Abstract
Folio reams are draped into discrete panels of paper or other wrapping material while in continuous motion along a horizontal path. The panels are fed from below so that the front, lateral and rear portions of each panel extend beyond the respective sides of the corresponding ream. The rear portions of successive panels are folded upwardly against the rear sides and thereupon forwardly against the top sides of the respective reams. The front portions of the panels are provided with films of adhesive and are folded upwardly against the front sides and thereupon rearwardly against the top sides of the respective reams so that their leaders overlie and are adhesively secured to the folded rear portions. The folding of front and rear portions is preceded by squaring of the reams and is followed by tucking and folding of front, rear and lateral portions of successive panels against the adjacent lateral sides of the respective reams.
