Abstract:
1. A method for extruding a continuously molded body from an extrusion solution, comprising: passing the extrusion solution through an extrusion duct of a predetermined length and a predetermined diameter to an extrusion duct orifice; extruding the extrusion solution through the extrusion duct orifice to obtain an extruded, continuously molded body; passing the continuously molded body through an air gap of a predetermined air gap height; accelerating the continuously molded body in the air gap; wherein: the heat flow density Q substantially averaged over the air gap height is controlled to obtain a value wherein β is the ratio of length to diameter of the extrusion duct and the value of the control parameter α is at least 0.1.
