To eliminate the necessity for stapling together web portions which are derived, for example, from a rotary printing machine, and superimposed, and which should be joined together, one of the web portions is deflected in a separate path and has a strip of adhesive applied transversely to the direction of movement, for example by passing the web portion between a pair of rollers, one of which has adhesive applied thereto. The web is passed free from contact with the two rollers of the pair, and the uncoated roller, at least, is formed with a projecting strip providing an impression or counter strip to press the web portion against the adhesive coating on the other roller to thereby apply an adhesive strip thereon. The two web portions are then guided into contact with each other and folded in the folding apparatus transversely to the movement at a fold line (19). The projecting strip need not be continuous, but may be a row of projecting bumps or teeth (FIGS. 3, 4) which cooperate with similar bumps and teeth on the other roller, or with a strip. |
