ABSTRACT:
A process of molding a concrete pipe is proposed. The attainment of a predetermined degree of compactedness of fresh concrete is electrically detected through a pressing roller by which the fresh concrete is compacted in a molding flask. When a predetermined degree of compactedness of concrete is attained in one place within the molding flask, a belt conveyor for feeding the molding flask with fresh concrete is automatically moved to the next place.
