Abstract
Abstract A resilient flooring or carpeting is mounted on a slat-like structure. The individual slats are not bonded together and are securely fastened to the underside of the flooring. The floor material is sufficiently resilient to permit the flooring with the slats attached thereto to be rolled in a large roll. When the roll of material is laid out on a flat support, the individual slats abut adjacent slats and form a subfloor for the flooring which is bonded to the slats.
