ABSTRACT:
There are method and apparatus for automatically clamping and cinching a flexible sheet medium on a rotatable supporting surface with clamping and cinching forces which independently increase as function of the rotational speed of the support surface. The clamp applies such forces to at least one edge of the sheet medium in a manner so that the sheet edge will not bend or push the sheet edge away from a pivot axis of the clamp so as to reduce sheet medium separation.
