<p>The system produces and transfers concrete items, particularly plaster and terrazzo slabs, onto a floor surface. The prepared material is poured into a mould, compacted, turned with the mould, and set down with the mould on the floor. After compaction, the material is inverted onto the floor in the mould, which is open on one side. After this the mould can be lifted clear, and a ram be used for the mould inversion, its sliding motion being converted into a rotary one by a chain drive.</p> |
