ABSTRACT:
A moulding tool for making curb stones from vibrated concrete having a rather high water content, the moulding tool being designed to offer good vibration properties and safe and simple removal of the curb stone from the moulding tool despite the fact that the concrete has a troublesome tendency of adhering to the moulding tool. According to the invention such a moulding tool is characterized in that the mould cavity is defined mainly by a main member of the moulding tool, said main member being a substantially rigid unit, and by two displacable end members, and that the moulded curb stone is removable from the main member in a direction parallel to the direction of displacement of the end members, the end members having means for exerting force on the curb stone when being displaced from the moulding position.
