  • Bladder with a constant contact region for cleaning a blanket cylinder
    Publication number: 20030209159
    Abstract: A bladder for bringing and engaging a cleaning cloth into contact with a blanket cylinder. The bladder has a molded (extruded or machined) shape optimized to, when inflated, provide a contact surface elevated above the remainder of the bladder. When the bladder is not inflated, the central portion is elevated above the remainder. In addition, the device has improved contact characteristics, providing significant improvement in the consistency of contact surface with less sensitivity to pressure fluctuations between the cylinder and the bladder over prior art.
