A polymeric foam finishing pad (10) is made by attaching a dense array of individual foam members (11) to a suitable support substrate (14). The member (11) may be individually attached to the substrate (14) or attached to the substrate (14) by an intermediate foam strip (16) to which the members (11) are integrally joined. The foam members (11) are preferably individually inserted into a support substrate (14) and attached to the substrate by an adhesive layer (35). Each of the foam members (11) is preferably folded and inserted into a preformed opening (46) contained in the support substrate (14), such that each foam member (11) forms a pair of fingers (12) that extend from the front face of the support substrate (14). The outer tip (12) of each foam finger may be slit to define a plurality of contact tips, thereby increasing the amount of surface contact between the finishing pad (10) and the surface being finished.
L'invention concerne un tampon (10) de finition en mousse polymère fabriqué par fixation d'un ensemble dense d'éléments (11) individuels en mousse sur un substrat (14) de support approprié. L'élément (11) peut être fixé individuellement au substrat (14) ou fixé au substrat (14) par l'intermédiaire d'une bande (16) de mousse avec laquelle lesdits éléments ne forment qu'une seule pièce. Les éléments (11) en mousse sont, de préférence, insérés individuellement dans le substrat (14) de support et fixés audit substrat par une couche adhésive (35). Chacun de ces éléments (11) est, de préférence, plié et inséré dans une ouverture (46) préformée contenue dans le substrat de support, de sorte que chaque élément forme une paire de doigts (12) qui s'étendent depuis la face avant du substrat (14) de support. La pointe (12) extérieure de chaque doigt en mousse peut être fendue de façon à définir une pluralité de pointes de contact, ce qui augmente la surface de contact entre le tampon de finition (10) et la surface lustrée.
