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.

Screens for vibratory separators

Screens and screen assemblies for a vibratory separator or shale shaker, such screens and screen assemblies made by a method including applying glue in a glue pattern to at least one layer of screening material, said applying done by powered moving mechanical glue application apparatus; in one aspect moving with powered mechanical screen movement apparatus the at least one layer of screening material beneath the powered moving mechanical glue application apparatus; in one aspect, using hot melt moisture-curing glue, and in one aspect facilitating the cure of moisture-curing glue by applying moisture to it.

Glued screens for shale shakers

Methods for making screen assemblies and screens for a vibratory separator or shale shaker, such methods including applying glue in a glue pattern to at least one layer of screening material, said applying done by powered moving mechanical glue application apparatus; in one aspect moving with powered mechanical screen movement apparatus the at least one layer of screening material beneath the powered moving mechanical glue application apparatus; in one aspect, using hot melt moisture-curing glue, and in one aspect facilitating the cure of moisture-curing glue by applying moisture to it.
