Abstract
An air amplifier utilizing the coanda effect is disposed adjacent to a web of material to be cleaned. A relatively small volume of compressed air is driven from a slot onto a curved wall surface. The 'coanda effect' causes that compressed air to adhere to the wall, and causes a suction creating a relatively high-volume air flow upstream from the slot to be drawn along with the small volume of air adhering to the wall. The high-volume amplified flow of air is drawn along the surface of a web of material to be cleaned to entrain impurities from the web of material to be cleaned. A vacuum source is mounted adjacent to the end of the wall such that impurities are drawn into the vacuum source and removed from the area. In addition, ionized particles are directed into the relatively high-volume air flow to increase the cleaning efficiency of the system. The present invention provides a high efficiency web cleaning system that need not be mounted as close to the web as prior systems. In this way, it is practical for use in many applications that have not been adaptable to the prior art.
