Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
