ABSTRACT:
In a process for producing leaves (20, 20′) for a leaf seal, in particular as a seal for a gas turbine, which leaves (20, 20′) are laterally delimited by a peripheral edge contour and have regions of different thicknesses (d1, d2), a simplification, without sacrificing precision, is achieved by virtue of the edge contour of the leaves (20, 20′) being cut out of a metal sheet (28) by an etching process and the regions of different thicknesses (d1, d2) also being produced simultaneously as part of the etching process.
