摘要： A powder spray gun comrpises a tubular housing having ambient air flow passages located in the side wall thereof medially of the opposite ends. A pair of air flow amplifiers are mounted in the housing on opposite sides of the ambient air flow passages and are so oriented that compressed air supplied to the upstream one of these amplifiers, the so called suspension amplifier, is operable to draw ambient air into the outlet end of the suspension amplifier, and compressed air supplied to the downstream amplifier, the so called pattern amplifier, is operable to draw ambient air into the inlet end of the pattern amplifier. The amplifiers are secured within the housing by end caps which are sealingly secured onto the ends of the housing by bayonet pin and slot connectors.

摘要： An apparatus for forming a non-woven pad consisting of fibrous material in which highly moisture-absorbent particles are intermixed with the fibrous material throughout a predetermined portion of the thickness of the non-woven pad. The non-woven pad is formed atop a conveyor moving through a chamber which has a duct connected to a source of vacuum operable to draw fibrous material injected into the chamber onto the conveyor. A spray gun or an extension thereof is positioned within the chamber relative to the fibrous material atop the conveyor, and is operated to discharge moisture-absorbent material at a predetermined velocity, such that the moisture-absorbent material is intermixed with the fibrous material throughout preferably a center layer of the thickness of the non-woven pad while forming boundary layers on either side of the center layer which are substantially free of moisture-absorbent material. The spray gun preferably operated intermittently to form spaced, sharply defined areas along the length and width of the non-woven pad wherein each area has moisture-absorbent material interspersed throughout a portion of the thickness thereof.

摘要： A method and apparatus for forming a non-woven pad of fibrous material is provided in which highly moisture-absorbent particles and fibers of thermoplastic material are intermixed with the fibrous material throughout one or more predetermined portions of the thickness of the non-woven pad while maintaining other portions of the thickness of the pad substantially free of highly moisture-absorbent particles and/or thermoplastic fiber material. The non-woven pad is formed on one side of a conveyor moving through a forming chamber which has a duct connected to a source of vacuum operable to draw fibrous material injected into the chamber onto the conveyor. One dispenser discharges the highly moisture-absorbent material at a predetermined location relative to the fibrous material being drawn onto the conveyor, and at least one other dispenser discharges the thermoplastic fiber material into the chamber at a location to intermix the thermoplastic fiber material with the fibrous material and highly moisture-absorbent material being drawn onto the conveyor at the predetermined location, and/or to intermix the thermoplastic fiber materials with the fibrous material in areas of the thickness of the non-woven pad on one or both sides of the highly moisture-absorbent material.
