ABSTRACT:
This invention is a clamping strip attached to a flexible sheet, such as screen printing fabric, that is shaped to enable it to lock into a channel. The strip comprises a first and a second leg joined to each other at an approximately right angle. The first leg is of a size so as to position into the recess on one side of the channel leaving enough room for at least one thickness of the flexible sheet. The second leg is of a size so as to position within the channel at the same time as the first leg is positioned. The flexible sheet is affixed to the strip and wraps around the first leg inside the recess and continues over a rounded edge above the recess. With the strip and attached flexible sheet positioned into the channel with the flexible sheet wrapped over the rounded edge, a pulling or tensioning of the flexible sheet will cause the strip and flexible sheet to become locked in the channel. As more tension is applied to the flexible sheet, the strip and flexible sheet become more firmly locked in the channel.
