Abstract
An improved method to calculate the relative position between a plating head and an intermittently moved web of material that is to be plated wherein a nozzle directs pressurized fluid through an aperture in the web and the back pressure is monitored as an indication of the relative position of the nozzle and the aperture. Back pressure is represented digitally and a microprocessor waits an interval for the pressure to stabilize, compares the digital signal to a look up table in memory to determine the error in position, and commands movement of the plating head a distance sufficient to bring the error to zero.
