Open the CIPO recordAbstract From the Canadian patent
Spaced elastomer ribs cooperating with the outer cylindrical surface of a flexible track belt within the confines of each track shoe site with a sufficient volume of elastomer in each rib will, when a track shoe is attached to the sites, be deformed to increase the stiffness of the belt in the flexing area between adjacent track shoes and improve the resistance to the ingress of dust and the like between the belt and the underside of each track shoe due to the resiliency of the elastomer in the ribs allowing, them to maintain continuous contact with the underside of the track shoe and the cylindrical belt.
