A pulley lagging that is easy to replace, like Slide-Lag, is welded onto the surface of the drive pulley, or rubber with a diamond profile is bonded to the surface using a vulcanisation process. The rubber version is also available in food-grade quality and comes in white or blue. If a rubber pulley lagging does not suffice, for instance at very high temperatures, we apply METALLAG steel segments with a ceramic or sintered nickel plating.
