Abstract
An apparatus for dispensing a reactive foam formulation to produce laminated panels includes a mixhead, a distribution system that defines multiple flowpaths for the reactive foam to outlets fitted with nozzles. The nozzles have multiple, spaced-apart outlets arranged at angles to each other to distribute the foam formulation evenly onto a moving bottom facing layer.
Claims10
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) nozzles at the terminus of each of the multiple flowpaths of the conduit system, the nozzles each having i) a nozzle inlet in fluid communication with an associated flowpath of the distribution system, ii) multiple nozzle outlets including two terminal nozzle outlets and one or more interior nozzle outlets located between the two terminal nozzle outlets and
- iii) one or more fluid paths from the nozzle inlet to the nozzle outlets, wherein the nozzle outlets are arranged in a diverging pattern a plane wherein each nozzle outlet is at an angle of 5 to 45° from each adjacent nozzle outlet, the two terminal outlets are at an angle of 30 to 90° to each other, and the distance between adjacent nozzle outlets is 1 to 30 mm.
