5.3.2 OptiCut 23
5.3.2.1 General
The cutting mechanism OptiCut 23 is fitted with 23
knives which give a theoretical cutting length of 45
mm.
Each knife is individually protected by a hydraulic
cylinder (1).
(A) If pressure is released from the system, the hydraulic
cylinders are drawn completely in by springs and the
knives are retracted inside the floor of the cutting
mechanism.
(B) Hydraulic pressure on the system moves the knives
to cutting position and causes the hydraulic pressure
accumulator (4) to be filled.
(C) If a stone (5) or a solid obstruction enters the feed
mechanism, the affected knife swings clear. The
hydraulic cylinder is drawn in permitting the retraction
of the knife into the floor of the cutting mechanism. Then
the hydraulic pressure accumulator (4) will run out the
cylinder again, so the knife moves back to the cutting
position.
Note
A possible dropwise leakage at the single
acting hydraulic cylinders (1) cannot be
excluded, but will not impair the function
of the system. The cylinders should
therefore be run out prior to storage.
