ABSTRACT:
In a drum having a flexible sheet material removably held on to an outer surface thereof, a method for reducing aerodynamic lift of an edge of the material, comprising the step of introducing a thin sealing strip between the outer surface of the drum and an inner surface of the film at the edge of the material. The lift may be caused by the natural tendency of the sheet material to curl at its edges and may be exacerbated by the flow of air under the edges as the drum rotates.
