ABSTRACT:
A sheet material tensioning apparatus includes frame members interconnected one with another to define a closed contour. The apparatus applies tension to sheet material by imposing a separation between frame members to expand the closed contour. Beneficially, the sheet material tensioning apparatus includes an edge-bridging mechanism, such as a spline, to span the gap between the separated frame members. The edge-bridging mechanism maintains the continuity of the edge supporting the sheet material. The sheet material apparatus may include a crossbar assembly to add rigidity to long frame members, while maintaining planar alignment even under considerable compression.
