Apparatus for the production of a flowable reaction mixture

Abstract

The present invention relates to an apparatus for the production of a flowable reaction mixture of at least two flowable components which mixture forms a foam or solid material, comprising: (a) storage means for said components; (b) supply lines leading from the storage means via metering pumps to a mixing head; (c) said mixing head having a mixing chamber; (d) injection openings connected to said supply lines and opening into said mixing chamber; (e) said mixing chamber having an outlet opening downstream of said injection openings; (f) said outlet opening having an elastic outlet tube whose throughflow cross section may be varied connected thereto; said apparatus further characterized in that: (g) the outlet tube has at least one means associated therewith for deflecting said outlet tube; (h) an ejection piston is associated with said outlet tube, which piston is capable of filling the outlet tube; the contour of the inside wall of said outlet tube corresponding to the external contour of said ejection piston.
