Sleeve Lubricator

This machine coats round glass bottles with a lubricant after they have been sleeved to replace the properties of the cold-end coating. The machine consists of a double stacked rubber belt unit on one side of the conveyor, mounted opposite a large 'open cell' sponge.

A stainless steel manifold is inserted into the sponge and a metering pump ensures that it is impregnated with lubricant at all times. As the round glass bottles contact the rubber belts they are rotated against the 'open cell' sponge.

Due to the length of the unit the bottles emerge completely coated in the lubricant. The main benefit of this method over spraying is that the inside of the containers do not become contaminated with lubricant.
