Abstract
This invention is related to suction nozzles having a center protrusion for stabilizing a continuous web for various web property measurements. Suction nozzles blow air out of the nozzle, yet produce a vacuum proximate thereto. Two nozzles are disclosed, a single sided sheet-contact stabilizer and a non-contact sheet stabilizer. An air-bearing may be formed between the end surface of the center protrusion and the moving web.
