Device for tensioning sheet members

摘要

The device for tensioning sheet material applies a tensioning force around the outer edge of a sheet material to prevent the sheet material from wrinkling. These devices are attached to a supporting member forming the outer frame of a structure upon which the sheet material is to be attached and consist of tape strips or wires attached to or free sliding along the support member, sheet material of a differing material wrapped around the support member and attached to the main sheet material, with or without holes or slots, and extensions of the main sheet material around the support member, with or without heat created depressions along the border to relieve tearing stresses. Another tensioning member is a corner brace between perpendicular segments of the supporting member to remove wrinkles caused by manufacturing irregularities.
