Abstract:
A clamp frame for securing a work piece in a thermo-forming machine, said clamp frame comprising:a pair of opposed, transverse cross members each of which are infinitely adjustable along a continuum toward and away from one another, each transverse cross member including at least one clamping member for securing a work piece to said frame by clamping the respective edges thereof; a pair of opposed, longitudinal cross members each of which are infinitely adjustable along a continuum toward and away from one another, each longitudinal cross member including at least one clamping member for securing a work piece to said frame by clamping the respective edges thereof; said clamping members for each of said respective pair of opposed transverse and longitudinal cross members adapted to be disposed on a common plane when the workpiece is secured in said frame; and at least one of said pair of transverse and longitudinal cross members being movable such that the associated clamping members of the respective cross members are spaced from said common plane while the associated clamping members of the other respective cross members remain substantially in said common plane allowing for movement of said transverse and longitudinal cross members toward and away from one another along a full continuum defined by said clamp frame when the position of said cross members is adjusted.
