ABSTRACT:
A lightweight pliable heat and noise insulator blanket is mounted to the exterior surface of the axial end wall of a temperature controlled cylinder. The insulator blanket comprises multiple layers of heat and noise insulation material, and the blanket defines a central opening and a slot extending from the central opening through the outer peripheral edge portion so that the blanket can be positioned about the axle of the rotary cylinder. The insulator blanket includes an annular protrusion just inwardly of its outer periphery for placement against the exterior surface of the axial end wall of the rotary cylinder to form a seal between the insulator blanket and the rotary cylinder. The outer peripheral portion of the insulator blanket extends about the connector screws of the rotary cylinder while the annular seal of the insulator blanket is urged by centrifugal force toward a sealed relationship between the insulator blanket and the axial end wall of the rotary cylinder.
