Abstract
A method for forming a masonry unit that includes joining a pallet to a bottom surface of a mold, inserting a filler plug into the side of the mold between a partition plate and a pallet, dispensing mix into the mold, and compressing the mix with a shoe to form a masonry unit with a filler plug effect.
Claims21
A method for forming a masonry unit, said method comprising the steps of:
- raising a pallet to a bottom surface of a mold;
- inserting a filler plug into the side of the mold between a partition plate and a pallet;
- dispensing mix into the mold;
- compressing the mix with a shoe;
- responsive to the compressing, forming a filler plug effect in the compressed mix whereby a masonry unit having a filler plug effect is provided;
- and
- responsive to the compressing, forming a substantially constant angle of inclination between a front surface and opposing side surfaces, a top surface, and a bottom surface of the compressed mix corresponding to said masonry unit to be formed by compressing the mix with the shoe against opposing side gussets and the filler plug.
