Abstract
Air embossing systems, air lances and methods of air embossing fabrics produce fine detail, crisp transition between unembossed and embossed regions, and a high degree of uniformity across the width of an embossed fabric. The air embossing systems utilize air lances ( ) for directing a stream of air onto the embossable surface ( ) of a fabric ( ) that have at least one nozzle ( ) having an orifice dimension substantially less than that of conventional nozzles. The air embossing systems can also include air lance nozzles positioned in proximity to the embossable surface, nozzles with an orifice dimension that is substantially less than the nozzle length, nozzles in the shape of an elongated slit oriental across essentially the entire width of the fabric, air lances including a nozzle-forming component ( ) separable from the main body ( ) of the air lance to enable the nozzle to be positioned within close proximity to the fabric and to redirect air to be emitted such that a substantial fracti n of the air stream is directed perpendicular to the fabric surface, and air lances including baffles r air redirecting elements ( ) which deflect air to pass through the nozzle and nt the fabric surface at an increased angle, relative to the air lance longitudinal axis.
