ABSTRACT:
As a liquid is sprayed onto a sheet, some of the liquid is oversprayed beyond an edge of the sheet. A collector for collecting such overspray comprises a pan arranged below the edge of the sheet, and a vapor-retaining structure extending over the pan to define a plurality of narrow apertures which permit the overspray to pass into the pan, while resisting the passage of vapors upwardly through the apertures and back into the spray chamber. The vapor-retaining structure comprises a plurality of inverted V-shaped strips which are arranged parallel to one another such that the bottom edges of adjacent strips define the narrow apertures, the width of the apertures being in the range of about 1/32 to 1/4 inch. This apparatus can be used as a hazardous waste minimization effort for spray coating operations.
