Claim:
A support for a flexible substrate, comprising: a first upright support member; a flexible substrate having a first end and a second end, the first end being supported by the first upright support member; a primary base; a secondary base adapted to rest upon the primary base, the secondary base supporting the first upright support member; and an assembly for connecting the secondary base to the primary base to orient the first upright support member at a selected angle, comprising: at least three upright bolts projecting upwardly from the primary base; the secondary base having a base plate with a receiving aperture for each of the bolts of the primary base; a spring being positioned over each of the bolt and sandwiched between the primary base and the secondary base, such that the base plate floats on and is supported by each spring; and nuts threaded onto each of the bolts for selectively exerting a clamping force upon the base plate against each spring via the at least three bolts to orient a second upright support member at a selected angle in order to tension the flexible substrate, the clamping force being applied by the nut on one side of the base plate and the spring on the other side of the base plate.
