SMART FEED CONTROL FUNCTION DURING
CHIPPING
When Smart Feed control detects knife disc rotation
speed decreasing, it switches off the forward feed and
activates feed reverse, which separates the wood of cut-
ting knives. Forward feed continues automatically after
reversing.
Forward feed switching off point depends on power and
torque of the tractor or other power source. The more
powerful the power source is, the bigger dropping of the
knife disc rotating speed Smart Feed allows. This me-
ans less pauses during the chipping. There will be pauses
more often if a tractor or other power source has less
power.
Smart Feed control reverses automatically, if feeder
blocks up. During chipping, the upper feed roller pressu-
re is watched by pressure sensor (4). If the feed rol-
ler gets stuck, Smart Feed control automatically briefly
reverses the feed rollers. After reversing forward feed
continues automatically. In most of the cases reversing
releases any wood stuck in feeder. Reversing function re-
peats until stuck wood gets loose, or user switches the
forward feeding off. In some cases, wood might get stuck
into feeder so tight, that reversing function can’t loose
the wood automatically. Then you need to use hydraulic
crane to loose the wood.
When the blockage is removed, activate forward feed and
continue chipping.
