A papermaking machine includes a Yankee dryer, a doctor, and a doctor blade loading control system. The doctor blade loading control system includes a first doctor loading cylinder coupled to the doctor and configured to selectively apply a loading force to the doctor, a second doctor loading cylinder coupled to the doctor and configured to selectively apply a loading force to the doctor, a first air line in communication with the first doctor loading cylinder, a second air line in communication with the second doctor loading cylinder, a first electronic pressure controller configured to control a loading pressure of the first doctor loading cylinder on the doctor based on a first loading pressure setpoint, and a second electronic pressure controller configured to control a loading pressure of the second doctor loading cylinder on the doctor based on a second loading pressure setpoint.

Doctor control systems for papermaking machines and related methods

A paper machine configured as a swing machine capable of producing both light and heavy grades providing a Yankee hood split into a wet end half and a dry end half, at least one hood half being a flex-hood half wherein the supply for that half is capable of being run with either combustion heat or recycled heat and is capable of either recirculating the exhaust from the hood or discharging it to the atmosphere. The heater for the flex-hood half comprises both a primary combustion heat source and an indirect heat source capable of extracting by-product heat from another operation. The exhaust system for the flex hood half is capable of being run in either a straight through mode or in a recirculating mode.
