The invention relates to molding a right cylindrical body from a settable loose
granular composition in a mold cavity, in which a mold cavity (4) is fed
with successive charges of the composition in the loose state and each new charge
is thrust by means of thrust surfaces (11) into the surface S of the molded
composition in order to cause the new charge and the molded composition to interpenetrate
in such a manner as to densify the molded composition. The invention is applicable
to making a pipe, in particular out of a cement composition.
