Abstract:
The invention concerns the production of a straight cylindrical body by molding using a loose granular material hardenable in a mold cavity, whereby successive charges of the loose composition are fed into a mold cavity (4) and each new charge is pushed with push surfaces (11) into surface S of the molded composition to provoke interpenetration of the new charge and the molded composition with the purpose of densifying the molded composition. The invention can be applied in the manufacture of tubes, particularly using a cement composition.
