  "abstract": "An adhesive and release liner application system and method. A bottom table is slidable with respect to a frame and a middle table is slidable with respect to the bottom table. An elevator drive subsystem between a top table and the middle table is configured to adjust the elevation of the top table relative to the middle table. An adhesive head, connected to an adhesive supply subsystem, a release liner applicator, a release liner cutter, and a staple gun are mounted to the top table for applying the adhesive to a surface of a structural member positioned adjacent the top table, for applying a release liner over the adhesive on the surface, for inserting at least one staple through the release liner and into the surface, and for cutting the release liner.",
  "claims": [
    "1. An adhesive and release liner application method comprising: providing a bottom table slidable with respect to a frame; providing a middle table slidable with respect to the bottom table; providing a top table and an elevator drive subsystem between the top table and the middle table configured to adjust the elevation of the top table relative to the middle table; providing on the top table, an adhesive head, a release liner applicator, and a release liner cutter; adjusting the position of the bottom table relative to the frame; adjusting the position of the middle table relative to the bottom table; adjusting the elevation of the top table relative to the middle table; supplying adhesive to the adhesive head and applying said adhesive to a surface of a structural member positioned adjacent the top table; and applying a release liner over the adhesive on the surface.",
    "2. The method of claim 1 further including inserting at least one staple through the release liner and into the surface.",
    "3. The method of claim 1 in the bottom table slides relative to the frame via an actuator.",
    "4. The method of claim 1 in which the middle table slides relative to the bottom table via an actuator.",
    "5. The method of claim 1 further including driving the surface of the structural member past the top table.",
    "6. The method of claim 1 in which the top table further includes a horizontal roller in engagement with the surface of the structural member.",
    "7. The method of claim 1 further including activating a vertical roller to engage the structural member.",
    "8. An adhesive and release liner application method comprising: providing a bottom table slidable with respect to a frame; providing a middle table slidable with respect to the bottom table; providing a top table and an elevator drive subsystem between the top table and the middle table configured to adjust the elevation of the top table relative to the middle table; providing on the top table, an adhesive head, a release liner applicator, and a release liner cutter; supplying adhesive to the adhesive head and applying said adhesive to a surface of a structural member positioned adjacent the top table; applying a release liner over the adhesive on the surface; and cutting the release liner.",
    "9. The method of claim 8 further including inserting at least one staple through the release liner and into the surface.",
    "10. The method of claim 8 further including adjusting the position of the bottom table relative to the frame.",
    "11. The method of claim 8 further including adjusting the position of the middle table relative to the frame.",
    "12. The method of claim 8 further including adjusting the elevation of the top table relative to the middle table.",
    "13. The method of claim 8 in the bottom table slides relative to the frame via an actuator.",
    "14. The method of claim 8 in which the middle table slides relative to the bottom table via an actuator.",
    "15. The method of claim 8 further including driving the surface of the structural member past the top table.",
    "16. The method of claim 8 in which the top table further includes a horizontal roller in engagement with the surface of the structural member.",
    "17. The method of claim 8 further including activating a vertical roller to engage the structural member."

  "description_excerpt": "This subject invention relates to a system which applies a layer of adhesive and release liner to I-joists and other building elements and engineered wood products.\n\nWhen workers deploy I-joists and other engineered wood products as structural components in buildings, the workers often manually apply adhesive to the top flange of the I-joist and then secure subflooring or other materials to the I-joist. See U.S. published Patent Application No. 2006/0101785 and U.S. Pat. Nos. 5,254,203 and 6,263,636 all incorporated herein by this reference.\n\nIn U.S. Pat. Nos. 7,918,960 and 8,915,280, both also incorporated herein by this reference, a very specific machine is used to pre-apply the adhesive and a release liner to an I-joist. In some cases, that machine is difficult to operate and failed in some instances to properly apply the adhesive and/or release liner to the I-joist flange. In some cases, the release liner had to be manually applied. Also, one or more manual adjustments to the machine was often required.\n\nFeatured is an improved adhesive and release liner application system. The preferred system better ensures the release liner is adequately applied over the adhesive on an I-joist flange. The preferred system is automated so that one or more aspects of the machine which previously had to be carried out manually are now automatically controlled.",
