Apparatus and method for applying a foaming reaction mixture onto a laminator

An apparatus for forming and dispensing a fluid mixture, comprising:

• a) a mixhead that includes:
• i) multiple inlets for the introduction of starting materials for mixing in the mixhead, the multiple inlets being in fluid communication with
• ii) a mixing zone in which starting materials introduced into the mixhead through the multiple inlets are combined to form a fluid mixture, the mixing zone being in fluid communication with
• iii) a mixhead outlet through which a fluid mixture formed in the mixing zone is removed from the mixhead, the mixhead outlet being in fluid communication with
• b) a distribution system for distributing and dispensing a fluid mixture exiting the mixhead outlet, said distribution system including i) a conduit system including at least one branch point at which the conduit system is divided to define multiple flowpaths and ii) outlets at termini of the multiple flowpaths of the conduit system for dispensing the fluid mixture from the distribution system;
• c) adjustable flow restriction means positioned downstream of the mixing zone of the mixhead and at or upstream of the at least one branch point of the conduit system, wherein the adjustable flow restriction means is operable to increase and decrease backpressure in the mixing zone of the mixhead.
