Abstract

The distribution pipe and pulp guide of the head box are mounted in a box-shaped support which is rotatable within two annular bearings. The support may be rotated so as to move the pulp guide from a horizontal plane into a vertical plane, for example for cleaning purposes. In addition, the distribution pipe is removably secured to the frame so as to be moved out of the support for cleaning purposes.
