Gore (segment)

Examples

• Spherical globes of the Earth and Celestial sphere were first mass-produced by Johannes Schöner using a process of printing map details on 12 paper gores that were cut out then pasted to a sphere. This process is still often used. The gores are conveniently made to each have a width of 30 degrees of longitude matching the principal meridians from the South Pole and North Pole to the Equator.
• Parachutes and hot air balloons are made from gores of lightweight material. The gores are cut from flat material and stitched together to create various shapes.
• Pressure suit joints are often constructed of alternating gores and convolutes of material constrained by cables or straps along the sides of the joint, producing an accordion-like structure that flexes with nearly constant volume to minimize the mechanical work which must be done by the suit occupant.
• Corners in round duct-work can be created by welding or fixing gores of metal sheet to form a bend.
• Some designers use the stretched grid method to design gores that are cut out of weather-resistant fabric and then stitched together to form fabric structures.
