A hatschek process for the production of fiber cement plates

摘要

It is difficult to produce a profiled fiber cement plate with a tapered edge of uniform density. To address this problem there is described a Hatschek process for the production of profiled fiber cement plates with a tapered edge of uniform density is provided. The process comprises the steps of: • Providing an endless fiber cement multilayered slab stacking at least one monolayer of a first type having a first width and at least one monolayer of a second type of monolayers having a second width, the at least one monolayer of a second type of monolayers extending in transverse direction beyond the at least one monolayer of a first type of monolayer; • Accumulating at least one layer of the endless fiber cement multilayered slab on a profiled accumulator roll having a recess along at least part of its circumference whereby the at least first monolayer is provided within the recess; • Removing the accumulated slab from the accumulator roll; and • Curing the uncured fiber cement plate.
