Abstract
A self-adaptive sheet feeding roll for reliably feeding, within a sheet feeding apparatus, sheets of various and different sheet weights along a sheet path. The self-adaptive sheet feeding roll includes (a) a cylindrical core having a longitudinal axis and an outer surface; (b) a compliant surface layer formed over the outer surface of the cylindrical core and having an external surface and a given layer thickness; and (c) a series of spaced apart, non-radial slots formed from the external surface into the compliant surface layer and defining a series of spaced apart blade portions within the compliant surface layer for adaptively compressing and deforming against, and responsively to, sheets of various and different sheet weights, thereby self-adjusting a normal force Fn as well as a sheet driving force Fd thereof and enabling reliable feeding, within a sheet feeding apparatus, of such sheets of various and different sheet weights.
