Every facility has belts that mistrack from time to time, and most react by immediately adjusting the head or tail pulley. A better action is to identify the reason why the belt is mistracking and correct that issue. If adjustments need to be made, they should be made to low-tension rollers. The amount of friction between the low-tension rollers is identified by the drive pulley and the belt. The head pulley and tail pulley should be aligned and square. Once a belt mistracks, structure and belt damage can occur along with material spillage
Tracking a belt should be a methodical process. If the belt is still mistracking after initial attempts to resolve the problem, one needs to determine and recognize all reasons causing the belt to mistrack and correct them. Identify the low-tension rollers which are found after the drive pulley and adjust the roller prior to where the belt starts to wander. Tracking devices can aid in belt alignment and can sometimes prevent the need for the rather cumbersome “trial and error” process of identifying the root causes.
