Definitions

  • the applicator When applying liquids or foams to relatively wide materials, as in the finishing and dyeing of fabrics or carpeting, it is critical that such substances be uniformly distributed to the applicator.
  • the latter is an inclined plane or a curved surface onto which a film of the liquid or foam is deposited so as to move under the force of gravity and fall onto the wide material passing beneath the applicator.
  • an array of spray nozzles, or an elongated manifold with plural apertures extends across the width of the material, and the liquid or foam is directed from the nozzles or apertures onto the material being treated.
  • the invention comprises an arrangement wherein a closed cylindrical housing includes a first cylindrical member secured to the bottom of the housing.
  • a second cylindrical member passes through a housing cap.
  • This second member is concentric with, but of lesser diameter than, the first cylindrical member, and it terminates at a location spaced from the bottom of the housing.
  • An annular space is defined between the first cylindrical member and the housing, and a plurality of apertures which communicate with the annular space are provided in the housing. Liquid or foam supplied under pressure to the interior of the housing through the second cylindrical member is uniformly discharged from the housing through the apertures to separate conduits leading to an applicator.
  • the invention also includes apparatus for distributing liquid or foam comprising a closed housing, a first member located within the housing to form a trough;between the housing and the member and to form a cavity encircled by the member which forms a weir between the cavity and the trough, an inlet passing through the closed housing and into the cavity and terminating in the cavity at a position below the weir member, and a plurality of outlets comprising spaced apertures arranged in the housing for ommunication with the trough.
  • the closed housing and the member are each cylindrical and the trough therebetween is annular.
  • the distributor 10 comprises a cylindrical housing 12 containing a further cylindrical member 14 concentric with the axis of the housing but of lesser diameter so as to define an annular trough or space 16 between member 14 and the interior of housing 12.
  • the cylindrical member 14 forms a weir between the trough or space 16 and cavity 14A.
  • the top of housing 12 is covered by a cap 20.
  • a tubular member 22 passes through cap 20 and terminates within the cylindrical member 14 at a location spaced from the bottom of the housing.
  • Member 22 is concentric with housing 12 and member 14, and it has a diameter smaller than that of member 14.
  • Liquid or foam under pressure passes downwardly through the tube 22, upwardly between the tube and member 14, and then downwardly between member 14 and the interior of the housing so as to be discharged from the distributor 1 0 through apertures 18. Since the housing 12 is sealed, the liquid or foam is forced evenly through each of apertures 18.
  • the representative applicator 24 shown in Figure 1 comprises a closed end pipe 26 joined to the distributor 10 by means of a plurality of conduits 28 each connected to a separate aperture 18 of the distributor.
  • the applicator 24 is provided with a plurality of apertures 30 spaced along its length from which the liquid or foam exits onto an inclined surface 32.
  • the film of liquid or foam produced on surface 32 moves under the force of gravity to the lower edge of the inclined surface from which it falls onto the web of material 34 moving past the applicator.
  • applicator illustrated in Figure 1 comprises an elongated manifold associated with an inclined surface
  • a distributor made in accordance with the present invention may be employed with a variety of other types of applicators such as an array of spray nozzles, curved blades, slotted pipes, or the like.
