    • The coil spring manufacturing device (1A) includes a first continuous material mounting portion (4), a second continuous material mounting portion (5), a straightener (7), a cutter (8) which cuts a material (2), a short material mounting portion (9) on which a short material (2') obtained by the cutting is mounted, and a coiling machine (10). The material (2) reeled out from a first continuous material (2A) or a second continuous material (2B) is cut by the cutter (8). The coil spring manufacturing device (1A) can switch a process among a first continuous material coiling process of manufacturing a coil spring by using the material (2) reeled out from the first continuous material (2A), a second continuous material coiling process of manufacturing a coil spring by using the material (2) reeled out from the second continuous material (2B), and a short material coiling process of manufacturing a coil spring by using the short material (2').
    • 螺旋弹簧制造装置(1A)包括第一连续材料安装部分(4),第二连续材料安装部分(5),矫直机(7),切割材料(2)的切割器(8) 其上安装有通过切割获得的短材料(2')的材料安装部分(9)以及卷绕机(10)。 从第一连续材料(2A)或第二连续材料(2B)中拉出的材料(2)被切割器(8)切割。 螺旋弹簧制造装置(1A)能够通过使用从第一连续材料(2A)放出的材料(2),第二连续材料卷绕工序来制造螺旋弹簧的第一连续材料卷绕工序 通过使用从第二连续材料(2B)放出的材料(2)的螺旋弹簧以及通过使用短材料(2')制造螺旋弹簧的短材料卷绕过程。
