| abstract |
The invention relates to a device for applying a foamable reaction mixture to a moving cover layer, comprising a mixing head ( 100 ) having at least two inlets ( 200, 300 ) and at least one outlet ( 400 ) for mixing components that produce the foamable reaction mixture, and a conduit ( 410, 420, 430, 440 ) connected to the outlet of the mixing head, through which conduit the foamable reaction mixture can flow, and which has a discharge element ( 500 ), from which the foamable reaction mixture can be applied to the cover layer. The conduit ( 410, 420, 430, 440 ) is designed to include at least two configurations, which differ in the path length, which the reaction mixture flowing through the conduit covers. The invention further relates to a method for applying a foamable reaction mixture to a moving cover layer using a device according to the invention. |
