Patent abstract
Cycloidal boundary conditions for aligning liquid crystalline materials are obtained by mechanical rubbing of a polymer coating. The rubbing is performed by a rubbing head rotating around an axis perpendicular to the rubbing plane while the alignment polymer film is being translated across the rubbing film such as only a linear portion of the alignment film touches the rubbing film at any given time.
