ABSTRACT:
Method and apparatus for automatically packaging towelettes in envelopes positioned in succession at an insertion station wherein the longitudinally folded leading end of a web of absorbent towelette material is severed to provide successive strips of predetermined length, and each strip is folded transversely first to a J-fold condition wherein the longer leg of the J is about twice the length of the shorter leg, and the longer leg of the J of each strip is folded substantially about its midpoint to form a folded towelette of three times the original longitudinally folded strip thickness as it is being thrust into an envelope positioned in timed relation at the insertion station. The J-folded strip is transferred between the transverse folds by a conveyor comprising one or more pairs of driven rolls each pair defining a pass between them substantially equal to the thickness of a severed strip, and the rolls of each pair being relatively resiliently mounted to permit increased relative separation temporarily as for permitting passage of increased strip thickness. Where the web is of non-woven fabric the longitudinal fold is ironed under heat and pressure to enhance the fold prior to severing.
