  • Method for the continuous production of plates of fibre reinforced concrete
    Patent number: 4655982
    Abstract: A method for the continuous production of plates and/or shaped bodies of fibre reinforced hydraulic setting masses is described in which the mass is provided in a predetermined thickness over the entire width of the plate to be produced, on a substrate continuously moved by a belt. Fibre cuttings from a cutting device are dispersed in a desired distribution onto the surface of the mass moving with the substrate and these are subsequently incorporated into the mass by a tool acting uniformly over the entire width of the mass. The raw plate can be further processed in its still deformable condition and brought into a desired final shape.

  • Apparatus for preparing an annular body of a hydraulically setting mass
    Patent number: 4632720
    Abstract: Steel, cast iron, synthetic resin or concrete pipes are coated with a hydraulically setting mass, such as cement mortar or a mixture of cement, fibers, aggregates and optional additives, by entraining the mass before it has set from a storage container having two opposite walls moving at about the same speed, one of the container walls being formed by a portion of the circumferential wall of the pipe being rotated about its longitudinal axis and the opposite container wall being formed by a tensioned carrier band having one end affixed to the rotating pipe and the mass with the covering tensioned carrier band being wound around the rotating pipe.
