Abstract
Business forms having labels integral with the sheets there of (rather than riding piggyback thereon) are produced by applying a strip of transfer tape to only a portion of the second face of a sheet, with the adhesive of the transfer tape contacting the sheet, so that sheet material surrounds the transfer tape strip completely. Then a label is die cut from the first face of the sheet, preferably after the transfer tape is applied, within the area of the sheet overlying the transfer tape strip, without cutting the transfer tape backing. Indicia is at some point printed on the first face of the sheet. The label may be readily removed, with the adhesive from the transfer tape sticking to the label while the backing of the transfer tape remains in place. The strip of transfer tape is cut from a web, and then is transported with the adhesive face outward by a vacuum cylinder, until it moves into contact with a moving web. The web is ultimately formed into individual or continuous business forms, which may be multi-ply.
