Method of making masonry blocks
First Claim
1. A method of making a masonry block employing a mold assembly having a plurality liner plates each having a major surface that together form a mold cavity having an open top and an open bottom, wherein at least one liner plate is moveable between a retracted position and a desired extended position within the mold cavity, the method comprising:
- providing a negative of a desired texture on the major surface of the moveable liner plate;
moving the moveable liner plate to a retracted position;
closing the bottom of the mold cavity by positioning a pallet below the mold assembly;
filling the mold cavity with dry cast concrete via the open top;
vibrating the mold assembly and dry cast concrete therein;
moving the moveable liner plate toward a desired extended position after the mold cavity has been filled with dry cast concrete, before the open top of the mold cavity is closed, and while the mold cavity is vibrated;
closing the open top of the mold cavity with a head shoe assembly subsequent to commencement of the vibrating and the moving of the moveable liner plate toward the desired extended position; and
completing compaction of the dry cast concrete after the open top is closed via the vibrating and movement of the head shoe assembly and completion of movement of the moveable liner plate to the desired extended position to form a pre-cured masonry block having a surface with the desired texture imparted therto.
