Gauze pads ready for packaging are formed by drawing web material from a roll and then folding the same longitudinally into a vertical attitude. Nip rolls driven at a controlled rate, draw the web from a folding station and then into an air stream which is directed horizontally at the vertical web where a tensionless loop is maintained. The web then passes through a vertical support guide and then to a folding station where reciprocating blades push the web alternately right and left, the alternations being held against side plates by flexible wire pads to prevent the fold from being pulled out by the next alternation of direction. The folded web is then pushed past a cutter by successive alternations of added material, the now cut pads being further pushed into diverging trays for packaging.
