Abstract: A method of forming a nonwoven fibrous web from multiple laps of staple fibers, the major proportion of fibers within each lap being substantially oriented in one direction. Laps of the staple fibers are fed into overlying relationship with the major proportion of oriented fibers in each lap disposed in the same direction. Air is entrapped between adjacent laps as they are fed into overlying relationship to create an air barrier between adjacent overlying laps. The overlying laps are spread transversely of the direction in which the major proportion of fibers are oriented, and fibers within overlying laps are reoriented transversely within the plane of the laps out of the direction in which the major proportion of fibers are oriented while maintaining the air barrier between the adjacent overlying laps. The laps are pressed together after the lap spreading and fiber reorienting steps to form a unitary nonwoven fibrous web and fibers of the unitary nonwoven fibrous web are then bonded together.
