An apparatus for applying powder coating material onto large objects such as automotive, truck or other vehicle bodies includes a powder spray booth defining a controlled area within which to apply powder coating material onto the vehicle bodies, a powder kitchen located at a remote position from the powder spray booth, and, a number of feed hoppers located proximate the booth which receive powder coating material from the powder kitchen and supply it to automatically or manually manipulated powder spray guns associated with the booth. Oversprayed powder coating material is removed from the booth interior by a powder collection and recovery system which transmits the oversprayed powder back to the powder kitchen for recirculation to the powder spray guns.

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.
