<p>The method of manufacturing profiled fibre cement sheets includes the stages of preparing raw materials and preparing a mixture, forming and shaping the fibre cement sheets, cold pressing of the sheets, preliminary hardening of the sheets, follow-up hardening of the sheets and finishing the sheets. The equipment for manufacturing the profiled fibre cement sheet includes a device for forming and shaping the fibre cement sheets, a conveyor for preliminary hardening of the fibre cement sheets, a flow-through shelf for follow-up hardening of the fibre cement sheets, and a template painting system for finishing the fibre cement sheets. The stage of forming and shaping the fibre cement sheet utilises a seven-step device including a slurry bath 1, a mixer 2 added to the slurry bath, oil sprayers 11 and a formwork which comprises a shell 4, a vacuum chamber 5 located inside the shell 4, a covering sieve 6 which covers the outside of the work surface of the formwork, water removal channels 7 between the covering sieve 6 and the vacuum chamber 5, a vacuum pipe 8, fastening eyes 9 of the formwork, and a counterpart 10 of the formwork. The profiled fibre cement sheet has a thickness in range 1.5 to 3 mm and a relief depth in range 10 to 120 mm and includes an imitation pattern 33, an imitation edge 34, an imitation vertical joint 35, an imitation horizontal joint 36, and also a fastening opening 37, grooves 38 hindering lateral movement of water, grooves 39 ensuring proper positioning of fibre cement sheets to each other or an overhang 40.</p> |
