In general, the large diameter wire (W) has a diameter of φ14 ~ φ42mm, which is, as shown in Figure 1, after heating in the heating furnace 200 as a billet (B) as a material, several rolling mills 210 Roll through), through a plurality of guides 220 and finally wound in a coiled shape on the reel drum 230 in a round circle.

Among the large diameter wire coils, the large diameter wire coils (W) having a diameter of φ38 to φ42 mm have a large diameter, and thus are difficult to be bent in a circular shape, and thus a pre-bending machine cassette (Pre-bending Machine Cassette) ( 240) is installed and wound up.

As shown in FIG. 2, the pre-bending cassette 240 includes a motor 242, a speed reducer 244, a cassette member 246, and the like. Since the pre-bending cassette 240 also has a hydraulic cylinder 252 and the base plate 254 because it must be inclined and passed in order to be wound in the cylindrical reel drum 230 on the lower side while passing through It should be installed inclined through.

As shown in FIG. 3, the pre-bending cassette 240 has three driving rollers 260 installed in three zigzags, driven by a universal shaft 262, and two driven rollers 264 are wire rods. It rotates freely along the advancing direction of (W).
