manner similar to the manner in which they are operated in the second preferred embodiment, only thefirst collecting unit 91 is illustrated inFIG. 10 . InFIG. 10 , thefirst platform 913 is disposed in the second position. The aforementioned end product, i.e., theelongated metal rods second drawing units units - While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
