Abstract
Abstract A concealed carpet binder bar used in conjunction with a tackless carpet strip for securing and concealing the raw edge of a carpet. The bar has a horizontal base portion, a substantially vertical portion upwardly extending from the inner edge of the base portion, the vertical portion being embossed with a plurality of vertical gussets along the length of the bar, each gusset extending from the inner edge of the base portion, and a flange portion laterally extending from the upper edge of the vertical portion. The carpet is anchored on the tackless strip, the edge is folded around the outer edge of the flange portion, and the flange portion is bent downwardly to secure and conceal the carpet edge. In another embodiment of the bar, the outer edge of the base portion is scalloped to provide alternating areas of maximum width and minimum width. In still another embodiment of the bar, the flange portion is convexly curved across its width.
