A drum dryer seal is built up of six layers of high temperature ceramic cloth that form a blanket. The top layer is aluminized, high temperature barrier yarn, to prevent air from passing through the seal. The blanket is clamped to a bracket on the non-rotating portion of the dryer by a clamp consisting of a clamping strip and a plurality of clamping bolts. The clamping bolts may also hold a plurality of C-shaped spring retention brackets, the upper leg of each holds a resilient spring. The springs overlie the sealing ring. A plunger is mounted on the spring which is positioned over a sealing ring. The plungers bias the blanket against the sealing ring. An alternative embodiment employs spring rods incorporated in the blanket which extend between the bracket and the sealing ring.
