Abstract
A corrugating roller unit is moved smoothly between a first reference plane and a second reference plane at different heights by a roll-out apparatus having a set of moving support device. A first moving support device supports the corrugating roller unit when the corrugating roller unit is in contact with the first reference plane. A second moving support device supports the corrugating roller unit when the corrugating roller unit is in contact with the second reference plane. A positioning device keeps the second moving support device in contact with the second reference plane when the second moving support device is providing the support for the corrugating roller unit. When the second moving support device moves the second reference plane to the first reference plane, the positioning device prevents the second moving support device from restricting movement of the corrugating roller unit. The resulting corrugating roller unit is inexpensive and does not require floor construction work at a corrugated cardboard production plant.
