Definitions

  • This invention relates to printing blankets and especially to -blankets adapted for use on screen print machines.
  • Printing blankets used on screen print machinery are very large, and are enormously heavy. Frequently they are some 100 inches wide, and 100 yards long. Such blankets are formed in a closed loop. The material which is to be screen printed is glued to the blanket, and as each color step is imprinted on the goods, the blanket is advanced through one repeat pattern. As a consequence, the entire -blanket must start, move, and stop with an extraordinary degree of exactitude. lf the variation in an entire traverse of the loop at any point exceeds 40 thousandths (0.040) of an inch, interior printing will occur.
  • the present invention produces a blanket in which movement of the working surface is inconsiderable and makes it possible to operate a screen printing machine with blanket lengths of 100 yards without mechanical correcting devices.
  • the operating speed can be 800 yards per hour or more, yet at this speed the blanket maintains the necessary tolerance of no greater than 15 thousandths (0.015) of an inch at any point in the whole blanket run.
  • the process of screen printing is essentially a stencil operation and so differs materially ⁇ from the engraved roller rotary textile printing process.
  • Screen print blankets do not have to withstand the enormous compressional load which, in roller printing, is imposed by the color rolls. Their working surfaces do not have to withstand the compressional wave which travels along the blanket, and, in contrast to a roller press textile print blanket, they do not have to transmit any significant amount of power, for in roller type textile printing, much of the auxiliary 3,418,864 Patented Dec. 31, 1968 equipment, particularly the blanket washer, is driven by the blanket itself.
  • the only demands on a screen printing blanket are that it shall remain tight, at, have substantially no tracking error, and be strong enough to move itself, without variable stretch.
  • the critical position where linear displacement must be prevented is at and adjacent to the surface which is in contact with the drive roll.
  • the blanket is either pushed or pulled as it moves ahead, step by step.
  • a base ply of duck is coated on one side with a vulcanizable rubber compound. This forms the base or cylinder ply of the blanket.
  • Two pulleys are arranged so that the cylinder ply, when stretched over them, forms a loop.
  • the ends of the fabric are then spliced together.
  • Subsequently power is applied to ⁇ one of the pulley shafts and the ply is tensioned in small successive increments until the tension of the fabric is about 10- pounds per transverse inch.
  • the running-in of the ply is continued under tension until no slack develops and the ply maintains an exact length.
  • the time of run-in is variable, depending on the tightness of weave of the canvas.
  • an essentially non-stretchable cord which previously has been coated with a rubber compound is laid on the rubber-covered surface of the cylinder ply with tension maintained on the ply.
  • a continuous length of this cord is helically wound from the center to the margin.
  • two windings are simultaneously wound from the center outwards-one extending to the left and the other extending to the right hand margins of the ply.
  • the tension of the cylinder ply with attached cords is then increased to generally between about 20 to 40 pounds and preferably about 25 pounds.
  • a ply of duck coated on both sides with a vulcanizable rubber compound is laid over the cords and is spliced at a point remote 4from the splice in the cylinder ply.
  • a further (third) ply of duck, coated with a vulcanizable rubber compound is then laid on the cordcovering layer and is spliced at a point remote from the two underlying splices.
  • the top surface of this third ply is coated with a heavy coat of a solventresistant rubber compound which, when press-curing is complete, forms the working surface of the blanket.
  • the entire assembly or sandwich is then press-cured under quite heavy pressures in a heated vulcanizing press. As the blanket cures and the rubber flows, the cords become totally embedded in rubber compound.
  • the covering plies of duck are entirely embedded and the top or working surface of the blanket becomes a smooth, unbroken rubber sheet.
  • the top rubber coating can be omitted.
  • the cord winding, superposed on the cylinder ply be two opposed helices starting from the center and running outwardly to each margin.
  • the cord winding may then be wound uninterruptedly from one selvage to the other.
  • FIG. l is a perspective view of a portion of the blanket 10.
  • FIG. 2 is an exploded sectional view.
  • the cylinder ply, 12 carries a rubber coating, 13 (which later forms part of the rubber embedment of the cords).
  • the helices, 14, of rubbercoated cords are wound on top of rubber coating, 13.
