Abstract

887,001. Laminates. ADIE, G. M. Sept. 3, 1958 [Sept. 3, 1957], No. 27840/57. Class 140. [Also in Groups X and XXII] A slab, panel or the like comprises two or more layers of closed cells, adjacent cells in each layer being connected together by a web or the like, all the cells in each layer being arranged in a symmetrical pattern so that straight lands, provided by the webs and extending across the layer, are present between the cells, the density of the layers being graded progressively, so that the slab or the like has a density which is at a maximum in the neighbourhood of one or both faces and a minimum in the neighbourhood of the opposite face, or the median plane as the case may be. The variation in density may be produced by varying the size or shape of the cells, the thickness of the cell walls, or the material of the layers. As shown in Fig. 3, rolls A 1 , A 2 , A 3 , &c. carry foils F 1 , F 2 , F 3 , &c. of thermoplastic material, e.g. polyvinyl chloride. Alternate foils F 1 , F 3 , &c. are passed between dimpling rollers B 1 , B 3 , &c. which produce a pattern of dimples or cups 16 (Fig. 4) with straight lands L 1 and L 2 therebetween. The dimples may be hemispherical, as shown, or may be truncated cones or pyramids. The foils F 2 , F 6 , &c. are passed between sprays S 1 , which spray adhesive on to them. Each group of three foils, F 1 , F 2 and F 3 ; F 5 , F 6 and F 7 ; &c. then passes through a pressing roller assembly C 1 to laminate the foils together. The foils F 5 and F 7 have larger dimples than the foils F 1 and F 3 ; the dimples in foils F 9 and F 11 are still larger. The laminated assemblies D are passed between further pressing roller assemblies C 2 where they are interleaved with foils F 4 , F 8 , &c. provided with adhesive from the sprays S 2 . Skins E of greater thickness than the foils are also coated with adhesive and fed to the rolls. Thermoplastic foils can be welded instead of being stuck, the sprays S 1 and S 2 being replaced by radiant heaters. The skins may be rigidified by the provision of thin ribs. In a modification, Fig. 6, a cellular mass 10 with protective skins 12 has applied to one side a dimpled foil with the dimples open upwards. These are covered by a foil 20 which can be stripped off as shown. Concrete or plaster 22 can then be applied, the slab acting as a shutter or form which remains attached to the cast mass. Alternatively, the skin 12 can be omitted, or the dimpled foil 18 replaced by a ribbed skin of the kind described in Specification 836,009. Foils of metal or pressed fibre may be used in place of thermoplastic material. According to the Provisional Specification, slabs can be produced from slices of foamed plastics of different densities interleaved with adhesive strips, preferably of synthetic resin. Specification 842,937 also is referred to.
