By G.A. Kribitz –The direction of a conveyor belt is changed, at pulleys, according to the wrap angle between the pulley and the belt. Compared with idler rollers which just support a conveyor belt, pulleys, due to the wrapping belt, provide different opportunities concerning belt tracking. Due to relatively high belt tensions and wrap angles combined with the according friction factors, pulleys mainly provide static friction to the conveyor belt at the ongoing side . There are different hypotheses available in literature for the explanation of belt tracking and belt misalignment effects concerning pulleys, but apparently none seems to be accepted to be generally valid.
