Abstract
A mold for producing a masonry unit with a roughened texture side surface having a plurality of side walls defining a mold cavity open at its top and bottom, adapted to receive masonry fill material by way of its open top, and to discharge molded fill material in the form of a block of predetermined height by way of its open bottom; and opposed, inwardly extending generally parallel upper and lower lips along at least one of said side walls, the upper lip being located at a predetermined height above the lower lip and the lower lip being located at the bottom of the mold cavity.
Claims6
A method of manufacturing a masonry unit with roughened texture side surface, said method comprising the steps of:
- a) filling a mold with masonry fill to a first level, said mold comprising a plurality of side walls defining a mold cavity open at its top and bottom, adapted to receive masonry fill material by way of its open top, and to discharge molded fill material in the form of a molded masonry unit of predetermined height by way of its open bottom, and inwardly extending and generally parallel upper and lower lips along at least one of said side walls, said lower lip being located at the bottom of the mold cavity, said upper lip being located on said at least one side wall at about said predetermined height above said lower lip, said side wall being continuous without projections between said lower lip and said upper lip
- b) compacting the masonry fill within the mold to a second level corresponding with the predetermined height of the molded masonry unit;
- c) discharging the molded masonry unit from the mold such that substantially all of the masonry fill is removed from said side wall between said lower lip and said upper lip;
- and
- d) curing the masonry unit.
