METHOD AND DEVICE FOR PRODUCING CONCRETE PAVING STONES AND CORRESPONDING CONCRETE PAVING STONES

摘要

The invention relates to a method and a device for producing concrete paving stones (10) which have at least one projection (12) on at least one outer face (11). This projection ensures that a joint of a predetermined width is formed between adjacent paving stones when they are laid on a surface. The at least one projection (12) is formed by a rear elastic deformation of a concrete paving stone blank whilst it still wet during stripping. The inventive device comprises shaped webs (14) with cavities or recesses (15) which correspond to the projections (12) to be formed. During the production of the concrete paving stones (10) including the projections (12), these shaped webs (14) are simply withdrawn from the concrete paving stone blanks whilst the blanks are still wet.
