Described is a self-adhesive sheet for bonding and residueless detachment of a floor covering, especially a carpet, to and from a floor, especially parquet, having a backing layer made in particular of polymer film, which is coated on a top surface, facing the floor covering, and on a bottom surface, facing the floor, with a pressure-sensitive adhesive coating and, it being possible, but not mandatory, for the top surface at least to have a textile structure, the pressure-sensitive adhesive coating having a different adhesive strength on the two surfaces, such that the pressure-sensitive adhesive coating and/or the adhesive strength on the bottom surface is a fraction of that on the top surface and at least on the bottom surface is of substantially planar design.
L'invention concerne une feuille auto-adhésive permettant de coller un revêtement de sol, notamment une moquette, sur un plancher, notamment un parquet, et de le décoller sans laisser de résidus. La feuille comporte une couche support, constituée notamment d'une feuille plastique. La couche support comporte sur sa face supérieure, tournée vers le revêtement de sol, et sur sa face inférieure, tournée vers le plancher, une couche adhésive. Au moins la face supérieure comporte éventuellement, mais non nécessairement, une structure textile. La force d'adhésion de la couche auto-adhésive est différente sur les deux faces, de façon que la couche d'adhésif et/ou la force d'adhésion sur la face inférieure soit égale à une fraction de celle de la face supérieure et soit sensiblement régulière au moins sur la face inférieure.
