Apparatus for spreading a plurality of co-traveling web portions of a cut web such that a defined spacing is produced and maintained between the web portions. The apparatus includes a pair of spaced, perforated plates for permitting the application of sub-atmospheric air pressure to both sides of the traveling web portions to remove particulate matter from both surfaces of the web portions. The web spreading and particulate matter removing apparatus are connected to move as a unit while maintaining the spacing of the perforated plates from the web.
