Abstract:
A method for making a screen assembly for a vibratory separator, the vibratory separator including vibration apparatus for vibrating the screen assembly to impart vibratory forces to the screen assembly for vibrating the screen assembly during use of the screen assembly on the vibratory separator, the method comprisingapplying glue in a glue pattern to at least one layer of screening material useful for screening fluid introduced to a vibratory separator, said applying done by powered moving mechanical glue application means, and applying the glue in an amount sufficient so that said screen assembly while in use on the vibratory separator is able to withstand vibratory forces imparted thereto by the vibration apparatus of the vibratory separator, wherein the glue is moisture-curing hot melt glue, the method further comprising heating the glue, and moving with powered mechanical screen movement apparatus the at least one layer of screening material beneath the powered moving mechanical glue application means.
