Abstract (en)
[origin: WO2017021463A1] The invention relates to a casting device (100) for applying a foaming reaction mixture (10), at least comprising polyol and isocyanate, to at least a partial width of a cover layer (11), in particular for producing a compound element (1), wherein the casting device (100) comprises: a supply connection (12) for feeding in the reaction mixture (10); at least one exit slit (13) extending in a transverse direction (Q) for the exiting of the reaction mixture (10); two slit plates (14) arranged opposite one another, wherein a slit space (15) extends between the slit plates (14) in a vertical direction (H) above the exit slit (13). According to the invention, a supply channel (16) connected to the supply connection (12) is formed between the slit plates (14), which closes off the slit space (15) above the exit slit (13) in the vertical direction (H), wherein the supply channel (16) has a channel cross-section (17), the main dimension of which is larger that the width (B) of the slit space (15), such that the reaction mixture can be introduced into the slit space (15) in such a way that it is distributed over the length of the supply channel (16).
