摘要：
A tacking rail for retaining the border-edge zone of a sheet material under tension. The longitudinal tacking rail has a flat bottom bearing surface and is wedge-shaped in cross-section at one side. A pair of parallel wall members extend oppositely from the wedge in cross-section and define a tensioning groove therebetween which extends substantially along the entire length of the tacking rail. The border-edge zone of the sheet material is adapted to be inserted and wedged into the tensioning groove by means of an auxiliary tool so that it can be retained under tension therein.
