ABSTRACT:
A paper machine headbox slice lip rotector system which permits limited incremental movement up or down by means of a pivoting lever arm 32 with lock bolt end portions 36 and 38 moving in adjacent protectors' adjustable keeper recesses 40. The recesses 40 are defined by stop nuts 42 on a threaded body fixed to the adjustable spindles 20. The lever arm 32 is pivotally mounted on the body for permitting up and down movement a distance which is the average of the distance defined by the keeper recesses 40 of the adjacent protectors. This prevents the prior art problem of a protector being "locked" between adjacent protectors.
