ABSTRACT:
In a first step of the method, a pack of slabs is formed by positioning successive layers constituted by ornamental slabs of stone or equivalent material alternating with supplementary layers constituted by slabs or sheets in succession on a support base. A liquid-tight container is then formed around the pack. A peripheral space is left in the container at least around the edges of the layers of the pack. The interior of the container is then subjected to a vacuum and a settable fluid binder, such as a thermosetting synthetic resin, is introduced into the container while it is under vacuum so that the binder fills the whole of the peripheral space, penetrates the gaps between the slabs, and covers the pack of slabs. The vacuum is then released to complete the penetration of the binder and the binder is left, or made, to set so as to produce a consolidated pack of slabs in a block in which the faces of the block corresponding to the edges of the layers are covered by a hermetic covering of binder. The block thus produced is then subjected to final multiple cutting along intermediate planes of some layers to produce one or more composite panels from each zone between two consecutive cuts.
