ABSTRACT:
A pad assembly comprising a multiplicity of flexible sheets each having a band of repositionable pressure sensitive adhesive coated on its rear surface adjacent and spaced by a small predetermined spacing from a first edge. The sheets are disposed in a stack with the band of repositionable pressure sensitive adhesive on each sheet adhering it to the adjacent sheet in the stack; and a layer of padding compound is disposed over and adhered to aligned first edges of the sheets in the stack. The padding compound allows, after the band of repositionable pressure sensitive adhesive on the rear surface of one of the sheets in the stack is separated from the front surface of the adjacent sheet in the stack, that one sheet (and any sheets above it) to be pivoted away from that adjacent sheet while remaining adhered to the adjacent sheets. The small predetermined spacing between the band of repositionable pressure sensitive adhesive and the first edge of each sheet provides a tactile feel when the band of repositionable pressure sensitive adhesive on the rear surface of one of the sheets in the stack separates from the front surface of the adjacent sheet in the stack that signals the person peeling the sheet away that such separation has occurred, and allows that person to reduce the force he is applying to the sheet, thereby restricting inadvertent separation of that sheet from the padding compound. After a sheet is intentionally separated from the padding compound, the band of repositionable pressure sensitive adhesive on the sheet affords adhesion of that sheet to a vertical surface.
