ABSTRACT:
A compressible roller especially useful in high speed printing systems consists of a rigid core and a compressible cover. The cover consists of a first relatively thick layer of compressible foam containing entrapped gas which is bonded to the core; an elastomeric seal, which prevents the entrapped gas from leaving the foam, bonded to the foam; and an outer print layer of a compatible elastomer bonded to the seal.
