Belts that run on bare lineshafts (line-shafts) usually “walk and wander”, i.e., screw down the shaft and snap back repeatedly. This causes high frequency vibrations that stretch and abrade belts, greatly reducing belt life. This is one reason why lineshaft spools are used.
Spool flanges prevent walking and thereby increase belt life. Only one flange per belt is needed because belts walk in only one direction – the direction of conveying motion, i.e. downstream.
