Method and apparatus for folding and cutting an interconnected web of

Abstract

An interconnected web of disposable diapers containing a pair of continuous, stretched strands of elastic aligned generally parallel to the direction of web travel, is folded along its length from a substantially flat condition to produce a C-shaped, transverse cross-section by means of a conventional board and guide folder. The C-folded web is maintained under tension during the longitudinal folding operation to keep the continuous elastic strands in a stretched condition, and the web is cut transverse to the direction of web travel without releasing the tension in either the individual diapers cut from the web or in the advancing web. Means are provided for transversely folding the individual diapers cut from the web about their midpoints while maintaining the elastic strands associated therewith in a stretched condition and the diaper under positive control. Because the advancing web of interconnected diapers is maintained under positive control at all times, the individual diapers severed from the web are cut in register with respect to one another. This is of critical importance in situations where the web of interconnected disposable diapers is comprised of a plurality of discrete, interconnected diaper segments rather than a continuous web of disposable diaper material having a uniform cross-section throughout its length.
