Abstract (en)

[origin: EP0498276A1] In the process for manufacturing mineral fibreboards, in which mineral fibres wetted with a binder are deposited on a conveyor device to form a mineral-fibre layer, in order to feed them to a continuous-flow oven, during conveyance the mineral-fibre layer is precompressed in thickness in front of the continuous-flow oven and subsequently is folded in length as a result of alternate bulging, the mineral fibres of the mineral-fibre layer are felted, and then the mineral-fibre layer is so compressed in thickness that, after hardening, it has a virtually plane surface, the mineral-fibre layer is felted in a controlled manner in particular regions, in that, when a force which can be applied to the mineral fibres is exerted, the vertical component of the force is maximised in the region to be felted. <IMAGE>
