CONSTITUTION:When the initial conditions are fulfilled and then the touch of an applicator roll is confirmed, an operating output is transmitted to an actuator 17 by the control calculation of a controller 18 after a specified waiting time. A feedback control for an effective sample value PI is simultaneously carried out by calculation when the deviation is increased after the specified waiting time until the deviation is controlled within the tolerance for each specified control cycle. In addition, the measured value pV21 for the coating amt. is monitored, a feedforward signal for compensating the interference by the speed is calculated by a means 25 when the value reaches a specified limit value, the calculated value is added to the output signal in the preceding calculating cycle, and the sum is outputted to an adding means 26. The calculation control and sample value control are carried out in parallel until the speed reaches a desired value.

摘要： PURPOSE:To provide the subject labor-saving apparatus having decreased energy loss by constantly inspecting the openings of differential pressure regulation valves of pressure-regulator group of a drier drainage apparatus, and providing a setting device to set the inlet steam pressure of a medium pressure group without changing the pressure difference of the pressure-regulator group. CONSTITUTION:The valve openings of differential pressure regulation valves 10, 11 of a pressure-regulator group in an apparatus for the utilization of regenerated steam of a drier are constantly inspected by a medium-pressure group steam pressure setting device 18 for regulating the inlet steam pressure of a medium pressure group 16. When the regenerated steam of the pressure-regulator group 7 escapes to the side of a heat-exchanger 19, the regenerated steam pressure of the pressure-regulator group 7 is judged to be set to a high level compared with the inlet steam pressure of the medium pressure group 16 and the setting of the pressure is changed to decrease the inlet steam pressure of the medium pressure group 16. The inlet steam pressure and the regenerated steam pressure of the pressure-regulator group 7 and the inlet steam pressure of the medium pressure group 16 are constantly maintained in optimum balanced state to maximize the effective utilization of the regenerated steam.
