ABSTRACT:
An improved printing screen stretch frame of the kind having rollers which grip the screen edges and are rotatable to stretch the screen edgewise. The rollers have a unique sealed tubular construction and are coupled at their ends to roller support brackets in a novel way which minimizes or eliminates many costly machining operations that are involved in fabricating conventional stretch frames. The preferred stretch frame has four roller mounting brackets situated at the four corners of a rectangle and rollers coupled at their ends to the adjacent brackets to form a stretch frame consisting of only the rollers and roller mounting brackets.
