WIRE MESH BELT ALIGNMENT
Wire mesh belts are designed and built to run true when all rollers and support beds
are level from left to right and at right angles to the centerline of the conveyor.
It is essential that all drive rollers and take up rollers are mutually parallel.
(see page 32) .
WIRE MESH BELT TRACKING
Tracking a wire mesh belt is accomplished by using the proper procedures. The most
important principle is that a wire mesh belt always tracks in a direction perpendicular
to the support rolls over which it passes. To track the belt in a particular direction,
it is only necessary to skew the support rollers in the desired direction. Do not track
the belt by moving the end rollers out of parallel. The following are the steps required
to track a wire mesh belt.
1. Make certain the Seed Conditioner unit has been carefully aligned following the
procedure described above and the diagrams on page 32.
2. Place at least one mark on the belt with paint or chalk to serve as a reference point
in tracking adjustments.
3. Run the belt for several complete revolutions. On each revolution, measure the
lateral position of the reference point on the inlet drive roller. This will indicate the
direction and extent of lateral movement.
4. If adjustment are required , adjust the support rollers. The support rollers should be
adjusted a measured distance in the direction of the discharge end and on the side
of the conveyor where belt side travel is noted. Or, adjust the rollers towards the
inlet end on the opposite side of the conveyor or both. It is important to keep in
mind
always
that slight adjustments on each roller are more effective than large
adjustments on one or two rollers.
5. Continue checking the lateral position of the reference point and making
adjustments until the belt tracks on the inlet drive roller consistently in the proper
position. At this point the belt is tracking in a repeating pattern.
6. Check the lateral position of the belt on the discharge roller. If it is satisfactory,
tracking is complete.
