ABSTRACT:
A tensioning stretched-canvas frame and method of use is disclosed characterized by the end portion of adjacent frame members having complementary cavities formed therein which receive a spring insert adapted to persistently force the frame members apart against the retention of canvas stretched taut thereover. The spring insert resists both rotation within the cavities and bending in the plane of the frame, accordingly making the assembled frame resistent to twisting between the frame members, distortion of the frame area, and warping of the frame's plane. A disposable bridging member may be temporarily used to maintain the frame members in abutting contact against the spring forces during initial stretching of the canvas.
