Abstract
Adhesive sheet assemblies are described comprising a continuous carrier in roll form, a series of longitudinally spaced adhesive sheets on the carrier, and at least one cut in the web defining, for each adhesive sheet, one cover piece cut from the carrier such that the cover piece has an outer peripheral edge within the first portion on the backside of the adhesive sheet, so that the cover piece may be separated from the web and retained on the first portion of the backside of the adhesive sheet when the adhesive sheet is peeled off the carrier due to adhesion between the cover piece and the adhesive sheet. Preferably, at least 40 percent of the total length of the outer peripheral edge of each cover piece is substantially in registration with the outer peripheral edge of the adhesive sheet to which it is adhered. Each adhesive sheet comprises a flexible polymer film, polymer-reinforced sheet or cloth and is capable of being removed from a substrate to which it is adhered without leaving an adhesive residue on the substrate. Kits for dispensing the adhesive sheet assembly, processes for making the adhesive sheet assembly and processes for printing the same are also described.
