Title:
PREPARATION OF FIBER REINFORCING HYDRAULIC PRODUCT AND ITS DEVICE
Document Type and Number:
Japanese Patent JPS5573505
Kind Code:
A
Abstract:
The present invention relates to a continuous process for manufacturing articles comprised of fiber-reinforced hydraulically bound material. A layer of the fiber-reinforcing and hydraulically bindable materials are placed on a first endless carrier while a second similar layer is formed on a second endless carrier. The layer formed on the second carrier is deposited on the layer formed on the first carrier by reversing the second carrier and the composite layer formed as a result is thereafter given the desired shape and is hardened. A number of fibrous network structures are used with the hydraulically bindable material and the two are formed into a layer with the networks distributed in it. Water is removed from that layer by suction, while on the second carrier a number of fibrous networks are likewise supplied to be formed into a layer comprised of the hydraulically bindable material with the networks distributed in it and water is also removed by suction from this layer. The invention is applied in the manufacture of building materials used, for instance, to replace asbestos-cement sheets.
