High quality multi knife paper core producing units

Using a servo drive system gives very high cyclic rates as there is no longer any target to obstruct the core. An encoder measures the speed of the inside ply coming into the winder, this then synchronises the cutting unit to the core speed.This works on the same principal as the single knife in-line cutters except that because we are using several knives to cut with, the tube is carried by servo driven support rollers. This is to ensure that each cut is complete without the various pieces "tailing" together.Each of the multi knife units is then individually servo operated to enable fine adjustments via the touch screen keypad. This is further aided because of the long cutting stroke available.
