Abstract
A system for measuring the mass of a sheet of material including an actuator, a position sensing system, and a tactile sensor system. The actuator imparts a known force to a sheet, moving it through to the position sensing system, which measures the sheet velocity at various points. Afterward, the sheet moves through the tactile sensor system, which determines the coefficient of friction of the sheet. Given these quantities, a controller can determine the mass of the sheet, which can be used alter the performance of a reproductive machine. A second embodiment of the mass measuring system includes an actuator, a position sensing system, and a subsystem for eliminating friction. The actuator applies a force to a sheet to move it into and through the subsystem. The position sensing system incorporated in the subsystem senses the acceleration of the sheet. Given this quantity, a controller can determine the mass of the sheet.
