The machine is widely used for binding notebook, workbook, calendar and so on. The wire is unwound from a spool, straightened and smoothed by the special rectifying tools of the machine and then is guided via guide-rollers to the mandrel which forms the spiral and regulates the spiral diameter. The pre-punched product is placed onto the book supports. By starting the machine the spiral is introduced into the perforation. The needed spiral length can be adjusted at the electronic wire length control. The machine stops automatically when the wire reaches the required length and then the spiral is cut off and both spiral ends are bend inwards. The machine is ready for the next cycle.
