Abstract
Abstract There is disclosed a novel stencil assembly employed in duplicating address and other information on cartons, packages, and the like. The assembly includes a stencil tissue or sheet, on one side of which is permanently secured a narrow ridigizing strip adjacent the top edge of the stencil tissue. A strip of pressure sensitive reusable adhesive is applied to the opposite side of the stencil tissue substantially coextensive with the narrow rigidizing strip. A carbon material covers the remainder of the opposite side of the stencil sheet. A narrow guardian strip engages the lower portion of the adhesive strip. A backing sheet removably engages the remaining upper portion of the adhesive strip. A modified structure includes a carbon sheet in lieu of the carbon on the back of the stencil sheet and the guardian strip, said carbon sheet having a perforation line facilitating tearing off of a substantial portion thereof to provide a guardian strip. The guardian strip and the retained carbon sheet segment are foldable over to cover the exposed adhesive strip bared by removal of the backing sheet.
