A mixing device and method for generating reaction plastic, the mixing device including: a mixing chamber configured to mix reactive components to generate the reaction plastic; a discharge unit, including a discharge pipe connected to the mixing chamber configured to discharge the reaction plastic generated in the mixing chamber; a cleaning piston that is axially aligned with the discharge pipe of the discharge unit and is moveable into the discharge pipe to clean reaction plastic from the discharge pipe; a fluid supply device configured to provide a lubricant into the discharge unit via an outlet to lubricate the discharge unit, a control piston arranged within the mixing chamber and configured to control flow of the reactive components; wherein an axial direction of the control piston is oblique to an axial direction of a discharge pipe of the discharge unit.

Lubricated mixing device for reaction plastics and method for generating reaction plastics

A device and method for applying a reactive mixture comprised of at least two components to a substrate () having a spraying device () capable of generating a planar, fan-shaped spray jet () and a round spray jet (), and having a means for moving the spraying device relative to the substrate, wherein the spraying device is moved over the substrate in at least two stages, wherein in the first stage, a first application of material () is performed with reactive mixture, using the planar, fan-shaped spray jet, on the substrate, and in a further stage a second application of material (-) is subsequently performed with reactive mixture, using the round spray jet, on at least a section of the material applied to the substrate in the first application of material.
