Prefabricated floor slabs - by fixing together irregular units placed with faces in cavities of mould

摘要

Prefabricated slabs with at least one flat face with a cover motif composed of units, such as squares with irregular dimensions are produced by placing the units so that their upper face rests on the base of corresponding cavities of a mould for the desired cover motif, the bases being in the same plane, and fixing together all the units by means of their lower faces appearing above the mould. Gives floor slabs with non-uniform cover motifs. The method enables these tiles to be produced conveniently in a much shorter time.
