An adjustable clamp frame for securing a work piece in a thermo-forming machine includes a pair of opposed, transverse cross members, each of which are adjustable along a continuum toward and away from one another. Each transverse cross member includes at least one clamping member for securing a work piece to the frame by clamping the respective edges thereof. The clamp frame also includes a pair of opposed, longitudinal cross members, each of which are adjustable along a continuum toward and away from one another. Each longitudinal cross member includes at least one clamping member for securing a work piece to the frame by clamping the respective edges thereof. The clamping members for each of the respective pair of opposed transverse and longitudinal cross members are adapted to be disposed on a common plane when the workpiece is secured in said frame. At least one of the pair of transverse and longitudinal cross members are movable such that the associated clamping members of the respective cross members are spaced from the common plane allowing for movement of the transverse and longitudinal cross members toward and away from on another along a full continuum defined by the clamp frame when the position of the cross members is adjusted.
