1. Method for the manufacture of slabs by sawing a block of marble, granite or like material by means of a multiple-blade frame, the said method comprising the following steps:
- (a) subjecting a monolithic block to a first sawing operation by means of a multiple saw frame to form a series of preliminary slabs parallel to each other,(b) keeping the preliminary slabs joined together at least at one of their edges to maintain them in fixed relative positions, said preliminary slabs being separated by clefts made by the first sawing operation;
(c) introducing spacer material into the clefts, thus producing a composite block formed by the preliminary slabs and said spacer material, and(d) subjecting the said composite block to a second sawing operation along intermediate planes of the preliminary slabs, so as to sub-divide each preliminary slab into two final slabs.

Abstract
Thin sections of marble or like stone are made by sawing of a block to produce preliminary slabs which are held together, either by integral bridging portions, bonded base portions, or external shoring, while a spacer material, for example resin, is introduced into the clefts between the slabs. A second sawing operation then divides each slab into two halves, which can be ground and polished before separation.
