摘要： 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.

摘要： An exemplary anisotropic printing element comprises an outer printing surface layer and, located radially beneath the outer layer, a spirally-integrated reinforced compressible tubular structure comprising a reinforcing sheet having synthetic fibers, the sheet being spirally wrapped at least two complete turns circumferentially around the longitudinal axis of the tubular structure, thereby defining an inner tubular surface on a radially inward wrapped sheet portion and an outer tubular surface on a radially outward wrapped sheet portion, the tubular structure further comprising an elastomer having voids, the elastomer being disposed between the inner and outer tubular surfaces defined by the wrapped sheet portions, the void-containing elastomer thereby providing radial compressibility to and being spirally-integrated within the tubular structure. Examplary methods for fabricating the printing elements of the invention are also disclosed.
