五光発條 × Sountrive

goko bane

The coiling machine moves with a peerless precision. It is a scene of rows of robotic arms, motors and pumps regulating their movement, intricate gears, and a wide array of springs, pumped out endlessly. Sountrive captures organically the movements and sounds of this process of incredible efficiency. It is almost as if the machinery itself is creating its own polyphonic groove.

  • The manufacture of springs can be roughly divided into two methods: “rolling” and “bending”. In the case of this spring, it is first rolled, then bent, then bent back, and rolled a second time.

  • The metal wires in the center of the screen are sent in from the back and gradually altered by the tools situated around the rods.

  • The wire that is used to manufacture the springs. The type of metal wire that the springs are made from depends on the type spring being manufactured.

  • The devices inside the manufacturing machines are all fine tuned by engineers so that the wire is bent in exactly the right way.
