Abstract

Apparatus for automatically packaging folded towelettes wherein a flat web of sheet material is continuously fed from a roll or like supply vertically upwardly through a longitudinal folding device by feed rollers that grip the longitudinally folded web and move the leading end through a rotary knife station where the moving web is periodically severed to provide vertically disposed strips of predetermined length in succession in a first transverse fold station where a horizontally reciprocable blade engages and transversely folds each severed strip while thrusting it into a horizontal roller transport arrangement that feeds each transversely folded strip in turn to a second transverse fold station where a vertically reciprocable blade imparts the second transverse fold to the strip while thrusting it into an envelope.
