ABSTRACT:
A bridle unit assigned to a rolling stand with several rolls arranged in adjustable positions below and above the strip flow, which can be moved by means of a drive from an initial position to the strip and from the strip back into the initial position, wherein the roll situated closest to the roll gap of the rolling stand can be moved by means of an additional drive from an initial position below the strip flow or from an initial position above the strip flow to the strip, such that, when the bridle unit is used for coloring the strip, the circumference of the roll deflects the strip upward or downward from the horizontal pass line and forms a bite angle above or below the pass line.
