REINFORCING MEMBER SUPPORT IN CONCRETE EXTRUDERS A machine for making elongated articles of con- crete or the like having reinforcing members extending therethrough, and in which at least one spiral conveyor forces concrete under pressure through a mold causing the machine to move forwardly by reaction as the material is forced against the molded portion of the article. At least one elongated reinforcing member extends through the machine and the mold, and the machine is provided with a support tube extending to the mold to receive the reinforcing member and to support the latter as concrete is directed into the machine. The support tube preferably has a longitudinal slot therein and is mounted to rotate around a longitudinal axis so that the tube can be rotated between a position with a slot opening upwardly and a position with the slot opening downwardly.
