Abstract:
A frame for supporting and tensioning a printing screen for use within a screen printing machine, said frame comprising:a plurality of elongated frame members, each of the frame members having opposite ends, each end defining a connecting surface, each frame member adapted to operably retain an edge of the printing screen; and a plurality of connectors for coupling said frame members together, the connectors having a pair of edges each defining a connecting surface for engaging the connecting surfaces at the ends of said frame members, the adjacent connecting surfaces of at least one of the connectors and frame members being in angular misalignment, said connectors being sufficiently rigid relative to the frame members such that the angular misalignment causes the coupling of said at least one frame member to said connector to pre-camber the at least one frame member upon the engagement of said connecting surfaces.
