Abstract: A sheet stretching apparatus is provided. The sheet stretching apparatus includes a first planar frame having a first circumferential portion having a given first radial width, a given first axial depth, a first outer edge and a first inner edge, a second planar frame having a second circumferential portion having a given second radial width, a given second axial depth, a second outer edge and a second inner edge and a third planar frame having a third circumferential portion having a given third radial width, a given third axial depth, a third outer edge and a third inner edge, wherein the third inner edge extends radially inwardly of the first inner edge and the second inner edge. An adhesive is used for adhering a flexible sheet to one surface of the first planar frame. A stretching member is attached to one surface of the third planar frame. The stretching member is adjacent to the third inner edge and is disposed radially inwardly of the first and second inner edges. The stretching member extends along the circumference of the third planar frame. Spring clips or spring clamps connect the three frames together in a superposed relationship with the first frame disposed between the second frame and the third frame and the one surface of the first frame facing the one surface of the third frame, wherein the stretching member has an axial depth such that when the three frames are connected together by the spring clips or spring clamps the sheet is stretched and held taut.
