Estimating the term…
A sheet including a layer of flexible polymeric material having a coating of repositionable pressure sensitive adhesive on a second end portion that is generally transparent when adhered to a substrate, while being free of adhesive along a visually distinctive first end portion. A pad of the sheets in a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets adjacent can be disposed in a chamber partially defined by a top wall having a slot through which the first end portion of the uppermost sheet projects. Relative movement is afforded between the top wall and the uppermost sheet to afford, as the uppermost sheet is pulled through the slot, alignment of the slot with successive portions of the uppermost sheet toward its second end as those successive portions are peeled from the stack. In a final relative position between the top wall and the uppermost sheet the slot is along the second end portion of that sheet and the first end portion of the underlying sheet to cause movement of the first end portion of the underlying sheet through the slot with the second end portion of the uppermost sheet to leave the first end portion of the underlying sheet projecting through the slot after the uppermost sheet is removed.
A sheet for the temporary marking of portions of documents comprising an elongate layer of flexible polymeric material having opposite major side surfaces and first and second opposite ends, and having a coating of repositionable pressure sensitive adhesive on a second end portion of one of said side surfaces adjacent said second end while being free of adhesive on both of said side surfaces along a first end portion thereof adjacent said first end, both of said end portions being adapted to be written on, said first end portion being visually distinctive, and said adhesive coated second end portion being generally transparent when adhered to a substrate.
A plurality of sheets each comprising a layer of flexible polymeric material, having opposite major side surfaces and first and second opposite ends, and having a coating of repositionable pressure sensitive adhesive on a second end portion of one of said side surfaces adjacent said second end while being free of adhesive on both of said side surfaces along a first end portion thereof adjacent said first end, said first end portion being visually distinctive, and said adhesive coated second end portion being generally transparent when adhered to a substrate, said sheets being releasably adhered to each other by said coatings of pressure sensitive adhesive to form a stack with adjacent ends of said sheets aligned and with the first and second ends of successive sheets in said stack being adjacent.
A plurality of sheets each comprising a layer of flexible polymeric material, having opposite top and bottom major side surfaces and first and second opposite ends, having a coating of pressure sensitive adhesive on at least a second major end portion of said bottom side surface adjacent said second end, said sheets being releasably adhered to each other by adhesion of said coatings of pressure sensitive adhesive to portions of the top surfaces of underlying sheets adjacent the first ends of the underlying sheets to form a stack with adjacent ends of said sheets aligned and with the first and second ends of successive sheets in said stack being adjacent, and having means for preventing adhesion of minor first end portions of said sheets adjacent said first ends to underlying sheets in said stack.
