Definitions

  • My invention relates to the method of and apparatus for spraying webs of fabric and the like with diiferent colors.
  • My invention enables webs of material to be provided with designs which have accurate printed edges, whereby the operation is accelerated.
  • a machine for stencilling on webs of fabric or the like by means of stencils and spraying nozzles wherein during the spraying a fabric is moved therewith in stages during the pressing.
  • the web is moved by means of a stencil frame over a pressure table provided with a cushioning device uniformly and in stages together with stencils pressed thereon under rows of stationary nozzles from which are ejected differently coloured liquids and means are provided which vary the position of the stencils after each operav tion relatively to the web by an amount corresponding with the eld of each separate stencil so that each field of the web corresponding with each of these stencil fields is sprayed successively with the different colors.
  • F1g.'1 is a side elevational view of a form of the invention as expressed in the appended of construction of the machine at the end of theoperation, a part being broken away.
  • Fig. 2 is a side elevational view of the left hand part of the machine at the beginning of the operation.
  • Fig. 3 is a sectional view of the machine 85 on line III-III of Fig. 2 looking in the direction of the arrows.
  • Fig. 4 is aplan view of the left part of the l machine. ⁇
  • Fig. 5 is adiagrammatic perspective view of the means for controlling the nozzles.
  • Fig. .6 is a view of a spraying apparatus in section.
  • Fig. 7 is a sectional view of a nozzleof a 95 different form of construction to that in Fig. 6.
  • Fig. 8 is a bottom plan view of the parts shown in Fig. 7.
  • Figures 9 and 10 are longitudinal sectional 10p views of a third form of construction of the nozzle.
  • Fig. 11 is a bottom plan view of the parts shown in Fig. 10 and Fiig. 12 shows diagrammatically the spraying eld as obtained by a nozzle according to Figs. 9 t0 11.
  • a design stencil 1, 2, 3 and 4 one thereof for each color, which stencils are only apertured at those portions at which the surface of the material is to be sprayed with the colors adapted therefor, so that for example with the last stencil 4 the desired formation of the design is completed.
  • Thesepatterns are not shown in detail in the drawings as they may be of any. well known construction.
  • the spraying of the material through the stencils is effected by means of spraying nozzles A arranged in a fixed position and in a straight line over each stencil, the necessary liquid dye for the stencil or fabric surface being forced through the spraying nozzles.
  • The, spraying nozzles are automatically closed or opened at the moment at which the end -sectionV of fabric has been sprayed or the first section of fabric is to be sprayed.
  • the machine is provided with portions 7 8, and 9 of'which the middle portion 8 is removable for the purpose of varying the number1of colors to be sprayed. If a. design requires more colors thanoriginally contemplated, then for each additional color to be applied a middle portion 8 is fitted between the parts 7, 9, that is; to say the'machine is lengthened.
  • a pressure table 5 is mounted to be moved to and fro by means of rollers 10.
  • the pressure table 5 is connected by means of bell crank levers 11 and 12 to a. casing 6 supporting the patterns 1 to 4.
  • the casing 6 is guided in slots 13 of plates 14 which move up and down on the pressure table 5.
  • the pressure table 5 and the casing 6 are fitted to the frame 7, 8 and 9 for the time being.
  • an endless flexible metal grid 20 constructed in the form of a sieve, on which is located a fabric or the like band 21 formed as a cushion and corresponding with the widest web of fabric and guided therewith around the rollers 17 and
  • the grid 20 is loosely mounted between the two rollers 17 and 18 on the pressure table l5 ⁇ and before the spraying device is set into operation it is pressed firmly on the pressure table 5 by the descending stencil casing'6 and by means of the stencilsl to 4.
  • a firm intimate connection is established between the said parts, 1 to 4, 6, 19, 20, 21 and 5.
