cement wall panels of a mesh reinforced plastic and fibre glass.

摘要

Building sheets consisting of cement, inert materials and additives, and reinforced with plastics mesh and alkali-resistant glass fibres of short and/or continuous type, comprising a number of superposed elementary layers consisting of a mixture of cement, inert materials and additives and each comprising as reinforcement material a plastics mesh or glass fibres. The apparatus for preparing said building sheets comprises a frame (1), a conveyor belt (2), support rollers (3) and a slide surface (4) for said conveyor belt (2), an inversion roller (5) and a drive roller (6), a possible feeder (7) for a continuous support web (8), a series of plastics mesh feeders (9), a series of feeders (16) for glass fibre originating from bobbins (18), a series of cement mix metering pumps (10) and (10 min ), a series of cement mix distributors (11) and (11 min ), and a series of smoothing devices (12) and (12 min ).
