Beschreibung
Zusammenfassung:	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.
