ABSTRACT:
A unitary, thin wall, pliable extruded plastic frame and mesh protector for protecting a circular screen printing frame member and a screen mesh in contact therewith includes integrally a circular cross-section body portion having a radius R corresponding to the exterior radius of the frame member, extends about 270.degree., and is sized to the outer periphery of the frame member. An integral base portion extends from a first end of the body portion outwardly and tangentially therefrom. A straight arm portion may extend from a second end of the body portion, at an angle of about 45.degree. to the tangent thereto toward a plane defined by a printing screen mesh whose peripheral edge overlies the base portion. A first hinge couples a proximate end of the arm portion to the second end of the body portion to facilitate pivoting of a distal end of the arm portion into contact with the facing surface of the printing screen mesh. The arm portion may be of a length equal to a hypothenuse of a right triangle whose opposite sides are of a length equal to the radius R.
