摘要： A fiber cement felt is includes a set of fine top machine direction yarns and a set of fine top cross machine direction yarns interwoven with the top machine direction yarns to form a top fabric layer. A set of coarse bottom machine direction yarns and a set of coarse bottom cross machine direction yarns are interwoven to form a bottom fabric layer. Seam loops merge with the bottom machine direction yarns and define longitudinal ends of the press felt. A batt layer overlies the top fabric layer. The fiber cement felt is positioned on a series of support rolls of a fiber cement forming machine, and then the longitudinal ends of the fiber cement felt is joined at the seam loops to form an endless belt. A fiber cement slurry is deposited on the fiber cement felt, and moisture is removed from the slurry.

摘要： The invention relates to a method and a device for producing fibre cement panels or moulded bodies or such like. The method provided for by the invention comprises the following steps: production of a fibre suspension from a binder which contains cement and in which cellulose fibres or similar fibres are distributed; dilution of the fibre suspension with water to a predefined concentration of solids; transfer of the diluted fibre suspension into at least one perforated cylinder box (6a, 6b), whereby the filling level of said perforated cylinder box (6a, 6b) is adjusted to a set value; application of the diluted fibre suspension onto a perforated cylinder drum (7a, 7b) located in the perforated cylinder box; transfer of the fibre-suspension layer formed on the perforated cylinder drum (7a, 7b) onto a felt strip (8); drying and pressing of the layer positioned on the felt strip (8); removal of the layer from the felt strip (8) for the production of panels or moulded bodies; measurement of the thickness of the layer removed from the felt strip; and adjustment of the bulk density of the suspension supplied to the perforated cylinder box (6a, 6b). Improved control over panel thickness is obtained by modifying the set value of the filling level of at least one perforated cylinder box (6a, 6b) in accordance with the measured thickness of the layer removed from the felt strip (8).

摘要： There are prepared cement plates with an incorporated reinforcement of fibrillated polymeric film in the form of an open net, by means of the continuous process accomplished on Hatscheck machines and comprising, in the order, the following operative steps:

a) unwinding one or more nets, each consisting of a plurality of fibrillated polymeric film layers, in an open form, from continuous reels,
b) cutting such net into pieces having a length approximately equal to the circumference of the forming roll, or a length equal to the one of the entire net wound up by the roll for each plate,
c) causing the net pieces to be impregnated by a cement mix optionally containing one or more wetting agents,
d) depositing the net pieces onto a conveyor belt on which a cement mix layer containing from 15 to 100 parts by weight of water referred to 100 parts by weight of solids, and having a thickness at least equal to that of such net,
e) subjecting the net, after its coming into contact with the cement layer, to percussion and vertical vibration actions,
f) applicating vacuum in order to remove the water in excess and to raise the compactness degree between net and cement,
g) winding the net-cement panel on a roll having a circumference equal to the length of the plate to be obtained, and simultaneous application of pressure,
h) cutting the plate at the notch around which the ends of the net pieces are arranged,
i) compressing the plate so cut.
