  • Patent number: 7069854
    Abstract: An improved method and system for cleaning a cylinder of a printing press. One method involves soaking a strip of cleaning fabric on a press with a low volatility organic compound solvent. Excess solvent, if any, is removed to place the strip of cleaning fabric in functional equilibrium with the solvent. The cleaning fabric is then used to clean a cylinder. Alternatively, the strip of cleaning fabric is soaked on site by contacting the strip of cleaning fabric with the solvent and wrapping the strip of cleaning fabric into a cleaning fabric supply roll. The cleaning fabric is then brought in engagement with a printing press having a cylinder to be cleaned without disposing a sleeve around the fabric roll and without substantially disturbing the distribution of the solvent in the fabric roll and detrimentally affecting the cleaning ability of the fabric.

  • Patent number: 6035483
    Abstract: A cleaning system employing a highly viscous cleaning agent. A highly viscous cleaning agent is placed on a strip of cleaning fabric whereby the strip of cleaning fabric is made functional for cleaning cylinders of printing presses. The strip of cleaning fabric is wrapped around the center piece. The strip of cleaning fabric may then be brought into contact with a cylinder to be cleaned in order to clean the cylinder. The highly viscous cleaning agent may be made by mixing a viscosity adding agent with a low volatility, organic compound solvent. Additionally, water or another additive may be mixed in for improved cleaning properties. The method of making the same is also discussed.

  • Patent number: 5974976
    Abstract: A cleaning system for a printing press using pre-soaked, reduced volume of air in cleaning fabric and a method for making the system are disclosed. The system includes a cleaning fabric treated to reduce the amount of air volume the cleaning fabric contains. The cleaning fabric is saturated to functional equilibrium with a low volatility organic compound solvent. The cleaning fabric is wrapped around an elongated core to form a fabric roll. The saturated, wrapped fabric roll may be used to clean a cylinder of a printing press. The saturated, wrapped fabric roll may be inserted in a sealable sleeve, the sealable sleeve being in contact with the fabric roll and then sealed, thus permitting transporting and storage of the system until use without detrimentally affecting the cleaning ability of the fabric.

  • Patent number: 5819660
    Abstract: An improved apparatus and method for cleaning one or more of the rollers used in printing presses. Typically, the printing press features manual or automated devices for supplying cleaning solvent to the press during a washing operation. A blade assembly is pivotally disposed for engagement with the press roller. The blade assembly features a blade unit for scraping solid and liquid debris from the roller, and a receptacle trough for collecting used solvent as well as solid and liquid debris. In the improvement, a sheathing system is provided to supply protective sheath material to cover the blade assembly to keep the blade assembly clean during the washing operation. The sheath material preferably has a low coefficient of friction to prevent wearing of the components and is relatively thin to maintain the blade geometry for effective cleaning of the roller.

  • Patent number: 5368157
    Abstract: There is disclosed a pre-packaged, pre-soaked cleaning system for use to clean the cylinders of printing machines. The system includes a pre-soaked fabric roll saturated to equilibrium with low volatility organic compound solvent which is wrapped around a cylindrical core having open ends to form a roll. The saturated, wrapped fabric roll is inserted in a heat-sealable or heat-shrinkable and heat-sealable plastic sleeve, the sleeve being to intimate contact with the fabric roll after being subjected in heat-sealing or heat-shrinking and heat-sealing, thus permitting transporting and storage of the system until use without detrimentally affecting the cleaning ability of the fabric roll.The system may also include a slotted canister in which the saturated wrapped roll is inserted before it is placed into the plastic sleeve and heat-sealed or heat-shrunken and heat-sealed thereon or end caps inserted in the open ends of the core.A method for making the system is also disclosed.
