Abstract
A steel strip (1) comprises two to seven round steel filaments (2) lying in parallel adjacent to one another so as to form a single plane of core filaments and one or more filaments (4) which are wrapped around the core filaments in one single wrapping direction. One or more core filaments, individually, or the plane of the core filaments as a whole have residual elastic torsions to such an extent that the strip remains substantially flat over the whole length of the strip if the strip is not subjected to external forces.
