Abstract

See full text

An abrasive or polishing sheet has indicia carried on its rear face overlaid by a translucent textile material providing a surface engageable by hooks, the material being adhered to the said indicia and their information content remain discernible through the said material. The sheet can be secured to a hooked surface of a carrier unit and can be removed therefrom and reused. The grit size indication is provided without needing to print the fabric. The textile material is a brushed, knitted nylon having less than 20 loops or curls per square mm. A carrier pad has a material to which the sheet can be attached. The material of the pad has inclined stalks extending therefrom which have unhooked ends. These features result in a very low peel strength between sheet and pad.
