    摘要： A process is disclosed for the continuous manufacture of cement articles containing a reinforcement of net-like polymeric structures, which comprises the steps of depositing a layer of water-cement mix on a horizontal porous conveyor belt, depositing an open-mesh, net-like polymeric structure on said layer, depositing a cement layer onto said structure, compacting the thus obtained assembly by vibrations in at least vertical sense, then compressing said assembly to reduce the water content to 25-35% by weight.
    A device is also disclosed for performing the process, comprising one or more operational units arranged in series, each one comprising, according to Fig. I, a feeder 1 for the net-like polymeric structure, an horizontal porous conveyor 7, a device 3 for guiding said structure on said conveyor, at least one feeding-dosing device 4 for the deposition of the cement mix on the conveyor or the net-like structure, a vibrator 8 which vibrates at least in the vertical sense, and a compressor 10.

    摘要翻译： 公开了一种用于连续制造含有网状聚合物结构的增强物的水泥制品的方法，其包括以下步骤：在水平多孔输送带上沉积水 - 水泥混合物层，沉积网状网状 在所述层上形成聚合物结构，将水泥层沉积到所述结构上，通过至少垂直方向的振动将由此获得的组件压实，然后压缩所述组件以将水含量降低至25-35重量％。 还公开了一种用于执行该方法的装置，包括串联布置的一个或多个操作单元，每个操作单元包括：用于网状聚合物结构的进料器1，水平多孔输送机7，用于将所述结构引导到所述 输送机，至少一个用于在输送机或网状结构上沉积水泥混合物的进料计量装置4，至少在垂直方向上振动的振动器8和压缩机10。
