Abstract
An apparatus for forming a shaped fibrous nonwoven structure including a delivery system adapted to provide a high speed composite stream comprising thermoplastic polymer fibers and a secondary material. The apparatus also includes a movable collection device having a collection surface which intersects the composite stream, and at least one deflector to mechanically redirect at least a portion of the composite stream. Further the deflector moves in synchronization with the movable collection device, such that the composite stream is collected on the collection surface forming a fibrous nonwoven structure having at least one non-linear edge.
