Abstract
A method of reshaping a cylindrical pipe to a ground screw foundation for attaching an object to the ground includes a drawing unit and a working tool having a plurality of press roll disks or press roll disk segments. The press roll disks or press roll disk segments are disposed radially around a longitudinal axis of a holder for the cylindrical pipe, and pivotably around shafts extending at a fixed distance to the longitudinal axis transversely and tangentially relative to the longitudinal axis. A cylindrical pipe is inserted into a holder. The cylindrical pipe or the working tool with the drawing unit is drawn such that a relative movement between the pipe and the working tool is created.
