A web stabilizer comprising:
- a surface adapted to be adjacent to a moving web of material moving in a web direction,
- wherein the surface includes a first gap adapted to receive and direct a first moving fluid in a first direction parallel with the web direction and a second gap adapted to receive and direct a second moving fluid in a second direction perpendicular to the web direction, such that the first moving fluid provides a stabilizing congruent force to the moving web and the second moving fluid provides a stabilizing transverse force to the moving web, and
- wherein the first gap is substantially lengthwise along the web stabilizer, and wherein the second gap is substantially widthwise along the web stabilizer.
