Concentric annular walls are fixed to and project upwardly from a shaft mounted disc which is adapted for high speed rotation. The inner wall extends to a greater height than the outer wall and defines a circular chamber with an annular chamber being defined between the walls. Fabric to be painted is stretched over the inner circular chamber with the excess received within the annular chamber, the fabric being retained taut over the higher inner wall by a holding hoop sealed against the outer surface of the inner wall and overlying the surrounding annular chamber.
