Using a servo drive system provides an extremely high cyclic rates as there is no longer any target to obstruct the core.
An encoder is able to measure the speed of the inside ply coming into the winder, this then synchronises the cutting unit to the core speed.
This Multi Flying Knife Machine works on the same principal as the single knife in-line cutters except that due to the fact that we are using several knives to cut with, the tube is carried by servo driven support rollers. This is in order to guarantee that each cut is complete without the various pieces “tailing” together.
Each of the multi knife units is then individually servo operated in order to allow fine adjustments via the touch screen keypad. This is further aided due to the long cutting stroke available.
