ABSTRACT:
The invention relates to an apparatus and method for controlling the emission, and recovery, of volatile solvents. In particular, this invention relates to a type of finish material applying apparatus which has become known as a robotized spraying cabinet and to methods of operating such an apparatus. In accordance with this invention, materials sprayed through the spray head and which escape adherence to a sprayed articles impinge onto overspray directing members disposed adjacent the conveyor and between the conveyor and the reservoir, a quantity of solvent for the finishing materials is retained at a location adjacent the conveyor and supplying for use in cleaning the conveyor, and the overspray directing members and retained solvent to be supplied for cleaning are chilled and thereby the vapor pressure of the volatile solvent is reduced, whereby the volatile solvent is maintained in liquid form and control over the emission thereof is facilitated.
