Abstract:
1. Apparatus for producing continuously molded bodies from a molding material comprising a multitude of extrusion orifices through which during operation the molding material is extruded into continuously molded bodies, a precipitation bath and an air gap arranged between the extrusion orifices and the precipitation bath, the continuously molded bodies being passed during operation in successive order through the air gap and the precipitation bath, and a gas stream being directed in the area of the air gap to the continuously molded bodies, wherein the air gap directly after extrusion comprises a shielding zone and a cooling area separated from the extrusion orifices by the shielding zone, the cooling area being defined by the gas stream designed as the cooling gas stream, and wherein the inclination (β) of the cooling gas stream in the direction of passage is greater than the expansion (γ) of the cooling gas stream.
