The present disclosure relates to a method for producing a leaf spring 1 for a vehicle axle suspension, wherein the at least one spring arm 5 bordering on a clamping portion 2 is formed from a rod-shaped preliminary material 7, 8 by a rolling process. By the rolling process for shaping the leaf spring a preliminary material rod 7, 8 having a rounded cross-sectional geometry is rolled out to produce a rectangular cross-sectional geometry in the clamping portion 2 and in the at least one spring arm 5, and thus the portion of the preliminary material rod 7, 8 provided for forming the clamping portion 2 in the finished leaf spring 1 is also reshaped by the rolling process and as a result a rolled structure is also formed therein.
