发明名称 Flexible two-ply flooring system
摘要 A two-ply flooring plank is disclosed having two layers or "plies" with a bottom layer having a grain that runs generally transverse to a top layer or "cross-ply" to provide dimensional stability to the plank. The bottom layer includes a number of strips secured to the bottom of the top layer. The bottom layer strips are also placed with gaps between the individual strips of the second layer to allow flexibility of the flooring plank, which allows the flooring to more easily conform to irregularities in a subfloor upon which the flooring plank is mounted.
