Abstract
A method for making a screen assembly for a vibratory separator, which, in certain aspects, includes placing a first layer of screening material below a glue application apparatus, and applying with the glue apparatus an amount of glue in a pattern to a portion of the first layer of screening material, unrolling part of a second layer from a second roll and positioning the part of the second layer adjacent part of the first layer to which glue has been applied, moving the part of the second layer and the part of the first layer between opposed rotatable spaced-apart rollers to press together the part of the second layer and the part of the first layer to form a pressed-together layer of first and second layers of screening material. In certain aspects hot glue is used and is cooled following application of the second layer on the first layer.
