ABSTRACT:
A seal device between the infeed end of a rotating cylinder and the discharge end of a stationary chute wherein the discharge end of the stationary chute is received within an opening in the infeed end of the rotating cylinder. The seal device includes a flexible material of ring-shaped configuration wherein the inner diameter of the ring is substantially the same as the outer periphery of the discharge end of the stationary chute the flexible material being fixedly attached and circumscribing the discharge end of the cylinder. A compression device is attached to the discharge end of the stationary chute, the compression device including an outwardly extending end which is in compressing relationship with the outer periphery of the flexible material forcing the flexible material against a transversely extending inner wall of the infeed end of the rotating cylinder.
