Definitions

  • Two primary methods are employed for screen printing colors upon a web of fabric or sheet material.
  • elongated stationary tables are utilized upon which the material to be printed is positioned.
  • One or more screens are movably mounted over the table so that they print in pattern repeats upon the web of fabric.
  • the process is repeated with a corresponding number of screens so that one screen is employed for each color to be printed.
  • Another type of screen printing machine which is employed frequently, utilizes the principle, whereby, the web of fabric or sheet material is advanced in steps over a printing base member or table while the screens remain stationary thereover. A series of pattern repeats are printed upon the web and each step of advancement of the web over the printing base member corresponds to a single complete pattern.
  • the solvents in the second color tend to cause the first color to run when the first color has not been allowed suflicient time to dry.
  • the wet color that remains upon the web may adhere to the screen and be improperly imprinted at another, undesirable location upon the fabric.
  • a novel apparatus for drying printing colors which comprises a heating mat interposed between the web of material and the base member.
  • the heating mat is a laminar structure which is both flexible and resilient so that the usual printing felt may be dispensed with, if desired.
  • One of the layers comprises a heating element, preferably of the electrical-resistance type.
  • a protective abrasion-resistant layer is disposed adjacent the web of fabric in order to increase the longevity of the heating element and to aid in dispensing the heat in a uniform and even manner.
  • a heat insulating layer is provided underlying the heat-ing element in order to reduce extraneous heat losses. Further, an aluminium foil may be positioned underlying the heat insulating layer for reducing heat radiation losses.
  • FIG. 1 is a side elevation showing an apparatus for drying printing colors constructed in accordance with my inventive concept
  • FIG. 2 is a perspective view showing a printing table having a blanket, heating mat, and printing felt thereon;
  • FIG. 3 is a vertical sectional view showing the printing table and heating mat thereon;
  • FIG. 4 is an enlarged vertical sectional view showing the details of the heating mat constructed in accordance with one embodiment of my invention
  • FIG. 5 is an enlarged vertical section showing another embodiment of the heating mat
  • FIG. 6 is a plan view showing one embodiment of a heating element
  • FIG. 7 is a plan view showing another embodiment of a heating element
  • FIG. 8 is an enlarged sectional view taken along line 88 of FIG. 7.
  • FIG. 1 there is shown an apparatus for drying printing colors in which a web 10 of fabric or sheet material is fed into the machine from a convenient outside source (not shown). The completed or finished web of fabric is discharged from the opposite end of the apparatus after the printing and drying processes have been completed.
  • a plurality of printing base members 12, 14, 16 and 18 are mounted in spaced relationship one to the other. Directly overlying the printing bases and firmly adhered thereto are a corresponding plurality of plates 20, 22, 24 and 26, respectively. Disposed above the plates is a heating mat 28. Generally, one heating mat is of sufiic ient length to overlay or cover a plurality of plates, as shown. Interposed between the heating mat 28 and the web of fabric 10 is a movable endless belt or blanket 30. The belt is adapted to pass over rolls 32 and 34 which are positioned in fixed space relationship one to the other. Rolls 32 and 34 are suitably mounted upon shafts 36 and 38, respectively, for rotation, and one of the shafts is driven by outside motive means (not shown).
  • each printing base 12, 14, 16 and 18 Positioned above each printing base 12, 14, 16 and 18 are a plurality of stationary screens 40, 42, 44 and 46', respectively. Each stationary screen is supplied with color which is to be printed upon the web of fabric as it passes thereunder.
  • the belt 30 is adapted to carry the web of fabric 10 between the screens and their respective printing bases. Usually, the web 1 is advanced in steps corresponding to the linear length of each complete pattern, and as the web passes beneath each screen it is imprinted with a portion of the pattern.
  • the screen 40 may print the first complete pattern, screen 42 prints the third complete pattern spaced apart from the first pattern, screen 44 prints the fifth pattern spaced apart from the third pattern and screen 46 prints the second pattern between the first and third pattern, and so forth.
  • suflicient time is allowed to elapse between the printing of two adjacent patterns for the colors to dry.
