Abstract
A slice lip control mechanism for the slice lip of a head box of a paper making machine. The control mechanism has a linear actuator, a spindle extending from the actuator and a link on the lip to attach to the spindle. Movement of the actuator is thus transmitted to the lip, through the spindle, to deform the lip locally to control a head box outlet orifice whose upper edge is defined by the slice lip. The spindle includes a pressure transducer whereby the load applied to the lip by the actuator that communications with the pressure transducer through the spindle can be assessed and the lip's position calculated.
