Title (EN) ERASER CLEANING TOOL
(FR) OUTIL POUR NETTOYER UNE GOMME
Abstract:
(EN) A tool for cleaning the usable surfaces of an eraser and sharpening the tip thereof comprises two pairs of walls (3, 5 and 13, 15) having uneven surfaces (6 and 16) for sharpening an edge (25) of the eraser (20). The uneven surfaces have different grains so that they form a rough abrasive surface (7) and a finer abrasive surface (17). The tool has a generally elongate shape parallel to the central rib (4) and is provided with end walls (2, 12) for retaining shavings (26). Said walls are preferably sloped to allow several such tools to be stacked.
(FR) Cet outil permet de nettoyer les faces utiles d'une gomme et d'affûter sa pointe. Il comporte deux paires de parois (3, 5 et 13, 15) ayant des irrégularités de surface (6 et 16) aptes à rectifier une arête (25) d'une gomme (20). Les irrégularités de surfaces présentent des grains différents pour constituer une surface abrasive (7) grossière et une surface abrasive (17) plus fine. Cet outil est de forme générale allongée parallèlement à la nervure centrale (4) et il est muni de parois en bout (2, 12) aptes à contenir les déchets (26) de gomme. De préférence, ses parois sont inclinées pour autoriser l'empilage de plusieurs outils.
