ABSTRACT:
A cement board of homogeneous composition from face to face and having a substantially uniform thickness is made continuously by distributing a sole cementitious composition on a moving carrier sheet and smoothing the surface by rotating a cylindrical roller in a direction counter to the movement of the carrier sheet. An upper reinforcing network is submerged under the surface by feeding it under the counter rotating roller.
