Glue pattern screens and methods of production

A method for making a screen for a vibratory separator, the method comprising

• placing at least one layer of screening material below a glue application apparatus, the glue application apparatus including a main body and a plurality of movable glue nozzles movably connected to the body,
• applying with the movable glue nozzles an amount of glue in a pattern to at least a portion of the at least one layer of screening material by moving the movable glue nozzles over the at least one layer of screening material,
• wherein the glue application apparatus includes at least one stationary glue nozzle secured immovably to the main body, the method further comprising
• applying at least one shearable glue bead having a length to the screening material so that shearing the screening material along the length of the at least one shearable glue bead produces separate sections of the screening material,
• wherein the at least one stationary glue nozzle is a plurality of spaced apart stationary glue nozzles, each for applying a shearable glue bead to the screening material, the method further comprising
• applying a plurality of spaced-apart shearable glue beads to the screening material,
• shearing the screening material along the length of each of the plurality of spaced-apart shearable glue beads producing a plurality of separate sections of screening material,
• wherein each of the plurality of spaced-apart shearable glue beads is sheared into two bead portions, each bead portion at an edge of a resulting separate section of the screening material,
• wherein the at least one shearable glue bead is a plurality of at least four spaced-apart shearable glue beads in two spaced-apart pairs of glue beads so that shearing along the length of the at least four spaced-apart glue beads produces at least one four-sided screen with a portion of each glue bead along an edge of each of the four sides of the at least one four sided screen, the method further comprising
• shearing along the length of all four glue beads to produce the at least one four sided screen,
• wherein the plurality of at least four spaced-apart shearable glue beads is a plurality of spaced-apart shearable glue beads of sufficient number to produce from the screening material a plurality of four-sided screens by shearing each of the plurality of spaced-apart shearable glue beads, the method further comprising
• shearing along the length of all spaced-apart shearable glue beads to produce the plurality of four-sided screens.
