What is the role of gores stitching along a canopy seam?

• A. To decorate the canopy with decorative stitching.
• B. To join gores into a full canopy, maintaining shape and load distribution.
• C. To weaken the seam intentionally.
• D. To reduce manufacturing costs.

Answer: (B)

Gore stitching along a canopy seam is what joins the individual gores into a single, inflated canopy and ensures the load is carried evenly so the shape stays true. Gores are the wedge-shaped panels that form the round canopy, and the seams linking them must be strong and precise to distribute air pressure and forces from each panel into the others and toward the suspension lines. When the stitching is done correctly, the canopy maintains its intended geometry under inflation and load, providing predictable performance and stability.

Decorative stitching would not contribute to structural integrity. Intentionally weakening a seam would be unsafe, and aiming to reduce manufacturing costs would not achieve a reliable, properly shaped canopy.
