<p>The present invention relates to an apparatus for holding the upper roll of a leveller to be lifted comprising: multiple vertical beams arranged in the lateral side of each edge of the leveller, and having a horizontal groove toward the leveller; multiple horizontal pins respectively inserted into the horizontal groove of the vertical beam to mount an upper roll of the leveller; and a cylinder part respectively inserted into the horizontal groove of the vertical beam to move the horizontal pin forward and backward. When the cylinder part is tensioned and pushing the horizontal pin, one side is protruding from the horizontal groove of the vertical beam, so the upper roll of the leveller is mounted. Moreover, the cylinder part is contracted, and the horizontal pin is buried inside the horizontal groove of the vertical beam, so the upper roll of the leveller is not supported.</p> |
