Apparatus for processing a fluid compound for producing foam material for the manufacture of products having a cellular structure

Claim 2

Mixing apparatus as claimed in claim 1, wherein said first surface comprises the peripheral surface of a first axially elongated roll, and said second surface comprises the peripheral surface of a second axially elongated roll mounted for rotation in nip sealing relation one with the other.

Claim 3

Mixing apparatus as claimed in claim 2, wherein a said receptacle is located above said first or second surface, having an elongated opening therefrom, said surface being spaced in fluid metering relation with said opening, to control the rate of deposition of said fluid on said surface.

Claim 4

Mixing apparatus as claimed in claim 3, including first and second receptacle means having respective exits therefrom arranged in mutual metering relation with the surfaces of their respective first and second rolls to control the deposition of said fluids thereon.

Claim 5

Mixing apparatus a s claimed in claim 4, wherein one of said receptacle means to contain a fluid formed of the group hydroxy, and the other of the said receptacle means to contain a fluid formed of the group isocyanate.

Claim 6

Mixing apparatus as claimed in claim 5, wherein one of the said axially elongated rolls to receive a fluid formed of the group hydroxy from one of said receptacle means, and the other of the said axially elongated rolls to receive a fluid formed of the group isocyanate from the other of the said receptacles.

Claim 7

A mixing apparatus for mixing two different fluids formed from reactant materials in intimately admixed relation, to make a polyurethane foam, comprising a rectangular frame formed of parallel longitudinal bases, vertical walls extending upwardly from said parallel longitudinal bases and secured thereto, lever arms journaled to said vertical walls, first and second outwardly contrarotating axially elongated film-carrying rolls transversely aligned with one another and journaled to said vertical walls, drive means rotating said first and second outwardly contrarotating film-carrying rolls into converging inverted mutual nip sealing relation, first and second receptacle means formed of front, rear and sidewalls and secured to said lever arms, a plurality of transverse partitions of predetermined heights and widths secured to said front and rear walls of each of said receptacle means and extending upwardly from the lower edges of said front and rear walls and forming spacer blocks for completing a plurality of discharge openings in alignment with one another, said first receptacle means to contain a first fluid for deposition in adhering relation on said first axially elongated film-carrying roll in the form of spaced film ribbons thereon, said second receptacle means to contain a second fluid in adhering relation on said second elongated film-carrying roll in the form of spaced film ribbons thereon, an air conduit suitably supported and having a plurality of air nozzles to air spray under pressure the spaces located between the ribbons of films on said first and second axially elongated film-carrying rolls, whereby the ribbons of films maintain their distances from one another through the application of the aforesaid air sprays expelled from the air nozzles, a casting surface located beneath said nip, and means to move said casting surface past said nip at an angle inclined therefrom, whereby in operation said first and second fluids are mixed at the nip and expressed downwardly onto said casting surface, to provide substantially continuous coating of said admixed fluids on said moving casting surface.
