Roll-out apparatus for corrugating roller

摘要

A roll unit (14) includes at its one axial end first means (25) for supporting and moving the roll unit on a floor and at its other axial end second means (26) for supporting and moving the roll unit (14) on the floor. The first supporting and moving means (25) movably supports the roll unit (14) against a first floor, while the second supporting and moving means (26) movably supports the roll unit (14) against a second floor, the level of which is different from that of the first floor. The second supporting and moving means (26) includes an auxiliary means for movably supporting the roll unit (14) against the first floor which auxiliary means is disposed at a predetermined position between the first (25) and second (26) supporting and moving means along the axial direction. The roll unit (14) further comprises means for selecting from between the auxiliary means and the second supporting and moving means (26) the means which cooperates with the first supporting and moving means (25) to movably support the roll unit (14), the selection being made by changing the level of the auxiliary means relative to the second supporting and moving means (26).
