ABSTRACT:
A system for applying a coating material to articles comprises a booth having a floor and walls, a coating material dispensing device for depositing coating materials onto the articles, a vent opening in one of the walls, an exhaust system coupled to the vent opening for pulling atmosphere from the booth, one or more filters positioned between the coating material dispensing device and the vent opening for collecting undeposited coating material entrained in the atmosphere being pulled from the booth, a collection opening in the floor for collecting undeposited coating material which falls to the floor, and a sweeping apparatus for sweeping undeposited coating material on the floor into the collection opening. The sweeping apparatus includes two arms rotatably mounted in proximity to the floor, a drive mechanism for rotating the arms in a circular path. The collection opening in the floor is located near the periphery of the circular path. The arms include flexible blades for wiping the floor as the arm is rotated in the circular path so that the undeposited coating material is collected and forced toward the periphery of the circular path and into the collection opening in response to rotation of the arms.
