Abstract
The rolamite is a precision roller-band mechanism which was recently developed. The looseness of the rolamite geometry is a function of the band tension. The tight geometry and the slightly loose (small-deflection) geometry may be described by simple equations. Typical digital computer results are presented for the interroller clearance in the very loose (large-deflection) geometry. The rolamite may be made to generate forces if the band flexural rigidity is varied, or if it is precurved. An energy method is used to derive a general form of the force equation.
