  • Patent number: 5352507
    Abstract: A novel multilayered sleeve-like printing blanket is mountable on gapless cylinders or tubular blanket carriers, thereby minimizing vibration when operated at high rotational speeds. An exemplary printing blanket comprises a seamless outer printing surface layer; at least one reinforced elastomer layer, the elastomer layer being reinforced by fibers substantially parallel with the inward and outward sides of the cylindrical tube defined by the reinforced elastomer layer; and a resiliently compressible layer. The oriented fibers reinforce the elastomer layer such that the modulus of elasticity in the circumferential direction of rotation is increased. Exemplary methods for forming one or more of the layers are also disclosed herein.
