<p>The device has a distributor head fluidically lying behind a mixing head (11), and outlet lines (17) attached to the distributor head. A static mixer mixes inert gas and components or mixture of the components. A high-pressure feed line for the inert gas is provided under increased pressure, and a measurement and control unit is provided for setting desired pressure of the components on the mixing head. The outlet lines are fixed transverse to flow direction of expandable foam at a rigid frame (16). Independent claims are also included for the following: (1) a method for production of expandable foam (2) a device for production of sandwich composite elements (3) a method for production of expanded sandwich composite elements.</p> |
