An apparatus and process for the delivery of material to rolls of a laminator is disclosed.

Apparatus for supplying multiple foam machines with foam precursor chemicals. The apparatus comprises first and second totes having a top opening and a bottom drain and containing first and second foam precursor chemicals, first and second supply lines connected to the bottom drains of the first and second totes and in fluid communication with first and second sets of batcher stands, and first and second sets of batcher pumps each of which is positioned in a respective one of the first and second sets of batcher stands. Each batcher pump is adapted to be in fluid communication with a respective one of the foam machines.

A device adapted to deliver an insulation enhancing polyurethane foam within profiles used in doors, windows and related applications comprising an insulating material supply member (1) extending into a polyurethane forming and discharge member (2) adapted to enter and move linearly along a chamber (25, 35) of a thermally insulated sash or frame profile assembly and deliver therein a polyurethane foam that absolutely abuts onto the walls of the chamber without exerting undesirable stresses thereupon. The insulating material supply member (1) comprises independent pipes (8, 9) delivering a polyol constituent (A) and an isocyanate constituent (B) that are mixed together with a supply of air within a mixing compartment (4) of the polyurethane forming and discharge member (2) to produce the desired insulating material. The polyurethane supplying assembly starts injection at one end of the profile bar having an industrial standard length and moves reawards to fill the chamber with the polyurethane insulating material.

A polyurethane spraying system minimizes emissions of a polyisocyanate while spraying a mixture of a polyisocyanate and a resin composition onto a surface. The system includes a first reactant supply tank including the resin composition. The system also includes a second reactant supply tank including the polyisocyanate. The system further includes a non-gaseous pump that is coupled with the first and second reactant supply tanks, a mixing apparatus that is coupled with the first and second reactant supply tanks for mixing the resin composition and the polyisocyanate prior to spraying, and a particular spray nozzle that is coupled with the mixing apparatus. The polyurethane spraying system produces less than 50 parts of the polyisocyanate per one billion parts of air according to the NIOSH 5521 Impingement Method while spraying the mixture onto the surface.

A dual-use, low-pressure spray gun for applying one-component foam as a spray and a bead including a low-pressure canister connector and a low-pressure air hose connector. A system for applying one-component spray foam as a spray and a bead including a dual-use spray gun with a low-pressure canister connector and a low-pressure air hose connector, a compressed air supply and a compressed air hose.

A nozzle assembly includes a nozzle housing (86) defining an inner chamber (91) and a mixer (90) disposed within the inner chamber. The nozzle housing includes a nozzle housing and a nozzle orifice. The nozzle receive is configured to connect to a sprayer housing and to receive a first material, a second material, and air. The nozzle orifice is configured to spray a plural component material formed by a mixture of the first material and the second material. The mixer includes a shaft (92), an extension (94), an air channel, and inlet orifice formed in a first end of the shaft, and an outlet orifice formed between the air channel and a surface of the shaft. The extension defines a mixing channel extending between the shaft and the inner surface of the housing and the air channel is defined by an inner surface of the shaft and extends partially axially through the shaft.
