Abstract: The ceiling tile suspension system is composed of a runner structure and a clip structure. The runner structure is generally trapezoidal in cross section with two flanges spaced away from a ceiling structure. The clip structure includes a flat base portion with flanges that grasp the flanges of the runner. The clip structure has a serrated edge connected to the flat base portion and the serrated edge either digs into the edge of the ceiling tile or slips into a kerf in the edge of the ceiling tile to hold the ceiling tile in position against the clip flat base portion.

Abstract: A non-woven material is applied to the surface of a woven scrim. The non-woven material is needle-bonded to the scrim. The composite structure is then embossed. The embossed pattern is placed by a heated embosser on the finished product and in the non-embossed areas, the heat of embossing causes the non-woven material to partially melt and assume a textured effect which mirrors the texture of the woven scrim.
