Various embodiments include methods and machines for coating objects with a flowable coating mass, where the coating mass is applied to the objects. Excess applied coating mass is blown off from the objects resting on an upper run of a grid belt and conveyed by moving the upper run in a conveying direction. From undersides of the objects resting on the upper run and conveyed by moving the upper run in the conveying direction, the excess applied coating mass is blown off using at least one first gas jet which is blown out at a first blow-out position, that is arranged below the undersides of the objects and, with respect to the conveying direction, laterally beside the undersides of the objects.
