Abstract (en)
[origin: US8539806B2] A roll-forming process for producing longitudinally toothed profiled bodies in a pot-shaped cylindrical workpiece in which, during a first rolling process (A), the pot-shaped cylindrical workpiece (1) is moved through a first rolling stage with a bottom (3) of the workpiece being rolled first. During at least one further rolling process (B, C), the workpiece (1) passes through at least one further rolling stage with an open end of the workpiece being rolled first.
