KingFlex Doctor Holder

Product Features

The Kingsley KingFlex holders is designed for high performance doctoring in a variety of paper machine roll positions, with a remarkably low rate of blade consumption. Pneumatic pressure provides balanced blade pressure across the roll face at all times during operation. By balancing blade-to-roll pressure and assuring a precise fit, the KingFlex Doctor assures longer blade life, which reduces downtime necessary for blade and roll maintenance. To maintain optimum doctoring during changes in machine operating conditions, loading pressures can be adjusted through the pressure-regulating panel. Air Loading cylinders are an available option to open the doctor from the roll.

Holder Construction

KingFlex holders are constructed of stainless steel with stainless loading plates, and are ruggedly built to give dependable operation under difficult conditions. On applications such as breast rolls, press rolls, breaker stack rolls, first and last dryers, sweat dryers, MG, bottom, intermediate and top calender rolls and reel drums, KingFlex holders have proved to be ecinomincal. Loading fingers, constructed of cast stainless steel for better corrosion resistance, are manufactured with blade retaining grooves. Blade tabs facilitate either front or end removal.

Precision Blade Pressure

Two pneumatic pressure tubes run the full length of the holder–the load tube which provides precise, uniform and adjustable control to the blade, and the unload tube which is used to lift the holder for blade changing. The tubes rest against loading fingers, mounted on a pivot rod. A flexible stainless steel loading plate connects all fingers in the holder. The doctor blade is inserted between the loading plate and stainless steel fingers. During operation, pneumatic pressure is applied to the loading tube, which actuates the fingers and transfers pressure to the blade tip. With the inherent flexibility of the top plate supported by separate loading fingers, the loading pressure is distributed evenly across the roll face through the doctor blade.