  • the covering ply, 15, carries a rubber coating on each face.
  • the top surface of ply, 19, carries a rubber coating, 21, which later becomes the working surface.
  • the number of plies is not critical. Another or even more intermediate plies may be added if required. Ply, 19, can be omitted, provided ply, 15, is dense and very tightly woven. Usually, however, its presence is an advantage.
  • the rubber layers are indistinguishable and f-orm a solid rubber mass in which all of the fibrous elements, whether cords or fabric, are embedded.
  • the rubber flows. It thoroughly interpenetrates all of the space between the strands of the textile, and in many places penetrates deeply into the interber spaces of the textile strands themselves.
  • the cords are completely embedded in the rubber which has flowed around them.
  • the surface of the blanket, which is cured against a polished sheet, is smooth and free of any Cil surface imperfection. The cords, save for the surrounding rubber, take up a position which is immediately adjacent to the cylinder ply.
  • Example l A base ply of No. l2 duck was coated on one side with yapproximately "710 of a pound per square yard of vul-canizable neoprene rubber compound (Neoprene Type WRT, E. I. du Pont de Nemours & Co., Inc., Wilmington, Del.). Two pulleys were then set up so that when this cylinder ply was stretched over them, the loop which was formed was 40 yards long. The fabric was then spliced. Subsequently, power was applied to one of the pulley shafts, and the loop was tensioned in small successive increments until the tension of the fabric Was l0 pounds per transverse inch.
  • a base ply of No. l2 duck was coated on one side with yapproximately "710 of a pound per square yard of vul-canizable neoprene rubber compound (Neoprene Type WRT, E. I. du Pont de Ne
  • the pitch of the cord was such as to maintain a uniform spacing between the cords of 1/8 of an inch. During the entire winding, the tension applied to the cord was maintained at a uniform value. Thereafter, a ply of No. 12 duck, coated on its under side with 5%@ of a pound per square yar-d of a vulcanizable neoprene compound (Neoprene Type WRT) and having its upper side coated with i710 of a pound per square yard of a second neoprene compound (Neoprene Latex Type 571, E. I.
  • du Pont de Nemours & Co., Inc., Wilmington, Del. was laid over the cords and spliced at a point remote from the splice in the cylinder ply.
  • a third ply of duck, coated with 2/10 of a pound of neoprene compound (neoprene latex type 571) on its under side and having its top surface coated with sufficient butadiene-acrylonitrile rubber (Hycar 1051, high acrylonitrile, B. F. Goodrich Company, Cleveland, Ohio) to produce a surface 0.015 of an inch thick was laid over the cord covering layer and spliced at a position remote from the two underlying splices.
  • the whole blanket was then passed through a vulcanizing press, with a polished metal sheet interposed between the top platen and the top surface coat of rubber.
  • the blanket was vulcanized at 310 F. under a 500 pounds per square inch pressure.
  • Example Il A smaller test blanket was constructed in the same manner as that used for construction 'of the blanket of Example I. Samples one inch wide by 18 inches long, some of which contained a fabric splice and others containing no splice, were placed in a tensile test apparatus, so arranged that the tension load could be varied at a given instant and thus simulate the load change in stopping and in starting a screen print machine. The deviations in stretch were carefully measured in a series of such pulls exerted on eaoh of the samples. At equilibrium conditions, both the spliced and the unspliced sections of the blanket of Example II showed essentially no deviation in stretch.
  • samples one inch wide and 18 inches long were lcut from a blanket now commercially employed. These samples were tested in the same machine and in the same manner.
  • the deviation in extension of the spliced sample when compared to the deviation in extension of an unspliced sample when undergoing a load of 10 pounds per inch width to pounds per inch Width, was 0.025 in. (25 mils).
  • an additional deviation in extension of 0.017 in. (17 mils) occurred.
  • Example I The large blanket of Example I was placed on an Ichinose automatic screen printing machine. Extremely diflicult patterns were selected from a number which previous experience had shown could not be run on the machine because of mis-registration. Various repeat lengths and speeds were evaluated in printing runs which totaled 100,000 yards. No repeat pattern deviation was found in any run which varied from the above-mentioned i0.015 in limits.
