20’ eliminates this geometrical consideration and tells us whether we have
a cambered belt.

4. Camber is measured by drawing a taut line along one edge of the belt

(inward camber edge) and measuring maximum deviation from that taut line
to the belt at the center point of that line.

5. Compute

percent

camber:

• % camber = [max. deviation (inches/cm)] / [length of taut line (inches)] x

100

Camber can be instilled into a belt during the slitting operation if one of the slitting
knives is dull. A dull slitting knife will tear the fill yarns (crosswise yarns) rather
than cut them. While the belt is in roll form, the side of the belt which has gone
through the dull knife will exhibit a "fuzzy" appearance due to the torn fill yarn.
Usually, this type of camber will be less than 1/2 of 1% and can be easily pulled
out when the belt is properly tensioned and tracked.

Camber is typically instilled into a belt during improper storage.

Currently, there is no accepted camber standard in the US market. For a
maximum acceptable camber relative to a given conveyor belt construction,
please contact your belt manufacturer.

7.2.6. S

)

The horizontal fill yarns in the belt carcass will usually lie perpendicular to the belt
centerline. Any deviation from the perpendicular by the fill yarn is called "skew"
or "bow."

A skewed pick in a plain or square weave is cause for concern since it is
generally indicative of unbalanced warp tensions and will usually go hand-in-
hand with a significant camber.

In a straight warp or solid woven carcass, skew is of little significance. It is
usually a cosmetic defect and is not indicative of a cambered belt.
