On each of its sides, the fabric or mesh of a printing screen is clamped by clamping means which can be drawn outwardly to stretch the fabric. So that the stretching of the fabric in one direction will not be hampered by the clamping means for the other direction of stretch, the clamping means for each side includes floating clamp portions which may separate from one another longitudinally of a pull bar by which they are carried. The pull bars are drawn outwardly (with all of the clamps thereon) for stretching the fabric. The tendency toward troublesome distortion of the strands of the fabric, and the danger of tearing the fabric (even if of metal) are thus substantially eliminated.
