Abstract: Structures are described that create spaces while installing anchor sheet and attachment piece subfloors, but which allow for the expansion and contraction of anchor sheets after installation. The structures may be used on either the attachment pieces, anchor sheets or both. In one embodiment, the structure is a deformable margin; in another embodiment, the structure is a pull-away strip.

Abstract: A method and apparatus for connecting anchor sheets to each other and/or to a floor. The approach includes using attachment pieces which fit into an area of reduced thickness of the anchor sheet which surround a cut away of the anchor sheet. In one embodiment, the attachment pieces are corners which overlap areas of reduced thickness on a number of anchor sheets.

Abstract: An anchor sheet subfloor that includes a laminate having an upper layer of relatively thin flexible rigid sheet material and a bottom layer of a relatively resilient cushioning material. The upper sheet layer can be formed of a plastic or polymer material. In one arrangement, the sheet can be cut and fit within the boundaries of a room and the sheet has sufficient rigidity and mass to remain without distortion or buckling within the room by free floating on the existing floor without substantial attachment to the floor. It can be possible for a sheet to be cut and fit on site to fit the contours of a room to form by itself or in combination with other anchor sheets a free floating smooth subfloor on which can be overlaid decorative covering pieces.

Abstract: Carpet tape for use with a carpet construction which uses a loop back and hook tape for installation. The tape includes a substrate having pressure sensitive adhesive on one of its surfaces and there are hooked areas on the same surface. The hooked areas are located on either side of the pressure sensitive adhesive for engagement of the loops of pieces of the carpet. The adhesive is located on an area of the substrate substantially free of hooks, and the hooked areas are spaced apart from each other, for adhesion to the underside of the carpet pieces along neighboring edges for formation of a seam between the carpet pieces.

Abstract: This invention relates to a method of installing wall to wall carpeting of a selected width over an underpad of a selected thickness by attaching hooked tapes of a thickness substantially equal to the thickness of the underpad along the perimeter of the area to be covered by the carpeting. The underside of the carpeting, which is substantially covered with loops, is then attached to the upper surface of the tapes through hook and loop technology. The hooked tape and the underpad are of substantially equal thickness so that the loops on the underside of the carpet will attach to the hooks on the upper surface of the tape. In a further aspect, the underpad has loops substantially covering its lower surface so that the underpad is attached to the floor by a second hooked tape of lower profile than the carpet tape which is used to attach the underpad to the floor.
