Abstract

797,026. Laminates. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 11, 1957 [Jan. 20, 1956], No. 1974/56. Class 140. [Also in Groups XXIII and XXVIII] Curved balsa wood members, particularly for forming a heat-insulating lining of a tank (see Group XXVIII), comprise two layers 1, 2 rigidly bonded to each other with the grain running in mutually perpendicular directions and then bent so that the axis of curvature is parallel to the grain of the layer 2 on the inner side of the curved member. A synthetic resin or rubber-based adhesive may be used for bonding the two layers provided it does not allow slip on bending. The two layers are made up of several strips 1a, 2a and the strips should preferably run the whole length of the layer but joins may be permitted in the layer 2 destined to be the inner layer, provided they do not occur opposite a join in the outer layer 1. The two layers need not be of the same thickness. For making thicker curved members, several flat two-layer members are assembled with liquid adhesive, preferably a resorcinol resin, between their surfaces and with the grain running in mutually perpendicular directions in adjacent layers throughout the assembly. The assembly is then bent with the grain of the innermost layer parallel to the axis of curvature, the members being allowed to slip over each other, and the adhesive is cured by high-frequency heating. An aluminium layer may be glued to one face of the member by a rubber-based adhesive.
