- the pre-packaged, pre-soaked cleaning system described is a very stable system which can be transported and stored in a horizontal and/or vertical disposition until use without substantially disturbing the distribution of the solvent in the fabric roll and detrimentally affecting the cleaning ability of the fabric.
- the pre-soaked roll is inserted in a canister 23, provided with a slit 25 through which a portion of the fabric roll 13 can be withdrawn before the assembly is sealed in the sleeve 15.
- the system of this invention is also preferably provided with end caps, such as end cap 25, made of plastic or metal or the like disposed in the open ends of the core 11.
- end caps such as end cap 25, made of plastic or metal or the like disposed in the open ends of the core 11.
- the end caps extend over the peripheral edges of the fabric roll 13 and the sleeve 15 may extend, as shown, over the edges of the end caps, or it may extend completely around the ends of the roll 13 as shown in FIG. 1. Obviously, when a slotted canister 23 is employed, end caps will not be used.
- the sleeve is sized conveniently to accommodate the roll to be covered thereby and to be drawn or shrunken into intimate contact with the roll and heat-sealed, as needed, whether it be open at both ends or at one end only.
- the fabric from which the fabric roll is made may vary widely. For example, it may be made of paper or cloth. In those cases where a cloth fabric is employed, it may be a woven or a non-woven cloth fabric made of synthetic or natural fibers or mixtures of the same.
- suitable synthetic fibers which may be used in the cloth fabrics are polyester fibers, rayon fibers, nylon fibers, and acrylic fibers and the like.
- Exemplative, but not limitative, of the natural fibers which may be employed are cotton fibers, wood pulp fibers and hemp fibers and the like.
- paper fabrics made from wood pulp modified chemically in accordance with paper manufacturing technology are suitable, for example.
- the materials used therein exhibit high acceptability to being soaked or wetted by the low volatility organic compound solvent used to saturate the same.

- woven and non-woven fabrics suitable for use in carrying out the practice of the invention have a basis weight in a range of from about 1.5 ounces per square yard to about 6.0 ounces per square yard, a caliper thickness in the range mentioned above, a tensile strength in the longitudinal (machine) direction in a range of from about 20 lbs. per inch to about 200 lbs. per inch and in a width (cross) direction in a range of from about 15 lbs per inch to about 125 lbs. per inch.
- paper is employed as a cleaning fabric in the system of this invention, it has a basis weight in a range of from about 40 lbs. to about 90 lbs., a caliper thickness in a range of from abut 0.003 . .mils.!. .Iadd.inch .Iaddend.to about 0.10 . .mils.!. .Iadd.inch.Iaddend., a tensile strength in the longitudinal (machine) direction in a range of from about 20 lbs. per inch to about 80 lbs. per inch and in the width (cross) direction in a range of from abut 15 lbs. per inch to about 50 lbs.
- a porosity in a range of from about 1.0 second to about 10 seconds when subjected to 100 cc of low volatility organic compound solvent or water, and a stretchability in a range of from about 1.0 percent to about 6.0 percent, all determined by routine testing methods.
- 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 vegetable oils and 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.
- suitable solvents also include normally volatile organic compound solvents, that is, those which readily evaporate and which are selected from mineral spirits and aliphatic hydrocarbon solvents and the like.
- solvent materials generally have a volatility of from zero up to about 100 percent determined by routine testing methods.
- the sleeve may be made from polyethylenes, polyolefins, polyvinyl chlorides, and polyamides and the like.
- such materials are heat-sealable and/or heat-shrinkable and heat-sealable at a temperature in a range of from about 300° F. to about 400° F., and preferably in a range of from about 350° F. to about 375° F.
- the heat-sealable and/or heat-shrinkable and heat-sealable sleeve may be made from heat-sealable and/or heat-shrinkable and heat-sealable paper.
- the method for making a pre-packaged, pre-soaked cleaning system comprises contacting a strip of cleaning fabric with low volatility organic compound solvent which does not evaporate readily at ambient pressure and temperature and pre-soaking and saturating the fabric with the solvent, draining of excess solvent from the saturated fabric and obtaining a fabric saturated to equilibrium with the solvent; wrapping the drained, saturated fabric around an elongated cylindrical core having open ends and forming a roll; disposing a heat-sealable plastic sleeve around the drained, saturated, wrapped fabric roll and subjecting the sleeve to a temperature sufficient to heat seal the plastic sleeve around the drained, saturated, wrapped fabric roll in intimate contact with the fabric roll, whereby the pre-soaked, saturated fabric roll can be transported and stored vertically and/or horizontally until use without disturbing the distribution of the solvent in the fabric roll and detrimentally affecting the cleaning ability of the fabric roll.
- the fabric is preferably wrapped around the core before contacting the same with the solvent. Wrapping of the fabric on the cylindrical core can be done in any convenient manner and requires no special apparatus, a wide variety of roll making equipment being readily available for accomplishing the same.
- the roll is then inserted in a heat-sealable and/or heat-sealable and heat-shrinkable plastic sleeve and the sleeve is heat-sealed and/or heat-sealed and heat-shrunken at any appropriate temperature around the roll in intimate contact therewith.
- temperatures in a range of from about 300° F. to about 400° F. and preferably in a range of from about 350° F. to about 375° F. to accomplish the heat sealing and/or heat sealing and heat-shrinking of the saturated fabric roll in the plastic sleeve and bring the sleeve into intimate contact with the fabric roll, as mentioned above, may be employed.
- 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 for applying 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 assuring 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 elongated cylindrical 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 heat-sealable or heat-shrinkable and heat-sealable plastic sleeve and the sleeve is 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 drained, saturated, wrapped fabric roll in intimate 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 can be achieved at temperatures in a range of from about 300° F. up to about 400° F., and preferably are achieved at temperatures in a range of from about 350° F. up to about 375° F. and may be carried out in an oven, or under heat-radiating lamps.
- the plastic 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 be brought into intimate 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 0.05 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 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.
