Setup procedure and adjustment of the corn head

8.4.1 Adjustment of the snapping rolls
Three important settings must be observed when
installing or adjusting the snapping rolls:
8.4.2 Distance between the snapping roll shafts
Adjust the shafts parallel to each other by setting
62mm between the two bearing housings as shown
in the illustration. This distance can be increased or
decreased by using a washer spacer, as required.
8.4.3 Setting labyrinth seal
Two sealed double ball bearings are used to support the spiral
end of the snapping roll, and a labyrinth seal protect them. This
seal operates only if the distance between the stationary bear-
ing block and the rotating snapping roll is not larger than 0,5 or
1mm.
8.4.4 Alignment
The snapping rolls flatness comes from the snappingunit gearbox assembly, but the
parallelism to the axis must be checked. The axis of rotation of the snapping roll
must be parallel, both to each other and relative to the breaking line of the snapping
units frame.
