Document Type and Number:
Japanese Patent JP3329890
Kind Code:
B2
Abstract:
A tubular printing blanket (20) has a metal sleeve (42) which is receivable over a blanket cylinder (14) in an offset printing unit (10). The sleeve (42) is expandable diametrically under the influence of pneumatic pressure directed against the inner surface (46) of the sleeve (42), and is movable telescopically over the blanket cylinder (14) when in its expanded condition. The tubular printing blanket (20) has a damping ring (120) for attenuating noise upon expansion of the sleeve (42) under the influence of the pressurized flow of air. The damping ring (120) damps vibrations of the sleeve (42) which are caused by the pressurized flow of air, and which cause noise.
