Claims

On the other hand, it is also known for profiling claims: '.' to use a rotating tool head of reinforcing bars (French patent specification

1. Reinforcing bar with ribs in opposite directions 1321167). The object of the invention is to provide a helical arrangement, characterized in that 5 reinforcing rods with high adhesion in a cone that the ribs can be produced inexpensively by continuous operation,
a coaxially driven rolling head encompassing the bar is achieved in that the rolling head with additionally driven RoI ribs are produced by a coaxial lens set on the reinforcing bar and that at least one encompassing, driven rolling head with interruptions that are identical or unequal to the ribs io driven roller sets are generated and that because of (3) in equal or unequal intervals at least one of the ribs is equal or unequal. / - ν ;; ';'.-.'.'
