  • a basic idea of the invention is, at least in an initial phase of the radial compression of a blank, to relieve the at least one compression roller in that these side flanks of the thickened region are acted upon directly by two axial forming rollers.
  • the axial distance of the two opposing forming rollers is adjusted so that it is at least partially smaller than an axial width of the forming groove of the compression roller.
  • a particularly good friction reduction can be achieved according to a development of the invention in that the at least two axial forming rollers are switched on or delivered immediately behind and / or in front of the compression roller.

  • the axial forming rollers each have an axis of rotation which is radially directed to the axis of rotation of the blank.
  • the axial distance of the two axial forming rollers to each other is a distance which is preferably parallel to the axis of rotation of the Ronde.
  • the axes of rotation of the axial forming rollers may also be angled relative to the radial direction, so that back-upsetting is also made possible on obliquely directed flanks of the thickened edge region of the blank.
