Abstract:
1. A method for making a glued-together screen assembly for use in a vibratory separator, the method employing a heating apparatus, the heating apparatus comprising a control system, a plurality of heating elements spaced-apart on the heating apparatus, and a plurality of heat sensors, the plurality of heat sensors spaced-apart and movable to a position adjacent the at least one layer of screening material, the plurality of heat sensors in communication with the control system, the method comprising producing at least one layer of screening material with glue on the surface thereof, placing the at least one layer of screening material on the heating apparatus, heating the at least one layer of screening material with the heating apparatus, placing a secondary member on the at least one layer of screening material, sensing with the plurality of heat sensors temperatures of different portions of the at least one layer of screening material during heating thereof, controlling the plurality of spaced-apart heating elements with the control system in response to temperatures sensed by the plurality of heat sensors to control heat applied to the different portions of the at least one layer of screening material during heating thereof, and heating together the at least one layer of screening material and the secondary member to combine the at least one layer of screening material and the at least one secondary member forming a first screen assembly.
