Concrete-slab press in open mould - moistens edges of final concrete layer before pressing while keeping mould frame free of water

摘要

An initial layer of concrete is delivered into the mould, followed by a final one filling the mould completely. After final filling and before pressing, water is delivered onto the final layer at least at the edges, while keeping the adjacent mould frame largely free of water. Water nozzles (5) can be mounted immediately above the mould (5) in the final filling station, delivering a predetermined amount of water. It is movable with the bag (4) delivering the concrete positions above and alongside the mould. ADVANTAGE - Fast output with clean slab edges.
