Abstract
A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.
Claims6
A process of constructing an air tight and water tight seam, consisting of the steps occurring in the following sequence:
- cutting a sheet of material made of a selected first material into two panels;
- sealing the two panels at a respective selected edge of each of the two panels using an ultrasonic machine, forming a seam;
- coating an area adjacent to both sides of the seam and along a length of the seam with a second material selected from the group consisting of polyurethane (PU), thermoplastic polyurethane (TPU), Polyvinyl Chloride (PVC), Ethylene-Vinyl Acetate (EVA), or Polytetrafluoroethylene (PTFE);
- coating on one side of a section of tape, made of the selected first material, with a third material selected from the group consisting of PU, TPU, PVC, EVA, or PTFE;
- overlaying the seam with the section of tape;
- and
- sealing the overlaid section of tape and the seam using a radio frequency (RF) welding machine.
A manufacturing system for constructing an air tight and water tight seam, the manufacturing system constructing the air tight and water tight seam consisting of the steps occurring in the following sequence:
