Abstract: A continuous elastic ribbon is fed to a diaper assembly station in a stretched condition while, at the same time, an adhesive is continuously applied to the elastic ribbon. Simultaneously, absorbent batts, as well as webs of moisture-impervious batt sheet material and moisture-impervious top-sheet material are fed to the diaper assembly station. Further, and simultaneously, while the webs are traveling to the assembly station, the quantity of the adhesive applied to the elastic ribbon is changed so that there is substantially less adhesive in pre-determined isolated portions of the stretched elastic ribbon. At the assembly station, a stretched elastic ribbon is adhered to the moisture-impervious backsheet web along portions of the elastic ribbon which intervene the selected areas of the web while lesser quantities of the adhesive are located.

Preferably, adhesive is applied to or activated on the leading edge of such first label as it is held essentially stationary on a vacuum bed in slipping engagement with continuously driven belts.

Abstract: 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.
