<p>The invention relates to a nozzle for an extruder, having a core (1) and an at least two-part housing (2, 3), comprising a stationary main housing body (2) and an end part of the housing (3), at which the flowable mass (12) leaves the nozzle, the housing (2, 3) surrounding the core (1) in such a way that a flow channel (4) is present between the core (1) and the housing (2, 3), through which flow channel a flowable mass (12) can be discharged, characterized in that the flow channel (4) is sealed in the area of the separation between the main housing body (2) and the adjacent end part (3) by means of an elastically deformable seal (5), and the end part (3) is supported on said seal (5) such that the end part can be tilted in any direction, and to a method for changing in a specific manner or for controlling the thickness distribution of flowable masses, wherein both existing eccentric and asymmetric thickness differences can be corrected independently of each other or in a linked manner.</p> |
