Document Type and Number:

WIPO Patent Application WO/2024/081984

Kind Code:

A1

Abstract:

The invention relates to a device for setting the gap (1) of a slit die (2) for producing flat extrusion products, such as films, for example, wherein the slit die (2) has a flexible lip (3) on the length of which a plurality of adjusting elements (4) are arranged at regular intervals for setting the gap profile of the lip (3). Each adjusting element (4) comprises a drive (5), preferably in the form of a stepper motor, wherein the drive (5) activates a push rod (6) that is connected in an articulated manner to the longer arm of a two-sided lever (7), and wherein the shorter arm of the lever (7) interacts with a linearly guided pressure pin (8) that in turn acts on the flexible lip (3) in order to set the gap (1) in this region.
