An entanglement apparatus includes a controller and a nozzle rotatably mounted for rotation about a nozzle axis. An entanglement section is coupled to a fluid supply and defines openings positionable to face overlapped ends of the fiber tows. At least one of the openings extends along an angled direction relative to the nozzle axis to create adjacent or overlapping fluid distribution paths, and two or more of which are disposed in irregular intervals along the entanglement section and relative to another two or more of the paths. The controller regulates a preselected property of the fluid supply, including a rotation characteristic of the nozzle to randomize the paths. The apparatus directs the fluid through the openings and along the paths toward the overlapped ends of the fiber tows while the nozzle is rotating about the nozzle axis and while the fiber tows, other than their overlapped ends, are maintained stationary.
