Claim:
A device for preparing a soaked cleaning fabric for use in cleaning a printing press comprising: means for mounting a first supply roll having a strip of cleaning fabric wound around a shaft; calendaring means for reducing the thickness and increasing the length of said strip of cleaning fabric; solvent applying means adjacent to said calendaring means for applying a low volatility, organic compound solvent which does not readily evaporate at ambient pressure and temperature to said strip of cleaning fabric for forming a soaked strip of cleaning fabric, wherein said calendaring means increases solvent's wettability and distribution in said strip of cleaning fabric; means for forming a second supply roll comprising said soaked strip of cleaning fabric, wherein the diameter of said second supply roll is not substantially increased when said calendaring means reduces the thickness and increases the length of said strip of said cleaning fabric; and an excess solvent removing means interposed between said solvent applying means and said second supply roll for removing excess solvent from said strip of cleaning fabric and obtaining said strip of cleaning fabric saturated to functional equilibrium with said solvent.
