Abstract
A device for powdering a product arranged on a transport, in particular for powdering new strip-shaped or plate-shaped glass by means of at least one application beam overhanging the transport, the application beam having a storage space supplied with a discharge slot on its bottom along the entire length of the beam and a feed device assigned to it, containing at least one driven roller. Loss of powder can be avoided and a clean operation can be achieved; by supplying several cover hoods near at least one lateral end of the roller, arranged next to each other, each being assigned to a narrow zone of the roller which cover hoods can alternatively be brought in cover position in which the circumference of the roller assigned to the discharge slot is covered.
