Abstract
The present invention relates to a process and device for applying a reaction mixture to a moving base. The key to the invention resides in the use of compressed air to ensure even distribution of the mixture. The reaction mixture is applied via an elongated pipe-like applicator vessel which extends laterally across the moving base. A cushion of compressed air is maintained in the applicator vessel above the reaction mixture.
Claims3
A process for applying a free-flowing reaction mixture in the form of a curtain onto a moving base comprising distributing the reaction mixture which forms the curtain within an elongated pipe-like applicator vessel extending laterally across the base, which vessel has output orifices facing said base and maintaining a minimum level of reaction mixture and above that a cushion of compressed air in said applicator vessel.
A device for applying a free-flowing reaction mixture onto a moving base comprising a hollow, elongated applicator vessel provided with at least one outlet orifice, said vessel arranged downstream of a mixing device, wherein said applicator vessel is connected via a compressed air main to a compressed air source, and wherein a control valve is arranged in the compressed air main, which, together with a level indicator in the applicator vessel and a pressure regulator, forms a control circuit, whereby the pressure in said vessel is adjusted depending upon the level of reaction mixture in said vessel.