  • the pressure table 5, for example 1n the present case, is driven so as to move from right to left, all the parts 19, 2O and 21 which are pressed firmly between the stencils 1 to 4 and the pressure table 5, are also driven so that the spraying of the web of fabric 19 ⁇ through the stencils 1 to 4, which are adjusted according to the flow of color, is ei'ected slowly and in stages.
  • the cushion .band 21, tightly clamped between the web offabric 19 and the grid 20, is for the p-urpose of imparting to the materialbetween the latter and the stencils 1 to 4 a tightly closed position. This is accomplished by reason of the resilient cushioning so that the colors sprayed through the opening arranged according to the stencil design do not ow under the stencils and thus cause an indistinct smudged design to be produced on the fabric.
  • the fabric 19 is secured to remain linner tube 42 and is provided with a collar 47, spacing the outer tube 41 from the inner tube 42 the latter having slots 48 which serve to establish communication between the internal space of 41 and the internal space of the sleeve 46.
  • 49 denotes a supply pipe Jfor the compressed air which pipe extends along the machine and above each board 38. It is provided with a branch pipe 50 comiected by a sup ort 51 with the board 38.
  • Each of the branc pipes 50 is connected by a pipe 52 to the outer pipe 41 of each dye container 40.
  • valves 53 which are arranged in a row and are lconnected by levers 54 to thrust rods 55.
  • the thrust rods 55 are connected together by crank levers 56 and a rod 57 and are actuated by the reciprocating movement of the pressure table 5 by means of a projection 58 of the stencil casing 6, in such a manner that as soon as the stencils come into the right end position the valves 53- are closed, and when the stencils are moved from the right into the ler't end position, the valves 53 are opened.
  • a shaft 59 is connected to one of the thrust rods 55 by means of a lever 60 and a link 61.
  • a lever 62 secured to the shaft 59 carries a portion 62 which is connected to the lever by means of a pivot 63 so that it may be moved upwardly.
  • the portion 62 projects into the path of the projection 58.
  • the lever 62 is connected, by means of a pull member 64, to a. lever 65, the latter projecting into the path of the projection 58.
  • a spring 66 keeps the pull'member always extended.
  • the pro'ection 58 engages the lever 65 and causes, y means of the pull member, the levers 62, 62 and the shaft 59 to be turned so that the valves 53 are opened.
  • the projection 58 moves back into its right end position the portion 62 of the levers 62 and 62 yields from the projection 58 and catches again before it, so that at the following return movement the projection 58 causes the levers 62, 62 to be turned and thevalves 53 to'be closed.
  • the nozzle pro uces a circular spray.
  • the nozzle may be arranged in accordance with the construction shown-in Figures 7 and 8.
  • the nozzle portion 45 similar to that shown in Fig. 6, is also connected to the inner tube 42 and has slots 48 for the passage of the com pressed air.
  • the sleeve 46 is secured to a nut 68 by means of a cap nut 67, the nut 68 being screwed on the end of the outer tube 41 and capable of bei-ngadjusted on the tube 41 by means of a lock nut 69.
  • passages 72 which are located at enlargements 7l in the end surface of the sleeve. These passages 72 are arranged diametrically opposite to one another and are inclined downwardly, relatively to the axisof the nozzle.
  • the compresed air already partly mixes in the central hole 7 0 with the outflowing dye liquid and the conical shape of the outflowing mixture is drawn into an elongated oval by the compressed air, flowing out to the passage 72, so that the spray has a similar shape.
  • Both the passages 73 and 74 are inclined downwardly towards the axis of the nozzle but the passages 73 are arranged at a steeper angle to the axis than are the passages 74.
  • the mixture iowing out of the hole 70 is first brought into an oval shape by thecompressed air assing out of f the passages 74 whereupon on urther ow of the mixture the compressed air passing out vor' the passages 73 acts on the mixture and, as these passages are turned through .90 relatively to the first mentioned passages, they also tend to impart to the mixture an oval' shape also turned through 90.
