Abstract
A method for making a screen assembly for a vibratory separator, the method including, in at least certain aspects, gluing together with glue at least two layers of fine screening material, allowing the glue to set, preheating the glued together at least two layers of fine screening material, placing the thus-preheated at least two layers of fine screening material in a heating apparatus, placing a coarse mesh layer on the at least two layers of screening material on the heating apparatus, placing on the coarse mesh layer a support with heat activated material thereon for adhering the support to the coarse mesh layer, and heating the coarse mesh layer, at least two fine layers of fine screening material, and the support to adhere the support to the coarse mesh layer and to glue the at least two layers of fine screening material to the coarse mesh layer.