  • screen 40 may print one color while screens 42, 44 and 46 print additional colors upon the same pattern and, thus, produce a multi-colored design.
  • the web of material 10 to be printed overlays the blanket or belt 30.
  • the belting material and caliper thereof are such that heat may be transferred therethrough. Rubber or the like material may be employed.
  • the heating mat 28 is disposed adjacent the belt in an underlying position, the details of which will be more fully described hereinafter.
  • a printing felt layer 48 Interposed between plate 20 and the heating mat 28 is a printing felt layer 48. This layer is intended to absorb the shock forces when the screens print upon the web of fabric. Under some circumstances, especially when the heating mat is sufficiently resilient, the felt layer may be dispensed with.
  • a printing table or firm printing base 12 is employed to support the plate 20 as shown.
  • FIG. 3 is a vertical sectional view showing the printing table 12 and the heating mat 28 disposed thereon.
  • Electrical terminal connection 50 is provided for energizing the electrical heating mat 28 from standard commercially available power sources.
  • the heating element 52 is interposed between an abrasion resistant layer 54 and a heat insulating layer 56.
  • the abrasion resistant layer 54 may .comprise a thin plastic film which is applied by means of spraying. The choice of the type of plastic depends upon the required temperature stability due to the fact that it is in contact with the heating element 52 which has a temperature range in the order of 390 to 575 degrees Fahrenheit.
  • finely divided metallic particles may be admixed with the plastic for temperature stability purposes as well as improving the heat conduction. Since the upper surface of this layer is in contact with the moving belt it is desirable that the surface be smooth and abrasion resistant. Preferably, the thickness of this layer is in the order of .019 to .024 inch.
  • the heat insulating layer 56 may be manufactured from a glass fiber netting. The twill binding found in such material provides good pliability and the fiber glass material has a low heat conduction rate. This layer, also, acts as a heat reservoir and improves the uniform dispersion of the heat from the heating element to the web of fabric. Further, glass fiber provides adequate mechanical strength. Preferably, the thickness of this layer is .007 to .008 inch.
  • a reflecting layer 58 may be provided underlying the heat insulating layer-
  • a um num f i v n a th k ess n he rder of .004 inch may be employed for this purpose.
  • the heating element 52 may assume various forms as illustrated in FIGS. 6, 7 and 8.
  • FIG. 6 shows three longitudinally extending adjacent metallic strips 60, 62 and 64, each of which is connected to one phase of a three phase alternating current supply as shown at 66, 68 and 70 respectively. The opposite ends of the strips are each connected to a common ground connection 72, thus, forming an electrical resistance heater.
  • FIG. 7 illustrates a heating element comprising a plurality of metal and fiber Wires or threads making a netting or screenlike pattern.
  • Various weaving patterns may be employed, for example, the warp threads may consist of groups of metallic conducting Wires and the weft threads may consist of nonmetallic or inorganic fibrous material.
  • the fibrous materials act as electrical insulation as Well as providing a heat insulating layer.
  • Strips or groupings of Wires 74, 76 and 78 are each made up from a plurality of individual wires 80. Each grouping of wires are connected to one phase of a three phase electrical supply source 82, 84 and 86, respectively. The opposite ends of the groups of wires are interconnected to a common ground connection 88.
  • FIG. 8 illustrates a Weave showing conductive wires 80 intermingled with non-conductive threads 90.
  • the thickness of the heating element is in the order of .007 to .008 inch.
  • the heating mat is resistant to pressure, resilient and flexible, thus undesirable bulges or folds are not encountered therein.
  • a screen printing device comprising a base means extending along a given path and adapted to support an elongated web of material to be printed, a plurality of screen printing members spaced .along said path and each of which is positioned to print upon the web of material passing over said base means, motive means arranged to move the web of material along said base means and said screen members, and a flexible resilient mat coextensive with said base means and lying on the surface of said base means for supporting said web, the resiliency of said mat being such that it absorbs the shock forces which occur when the screen member prints upon the web, said flexible resilient mat including, as a lamination thereof, an electrical resistance heater of fabric-like material.
