Abstract (en)

[origin: WO2017148551A1] The invention relates to a method for shaping a workpiece (1) having a drum-type peripheral wall (2), on the inner face (3) of which an inner profile (5) featuring longitudinal ribs (6) is formed by feeding at least one profiling roll (12) to said inner face (3). According to the invention, at least one rotatably mounted profiling roll (12) is fed to an inner face (3) of the peripheral wall (2) of the workpiece (1), and said at least one profiling roll (12) rotates relative to the inner face (3) of the peripheral wall (2) such that the inner profile (5) is formed in the inner face (3) in a non-cutting manner.
