Abstract
A system and method for adhering resin to the exterior of the bottles includes a coating section, a flash-off section, and a curing section. In the coating section, the bottles are dipped in a solution of resin and solvent. Only the exterior of the bottles is coated. The bottles are fed from the coating section to the flash-off section where they will be conveyed along a zig-zag path. In the flash-off section, air will pass over the bottles in order to remove solvent from their exterior. The bottles are then fed to the curing section where they pass in front of a plurality of ultraviolet lights. The ultraviolet lights will cure the resin on the exterior of the bottles.
