| Snub Idlers: |
| |
| Adjustable snub rollers in the section running
towards the tail roller are particularly well suited for tracking
and guiding a conveyor belt. |
|
| To adjust the snub roller, shift it in the direction
A-B. |
| |
| To achieve a good tracking effect, the arc of
contact at the snub roller has to be minimum 30 degrees. |
| |
| The tracking effect can be further enhanced by
a coated snub roller (friction cover made of rubber or plastic. |
