Abstract
Abstract A single, flexible, pressure-sensitive adhesive coated sheet having one or more co-terminal, V-fold liner tabs attached to portions of the adhesive coated surface; and tape pads formed from a plurality of such sheets. In this invention one leg of a V-shaped tab is adhered to the adhesive coated surface of the sheet. An unattached leg of the tab forms a handle which is easily grasped to facilitate manual separation of the tab from the sheet when it is adhered to a receptor surface.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
122 words
A single, flexible sheet comprising a backing having first and second surfaces; a coating of pressure-sensitive adhesive on the first surface of said backing; a folded liner strip forming a V-fold tab wherein the V-fold tab is prepared from polymeric tubing, one leg of said tab adhered to said pressure-sensitive adhesive on a portion of said backing, said tab extending to and coterminous with the peripheral edges of said sheet portion; the unattached leg of said tab hanging freely and forming a handle to facilitate manual separation of said tab from the sheet as the tab covered portion of said sheet is urged into contact with a receptor surface; said handle being identical in dimensions with said attached leg of said tab.
