Abstract

The disclosure concerns the chamber of a head box for a paper making machine. Movable partition walls extend between the side walls of the chamber. Opposed stub shafts in the opposite side walls of the chamber carry eccentric journal pins which are received in respective partition walls, such that rotation of each stub shaft adjusts the position of the respective engaged partition wall. A second concentric pin on each stub shaft also engages the respective partition wall, whereby the eccentric pin may move the partition wall while the concentric pin may guide the movement. Appropriate longitudinally extending grooves are defined in the partition wall to absorb the motion caused by rotation of the stub shaft, which moves the partition wall with respect to the stub shaft. As appropriate, there may be respective generally mutually perpendicular longitudinally extending grooves for the concentric and eccentric pins, respectively.
