Soak on site and soak on press cleaning system and method of using same
View Patent ↗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.
1. A method of presoaking cloth for cleaning a cylinder in a printing press, the method comprising:
contacting a cleaning fabric supply roll with a low volatility, compound solvent which does not evaporate readily at ambient temperature and pressure and soaking and saturating said cleaning fabric supply roll with said solvent, such that the contacting of the cleaning fabric supply roll with the solvent does not require the use of pumps, spray bars, manifold lines and valves;
removing excess solvent from the cleaning fabric supply roll in a controlled and regulated manner prior to cleaning the cylinder of the printing press, wherein the solvent removal occurs outside a container holding solvent; and
engaging said saturated cleaning fabric supply roll with a printing press having a cylinder to be cleaned without disposing of a sleeve about said fabric roll and without substantially disturbing the distribution of said solvent in said fabric roll and detrimentally affecting the cleaning ability of the fabric.
2. A method of presoak cloth for cleaning a cylinder in a printing press, the method comprising:
wrapping a cleaning fabric supply roll around a core, and subsequently contacting said cleaning fabric supply roll with a low volatility, compound solvent which doses not evaporate readily at ambient temperature and pressure and soaking and saturating said cleaning fabric supply roll with said solvent;
removing excess solvent from the cleaning fabric supply roll in a controlled and regulated manner prior to cleaning the cylinder of the printing press, wherein the solvent removal occurs outside a container holding the solvent; and
engaging said saturated cleaning fabric supply roll with a printing press having a cylinder to be cleaned without disposing a sleeve about said fabric roll.
