Abstract
An apparatus for molding concrete-blocks within a molding box which is suspended, whereby vibrations are applied to the molding box uniformly in all the directions, that is, up and down, left and right, back and forth during the molding process. Uneven distribution of the concrete aggregates is avoided and homogeneous, high density and high quality concrete-blocks can be molded efficiently. Furthermore, this apparatus is provided with means to prevent transmission of the vibrations to the apparatus body.
