  • Patent number: 6688434
    Abstract: A conveyor and lubricating apparatus includes a conveyor and a dispensing device. The conveyor includes a conveyor surface and is provided for transporting items on the conveyor surface. Exemplary items that can be transported include plastic bottles, glass bottles, cans, and cartons. The dispensing device provides a spray pattern of a lubricant composition onto the conveyor surface. The dispensing device includes a nozzle that generates the spray pattern, a lubricant dispensing line that supplies the lubricant composition to the nozzle, a nozzle valve that opens and closes in response to the pressure conditions within the lubricant dispensing line to control flow of the lubricant composition to the nozzle, and a spray valve constructed to move between a first position and a second position, wherein the first position causes pressurization of the lubricant dispensing line and the second position provides depressurization of the lubricant dispensing line.
