Abstract: A conveyor has a belt arranged to be urged around conveyor rollers, and a belt cover formed of an endless loop of fabric material and is in frictional communication over the belt. The belt cover is formed of two plies that are arranged to be adhered to one another in an edge region of the belt cover. The communication between the belt cover and the belt has a coefficient of friction of ˜0.50. A message is printed on the outer ply of the belt cover. In addition, an antimicrobial material is disposed on the belt cover, and is formed of silver nanoparticles embedded in a polyurethane film having a thickness of ˜0.5 mil.

Abstract: A conveyor has a belt arranged to be urged around conveyor rollers, and a belt cover formed of an endless loop of fabric material which is in frictional communication over the belt. The belt cover is formed of a polyester carcass that has a monofilament weft that is transverse to the direction of travel, and maintains alignment with the belt. The belt cover is installed to a tensile force of between 1 and 1.5 pounds/inch, corresponding to an overall elongation of approximately 0.1%, which allows frictional communication between cover and belt for load transmission without binding. The communication between the belt cover and the belt has a coefficient of friction of ˜0.50. A message is printed on the belt cover. In addition, an antimicrobial material is disposed on the belt cover, and is formed of silver nanoparticles embedded in a polyurethane film having a thickness of ˜0.5 mil.
