  • Patent number: 4907825
    Abstract: 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.
    Type: Grant
    Filed: September 8, 1988
    Date of Patent: March 13, 1990
    Assignee: Minnesota Mining and Manufacturing Company
