Abstract
A carbon copy set includes a sheet having an elongated edge. An elongated strip of material having an adhesive coating thereon extending longitudinally of the strip on one side thereof is attached to the sheet at its elongated edge by a first portion of the adhesive coating. The strip is disposed such that an elongated edge of the strip and a second portion of the adhesive coating are positioned beyond the elongated edge of the sheet. The sheet and the elongated strip together present a combined sheet having the second portion of the adhesive coating exposed on one side thereof between the elongated edge of the first sheet and the elongated edge of the strip. The set may also include another sheet having an elongated edge. The combined sheet overlies the last mentioned sheet and is attached thereto by the second portion of the adhesive coating such that the elongated edge of the second sheet and the elongated edge of the strip of the combined sheet coincide.
