Abstract
A Hatschek process for the production of profiled fiber cement plates is provided. The process comprises the steps of: (i) 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: (ii) 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; (iii) removing the accumulated slab from the accumulator roll; and (iv) curing the uncured fiber cement plate.
