摘要： A mold for concrete products includes a grid with a plurality of cavities that are open to both sides of the grid. The grid is bonded with polyurethane about its perimeter to the inner perimeter of a frame having a central opening therein. The grid may be formed of a single unitary piece or it may be formed from a plurality of sub-grids that are each bonded to the other with polyurethane.

摘要： A concrete products forming machine including a main frame, feed drawers, die supports and mold and head assemblies. The feed drawer is moved into position over the mold using an electric belt drive system and includes a vibrating strike off plate to improve surface quality of the molded product, zoned agitators to control movement and placement of concrete, a spring loaded seal system between the walls and floor of the feed box, and quick-release agitator design with urethane sleeves to effect easy and clean removal, replacement and cleaning of the agitators. The concrete products forming machine includes torque tube and leaf spring supports to effect substantially vertical vibrational movement of the mold with air inflatable springs for controlled force between the mold bottom and the pallet. The pallet itself is vibrated from below using phased, counter rotating shafts coupled to the pallet table on which the pallet rests. Vibration induced into the pallet by the vibrating pallet table is transferred to the mold resulting in material compaction. After the molding process, the mold is lifted in a stripping process to remove the molded product for curing or drying.

摘要： A tumbler for tumbling concrete products comprises a rotatable cylindrical drum having an input end that is slightly elevated relative to an output end. Tire retread strips are placed side-by-side on the radially inner surface of the drum and extend along its length. Clamps having lateral arms extending on either side are engaged with lateral tread grooves on the strips. The clamps are bolted to the drum between adjacent strips thereby securing the strips to the radially inner surface of the drum.
