A tambour backing is adhesively secured to a back side of the slats to hold the slats together as a panel. The tambour backing is made of a material that is inextensible in the longitudinal and lateral directions, but flexible to permit bending at joints defined between said wood slats. There are clips or tabs affixed onto the back surfaces of the respective slats at the front ends. These extend about a half-inch beyond the forward ends of the respective slats. The tambour can be secured with a hot melt adhesive. The clips can be formed of rectangles of fish paper. The clips prevent the flooring adhesive from coming between the front ends of the slats of one panel slats and the rear ends of the next panel slats. The clips also help align the ends of the corresponding slats or fingers of the two panels.Field of SearchADHERED COPLANAR VENEER TILE-TYPE FACER; E.G., PARQUETWith additional discrete securing means Integral edge engaging spacing feature on tile UNDERLYING COMPRESSIBLE LAYER OR PAD (E.G., FLOOR SYSTEMS) Having integral key OPPOSED STRIP SECTIONS (BASEBOARDS) AND OUTWARDLY EXTENDING SUSTAINER With additional locking feature (e.g., fastener) Keys, mortises, or key and mortise on opposed edges or faces Key designed for four direction lock Parallel ribs and/or grooves | |
