Abstract
Abstract A system is provided for making a composite block comprising a block body (a) formed of mortar or concrete and a covering material (b), such as a tile, natural stone or mortar sheet, applied to one outer surface of the block body (a). The system comprises applicator means (31,32,38,39) for applying an adhesive material (c) to the block body (a) or covering material (b), pressing means (50) for applying vibration and/or pressure to a composite block assembly (K) including the block body (a) and the covering material (b) placed thereon to compress the adhesive material (c) therebetween, and finishing means (62,63 ) for finishing the pressed composite block assembly into a composite block by passing it through an aperture (62) in a scraper (63) of flexible material, the aperture (62) being of a shape substantially the same as the exterior contour of the composite block (K).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A system for making a composite block comprising a block body (a) formed of mortar or concrete and a covering material (b), such as a tile, natural stone or mortar sheet, applied to one outer surface of the block body (a), characterised in that the system comprises applicator means (31,32,38,39) for applying an adhesive material (c) to the block body (a) or covering material (b), pressing means (50) for applying vibration and/or pressure to a compsite block assembly (K) including the block body (a) and the covering material (b) placed thereon to compress the adhesive material (c) therebetween, and finishing means (62,63 ) for finishing the pressed composite block assembly into a composite block by passing it through an aperture (62) in a scraper (63) of flexible material, the aperture (62) being of a shape substantially the same as the exterior contour of the composite block (K).
Claim 2
Independent Claim
147 words
A system for making a composite block comprising a block body (a) formed of mortar or concrete and a covering material (b), such as a tile, natural stone or mortar sheet, applied to one outer surface of the block body (a), characterised in that the system comprises applicator means (31,32,38,39) for applying an adhesive material (c) to the block body (a) or covering material (b), pressing means (50) for applying vibration and/or pressure to a compsite block assembly (K) including the block body (a) and the covering material (b) placed thereon to compress the adhesive material (c) therebetween, and finishing means (62,63 ) for finishing the pressed composite block assembly into a composite block by passing it through an aperture (62) in a scraper (63) of flexible material, the aperture (62) being of a shape substantially the same as the exterior contour of the composite block (K).
Claim 3
Dependent Claim
156 words
A system as claimed in claim 1, characterised in that the adhesive material applicator means (31,32,38,39) for applying the adhesive material (c) on the back surface of the covering material (b) of the composite block assembly (K) includes a mask sheet (32) having apertures (31) therein, a carriage (29) for relatively moving and positioning the covering material (b) with the free surface downwards and the back surface upwardly to and below the mask sheet (32), an elevator (14) for bringing the covering material (b) in contact with the mask apertures (31) when the covering material (b) is positioned relative to the mask apertures (31) and an adhesive material hopper (38) for applying the adhesive material (c) in recesses formed by the close contact of the mask apertures (31) with the covering material (b), the adhesive material hopper (38) being designed to move along the upper surfaces of the mask apertures (31) in the mask sheet (32).
Claim 4
Dependent Claim
151 words
A system as claimed in claim 1, characterised in that the adhesive material applicator means (31,32,38,39) for applying the adhesive material (c) on the surface of the block body (a) of the composite block assembly (K) includes a mask sheet (32) provided with apertures (31), a carriage for relatively moving and positioning the block body with the surface to be bonded facing upwards to and below the mask sheet (32), an elevator (37) for bringing the block body (a) in contact with the mask apertures (31) when the block body (a) is positioned relative to the mask apertures (31) and an adhesive material hopper (38) for applying the adhesive material (c) in recesses formed by the close contact of the mask apertures (31) with the block body (a), the adhesive material hopper (38) being designed to move along the upper surface of the mask apertures (31) in the mask sheet (32).
Claim 5
Dependent Claim
43 words
A system as claimed in claim 2 or 3, characterised in that the mask sheet (32) has a substantially uniform thickness in cross section and the mask apertures (31) therein comprise a line of a[pertures of the same shape and at predetermined imntervals.
Claim 6
Dependent Claim
