  • Patent number: 7067182
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricating coating that is thermally cured at less than 200° C. or radiation-cured. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping, renewable lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide dry lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

  • Patent number: 6821568
    Abstract: The interface between a moving conveyor belt and a work piece can be lubricated using an air driven stream of finely divided droplets of a lubricant composition. Droplets of a preferred size are directed by the air stream onto the conveyor with little waste of lubricant off the conveyor. The lubricant provides a very low coefficient of friction and little or no stress cracking in the containers. Using a low pressure and low flow rate air stream in conjunction with a low flow rate liquid lubricant attains the useful particle size in the lubricant add on spray. The liquid lubricant is sheared by the effect of the air flow creating the desirable droplet size and pattern of lubricant on the conveyor.
