A resilient flexible sanding sponge (20) including a foam backing layer (22) having a layer of abrasive particles (26) distributed along one of its major surfaces (24) that are adhered together and to the backing layer by a layer of flexible adhesive material. That high tear strength backing layer can either be (1) a layer of felted urethane foam; or (2) a layer of foam that encompasses a reinforcing material (30). When the backing layer is of felted urethane foam the layer of flexible adhesive material (28) can have a major structurally sound portion below the surface along which the layer of abrasive particles is positioned and a minor portion adhering the abrasive particles along that surface to leave large portions of the abrasive particles projecting above the layer of adhesive material where they can effectively abrade a surface over which the sanding sponge is rubbed.

L'invention concerne une éponge (20) de ponçage élastique flexible comprenant une couche de soutien (22) en mousse avec une couche de particules abrasives (26) réparties sur une de ses surfaces (24) principales, collées les unes aux autres et à la couche de soutien par une couche faite d'une matière adhésive flexible. La couche de soutien, qui présente une grande résistance au déchirement, peut être soit (1) une couche de mousse d'uréthane feutrée, soit (2) une couche de mousse enveloppant une matière de renforcement (30). Lorsque la couche de soutien est faite de mousse d'uréthane feutrée, la matière adhésive flexible (28) peut comprendre une partie principale solidement structurée en-dessous de la surface sur laquelle est positionnée la couche de particules abrasives, et une partie plus petite collant les particules abrasives sur cette surface afin de permettre à une grande quantité de particules abrasives de se projeter au dessus de la couche de matière adhésive, pouvant ainsi abraser efficacement une surface sur laquelle est frottée l'éponge de ponçage.
