Abstract:
A method for making a screen assembly for a vibratory separator for treating fluid containing liquid, the method comprisingplacing a first layer of screening material below a glue application apparatus for applying heated initially flowable hot melt glue, the first layer of screening material made of metal, and comprising a first metal mesh through which liquid in the fluid is passable and having a first metal mesh pattern, the first layer of screening material having a top surface with a length and a width, applying with the glue apparatus an amount of heated hot melt glue in a pattern to the top surface of the first layer of screening material, the pattern of applied glue comprising continuous lines of glue extending across the length and the width of the top surface and the pattern of glue being different from the first metal mesh pattern, positioning a second layer of screening material adjacent and in contact with the first layer to which glue has been applied gluing together the first layer and the second layer, the second layer of screening material made of metal and comprising a second metal mesh through which liquid in the fluid is passable.
