Endless rubber track laying machines are provided with a pair of track laying assemblies positioned on opposite sides of the work machine. Each track laying assembly includes an endless rubber belt entrained around a drive wheel, an idler wheel, and a plurality of supporting mid-rollers. The present supporting mid-roller includes a heat shield that is positioned between individual roller segments and guide blocks positioned on the inner surface of the endless rubber belt. With the heat shield in this position, heat generated from the guide blocks contacting the individual roller segments is dissipated, thereby increasing the life of the individual mid-roller components.
