Description of the Related Art A plate straightening machine of this type straightens a lower roll group and an upper roll group in which, for example, a small-diameter roll having a backup roll or a large-diameter roll is appropriately combined. It is built in a machine stand, and is configured so that the strips are repeatedly bent and straightened by both roll groups.

る。In such a plate straightening machine, the lower roll group is generally constructed so that it can be moved up and down by means of a rolling down device, and the lower roll group is lowered to leave a space between the lower roll group and the upper roll group. By making the width wider, the lower roll group can relatively easily perform work such as roll replacement or maintenance, but the upper roll group is stationary and the lower roll group can be lowered. However, since the work such as the roll replacement and the maintenance work is directed upward, the work is difficult. Therefore, in order to perform roll replacement and maintenance of the upper roll group online, one end of the upper frame equipped with the upper roll group is pivotally attached to the straightening machine stand on an axis orthogonal to the pass line. , With the axis as the center of rotation, the upper frame is 1
It is known to employ an inversion structure in which the upper roll group is inverted from the downward state to the upward state by rotating by 80 °.

ない。The dust and the dust that has fallen onto the strip may be wiped off each time, but the work is troublesome and takes time. For this reason, conventionally, an operator removes dust and dirt accumulated on the upper frame before the upper frame is rotated, or a canopy is previously provided above the upper frame so that the upper frame can be protected from dust. Prevents dust and dirt from adhering and accumulating. However, when the worker removes dust and dirt, it becomes a work in high places with poor footing,
Dangerous and difficult to remove easily without dust, some will fall onto the strip during removal.
When using a canopy, a gap between the top surface of the upper frame and the canopy is unavoidable, and it is possible to completely prevent dust and dirt from entering the top surface of the upper frame through the gap. Can not.
