Abstract
For the application of a coating material to an object, the coating material is conveyed along a conduit by means of an entraining gas. For good conveying conditions, the entraining gas is made to travel at high velocity. In order that the velocity of the coating material discharged at the coating zone is not excessive, a partial vacuum source extracts part of the entraining gas from a point upstream of the outlet, via a separate conduit. This results both in an improved rate of deposition of the coating material on the object to be coated and in a particularly uniform coating.
