1. An entanglement system for forming at least one entangled seam on a composite nonwoven textile having a first width, the entanglement system comprising:
a first entanglement station comprising:
a conveyance system having a surface adapted to advance the composite nonwoven textile in a material flow direction perpendicular to the first width;
a first actuator adapted to actuate a first entanglement head coupled to the first actuator; and
a first carriage coupled to the first entanglement head, the first carriage adapted to move in a first direction non-parallel to the material flow direction;
wherein a first entanglement footprint produced by the first entanglement head in the composite nonwoven textile has a second width in the first direction that is less than the first width.
