ABSTRACT:
A method and apparatus for positioning a wedge in a web coating machine utilizes hydraulic actuating cylinders for moving the wedge and a multicylinder constant displacement pump for operating the hydraulic actuating cylinder. Valve circuits are provided to transmit trains of pulses generated by the pump to a selected port of the hydraulic actuating cylinder and a valve circuit is provided to select the cylinders of the pump utilized to operate the hydraulic actuating cylinder. Each cylinder of the pump generates volumetrically metered pulse trains of pressurized hydraulic fluid and the valve circuits transmit selected numbers of pulses from selected pulse trains to the hydraulic actuating cylinder for a time period equal to a multiple of the cycle time of the pump.
