Spiral wre binding

- Nov 16, 2017-

The spiral wire binding is made up of several parallel metal wires, which are automatically locked after drilling through the edge of the printing edge, and then the printed matter is fixed together. With PVC cover binding, the plastic studs connected to the PVC cover pass through the drill holes at the edge of the print and are joined by another PVC cover underneath.
