ABSTRACT:
An outfit for manufacturing concrete units includes one frame, which can move along a rail-track, and two detachable forms-tilters on it. The length of the unit made in the forms can be varied. Each form has also detachable equipment (edges, dies, and dividing bars). Before stripping the units, the side edges of the form are thrown aside and the bottom edge is taken away. A detachable hinged clip which is fixed on the bottom side is moved into a working position. Then the form is turned over 90.degree., and the outfit moves to a rack. The top edge is thrown back, the clip is released, and the unit falls down on cushions. The outfit operates in the same manner on the other side of the rail-track. It is possible to manufacture in one form two or more units at the same time with corresponding increase in quantity of clips on the bottom side of the form. The present outfit can be successfully used for casting, stripping, and stock-piling without the use of a crane different types of units both at the plant and at the construction site.
