The forming nozzle includes a converging passage, at least one first internal cavity in fluid connection with a first working fluid source, and a plurality of first holes fluidly connecting the at least one first internal cavity with a working surface of the forming nozzle. The plurality of first holes are further positioned and directed such that in passing through the plurality of first holes, the first working fluid conveys the fibrous bundle material through the forming nozzle in a transport direction. A guide pin is disposed along a central axis of the converging passage, the guide pin including an elongated body which tapers in the transport direction. A bobbin disposed downstream of the forming nozzle.
