    摘要: Plant (2) for the production of slabs made of composite stone material from a mix (M) containing granules of stone or ceramic or glass material and a binder, comprising at least one temporary support or mould (S), a distributor for the mix (M) designed to distribute a layer of mix (M) on the temporary support or mould (S), a station (4) for performing compaction by means of vacuum vibro-compression of the mix (M) arranged on the temporary support or mould (S) and a station for hardening the mix (M) so as to form the finished slabs. The plant (2) comprises a device (1) positioned downstream of the distributor and upstream of the compaction station (4) and comprising means (16) which act on the top surface of the mix (M) for pre-compaction and levelling of the mix (M) arranged on the temporary support or mould (S). The invention also relates to a method for the production of slabs of composite stone material from a mix (M).

    摘要: A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.

    摘要: Embodiments of a system and a method for manufacturing a gypsum board include a forming assembly configured to form the gypsum board to be within a predetermined thickness range and to detect vibration at the forming assembly during the continuous manufacture of gypsum board that is indicative of a hardened lump of slurry that may cause manufacturing process problems being lodged at or passing through the forming assembly. The forming assembly includes first and second forming members, an actuator, a vibration sensor, and a controller. The vibration sensor is arranged with respect to one of the first and second forming members to detect the vibration of said forming member. The controller is programmed to control the actuator to increase the height between the second forming member and the first forming member by a predetermined amount in response to the vibration signal from the vibration sensor satisfying a condition.

    摘要: The present invention is directed to a fiber cement felt comprising repeat units, each of which includes top, middle, and bottom machine direction yarns and cross-machine direction yarns interwoven with the top, middle, and bottom machine direction yarns in a predetermined weave pattern. The top, middle, and bottom machine direction yarns may comprise effect yarns and linear yarns without the need for a batt layer.
