Abstract
A method for producing polymer profiles, having a varying thickness over their width and at least one longitudinal side tapering off to form a thin edge, includes of the following steps: Extruding simultaneously a plurality of the polymer profiles through a common die such that the thin edge of each one of the polymer profiles is connected to the thin edge of at least the neighboring one of the polymer profiles to form an interconnected extrudate; in a cross-section of the interconnected extrudate, providing an angle of between 45.degree. and 135.degree. between angle bisectors of neighboring ones of the polymer profiles; and separating the polymer profiles from one another after the step of extrusion.
