A roller guiding system for thin strips () at a rolling system outlet which allows a safe guiding without take-off and consequent tipping/folding of the head of the strip and without cobbles even at high feeding speeds. The system of the invention prevents the strip from impacting or sliding on the upper containment devices () or on the rollers () by its upwards or downwards movement, thus avoiding possible damages to the surface, such as scratches or lines. Furthermore, such a guiding system acts on the mechanical-aerodynamic phenomenon which causes instability in the head moving by making a self-centering guiding system which is thus suitable for improving the winding quality of the coil itself.
