<p>A high-speed apparatus for applying material to cigarette paper during manufacture uses at least two independently operable, moving orifice devices, each positioned to deposit horizontal bands of material on a paper web at the dry end of a Fourdrinier wire. The resulting web may be cut into multiple webs, each web having a width corresponding to the effective width of a moving orifice device. Dynamic optical inspection apparatus evaluates add-on band uniformity, thickness, and/or spacing and adjusts operation of the apparatus accordingly. The apparatus can simultaneously produce both banded and unbanded paper for wrapping tobacco during cigarette manufacturing.</p> |
