Abstract: An adjustable clamp frame assembly for holding different sizes of plastic sheets in a thermo form machine. The frame assembly has longitudinal and transverse beams carrying clamp units that hold a plastic sheet on the beams. The longitudinal and transverse beams are movable along rails of a rectangular frame to change the lateral distance between both the longitudinal and transverse beams to accommodate different sizes of plastic sheets.