  • glass cords particularly useful as cords in the present invention are glass cords.
  • the low stretch of the glass cord permits the construction of a blanket having less loverall stretch and 100 percent elastic recovery and, therefore, greater repea accuracy than blankets with, for example, rayon cords. Since glass cords have more strength per unit diameter than other substantially nonstretchable cords, glass cords of smaller diameter can be used which exhibit considerably less tendency to show through the surface of the top ply of the finished blanket after curing and which still will provide the necessary strength and dimensional control.
  • the glass cords laid on the cemented cylinder ply may crimp in passing around the circumference of the end rolls during the construction of the blanket, it may be desirable to apply a greater degree of tensioning to the carcass during the assembly of the blanket and during the cure than is applied to a blanket of nonglass cords.
  • the degree of tension maintained during the application of the top plys and the cure is a variable depending upon the diameter of the cord and the diameter of the end roll. In a preferred embodiment 20 to 40 pounds per transverse inch is applied and more preferably, about 25 pounds.
  • Example III A base ply of No. 12 duck was coated on one side with approximately A0 of a pound per square yard of vulcanizable butadiene-acrylonitrile rubber compound (Hycar 1051, high acrylonitrile, B. F. Goodrich Company, Cleveland, Ohio). Two pulleys approximately inches in diameter were then set up so that when this cylinder ply was stretched over them, the loop which was formed was 24 yards long. The fabric was then spliced. Subsequently power was applied to one of the pulley shafts, and the loop was tensioned in small successive increments until the tension on the fabric was 10 pounds per transverse inch. Run-in was continued until, under a tension of 10 pounds per transverse inch, no slack developed and the ply maintained an exact length.

  • Each of the cords was maintained under a tension during the Winding of approximately 1 pound, and this tension was maintained at a uniform value throughout the entire winding operation.
  • the wound loop, or carcass was then removed from the winding frame and taken to a lay-up and vulcanizing assembly station. Two rolls approximately 10 inches in diameter were arranged in a similar set-up to those used in the run-in and cord-winding operation. In this case, however, the rolls were so arranged in front and behind the vulcanizing press that the loop passed through the press. The axle of one of the rolls was then jacked backwards until the tension applied to the carcass between the lrolls was 25 pounds per transverse inch. A ply of No.
  • the use of the blanket of this invention on screen printing machines particularly those which use a simple endroll drive such as the Ichinose and the Stork machines, eliminates the need of mechanical stops, steel belt reinforcements, or other more complicated beltadvancing equipment.
  • the only mechanical stop equipment required is that used to control the movement of the drive roll.
  • color registration is remarkably Well sustained from repeat to repeat throughout the Whole piece of goods.
  • the rubber compounds which were employed ⁇ are those conventionally used in textile print blanket manufacture, and considerable variability in the choice of suitable compounds exists. Thus, it is possible to use compounds which lie within the production experience or compounding preference of an experienced textile blanket manufacturer.
  • the rubber-coated plies may be cold pressed to ensure the adhesion of the rubber to the adjacent layer or the rubber-compound may be ⁇ of the pressure-sensitive type to obviate such cold pressing.
  • rubber has been used in a generic sense and implies no chemical significance whatever. It signifies only long-chain, vulcanizable polymeric substances of whatever chemical origin which possess the requisite physical properties of exibility, resilience, :or resistance to the colors and solvents used in the screen printing process.
  • a blanket adapted for use 4on roll drive screen printing machinery and capable of maintaining the deviation of repeat pattern register to within 1.015 inch per blanket revolution which consists of a rubber-coated cylinder ply rendered dimensionally stable by running-in and stretching under a tension of about 10 pounds per transverse inch, a helix of rubber-coated cord wound about the exposed surface of said cylinder ply at a cord tension not in excess of 2 pounds and extending across the said surface, and at least a second coated ply covering said helical layer of cords, the said blanket having been cured under heat and pressure to produce a unitary blanket structure presenting a smooth working surface.
  • a blanket as claimed in claim 8 wherein the helix of rubber-covered cord is composed of glass cord wound on said cylinder ply under tension applied to the cord not exceeding l pound, the said cords being free of crimping within the blanket structure when passing around the blanket driving rolls.
