Apparatus for mixing and dispensing liquid resins

An apparatus for mixing and dispensing liquid resins, comprising:

• (a) a stationary mixer housed in a mixing unit;
• and
• (b) a dispersing unit, including means for providing delayed mixing of a first liquid resin and a second liquid resin having a viscosity greater than the viscosity of the first liquid resin, respectively flowing in a first axial direction, and for diverting flow of the first liquid resin radially and angularly with respect to the direction of flow of the second liquid resin, said means including:
• (1) a first dispersing plate crossing a line of flow upstream of said stationary mixer, having an upstream facing surface, said upstream facing surface having:
• (A) a perforationless portion having a first outer boundary,
• (B) a second outer boundary surrounding said first outer boundary in spaced relation thereto, and
• (C) at least one first perforation provided between said first and second boundaries for allowing passage of said first and second liquid resins to be mixed downstream thereof,
• (2) a first tube having:
• (A) an end fixed in abutment to said upstream facing surface along said first outer boundary so as to surround said perforationless portion of said upstream facing surface, and
• (B) at least one second perforation upstream of said first dispersing plate at said end thereof, spaced from said at least one first perforation circumferentially along the outer periphery of said first tube, for allowing passage of said first liquid resin, and
• (3) a second tube surrounding said at least one first perforation along said second outer boundary, provided upstream of said first dispersing plate, and enclosing said first tube, for allowing passage of said second liquid resin;
• whereby said first liquid resin is directed by said first dispersing plate and said first tube through said at least one second perforation radially and angularly with respect to the direction of flow of the second liquid resin and is delayed thereby in its downstream movement before passing through said at least one first perforation together with said second liquid resin.
