	Purpose: Presentation of the possibilities of application of a new manufacturing method, called wedge rolls rolling (WRR) in forming of axi – symmetrical hollowed parts.Design/methodology/approach: The research work was done in a specially designed laboratory rolling mill LUW-2. During the research, hollowed parts from steel were rolled in hot forming conditions. Basic kinematical and force parameters of the process were noticed during rolling.Findings: On the basis of the conducted research it was stated that the WRR method could be used for forming of hollowed parts with the precision compared with the precision obtained in the typical cross wedge rolling processes (CWR). At the same time, it was proved that this method could be used for rolling from billets with the wall thinner than the wall given in the CWR.Research limitations/implications: The research were limited to the wedges with spreading angles within range of β = (5° ÷ 9°), with the constant values of forming angle α = 30° and relative reduction ratio δ = 1.45. In the future, it is planned to analyse the influence of changes of angle α and relative reduction ratio δ on the WRR process.Practical implications: The conducted research can be used for designing of a new industrial method of metal forming of hollowed parts.Originality/value: The innovation of this solution is based on the application of only one wedge for forming. Because of that, the WRR method is cheaper for implementation than used so far CWR processes. This method can be applied mainly in automotive and aviation industries.
