  • the low volatility organic compound solvent employed in carrying out the practice of this invention may vary widely and generally it includes at least one low volatility organic compound solvent which does not readily evaporate, as well as mixtures of the same with similar low volatile organic compound solvents or with normally volatile organic compound solvents.
  • suitable solvent materials of this type are organic compound solvents selected from organic oils, such as vegetable oils, citrus oil and the like. Generally, such solvent materials have a volatility in a range of from about zero up to about 30.0 percent, and preferably a volatility in a range of from about zero percent to about 20.0 percent, determined by routine testing methods.

  • a heat-sealable plastic sleeve is employed, that once the fabric roll is inserted in the sleeve, the so assembled sleeve and roll be subjected to a vacuum which draws the heat-sealable plastic sleeve into intimate contact with the wrapped fabric roll, while at the same time exhausting any air from the interior of the sleeve, and then simply heat-sealing the sleeve around the roll by application of heat to the open peripheral edges of the sleeve.
  • Known appropriate vacuum apparatus and heat-sealing apparatus may be used by simple adaptation of the same physically to accomplish apparatus of the vacuum and heat-sealing of the sleeve.
  • one or more small openings or vent holes in the sleeve, preferably located near the open edges of the sleeve, are provided to permit exhaustion of air from the sleeve as heat-sealing and heat-shrinking is accomplished, the location of such opening or openings assuming that any such opening or openings will be closed during the heat-sealing and heat-shrinking of the sleeve.
  • contact between the fabric strip and the solvent can be achieved in a variety of ways.
  • the appropriate solvent may be poured over the fabric in amounts sufficient to saturate the same while simply permitting excess solvent to drain off into a tray, or the solvent can be sprayed on the fabric.
  • the saturation step can be carried out at ambient temperature and pressure and the excess, as mentioned, simply permitted to drain off for a period of time sufficient to obtain a fabric saturated to equilibrium with the solvent.
  • the fabric strip be immersed or transported through a tank of appropriate solvent in a substantially horizontal direction either before or after, and preferably after, it has been wrapped on the core to form a roll. After saturation has taken place, the saturated fabric is preferably simply suspended in a position to permit excess solvent to drain off and be collected in a trap for reuse.
  • Wrapping of the fabric on the core to form a roll, as well as draining thereof, may also take place at ambient temperature and pressure.
  • the roll is inserted in the sealable sleeve, which can be a heat-sealable or heat-shrinkable and heat-sealable plastic sleeve, and the sleeve is sealed, and as described herein, can be heat-sealed and/or heat-shrunk and heat-sealed at a temperature sufficient to heat-seal or heat-shrink and heat-seal the sleeve around the saturated, wrapped fabric roll in contact with the fabric roll.
  • the particular heat-shrinking and heat-sealing temperature will be dependent upon the type of heat-shrinkable and heat-sealable material utilized and may extend in a range of from about the softening temperature of such material up to about the decomposition temperature of such material. Care must be taken, however, to be sure that the particular temperature employed is not so high that it will have a deleterious effect on the saturated fabric roll disposed in the plastic sleeve.
  • heat-shrinking and heat-sealing are employed, they can be achieved at temperatures in a range of from about 149°C (300°F.) up to about 204°C (400°F.), and preferably are achieved at temperatures in a range of from about 177°C (350°F.) up to about 191°C (375°F.) and may be carried out in an oven, or under heat-radiating lamps.
  • the sleeve will be sized so that the wrapped roll can be inserted therein with facility and the open edges of the sleeve then brought together in contact with each other in order to seal the same, while at the same time, being sized also so that when shrinking takes place, it will brought into contact with the fabric roll around which it is disposed.
  • the saturated wrapped fabric roll is to be employed with a slotted canister
  • the roll is simply inserted in the canister with a portion thereof protruding through the slot and the canister is provided with knock-out end portions which may be inserted therein after insertion of the roll, such end portions simply being removed when the roll is to be disposed on an appropriate shaft of a printing apparatus or the like in order to permit insertion of the shaft through the core of the roll, as well as removal of the shaft from the core.
  • the canister may be made from metals, such as light gauge steel, aluminum and the like or from cardboard or from plastic materials, such as polyethylenes, polyolefins, polyvinyl chlorides, polyamides, and the like.
  • end caps such as end cap 25
  • the end caps which may be made of the same materials mentioned above for the canister 23, are simply inserted in the open ends of the cylindrical core after the wrapping, saturation and draining steps of the method have been accomplished.
  • the terminology "saturated to equilibrium" as it is used in connection with the saturation of the fabric and/or fabric roll with solvent means that after draining the fabric and/or fabric roll retains therein sufficient solvent in an amount to wet the fabric to the extent that it imparts efficient cleaning ability to the fabric to clean cylinders of apparatus, such as printing machinery, and the fabric has retained therein after draining from about 0.008 to about 0.08 cc of solvent per cm 2 (0.05 to about 0.5 cc of solvent per in 2 ) of fabric.
  • the so-made pre-packaged, pre-soaked blanket cleaning system of this invention can be employed on any printing apparatus, simply by modifying the apparatus to provide it with a shaft which can be inserted through the core and also a take-up roll which is employed to take up the used portion of the cleaning fabric after it has carried out its cleaning function.
  • This is a distinct advantage of the cleaning system of-this invention since it eliminates the need for complex apparatus, such as pumps, spray bars, manifold lines, valves and the like, especially as part of the automatic blanket cleaning systems used on printing machinery to introduce cleansing solvents or solutions to the cleaning fabrics just prior to use.
  • the pre-packaged, pre-soaked cleaning system of this invention can be employed in combination with means such as mounting means, for positioning the system adjacent a cylinder or a plurality of cylinders to be cleaned in a simple manner. That is, for example, the system can be disposed on means provided to locate the fabric roll adjacent to and operatively associated with a cylinder or cylinders to be cleaned and the sealed sleeve can simply be removed from the fabric roll either before or after disposition of the roll on such mounting means.
  • the mounting means may also be arranged to allow disposition of the fabric roll in a position to clean a cylinder or cylinders while the fabric is in contact with and being fed past the same.
  • the cleaning system of this invention provides numerous other advantages. For example, it is relatively simple in construction, employs readily available materials and can be made in a relatively simple and forward manner without resort to highly complex and expensive procedures which necessitate the use of elaborate machinery. Numerous other advantages of this invention will be readily apparent to those skilled in the art.
