Abstract

A spinning cone is positioned directly below a mixing head outlet to dispense and distribute a sticky mixture of polyurethane foam liquid chemical components. The mixing head and cone are reciprocated together across a longitudinally advancing metal strip to substantially uniformly distribute the mixture thereon. The procedure is practised in connection with the fabrication of overhead door insulated panels. In the prior art, plugging of dispensers would commonly occur within minutes, due to a build-up of adhering mixture on a surface followed by foaming. The spinning cone has dispensed satisfactorily for hours at a time.
