General description of the conveying system
All rolls have to be adjusted possibly parallel and right-angled to the belt axis.
The correction of the belt run is adjusted by the drive- and deflection rollers. The
adjustment should be arranged at the rolls, at which the belt starts up. In contrast to the
belt drive, where as a consequence of round disks and really high circumferential velocity
the belt moves to the highest location, for belt straps. The following is valid: the belt
moves to the side of the minor voltage.
Normally, a belt has to be retensioned during running-in time several times and the belt
run has to be corrected. Then a belt strap runs efficiently under standard operating
conditions. Deposits at the rollers influence the belt leveling. Particularly at the bottom
side of the strap, dirt, wastage and other small parts may reach the roller and may cause
deposits. This influences the lateral belt leveling. Therefore a regular cleaning of the
system, especially of the belt run bed, is necessary. Therefore the belt is slightly lifted and
the track bed is cleaned. If required, the belt tension has to be decreased to lift the belt.

Danger of being pulled in by rotating elements.
HEALTH HAZARD!
The check of the web run has to be arranged at running system
