    摘要: A machine for moulding pipe in an upright stationary mould having a cylindrical troweling element rotatable within the mould and axially moveable therein. Packing means directly above the troweling element have rollers to pack the moulding material into the space between the element and the mould. Deflector bars and closure plates adjacent the roller assure proper distribution of the material.

    摘要: An apparatus for producing concrete tubes using a vertical tubular mold with a rotating piston moving upwards axially inside the mold. The piston is operated in such a manner that as the torque required for rotation of the piston decreases owing to a decrease in the supply of concrete, the rate of upward travel of the piston is decreased.

    摘要: The extruder head assembly comprises of a drive shaft connected to a troweling cylinder. A plurality of rollers are spaced around the drive shaft and above the troweling cylinder and intermittently contact an inside surface as the troweling cylinder is rotated and pulled upward. The rollers are either elliptically shaped or round positioned on an eccentric axis for intermittent contact against an inside surface of the concrete pipe. The rollers compact the concrete mixture to form the outer surface and the troweling cylinder follows the compaction by smoothing the surface. The troweling cylinder comprises a plurality of removable sections. Each section is composed of a plurality of removable and replaceable tile segments. When a tile segment breaks, the section containing the broken tile segment can be removed so that the broken tile segment can be replaced.

    摘要: A compaction head of a production machine for reinforced concrete pipes has a smoothing cylinder, non-rotatably mounted on its drive shaft, for smoothing the inside of the concrete mixture that has been filled into a vertical mold. On a covering wall of the smoothing cylinder, the rolls, for the radial compaction of a concrete mixture, are mounted axis-parallel and orbiting on a circular path around and driven by the drive shaft at a specified orbiting speed about the axis of the drive shaft and about their own axis, such that the direction of rotation of each of the rolls about its own axis is opposite to that of the covering wall also driven by the drive shaft. To prevent the concrete from being pushed along in front of the rolls during the compaction, and to assure that the concrete is compacted, without thrust, outward in the radial direction, so that the steel wires of the reinforcing cage are completely covered by concrete and that no stresses occur between the cage and the concrete, with corresponding cracks in the interior of the concrete, provision is made that the covering wall of the smoothing cylinder is mounted separately on the drive shaft so that it can rotate relative to the latter, and the rolls are driven by the drive shaft via a transmission, whose transmission ratio is chosen so that the circumferential speed of the rolls is at least the same as their orbiting speed.
