<p>Method and apparatus for coating mouldings consisting of fluidising the mouldings by means of a rotating spiral gas flow. A holder (A) containing the mouldings is provided with gas inlets (3). A gas flow through the gas inlets (3) brings the mouldings in a spiral rotating movement in a sphere (C) placed on holder (A). Coating material is sprayed in the apparatus by a tube (D), oscillated by the gas flow, on the whirling mouldings.</p> |
